1.3.2 In interpreting and complying with the DSOAR, the Participants shall
take into account that:
(a) the Distribution System conveys electricity through its contractual
relations with the End-use customers, RESs, Generators, and the
Supplier of Last Resort;
(b) at such time that the ERC declares open access and retail
competition, licensed RESs will be free to conduct business within
the Contestable Market, and End-use customers will fall into one of
two categories: the Captive Market and the Contestable Market; and
(c) the physical characteristics of electricity necessitate a significant
degree of coordination between the Participants to ensure quality and
reliability.
1.4 ENERGY REGULATORY BOARD RESOLUTION NO. 95-21
SUPERSEDED
The Energy Regulatory Board’s (ERB’s) Standard Rules and Regulations
Governing the Operation of Electrical Power Services, Resolution No. 95-21, as
amended by ERB Order, Case No. 95-368, dated April 10, 2000, are hereby
superseded in their entirety by the DSOAR.
1.5 NONDISCRIMINATION
All DUs shall make available upon reasonable request all regulated services at
rates, terms and conditions that are just and reasonable and shall not unjustly or
unreasonably discriminate in the rates, terms, and conditions of service to
similarly situated customers.
A DU shall provide regulated services to non-affiliated persons at rates, terms,
and conditions that are in no way different from the provision of such services
for its own purposes.
1.6 GENERAL DESCRIPTION OF SERVICES
With unbundling and open access, the distribution utilities face unprecedented
change with respect to service and the customers they serve. The DSOAR are
designed to cover the various service combinations in the new DU environment

15
created by the EPIRA. The regulated DU shall be prepared to provide a variety
of services to the Captive Market and the Contestable Market. DU service to the
Captive Market will be similar to service provided before EPIRA but now with
unbundled rates, removal of cross-subsidies, separate connections policy for
End-users, and possible regulation under the Distribution Wheeling Rate
Guidelines (“DWRG”). DU services in the Contestable Market shall include the
possible provision of unbundled Distribution Wheeling Service (“DWS”) to
Retail Electricity Suppliers (“RES”), the Supplier of Last Resort (“SoLR”),
other DUs, and Generators, as well as Distribution Connection Assets and
Services (“DCAS”) to End-users and Generators, and SoLR services to
Contestable End-users. With the implementation of open access and retail
competition, the list of possible DU customers now includes End-users, RESs,
the SoLR, Generators, and other DUs.
Every DU under the supervision, control, and jurisdiction of the ERC shall
operate, maintain, and provide safe, reliable, adequate, efficient and continuous
electric service. Every DU shall, upon request, give its customers as identified
above, copy furnished ERC, all information and assistance pertaining to its
service in order to provide said customers reliable, efficient and economical
service.
1.6.1 DISTRIBUTION CONNECTION ASSETS AND SERVICES
DCAS relates to those facilities and related services dedicated to
completing the Connection Point of an End-user or Generator. DCAS is
the responsibility of the DU for End-users in both the Captive Market
and the Contestable Market. Article II provides the rules pertaining to
DCAS.
1.6.2 DU SERVICE TO THE CAPTIVE MARKET
The DU continues to provide all aspects of service to the Captive
Market. Article III provides the rules pertaining to service to the Captive
Market.
1.6.3 SUPPLIER OF LAST RESORT SERVICES
Unless otherwise determined by statute or Commission order, all
Distribution Utilities shall perform the duties and obligations as
Suppliers of Last Resort (“SoLR”) for the Contestable Market within
their respective franchise areas as more fully set forth in separate
guidelines related to SoLR service to be adopted by the ERC. SoLR
service is regulated by ERC as back-up supply to the Contestable Market
for the contingency that an End-user in the Contestable Market does not
have supply from a competitive RES. SoLR service is not service to the
Captive Market and is not RES service by the DU.
The SOLR will provide electric energy to End-users in the Contestable
Market who are not able to receive electricity energy from their retailer
for any of the following reasons:
(a) Failure of the End-user to choose RES;

16
(b) Inability of the End-user to find or retain a willing and capable
licensed RES;
(c) Inability of the End-user to otherwise self-procure supply.
(d) The RES has ceased to operate;
(e) The RES is no longer licensed;
(f) The arrangements for DWS between the RES and the DU have been
terminated;
(g) The RES is no longer permitted to exchange power through the
WESM; and/or
(h) The RES has given notice to the ERC that it will no longer provide
supply services.
In A through C of the above, except as specified otherwise herein, the
End-user will immediately be served by the DU as a SoLR customer
after meeting certain requirements as established or approved by the
ERC. SoLR Customers shall not be served as if it were part of the
Captive Market.
Because SoLR service is part of the Contestable Market but is not an
RES function of the DU, the method of regulating energy prices for
SoLR service shall not be based on approved purchased power
agreement costs, but instead the SoLR shall charge the relevant
competitive market-clearing WESM energy prices for the energy
consumed by a SoLR customer during all hours of the monthly billing
period. The relevant market-clearing WESM energy prices shall be
those prices that would have been paid by the SoLR customer as if it
were purchasing energy directly through WESM. The SoLR shall also
bill SoLR customers the last approved unbundled monthly Supply charge
for the relevant Customer Segment and pass through all approved
Distribution Wheeling Service, system loss charges, and metering costs
charged by the DU and transmission service costs charged by the
transmission provider. System loss charges shall be computed using the
same methodology used for the Captive Market and based on the energy
costs of the SoLR customer. All costs of SoLR service shall be
transparently disclosed in an unbundled fashion in the billing to End-
users taking SoLR service in the same manner as billings to the Captive
Market. The DU may file an application with ERC at any time for
approval of reasonable unbundled Supply charges and system loss
charges applicable to SoLR service.
In the event of a power shortage, the Participants shall follow WESM
procedures for such a contingency. The Supplier of Last Resort is not
intended to be a generator of last resort during such a contingency.
An End-user taking SoLR service shall make a deposit equivalent to two
months total estimated billing based on historical demand and energy
usage and all applicable unbundled rate elements for SoLR service. Said
deposit may be applied to past due bills, except when such amounts are
restrained under legal contest. Such deposit shall be fully refundable
upon termination of SoLR service with interest paid on the deposit at an

17
annual rate determined by the ERC, less any arrears that have accrued in
the customer’s account.
An End-user under contract with a competitive RES cannot receive
SoLR service without first satisfying all terms and conditions related to
their RES contract including any contract termination fees. An End-user
disconnected by an RES or a DU for non-payment cannot use SoLR
service until such customer pays in full any and all amounts including
any applicable interest due to the RES or DU.
Any DU costs related to SoLR service shall be completely borne by the
DU and the Contestable Market End-users who are SoLR customers and
shall not be borne by the Captive Market. Any costs related to
generation capacity and energy not reasonably necessary to ensure
continuous and reliable service to the Captive Market, shall not be borne
by the Captive Market.
In addition to this section, SoLR service must also comply with all other
applicable guidelines issued by ERC.
SoLR service is only designed to be a safety net for instances when End-
users in the Contestable Market temporarily do not have a contract with
an RES. The power costs paid by an End-user using SoLR service are
expected to exceed those possible from an RES with a balanced
purchased power strategy. With this in mind, End-users who will
become part of the contestable market are strongly encouraged to seek
out supply contracts well in advance of the opening of retail competition.
1.6.4 DISTRIBUTION WHEELING SERVICE (DWS)
DWS is the wheeling and conveyance of electricity over a DU’s
distribution system. Unbundled DWS shall be made available in a non-
discriminatory fashion to licensed RESs, End-users in the Contestable
Market, the SoLR, other DUs, and Generators. To be clear, the DU shall
provide DWS to its SoLR function under the non-discriminatory terms
and conditions of Article IV and subject to the Business Separation
Guidelines. Article IV provides the rules pertaining to DWS.

above or below the nominal voltage at any time when the service is
furnished.
(3) A greater variation of voltage than that specified above may be
allowed in case of emergency service or in a certain area where the
customers are widely scattered and the business done does not, in
the judgment of the ERC, justify close voltage regulation.
Exceptions. Variations in voltage in excess of those specified, caused
(1) by the operation of power apparatus on customer’s premises which
necessarily requires large starting current, (2) by the action of the
elements, and (3) infrequent and unavoidable fluctuation of short
duration due to station operation, shall not be considered a violation of
this section.
1.7.10 STANDARD FREQUENCY AND ALLOWABLE VARIATION
Every DU supplying AC shall adopt the standard frequency of sixty (60)
Hertz and shall maintain said frequency reasonably constant so that its
variation shall not exceed one (1) Hertz above or below the standard

1.8 LIMITS ON LIABILITY
1.8.1 LIABILITY BETWEEN THE DU AND END-USERS
These rules are not intended to limit the liability of a DU or Connection
Customer for damages except as expressly provided in these rules.

22
The DU shall make reasonable provisions to provide steady and
continuous DWS, but does not guarantee the DWS against fluctuations
or interruptions. The DU will not be liable for any damages, whether
direct or consequential, including, without limitation, loss of profits, loss
of revenue, or loss of production capacity, occasioned by fluctuations or
interruptions unless it be shown that the DU has not made reasonable
provision to supply steady and continuous DWS, consistent with the
Connection Customer's class of service. In the event of a failure to make
such reasonable provisions, the DU's liability shall be limited to the cost
of necessary repairs of physical damage proximately caused by the
service failure to those electrical delivery facilities of the Connection
Customer which were then equipped with the protective safeguards
recommended or required by the Distribution Code.
The preceding notwithstanding, the DU or the Connection Customer
may be held liable for failure to conform to the rules and standards set
forth in the Distribution Code and other applicable electrical codes
adopted in the Philippines. Furthermore, if damages result from
fluctuations or interruptions in DWS that are caused by the DU's or
Connection Customer's gross negligence or intentional misconduct, this
section shall not preclude recovery of appropriate damages when legally
due.
1.8.2 LIMITATION OF DUTY AND LIABILITY OF RES
An RES has no ownership, right of control, or duty to the DU,
Connection Customer or other third party, regarding the design,
construction or operation of the DU's DCAS facilities and distribution
system. An RES shall not be liable to any person or entity for any
damages, direct, indirect or consequential, including, but without
limitation, loss of business, loss of profits or revenue, or loss of
production capacity, occasioned by any fluctuations or interruptions of
DCAS or DWS caused, in whole or in part, by the design, construction
or operation of the DU's distribution system. The foregoing not
withstanding, an RES may be held liable for non-technical system losses
when found to condone, collude, conspire, or engage in the pilferage of
electricity or tampering with any meters or DU facilities.
1.8.3 DUTY TO AVOID OR MITIGATE DAMAGES
The DU and Connection Customer shall use extraordinary diligence to
avoid or mitigate its damages or losses suffered as a result of the other's
culpable behavior under subsection 1.8.1.
1.8.4 LIMITATION OF LIABILITY DUE TO FORCE MAJEURE
Neither the DU nor the Connection Customer shall be liable for damages
or losses resulting or arising from any Force Majeure Event.
1.8.5 EMERGENCIES AND NECESSARY INTERRUPTIONS
The DU may curtail or interrupt a Connection and/or DWS in the event
of an emergency arising anywhere on the distribution system or the

23
interconnected systems of which it is a part, which emergency poses a
threat to the integrity of its system or the systems to which it is directly
or indirectly connected if, in its judgment, such action may prevent or
alleviate the emergency condition. The DU may interrupt service when
necessary, in DU’s prudent judgment, for inspection, test, repair, or
changes in DU's Distribution System, or when such interruption will
lessen or remove possible danger to life or property, or will aid in the
restoration of DCAS and/or DWS.
The DU shall provide advance notice to the Connection Customer, if
reasonably possible. Such notice shall be made at least two (2) days
prior to said curtailment, reduction, or interruption and may be made by
electronic notice (such as facsimile, text messages, or e-mail) to all
affected Connection Customers or through radio broadcast, television
broadcast, or local newspaper with specific identification of location,
time and expected duration of outage. Such information shall also be
posted on the Customer Bulletin Board. In cases where such notice is
not reasonably possible, the DU shall submit a report to the Commission
containing the information and an explanation why such advance notice
was not reasonably possible. It shall likewise take other necessary
actions to minimize the effect of such curtailment, reduction, or
interruption to the Connection Customer.
A notice shall also be provided to those End-users for whom an RES has
provided notice to the DU that interruptions or suspensions of service
will create a dangerous or life-threatening condition on the End-user’s
premises. The End-user should notify their RES or the DU if a condition
exists on the End-user's premises such that a suspension or interruption
of service will create a life-threatening or dangerous condition.
The DU shall comply with all reporting requirements of the Distribution
Code, and in addition to those requirements, shall either issue a written
public notice published in a newspaper of general circulation in the DU’s
service territory and filed with ERC stating the precise reasons causing
the curtailment or interruption within seven (7) days, or deliver a written
report to all affected customers, any respective RES, and the
Commission within seven (7) days. The public notice or report may
cover more than one curtailment or interruption if there were multiple
occurrences prior to the seven-day deadline for the first occurrence.
Nothing herein shall prevent the DU from being liable if found to be
grossly negligent or to have committed intentional misconduct with
respect to its exercise of its authority in this rule.
All the Participants shall cooperate with each other, the ERC and any
other affected entities in the event of an emergency situation affecting
the delivery of electric power and energy or the safety and security of
persons and property. The Participants shall comply with the
instructions of the DU and provide all necessary information prior to,
during, and following an emergency declared by the DU in accordance
with the Distribution Code.

24
1.9 DESIGNATION OF DISTRIBUTION UTILITY CONTACT PERSON
For the purpose of establishing immediate and direct contact with the DUs, the
DU shall submit the name(s), contact number(s) and address(es) of responsible
official/s. The said contact person/s must have the authority to decide on
matters concerning all the activities mandated by the DSOAR. The DUs must
notify the ERC in writing should there be any change in their submitted
information.
1.10 DISPUTE RESOLUTION
A Participant may file a petition for dispute resolution with the ERC. Said
petition shall specify all matters in dispute and the parties involved. After the
Commission determines that the case falls within its jurisdiction, it shall
forthwith issue an order setting the date of the preliminary conference and
directing the defendant to file his answer/comment within ten (10) business days
from receipt of said order or before the date of said conference, whichever
comes earlier. Affirmative and negative defences not pleaded therein shall be
deemed waived.
Should the defendant fail to answer the complaint within the period provided
above, the Commission, motu proprio, or on motion of the complainant, shall
render judgment as may be warranted by the facts alleged in the complaint and
limited to what is prayed for therein.
Within five (5) business days after the termination of the preliminary
conference, the Commission shall issue an order stating the matters taken up
therein.
Within ten (10) business days from receipt of the order mentioned, the parties
shall submit the affidavits of their witnesses and other evidence on the factual
issues defined in the order, together with their position papers setting forth the
law and the facts relied upon by them.
Within thirty (30) days after the receipt of the last affidavits and position papers,
or the expiration of the period for filing the same, the Commission shall render a
decision. However, should the Commission find it necessary to clarify certain
material facts, it may, during said period, issue an order specifying the matters
to be clarified, and require the parties to submit affidavits or evidence including
the presentation of a witness on the said matters within ten (10) days from
receipt of said order. Decision shall be rendered within thirty (30) days after
receipt of the last clarificatory affidavits, evidence or the expiration of the period
for filing the same.
All pleadings to be filed shall be verified.
While these are pending with ERC, the status quo of cases involving violation of
contract shall be maintained.

approval of the ERC.
1.12 INVESTIGATION, INSPECTION, EXAMINATION AND TEST
The ERC or its authorized representative may at any time, conduct an inspection
and investigation of the operation of any DU or an examination and test of any
equipment operated for electric service. The refusal, obstruction or hindrance
by the DU or any of its employees to the investigation or inspection of its
service or examination or test of any of its equipment shall constitute a violation
hereof.
1.13 ACCIDENT REPORT
Every DU shall keep a record, in chronological order, of all accidents that may
occur in connection with its operation, their nature, causes and consequences,
and the measures taken to avoid their recurrence. A detailed report of all
accidents shall be submitted to the ERC on or before the tenth (10th
) day of each
month. Accidents which result in death or physical injuries shall be reported to
the ERC within twenty –four (24) hours from their occurrence.
1.14 ACCOUNTS
Every DU operator shall keep such accounts, books and other records as are
necessary to afford an intelligent understanding of its business. If a uniform
system of accounting is prescribed by the ERC for the electric industry, the said
system shall be observed. Every DU shall keep its books of accounts by the
double entry method.
1.15 DEPRECIATION
Every DU shall set aside annually from its earnings an amount for depreciation
purposes which shall be subject to revision by the ERC and shall keep amount in
a depreciation fund which shall be spent only in accordance with
Commonwealth Act No. 146, as amended, otherwise known as the Public
Service Act.
The ERC shall fix and determine the proper and adequate rates of depreciation
of the property of the electric utilities under its jurisdiction which will be
observed in a proper and adequate depreciation account to be carried for the
protection of stockholders, bondholders or creditors in accordance with such
rules, regulations and form of account as the ERC may prescribe. Said rates
shall be sufficient to provide the amounts required over and above the expense
of maintenance to keep such property in a state of efficiency corresponding to
the progress of the industry. Each DU shall conform its depreciation accounts to
the rates so determined and fixed.
1.16 SUBMISSION OF MONTHLY STATISTICS AND ANNUAL REPORT
Every DU shall as prescribed by the ERC submit the statistics on electric power

cost adjustments approved by the ERC) together with the supporting documents
corresponding to the previous month in accordance with the prescribed form.
Likewise, the DU shall file with the ERC on or before May 31st
of every year a
detailed report of its finances and operations corresponding to the previous year,
in accordance with the form prescribed by the ERC. Said annual report shall be
based on audited financial statement.
1.17 COPY OF DSOAR
Every DU under the jurisdiction and control of the ERC must keep on file in its
offices a copy of the DSOAR.
1.18 VIOLATION
Violation of any provision of the DSOAR shall be subject to the penalty which
the ERC, after giving the DU opportunity to be heard, may impose in
accordance with law.
1.19 GOVERNING LAWS AND REGULATIONS
The DSOAR is governed by the laws and pertinent regulations of the
Philippines and any dispute or proceeding arising out of the DSOAR shall fall
under the original and exclusive jurisdiction of the ERC.
1.20 SEPARABILITY
If, for any reason, any provision or part of a provision of the DSOAR is declared
unconstitutional or invalid, those provisions which are not thereby affected will
continue to be in full force and effect.
1.21 AMENDMENTS TO THE DSOAR
Nothing in the DSOAR is to be construed as precluding the ERC from issuing
other rules and/or guidelines pursuant to the EPIRA and the IRR for the purpose
of regulating the provision of services in respect of Distribution Systems.
1.22 EFFECTIVITY
The DSOAR shall take effect 15 days following its publication in a newspaper
of general circulation.

27
ARTICLE II
RULES PERTAINING TO
DISTRIBUTION CONNECTION ASSETS AND SERVICES
2.1 GENERAL
This Article governs the terms of access and provision of Distribution
Connection Assets and Services (collectively referred to hereafter as, “DCAS”)
by a DU to End-users, Generators, and other DUs, collectively “Connection
Customers”. This Article also applies to End-users receiving a Connection
unlawfully or pursuant to unauthorized use. A DU shall provide DCAS
pursuant to the terms and conditions herein to any potential Connection
Customer within the DU’s franchise service area requiring such service. An
RES is not a Connection Customer but may assist its RES customers in matters
pertaining to DCAS.
2.2 ENGINEERING STANDARDS FOR EQUIPMENT AND
CONSTRUCTION
The standards for Distribution Connection Assets and the construction of
connections shall be consistent with the Distribution Code. However, a
Participant may petition the ERC for the approval of standards related to DCAS
that may exceed those set forth in the Distribution Code. Standards exceeding
those in the Distribution Code shall not be enforced by the DU on others unless
specifically approved by ERC. In the event the DU believes it is necessary in a
particular case to make investments that exceed minimum standards, the DU is
allowed to do so but may only recover any additional costs after approval from
ERC.
2.3 STANDARD CONNECTION FACILITIES
For the dual purpose of establishing unbundled connection charges and
implementation of ERC policies regarding new connections for End-users, the
DU shall identify Standard Connection Facilities for each Customer Segment.
In identifying the Standard Connection Facilities, the DU shall include the
minimum facilities necessary to establish a connection for a typical customer
within the Customer Segment. The DU shall include its proposed Standard
Connection Facilities as part of its application for approval of Standard
Connection Charges.
2.4 STANDARD CONNECTION CHARGES
2.4.1 TRANSITION TO UNBUNDLED CONNECTION CHARGES
Within 180 days following the effectivity of the Customer Segment
Guidelines, every privately-owned DU shall submit an application for
the approval of unbundled Standard Connection Charges (SCCs) for
each Customer Segment, and any future general application to adjust
rates made by a privately-owned DU shall likewise include proposed
unbundled Standard Connection Charges pursuant to the methods set
forth herein. Any general application to adjust rates filed within 180

28
days following the effectivity of the DSOAR shall include the required
application for the establishment of unbundled SCCs. A DU shall not
implement or adjust SCCs without ERC approval to do so.
The unbundling of Standard Connection Charges is intended to be
revenue neutral in the sense that the costs or revenues related to SCCs
shall be removed from the unbundled distribution rates or revenue
requirement.
ERC’s policy regarding the establishment of Standard Connection
Charges for Electric Cooperatives will be prescribed in another set of
guidelines.
2.4.2 STANDARD CONNECTION CHARGE FOR EACH CUSTOMER
SEGMENT
Customer Segments shall be established pursuant to ERC guidelines and
each Customer Segment shall have a Standard Connection Charge based
on the Standard Connection Facilities for that Customer Segment. A
Standard Connection Charge shall be uniform across all End-users
within the Customer Segment. The DU shall bill for the Standard
Connection Charge to the same person or entity responsible for payment
of unbundled distribution service or DWS.
Applications for the approval of Standard Connection Charges shall
include all relevant studies and data necessary to support a Standard
Connection Charge for each Customer Segment.
2.4.3 METHODOLOGY FOR COMPUTING STANDARD
CONNECTION CHARGE
The methodology used to compute the Standard Connection Charge
(SCC) for each Customer Segment of a private DU shall use the
following formula:
SCC = [((WACC × INVEST) + DEP) ÷ BD] + [OM ÷ BD];
Where:
WACC is the ERC-approved weighted average cost of capital
for the DU;
INVEST is the Connection Asset investment at current costs for a
standard connection or typical End-user in the Customer
Segment. The DU may propose the inclusion of
working capital in INVEST provided that such proposal
clearly identifies the recurring expenses involved and
the timing of such cash flow;
OM is the current Operation and Maintenance Expense
associated with connections as attributed to that
Customer Segment;
DEP is the depreciation expenses associated with INVEST
based on straight line methodology and a depreciation
life to be approved by the ERC;

29
BD is the billing determinant for that Customer Segment as
proposed by the DU subject to ERC approval.
In coming up with the values in the above formula, the methodology to
be used is not an accounting-based unbundling approach. Instead this is
a bottom-up approach with the following steps:
Step 1: Conduct an engineering study to identify the standard equipment
and facilities required for connecting a typical End-user within that
Customer Segment.
Step 2: Once the standard equipment and facilities have been identified,
calculate the installed cost of the standard connection (INVEST) based
on current costs. The current costs of equipment and facilities shall be
supported by recent invoices and quotes from equipment vendors and a
labor cost study related to installation.
Step 3: Calculate the monthly depreciation expense (DEP) based on an
ERC-approved depreciation life applied to the installed cost (INVEST)
of the standard connection.
Step 4: Calculate a reasonable return using the DU’s proposed weighted
average cost of capital (WACC) applied to the installed cost (INVEST)
of the standard connection.
Step 5: Conduct a study to determine the Operation and Maintenance
(O&M) expense related to Connection Assets and Services
corresponding to each Customer Segment. ERC approval of SCC will
include the distinct approval of the stand-alone O&M charge for each
Customer Segment.
2.4.4 ALTERNATIVE METHODOLOGY FOR COMPUTING
STANDARD CONNECTION CHARGES
Upon full implementation of a DU’s Business Separation Plan (BSP) and
accounting separation between DCAS costs and other Distribution
System costs, the DU may modify the methodology specified in 2.4.3 as
follows.
Step 1: Compute a total DCAS revenue requirement based on the
separated DCAS accounting costs.
Step 2: Use the INVEST values for each Customer Segment calculated
in Step 2 of the methodology specified in 2.4.3, weighted by the number
of customers in each Customer Segment, to develop Customer Segment
allocation factors (or ratios).
Step 3: Multiply the allocation factors from the previous step by the total
DCAS revenue requirement to arrive at Customer Segment specific
DCAS revenue requirements.
Step 4: Compute the SCC for each Customer Segment by dividing
DCAS revenue requirement by the approved annual billing determinant
for the Customer Segment.

30
2.4.5 SUMMARY OF OPTIONS FOR ESTABLISHING STANDARD
CONNECTION CHARGES AND ADJUSTMENT OF
DISTRIBUTION RATES
At present, Distribution Connection Assets form part of the rate base
used to compute unbundled distribution rates. Therefore, in establishing
Standard Connection Charges, there must be a corresponding adjustment
to the unbundled distribution rates. The method used for making such
rate adjustment will depend on the approach followed in establishing the
Standard Connection Charges.
Option 1: The DU makes its initial application pursuant to section 2.4.1
for approval of Standard Connection Charges prior to a general rate case.
In such a case, the Standard Connection Charges, once approved by
ERC, shall be credited against the unbundled distribution charges on
each individual customer’s bill.
Option 2: The DU makes its proposal for approval of Standard
Connection Charges within a general rate case and follows the
methodology specified in 2.4.3. In such a case, the unbundled
distribution revenue requirement for a particular Customer Segment shall
be reduced by the revenue to be collected through the Standard
Connection Charges.
Option 3: The DU makes its proposal for approval of Standard
Connection Charges within a general rate case and follows the
methodology specified in 2.4.4. Under this methodology, the
Distribution Connection Assets and related expenses have been properly
separated from the unbundled distribution rate base and revenue
requirement. In such a case, a revenue requirement offset or adjustment
to the unbundled distribution rates is not required.
2.5 NEW CONNECTION POINTS OR MODIFICATION TO EXISTING
CONNECTION POINTS
2.5.1 GENERAL
Subject to securing the approval of the DU in the manner outlined in the
DSOAR and in accordance with the process set out in the Distribution
Code, a Connection Applicant may seek:
(a) A new Connection Agreement for a first Connection Point; or
(b) A modification to an existing Connection Agreement for a change in
an existing Connection Point or addition of a Connection Point, in
either case by submitting a Connection Application to the DU.
2.5.2 APPLICATION FOR CONNECTION
The Connection Applicant shall complete a Connection Application
provided by the DU in accordance with the DSOAR and Distribution
Code involving a new Connection Point or modification to an existing
Connection Point, containing all necessary information for the provision
of the required services.

31
2.5.3 COMPLIANCE WITH PROCESS AND NON-DISCRIMINATION
The DU and each Connection Applicant shall comply with the processes
set out in the DSOAR and the Distribution Code for processing of new
or modified connection arrangements. The DU shall process all requests
involving connections in a timely manner and shall not give preference
or discriminate between different Connection Customers or Connection
Applicants, subject to any reasonable or justifiable exceptions as may be
approved by ERC. Likewise the DU shall not give preference or
discriminate between Connection Customers or Connection Applicants
based on a Contestable Market End-user’s choice of supply.
2.5.4 LOCATION AND MAINTENANCE OF DU’S EQUIPMENT
The DU shall have the right, if necessary to construct its poles, lines and
circuits and to place its transformers and other apparatus on the property
or within the buildings of the customer, at a point or points convenient
for such purpose, and the customer shall further grant the right to the use
of suitable space for the installation of necessary metering equipment in
order that such equipment will be protected from damage by the
elements, or through the negligence or deliberate acts of any person(s).
When the delivery of energy for separate buildings or premises is
desired/necessary, a separate contract between customers and utility shall
be required for each point of delivery.
In case the public utility, pursuant to this section, erects poles and lines
on the property of a customer in order to be able to service him, it shall,
upon payment of just compensation to the latter, also have the right to
connect to said poles and lines any neighbour or neighbours of said
customer, who may thereafter also apply for service connections and
who cannot otherwise be connected or reached.
2.5.5 SERVICE DROP
An electric service drop is defined as the wires with the necessary
supporting structure between the distribution lines of the DU and the
service entrance.
All connections and disconnections of service shall be made by the DU.
Only one service drop shall be installed for each individual building,
except as allowed in the Philippine Electrical Code, duly certified by a
government authority.
The service drop shall normally be connected at the DU’s pole carrying
electric service facilities nearest the applicant’s premises. Length of
service drop is defined as the distance from the pole to the nearest point
of attachment or connection.
The service bracket shall be supplied and installed by the DU in all cases
except where it is to be attached to a building of masonry construction.
In case of attachment to masonry construction, the contractor shall
secure the bracket which is issued by the DU and install it during the
process of construction.

32
2.5.6 SERVICE ENTRANCE
Service entrance is defined as that portion of the customer's wiring
including all necessary conduits, cable and accessories which extends
from the customer's main entrance switch and/or DU's metering
equipment to and including the point of attachment to the DU's service
drop on the outside of the building/property line visible and accessible to
authorized personnel of the utility. The outside terminal of the
customer's service entrance must be located so as to enable connection to
the service drop at a point nearest to the DU's existing or proposed
electric service facilities.
Service entrance (cable or conduit) shall be exposed on the outside of the
building/property line visible and accessible to authorized personnel of
the utility and shall be in one continuous run from the service drop
terminal to the meter, except for large installations whose single or
combined kilowatt demand has been determined by the DU to require
installation of instrument transformers, in which case the service
entrance may be concealed. The instrument transformers and metering
channel, which are part of the metering facilities, are to be furnished by
the DU. The line side of the service entrance must be separated from the
load side as abovementioned. All conductors on the line side of the
service entrance including the neutral wire shall be installed in one
conduit. The service entrance shall terminate near the point of
connection to the service drop with not less than two (2) feet of wire
extended outside the weatherhead.
In cases of "accessoria" wiring, the service entrance cable or conduit
shall be installed in the same manner as for other building particularly
emphasizing the fact that the entrance cable or conduit be exposed and
seal-type "accessoria" boxes without fuses shall be used for each
separate service connection or group of service connections. Proper
fittings shall be used in joining the cable or conduit to the junction box.
The DU shall not require existing open wiring service entrance to be
changed or replaced with service entrance cable or conduit installation
except when there is remodelling of existing installation and/or in cases
of proven current diversion in the customers premises.
Service entrance shall meet the requirements of the Philippine Electrical
Code (PEC) or local and national government ordinances.
2.5.7 SERVICE SWITCHES OR BREAKERS
A safety switch or circuit breaker duly approved by the authorized
government agency must be installed on the load side of the meter. All
safety switches must be externally operated with fuses electrically
“dead” when the switch is in the “off” position.
2.5.8 UNDERGROUND SERVICE
Residential – Underground residential service, including the pole on
which said service is terminated, shall be provided, installed and

33
maintained by the customers in accordance with the specification(s)
prescribed by the PEC.
Non-residential – Installation of any underground facilities shall be
subject to the prior agreement between the customer and the DU.
2.5.9 GROUNDING
In case of three (3)-wire single-phase service, the neutral conductor of
each service entrance shall always be grounded to an existing
underground water system in accordance with the PEC. Driven grounds
or their equivalent shall be accepted only where an underground water
system is not available in or near any wired building on the premises.
2.6 MODIFICATIONS AND NEW PHYSICAL CONNECTIONS:
RESIDENTIAL
2.6.1 RIGHT TO EXTENSION OF LINES AND FACILITIES
In accordance with the Magna Carta, a residential End-user located
within thirty (30) meters from the distribution utilities’ existing
secondary low voltage lines has the right to an extension of lines or
installation of additional facilities, other than a service drop, at the
expense of the utility. However, if a prospective customer is beyond the
said distance, the customer shall advance the amounts necessary to cover
the expenditures on the facilities beyond thirty (30) meters.
2.6.2 REFUND
To recover the aforementioned advanced payment, the customer may
either demand the issuance of a notes payable from the distribution
utility or a refund at the rate of twenty-five (25) percent of the gross
distribution revenue derived from all customers connected to the line
extension for the calendar year until such amounts are fully refunded or
for five (5) years whichever period is shorter, or, if available, the
purchase of preferred shares. Revenue derived from additional
customers tapped directly to the poles and facilities so extended shall be
considered in determining the revenues derived from the extension of
facilities.
Distribution Connection Assets paid for through advances from
residential End-users shall be deemed plant in service in the accounts of
the DU. Unpaid advances shall be a reduction to plant in service. If
replacement becomes necessary at any time for any Distribution
Connection Assets paid for by residential End-users, the DU shall be
solely responsible for the cost of such replacement which shall become
plant in service in the accounts of the DU, and shall not require another
advanced payment from the connected residential End-users unless the
replacement is due to End-user fault.

34
2.6.3 DEDICATED TRANSFORMER
If it is necessary to dedicate a transformer to the service of a single
residential End-user due to the non-standard, large load of that customer,
the End-user shall pay the actual cost of the transformer and such
payment shall not be subject to refund and will be treated as a
Contribution in Aid of Construction (CIAC). This provision does not
apply if a dedicated transformer is part of the Standard Connection
Facilities for the End-user’s Customer Segment or in the case of
transformers which are dedicated to a single residential customer
because of the customer is in a geographic location where the
transformer capacity cannot be shared with other customers. In cases
where the line extension is greater than 30 meters, the transformer
dedicated because of the isolated nature of the customer shall be subject
to the refund process in section 2.6.2.
2.6.4 ENGINEERING AND DESIGN
The DU shall be responsible for the engineering, design, and inspection
of all line extensions required to provide electric service to a residential
End-user. The DU shall prepare the design and cost estimate attributable
to a line extension within thirty (30) business days following the request
of a residential End-user or prospective residential End-user and
submission of all necessary load data by the End-user. In making the
request, the End-user shall provide all information pertaining to load
characteristics required to develop the design or cost estimate. This
service shall be provided by the DU at no charge to the End-user but
instead will become part of the DU’s operation and maintenance expense
accounts for DCAS.
2.6.5 MINIMUM FACILITIES
In designing a connection, the DU shall only require the minimum
facilities that are commercially available and consistent with current
ERC-approved standards, which are necessary to provide service to the
End-user. This provision applies to both Standard Connection Facilities
as described in section 2.3, and connections requiring facilities in excess
of the Standard Connection Facilities. If the End-user, or another party
requests facilities in excess of that which is necessary to meet the End-
user’s power requirements, then all costs attributable to such excess shall
be at the requesting party’s sole cost and expense which shall be treated
as a CIAC. If the DU installs facilities in excess of that which is
necessary to meet the End-user’s power requirements and such
installations are necessary to accommodate anticipated growth of
additional customers, then all costs attributable to such excess shall be
paid for by the DU and treated as Electric Plant Held for Future Use.
2.6.6 NEAREST SOURCE
The DU shall design the line extension from the nearest existing source
of available capacity to the End-user’s delivery point along the shortest
practical route. The DU may, however, design the line extension along

35
an alternative route in anticipation of additional customers; and in such
situations, all additional costs attributed specifically to the alternative
route shall be at the DU’s sole cost and expense, and treated as Electric
Plant Held for Future Use.
2.6.7 ALTERNATIVE ROUTES
Subject to the agreement of the DU, the End-user may request that the
line extension be constructed along a route different from the route
designed by the DU, but the End-user shall be responsible for all costs
attributed to such route. Such incremental amounts paid by the End-user
shall not be subject to refund, and shall be treated as a Contribution in
Aid of Construction.
2.6.8 EASEMENTS
The DU shall design line extensions along existing rights of way
whenever such rights of way are available. With the exception of
residential End-users located within thirty (30) meters of the existing
Distribution System, the End-user shall provide to the DU at no cost any
rights of way for a line extension across property owned or controlled by
the End-user, or procure from other property owners, when such rights of
way are necessary and dedicated to connect the End-user. In the event
that the End-user cannot obtain the required rights of way, the DU may,
by powers of eminent domain or otherwise, obtain rights of way. With
the exception of residential End-users located within thirty (30) meters
of the existing Distribution System, all cash amounts required to procure
easements shall be advanced by the residential customer subject to the
refund mechanism stated in section 2.6.2. The End-user shall submit to
the DU all relevant invoices and proof of payment along with a sworn
affidavit from the End-user that the documents are true and accurate.
The DU shall immediately inform the ERC if it has reason to believe that
any invoices or proof of payment have been falsified and the ERC shall
investigate.
2.6.9 MODIFICATION TO EXISTING FACILITIES
If an End-user submits a request to have the DU modify, rearrange,
relocate, or remove any of the DU’s legally sited facilities for any
purpose that does not result in a net increase in demand or electricity
usage, the End-user shall be responsible for all costs attributed to such
work. Such amounts shall be treated as a CIAC not subject to refund.
For modifications to existing facilities that result in a net increase in
demand or electricity usage and are within the defined Standard
Connection Facilities for the End-user’s Customer Segment, the
associated cost of such modification shall be that of the DU. If the
modification results in facilities that are in excess of the Standard
Connection Facilities, the residential End-user shall advance such
amounts to be refunded later at a rate of twenty five (25) percent of the
gross distribution revenue derived for the calendar year for five years or
until such amounts are fully refunded, which ever period is shorter.

36
2.6.10 RIGHT TO PROCURE EQUIPMENT AND CONSTRUCTION
Connection Customers/Applicants shall have the right to select their own
contractor and/or equipment vendor for the equipment, construction and
installation of Distribution Connection Assets provided that the same
adhere to all requirements of the Distribution Code and any other
standards approved by ERC. A Connection Customer/Applicant wanting
to self-procure equipment and construction shall only select from
contractors that have been accredited pursuant to guidelines issued by
ERC. Residential End-users located farther than thirty (30) meters from
the DU’s existing secondary voltage lines who procure and pay for
services and equipment to construct their own connection shall be
eligible to receive a refund at the rate of twenty-five (25) percent of the
gross distribution revenue derived for the calendar year for five (5) years
or until such amount is fully refunded, whichever period is shorter. The
End-user shall submit to the DU all relevant invoices and proof of
payment along with a sworn affidavit from the End-user that the
documents are true and accurate. The DU shall immediately inform the
ERC if it has reason to believe that any invoices or proof of payment
have been falsified and the ERC shall investigate. Said refund shall not
exceed the DU’s proposed estimate for constructing the Connection
Assets or the actual cost incurred by the End-user, whichever amount is
lower. Because the amounts paid for the construction of a connection for
a residential End-user are subject to refund, a residential customer
utilizing the option to construct their own connection shall pay the
relevant Standard Connection Charge approved by ERC.
2.7 MODIFICATIONS AND NEW CONNECTIONS: NON-RESIDENTIAL
2.7.1 RIGHT TO EXTENSION OF LINES AND FACILITIES
A non-residential End-user has the right to an extension of lines or
installation of additional facilities at the expense of the utility insofar as
the equipment and facilities to be installed are within the levels found in
the Standard Connection Facilities definition used to compute the
Standard Connection Charge for that End-user’s Customer Segment.
2.7.2 NON-STANDARD CONNECTION
A non-residential End-user has the right to an extension of lines or
installation of additional facilities that exceed the Standard Connection
Facilities provided that the End-user pays for any facilities in excess of
the Standard Connection Facilities used to compute the Standard
Connection Charge for that End-user’s Customer Segment. Specifically,
the amount to be paid by the End-user shall equal the cost of the
connection less the cost of the Standard Connection Facilities. Such
payments for facilities in excess of the Standard Connection Facilities
are not refundable and shall be treated as a CIAC. The End-user only
paying CIAC on the amounts in excess of the Standard Connection
Facilities shall still pay the ERC-approved Standard Connection
Charges.

37
2.7.3 ENGINEERING AND DESIGN
The DU shall be responsible for the engineering, design, and inspection
of all line extensions required to provide electric service to a non-
residential End-user at the voltage level so desired by the End-user. The
DU shall prepare the design and cost estimate attributable to a line
extension within thirty (30) business days following the request of a non-
residential End-user or prospective non-residential End-user and
submission of all necessary load data by the End-user. In making the
request, the End-user shall provide all information pertaining to load
characteristics required to develop the design or cost estimate. This
service shall be provided by the DU at no charge to the End-user but
instead will become part of the DU’s operation and maintenance expense
accounts for DCAS.
A non-residential End-user has the right to procure engineering and
design services related to the development of a new or modified
connection. The DU shall provide all data necessary for the completion
of any studies related to construction of a new or modified connection.
An End-user self-procuring engineering and design services shall be
solely responsible for any related costs, and the design shall be
consistent with current ERC-approved standards.
2.7.4 MINIMUM FACILITIES
In designing a connection, the DU shall only require the minimum
facilities that are commercially available and consistent with current
ERC-approved standards, which are necessary to provide service to the
End-user. This provision applies to both Standard Connection Facilities
as described in section 2.3, and connections requiring facilities in excess
of the Standard Connection Facilities. If the End-user or another party
requests facilities in excess of that which is necessary to meet the End-
user’s power requirements, then all costs attributable to such excess shall
be at the requesting party’s sole cost and expense which shall be treated
as a CIAC. If the DU requests facilities in excess of that which is
necessary to meet the End-user’s power requirements and such request is
necessary to accommodate anticipated growth of additional customers,
then all costs attributable to such excess shall be treated as Electric Plant
Held for Future Use.
2.7.5 NEAREST SOURCE
The DU shall design the line extension from the nearest existing source
of available capacity to the End-user’s delivery point along the shortest
practical route. The DU may, however, design the line extension along
an alternative route when such route best serves the interests of the DU;
and in such situations, all additional costs attributed specifically to the
alternative route shall be at the DU’s sole cost and expense, and treated
as Electric Plant Held for Future Use.

38
2.7.6 ALTERNATIVE ROUTES
Subject to the agreement of the DU, the End-user may request that the
line extension be constructed along a route different from the route
designed by the DU, but the End-user shall be responsible for all costs
attributed to such route. Such incremental amounts paid by the End-user
shall not be subject to refund, and shall be treated as a Contribution in
Aid of Construction.
2.7.7 EASEMENTS
The DU shall design line extensions along existing rights of way
whenever such rights of way are available. The End-user shall, without
reimbursement, procure for the DU any rights of way for a line extension
across property owned or controlled by the End-user or others when such
rights of way are necessary to connect the End-user. In the event that the
End-user cannot obtain the required rights of way, the DU may, by
powers of eminent domain or otherwise, obtain rights of way at the sole
expense of the End-user.
2.7.8 MODIFICATION TO EXISTING FACILITIES
If an End-user submits a request to have the DU modify, rearrange,
relocate, or remove any of the DU’s existing facilities for any purpose
that does not result in a net increase in demand or electricity usage, the
End-user shall be responsible for all costs attributed to such work. Such
amounts shall be treated as a CIAC not subject to refund.
For modifications to existing facilities that result in a net increase in
demand or electricity usage and are within the defined Standard
Connection Facilities for the End-user’s Customer Segment, the
associated cost of such modification shall be that of the DU. If the
modification results in facilities that are in excess of the Standard
Connection Facilities, the non-residential End-user shall be solely
responsible for the costs associated with the incremental additional
facilities which will be treated as Contribution in Aid of Construction.
2.7.9 RIGHT TO PROCURE EQUIPMENT AND CONSTRUCTION
Connection Customers shall have the right to select their own contractor
and/or equipment vendor for the equipment, construction and installation
of Distribution Connection Assets provided that the same adhere to all
requirements of the Distribution Code and any other standards approved
by ERC. A Connection Customer/Applicant wanting to self-procure
equipment and construction shall only select from contractors that have
been accredited pursuant to guidelines issued by ERC. . If the facilities
paid for and constructed by the non-residential End-user become the
property of the DU, such facilities shall be treated as a Contribution in
Aid of Construction and shall not form part of the DU’s appraised value
or rate base. The non-residential End-user opting to avail of the right
under this section shall only pay the approved operation and
maintenance component of the relevant Standard Connection Charge of
section 2.4.3.

39
2.7.10 PROPORTIONATE SHARING OF LINE EXTENSION COSTS
Any End-user shall be allowed to connect to facilities treated as CIAC
paid by another End-user. An End-user connecting to facilities
previously treated as CIAC paid by another End-user within five (5)
years from the date of the first CIAC shall pay the DU a CIAC
equivalent to one-half of the CIAC paid by the previous End-user times
the proportionate ratio of the distance utilized by the newly connecting
End-user plus any added facilities necessary to connect the End-user that
are in excess of the Standard Connection Facilities. For new connections
in which two or more End-users previously paid CIAC, the newly
connecting End-user shall pay (1/(n+1)) of the CIAC paid by the
previous End-users times the proportionate ratio of the distance utilized
by the newly connecting End-user, where n equals the number of End-
users making the previous CIAC.
The DU shall return the CIAC paid by the newly connecting End-user,
less any added amounts for facilities necessary to connect the End-user
that are in excess of the Standard Connection Facilities, to the End-user
or End-users who originally made the CIAC in proportion to the relative
amounts originally paid by each.
2.7.11 CONTRIBUTION IN AID OF CONSTRUCTION
Following inspection for compliance with the Distribution Code, any
installed Connection Assets paid for by the End-user and treated as
CIAC shall become the property and maintenance responsibility of the
DU, except as provided for in the following section. Any facilities
treated as CIAC shall not be subject to refund by the DU and shall not
become part of the DU’s rate base or appraised property value. If
replacement of a connection paid for through a CIAC becomes
necessary, the DU shall be responsible for the costs of such replacement
which shall become part of rate base consideration. The End-user,
however, has the option to pay for the replacement.
2.7.12 OWNERSHIP OF CONNECTION ASSETS
Upon acceptance by the DU, all Connection Assets on the DU side of the
agreed-upon Connection Point shall be and remain the sole property of
the DU. Notwithstanding the foregoing, at the request of the End-user
and if the End-user paid for the connection facilities, the DU and the
End-user will identify those facilities, if any, that are not likely to be
used to serve others and where ownership of such assets by the End-user
will not compromise the DU’s continuing obligation to serve customers.
Upon identification of such assets, the DU and the End-user may, by
mutual agreement, designate an alternate Connection Point to
accommodate the End-user’s interest in owning the identified facilities.
Consideration of End-user ownership of said Connection Assets
hereunder will be given only if the End-user agrees to meet the following
conditions:
(a) The End-user shall, as promptly as possible, transfer ownership of
said facilities to the DU in the event that any portion of these

40
facilities become necessary to provide service to other Connection
Customers. Such facilities, however, shall then be subject to the
proportionate sharing provision of section 2.7.10;
(b) Facilities owned by the End-user will be restricted solely for the use
of that End-user;
(c) The End-user agrees to procure and pay for all necessary
maintenance services for the owned facilities; and
(d) Only those facilities that pass through private property may be
owned by the end-user.
2.8 CONNECTION OF A GENERATING FACILITY
2.8.1 INTERCONNECTION AND OPERATING AGREEMENT
A Generator shall execute an appropriate agreement with the DU
governing the interconnection and operation of generating facilities.
(a) Pro-forma agreements establishing the terms and conditions for
interconnections and operation with the DU’s facilities for each
applicable class will be provided to the Generator by the DU. Such
agreements may be modified by mutual agreement as necessary to
address specific interconnection requirements existing at the time of
the execution of the agreement.
(b) Generators having agreements executed prior to the effective date of
the DSOAR that govern interconnection and parallel operation with
the DU’s facilities shall be governed by the provisions of those
existing agreements.
(c) The agreement shall include any necessary requirements for
communications and communications facilities between the DU and
the Generator.
(d) Where a Distribution Impact Study (DIS) and/or Distribution Assets
Study (DAS) is required, the Generator shall be responsible for
paying to the DU all reasonable costs incurred by the DU in
performing such a study unless such operation has been requested by
the DU.
2.8.2 GENERATOR COMPLIANCE
A Generator shall ascertain and comply with all applicable Commission
issuances, Commission-approved requirements of the DU, and any local,
national law, that applies to the design, siting, construction, installation,
operation, or any other aspect of the Generating Facilities.
2.8.3 DESIGN REVIEWS AND INSPECTIONS
(a) For the purpose of understanding the connection requirements of the
Connection Applicant and to ensure that planned Connection Assets
are adequate, DU shall have the right to review the design of a
Generator's Generating Facility and Interconnection Facilities and to
inspect a Generator's Generating and/or Interconnection Facilities

41
prior to the commencement of parallel operation with DU’s
Distribution System. The DU may request a Generator to make
modifications as necessary to comply with the requirements of the
DSOAR and the Distribution Code. The DU’s review and
authorization for Parallel Operation shall not be construed as
confirming or endorsing the Generator's design or as warranting the
Generating and/or interconnection facilities' safety, durability or
reliability. The DU shall not, by reason of such review or lack of
review, be responsible for the strength, adequacy, or capacity of such
equipment.
(b) Generators shall not begin operation with the DU’s facilities for the
first time until their interconnection facilities have been inspected by
the DU and written approval is provided by the DU to the Generator.
Such approval may be withheld for noncompliance with the
requirements of the DSOAR and the Distribution Code.
(c) A Generator’s generating facility and interconnection facilities shall
be reasonably accessible to DU personnel as necessary for DU to
perform its duties and exercise its rights under any agreement
between DU and the Generator.
(d) Any information pertaining to Generating and/or User Development
provided to the DU by a Generator shall be treated by DU in a
confidential manner.
2.8.4 PRUDENT OPERATION AND MAINTENANCE REQUIRED
A Generator shall operate and maintain its Generating Facility and its
User Development in accordance with prudent electrical practices and
shall maintain compliance with Commission adopted standards for the
Generator. Said standards shall be those in effect at the time a Generator
executes the Agreement with the DU.
The DU may limit the operation and/or disconnect or require the

required will be furnished by the DU and installed by the applicant at a
location specified by the DU. The applicant shall furnish and install
meter boards, where required.
The meter must be installed in a clean place free from vibration and
where it will be easily accessible for reading and testing. Under no
condition should meters be located behind doors or where they can be
easily broken or jarred by moving furniture or equipment. Meters shall
be located on the outside wall of the building or private pole and shall
not be more than three (3) meters nor less than 1.52 meters mounting
height from the surface on which one would stand to repair or inspect the
meter.

52
Generally, meters shall be installed on the ground floor in suitable space
and on a suitable mounting for large commercial and apartment
buildings. However, upon request by the customer, the DU may allow
location of meter(s) other than the ground floor provided meter(s) are to
be installed and located at a common place accessible to DU's personnel
for inspection, reading and maintenance purposes at anytime and a main
check meter installed at a location specified by the DU to measure the
total electric consumption of the building. All service entrance and other
electrical facilities after the main check meter, except DU meters, shall
be owned and maintained by the customer. Space and mounting shall be
adequate to accommodate all metering facilities. Individual cutouts
and/or switches shall be at least one (1) meter of clear space in front of
the meter(s).
2.11.2 GENERAL INFORMATION ON METERING
Every DU shall inform its customers of the manner in which meters are
read, either by printing on its bills for each service, a description of the
method used in reading meters, by distributing booklets describing such
method or in any other suitable manner.
Each service meter shall indicate clearly the units of service for which
charge is made to the customer. In case the dial reading of a meter must
be multiplied by a constant to obtain the units of service, the constant to
be applied shall be clearly marked on the face or dial of the meter.
Where the quantity of service is determined by calculation from the
reading of the meter, the DU shall upon request supply the customer with
such information as will show clearly the method of determining the
units of service rendered.
Every DU shall instruct its meter reader when reading periodically the
meter installed in the premises of a customer, to leave in such premises a
record showing the date of the reading, the reading made, the previous
reading and the total consumption expressed in units of service used, as
read by the meter reader, and the signature over the printed name of the
meter reader.
Except as otherwise permitted for the Contestable Market in Article IV
of the DSOAR, the meter and the metering equipment are the sole
property of the DU and any changes in their location or arrangements
shall be made by the DU.
2.11.3 TESTING AND SEALING OF METER
No meter shall be placed in service unless it has been tested, certified
and sealed by the ERC.
The seal attached to the meter by the ERC is a warranty (1) that the
meter is an acceptable or accepted type and (2) that it operates within the
allowable limits of tolerance.

53
2.11.4 TEST OF CUSTOMER’S METER BY THE DU
Every DU shall, upon request of a customer, make a test in accordance
with ERC guidelines free of charge of the accuracy of the meter installed
in his premises making use of a meter standard duly tested and sealed by
the ERC. If it is found that the meter being tested is within the tolerable
limit of (+3%) at any load, the utility may assess the customer concerned
a testing fee based on the amount charged by ERC. A written report
showing the result of such test shall be furnished the customer.
2.11.5 WATTHOUR METER ACCURACY REQUIREMENTS
(a) No mechanical watt-hour meter that has an incorrect register
multiplier, watthour constant, gear ratio, register ratio or dial train, or
that registers on no load ("creeps") shall be placed in service or be
allowed to remain in service without adjustment and correction.
(b) All watt-hour meters regardless of make and type before being
placed in service, must be adjusted as closely as possible to the
condition of zero error. The tolerance of plus or minus two percent
(2%) is hereby fixed to allow for necessary variations.
(c) No watt-hour meter that has an error in registration of more than plus
or minus three percent (3%) at any load shall be allowed to remain in
service. However, no meter shall be pulled out without a replacement
meter so as not to disrupt the continuity of service.
2.11.6 DETERMINATION OF AVERAGE ERROR
In tests made by the ERC or the DU, the average error of a meter shall be
determined by the following method:
Ea = O.3ELL+ O.7EFL
Where Ea is the average error, ELL is the error at light load.
EFL is the error at full load.
Provided, however, that at the request of the customer or in referee cases,
this method may be modified by admitting tests at a third load. If, and
when in the opinion of the ERC, such load is more representative of the
ordinary use of the meter, in which case, the average error shall be
determined as follows:
Take one-fifth (1/5) of the algebraic sum of (1) error at light load, (2)
three times the error at normal load, (3) the error of full load.
In both methods, light load shall be taken from five (5) to ten (10)
percent of the rated test amperes of the meter, and full load, not less than
sixty percent (60%) nor more than one hundred percent (100%) of the
rated test amperes of the meter.
For normal load the following percentages of the several classes of full
connected installations may be used:

54
Percent
Residence and apartment building ................................ 25
Elevator service............................................................. 40
Factories (individual drive).theaters, club,
hallways, entrance, and general store lighting ........... 60
Restaurants, pumps, air compressors, ice
machines, and moving picture theaters ...................... 70
Sign and window lighting, blowers and battery ........... 100
In the event that a meter in service is found to have an average error of
more than the tolerance of plus two percent, the customer is entitled to a
rebate. On the other hand, in the event that a meter service is found to
have an average error of more than the tolerance of minus two percent
(2%), the utility has a right to ask for a refund from its customer.
In both cases, the period to be covered in the computation of kWh
variance should be six months. The rate should be based on the present
rate at the time of the discovery.
2.11.7 RECORD OF METER
Every DU shall keep an adequate record of each meter showing (1)
make, type and identification marks and/or number of meter, (2) names
and addresses of customers, dates when meter installed or removed, (3)
adjustment or repair made, and (4) ERC certification dates.
2.12 INTERCONNECTION BETWEEN DISTRIBUTION UTILITIES
2.12.1 GENERAL
Consistent with Section 23 (paragraph 4) of the EPIRA, DUs may
interconnect in instances where such interconnection helps achieve
economies of scale in operations, reliability of service, reduction in
costs, and other efficiencies. The terms and conditions of said
interconnection shall be incorporated into an interconnection and
operating agreement which is subject to approval by ERC.
2.12.2 INTERCONNECTION AND OPERATING AGREEMENT
Interconnecting DUs shall execute an appropriate agreement governing
the interconnection and operation of their respective Distribution
Systems. DUs having ERC-approved agreements executed prior to the
effective date of the DSOAR that govern interconnection and operation
shall be governed by the provisions of those existing agreements. The
agreement shall include any necessary requirements for communications
and communications facilities between the DUs. The
interconnection/operating agreement shall be mutually beneficial. The
interconnection and operating agreement is separate and distinct from
any DWS arrangements.

Service to the captive market shall include all unbundled services necessary to
maintain a regular supply of alternating current of approximately 60 hertz.
Supply to the Captive Market shall be provided by the DU throughout its
franchise service area.
3.2 THE MAGNA CARTA FOR RESIDENTIAL CONSUMERS
The Captive Market includes both residential and non-residential End-users.
Insofar as residential consumers are concerned, the DSOAR are intended to
complement the MAGNA CARTA FOR RESIDENTIAL ELECTRICITY
CONSUMERS, issued on June 17, 2004, and the GUIDELINES TO
IMPLEMENT ARTICLES 7, 8, 14, AND 28 OF THE MAGNA CARTA FOR
RESIDENTIAL ELECTRICITY CONSUMERS, issued October 27, 2004. The
Magna Carta remains in full force.
3.3 APPLICATION FOR CAPTIVE MARKET SUPPLY
Any End-user in the Captive Market may apply for service from the DU within
their franchise area. The DU has an obligation to serve that customer subject to
all terms and conditions of service and Commission rules including the DSOAR.
The customer shall execute a standard form of agreement prior to the furnishing
of service by the DU. A copy of the rate schedule and the terms and conditions
of service shall be furnished to the new consumers. The DU shall inform its
customers of any changes in rates, rules and regulations approved by the

information shall be included as an insert in the billing envelop or on the bill
itself of all customers who are directly affected by the change. Further more any
adjustment clause previously approved by the ERC shall be clearly indicated on
the monthly bill.
3.4 ESTABLISHMENT AND REESTABLISHMENT OF CREDIT
3.4.1 RESIDENTIAL ELECTRICITY CUSTOMERS
For the establishment of credit, residential electricity customers and the
DU shall follow the deposit and deposit refund requirements found in the
Magna Carta. A residential customer who previously established credit
under the Magna Carta by receiving a refund of deposit from the DU
shall not be subject to a new deposit requirement if the customer
discontinues one service location and establishes a new service location
within the DU’s franchise area. This applies solely to the original
account holder and is non-transferable. This provision does not apply to
additional service locations established by the residential customer. In
the event a customer establishes a new service location in addition to
existing service(s), a bill deposit shall be required on that new service.

56
A bill deposit previously refunded to the customer may be reimposed if
the customer defaults in the payment of his monthly bill. Once the bill
deposit is reimposed, he loses the right to refund the same prior to the
termination of his electric service. This provision also holds for a
residential customer who was not required to pay a deposit on a new
service contract.
3.4.2 NON-RESIDENTIAL ELECTRICITY CUSTOMERS
For the establishment of credit, non-residential electricity customers
shall submit a bill deposit to guarantee payment of bills. The amount of
the bill deposit shall be equivalent to the estimated monthly billing.
Provided that after one (1) year when the actual average monthly bills
are more or less than the initial bill deposit, such deposit shall be
correspondingly increased/decreased to approximate said billing. DUs
shall pay interest on bill deposits equivalent to the prevailing interest rate
for savings deposit as approved by the Bangko Sentral ng Pilipinas
(BSP).The interests shall be credited yearly to the bills of the customer
on the anniversary of the commencement of service.
The bill deposit shall be refunded within one month from the termination
of service provided all bills have been paid. A customer that has paid its
electric bills on or before its due date for three (3) consecutive years
may, however, demand for the full refund of the deposit prior to the
termination of his service. An application for deposit refund shall be
filed with the DU and the DU shall refund the deposit within one month
from receipt of such application.
All customers shall be exempt from the payment of meter deposits. In
cases of loss and/or damage to the electric meter due to the fault of the
customer, the customer shall bear the full replacement cost of the meter.
Within 90 days following the effectivity of the DSOAR, all DUs shall
submit a proposal to ERC on the methodology and timeline for the
refund of all existing meter deposits.
3.4.3 RE-ESTABLISHMENT OF CREDIT FOR ALL CAPTIVE
CUSTOMERS
An applicant, who previously has been a customer of the DU and had
lost satisfactory credit, must first pay any unpaid billed amounts from
previous service plus the relevant deposit requirement to re-establish
credit.
A customer who is subject to disconnection/termination and who
requests continuation of service shall be required to first pay any unpaid
billed amounts. The customer’s bill deposit shall be re-imposed and/or
adjusted in accordance with his average monthly bill for the preceding
year.

3.5.1 MONTHLY BILLING
Bills for service shall be rendered to each customer in the captive market
on a monthly basis, unless otherwise approved by the Commission.
3.5.2 METERED SERVICE
Except for unmetered streetlight or other flat rate service customers, each
bill for service issued by the DU shall be based on the reading of the
meter for each account of the customer and any applicable monthly
charge(s).
3.5.3 CONTENTS OF BILL
Bills to service customers shall conform with the format approved by
ERC. Each bill for service shall include the following:
(a) Any previous balance.
(b) The period covered by the current billing.
(c) Meter serial and company number.
(d) The date the bill was issued.
(e) The amount due for service provided during the current billing
period with the date upon which this amount is past due.
(f) All unbundled rate elements including any adjustment clause listed in
the specific sequence prescribed by ERC. Any additional rate
elements or changes in the name of rate elements shall first be
approved by ERC.
(g) All relevant meter readings for the first and last day of the billing
period.
(h) The total quantities of applicable billing determinants.
(i) The date the meter was read.
(j) The telephone number and address of the DU office where a
customer may obtain information concerning their bill or the service
provided.
(k) An emergency contact number.
(l) A notice stating that all disputes that cannot be settled by the DU to
the satisfaction of the customer can be elevated to the ERC. The
ERC contact number and email address for the Consumer Affairs
Service as provided by the ERC.
(m)Any notices, advisories, or announcements required by the ERC to
be placed on the bill.
There shall be shown on the bill such additional factors other than those
contained in the schedule of rates, as may be necessary in computing the
bill. It shall be indicated on each bill that copies of the schedules of rates
applicable will be furnished by the DU upon request.

58
Bills to flat rate service customers shall be rendered at reasonably regular
intervals and shall show the period for which the bills rendered,
reference to the schedule of rates applicable and the amount of the bill.
The number and kinds of units for which a flat rate bill is rendered shall
also be shown 'on the bill.
Any future modification to the contents of the bill is subject to prior
approval by ERC.
3.5.4 ESTIMATED BILLS
(a) Except as otherwise provided, if the DU is unable to obtain useable
meter data from a customer or to read the meter of a customer on the
date scheduled due to a Force Majeure event or any event beyond the
control of the DU, the DU may bill the customer based upon their
estimated usage for the billing period. Estimated billing should only
be allowed in case the meter fails to register the consumption of the
customer for an entire billing period or a portion thereof. Otherwise,
the meter reading must be done immediately after the said fortuitous
event ceases to exist.
(b) Any of the following methods shall be used in calculating a bill
based on estimated usage. These methods are listed in order of
priority.
1. The average daily usage of the customer during the portion of the
billing period registered by the meter applied to the remaining
days in the billing period;
2. The average usage of the customer during the preceding three (3)
months; or
3. The usage of the customer during the same month of the
preceding year.
4. If time of use rates and metering are applicable, then the
estimated bill shall rely on the relevant time of use load profile
data during the previous month.
(c) The DU shall print the word “Estimate” on each bill which is based
on estimated usage, and shall not issue more than two consecutive
bills to a customer based upon estimated usage. Following two
consecutive bills based on estimated usage, the DU shall either read
the meter during the next billing cycle and adjust the estimated bills
accordingly or take an initial meter read following the next billing
cycle as if service was starting anew and no charges, penalties,
arrears, or reconnection fees will be levied on the customer for the
skipped billing cycle.
(d) The DU shall adjust the estimated usage upon the first reading of a
meter after an estimated reading. Differential billing following
estimated usage shall be spread out symmetrically by the number of
months it was estimated without interest charges.

59
3.5.5 PRORATION OF BILLS
For bills rendered for periods less than 28 days, any fixed monthly
customer charges in the bill shall be prorated based on the ratio of
number of days in the billing period to the number of days in an average
billing period.
3.5.6 PAYMENT OF BILLS
Every DU may require that' bills for service be paid within a specified
time after rendition. When the billing period covers a month or more, the
minimum time allowed will be ten (10) days after rendition unless a
longer period is specified and upon expiration of the specified time,
service may be discontinued after due notice for the non-payment of
bills.
Bills will be rendered by the DU to the customer monthly in accordance
with the applicable rate schedule. Said bills are payable to collectors,
collection office of the area where the customer resides or at its
authorized banks within ten (10) days after the customer's receipt of the
said bills, unless a longer period is allowed. The word "month" as used
herein and in the rate schedule is hereby defined to be the elapsed time
between two succeeding meter readings but not exceeding thirty-one
(31) days apart.
Every DU operator shall issue to its customers receipts which shall be in
the form or model prescribed by the ERC. Provided, however, that the
DU operator must submit a sample of said receipts for the approval of
the ERC before adopting the same in its service.
It shall safely keep the duplicate or office stub of the receipts used and
shall not destroy them within five (5) years without authority from the
ERC.
3.5.7 ADJUSTMENT FOR BILLING
Billing errors resulting from pilferages committed by the customer shall
be governed by the provisions of RA 7832 or the Anti-Electricity
Pilferage Act and its Implementing Rules and Regulations.
Billing errors resulting from a defective/stop meter without any evidence
of tampering shall be governed by the provisions of these guidelines and
the Magna Carta for Residential Electricity Consumers.
In cases of other billing errors, the following principles shall apply:
(a) Refunds for overpayment shall be computed back to but not beyond
the date on which the error or omission commenced subject to ERC
approval.
(b) Payments for undercharge shall be computed back to the date on
which the error commenced, however, in no case where the error or
omission is due to the fault of the DU, shall a bill for undercharge be
computed for a period exceeding three (3) months.

60
3.6 BILLING DISPUTES
If a customer disputes any bill, charge or service, the DU shall record and
promptly investigate the matter and provide a written report to the customer.
Reporting to the concerned customer shall be made within fifteen (15) days
from receipt of such complaint. The DU shall inform the customer of their right
to file a complaint with the ERC.
3.7 REGULATED RATES FOR THE CAPTIVE MARKET
Every DU shall be strictly governed in its charges by the schedule of rates
prescribed by the ERC and shall not change, alter, or in any manner modify the
same without prior authority of the ERC and shall post a copy thereof in a
conspicuous place at its office. A DU may only charge rates or service charges
to the Captive Market that have been approved or otherwise authorized by the
ERC. The DU shall maintain copies of all approved rate schedules at each of its
office locations and provide access and copies to such rate schedules to any
person making such request at no charge to the person.

61
ARTICLE IV
RULES PERTAINING TO DISTRIBUTION WHEELING SERVICE
4.1 GENERAL
This Article governs the terms and conditions of the provision of Distribution
Wheeling Service (“DWS”) by the DU to Retail Electricity Suppliers (“RES”)
and Generators. Unless otherwise noted, references to RES shall be read to
include the SoLR. DWSs pertain to those services performed by the distribution
utilities (DUs) for the conveyance of electricity through the regulated
distribution system as well as the control and monitoring of electricity as it is
conveyed throughout the DU system from the points of receipt to the points of
delivery. The distribution system includes the electric lines, and other
equipment, including transformers and the meters, used in the delivery of
electricity. DWS also includes discretionary services, which are customer-
specific services for which costs are recovered through separately priced rate
schedules, with the recoverable discretionary charges duly approved and
authorized by the Commission.
The DUs shall provide DWS for delivery of electricity of the standard
characteristics available in the franchise area. The DU shall provide DWS at its
standard voltages. Requestors of DWS must obtain from the DU the phase and
voltage of the service available before committing to the purchase of motors or
other equipment, and the DU is not responsible if the requested phase and
voltage of service are not available. The standard Distribution System service
offered by the DU may be provided at the voltage level specified under the
appropriate service agreement.
The provision of DWS by the DU is subject to the terms of any service
agreements, terms and conditions of the tariffs and applicable legal authorities.
All charges associated with a DWS provided by the DU must be authorized by
the Commission and included as a tariff charge, as provided in the rate
schedules.
4.2 ELIGIBILITY REQUIREMENTS FOR DWS
An RES is eligible for DWS when the following have been met:
(a) the RES has been licensed by the Commission and/or otherwise has been
designated and authorized by the Commission to provide service to End-
users;
(b) the RES has executed any applicable agreements required by TransCo;
(c) the RES has executed any applicable agreements required by the WESM, if
it is a market participant;
(d) the RES has paid any application fee set as approved by the Commission;
(e) the RES has demonstrated the ability to operate within the system approved
by ERC for data exchange, interruption reporting, and service requests; and
(f) the RES has executed a DWS Agreement with the DU; or

62
(g) following all of the above, if the DU has failed to execute the DWS
Agreement although the RES has signed such agreement, the RES shall be
deemed eligible for DWS, and the DU shall commence DWS for the RES,
during an interim period by filing the unexecuted agreement with the
Commission for investigation into the reasons for non-execution by the DU.
4.3 GROUNDS FOR REJECTING DWS AGREEMENT
The DU may refuse to execute a DWS Agreement with an RES for only but any
of the following reasons:
(a) the RES has undisputed outstanding debts with the DU, the transmission
provider, or the WESM, as attested in a sworn affidavit from an authorized
agent of the entity to which the RES is indebted and such amounts are not
currently part of a formal dispute;
(b) the RES has failed to comply with credit requirements approved by the
Commission; or
(c) the RES has failed to meet any of the eligibility requirements set forth in 4.2.
4.3.1 REJECTION OF DWS AGREEMENT
Upon rejection of any DWS Agreement, the DU shall provide the
affected RES with written notice of rejection and shall state the grounds
for rejection.
4.3.2 ACCEPTANCE OF DWS AGREEMENT
Upon its acceptance of a DWS Agreement, or pursuant to an order of the
Commission approving a DWS Agreement, the DU shall execute the
DWS Agreement and shall file an original copy with the Commission,
shall provide one original copy to the RES, and shall maintain one
original copy for its own records.
4.4 RELATIONSHIP WITH RES’S END-USE CUSTOMERS
An RES is responsible for all contractual, service, and billing matters related to
their End-use customers including those pertaining to DWS, and the DU shall
not be responsible for monitoring, reviewing or enforcing such contracts or
arrangements. This does not, however, prohibit End-users from contacting and
contracting directly with the DU for Connection Assets and Services pursuant to
Article II of the DSOAR.
The foregoing notwithstanding, an RES may opt to have one or more of their
End-use customers contract directly with the DU for DWS.
4.5 METERING
4.5.1 TIME OF USE METERING FACILITIES
All DWS customers in the initial phase of the Contestable Market shall
have installed time of use metering facilities capable of measuring
energy use and demand in a fashion consistent with WESM energy
settlement intervals, and distribution and transmission demand charge
intervals. Any exceptions to this rule require specific ERC approval.

63
4.5.2 OWNERSHIP OF METERS
The person procuring the meter for a customer in the Contestable Market
shall have the first option of owning and maintaining the meters subject
to any applicable rules and regulations of ERC including but not limited
to the Distribution Code. In the event a meter is not owned by the DU,
the End-user shall execute an Agreement for Meter Ownership and/or
Access for Non-Company Owned Meters similar to that included in
Article VI of the DSOAR. The DU remains responsible for testing,
sealing, and maintenance of all meters, subject to ERC procedures,
regardless of ownership. All billing meters shall be located at the
exterior of the End-user’s premises in a place that ensures easy access by
the DU and RES. Immediate access by the DU to any meter within its
franchise area shall not be denied.
4.5.3 METER READING AND DATA DISSEMINATION SERVICE
The DU shall conduct meter reading and data dissemination as a
regulated service until such time as competitive metering services may
be approved by the Commission. Upon establishment of competitive
metering services, an End-user may select any person authorized by the
ERC to perform meter reading and data dissemination service.
4.5.4 REQUEST FOR ADVANCED METERING TECHNOLOGY
An End-user in the Contestable Market or an RES serving the End-user
may request a new meter or meter upgrades with advanced technical
capabilities to be provided by the DU provided that all costs related to
the new meter including upgrades are borne by the RES or End-user.
Similarly, an RES or an End-user can request an upgrade to the meter.
Should there be a request for a new meter or a communication device be
attached to the existing meter, the DU shall provide, install, test, and
maintain the requested metering or communication device in accordance
with ERC approved Other Charges of DU. All advanced metering
technology shall comply with applicable ERC standards.
4.5.5 RIGHT TO PROCURE AND INSTALL ADVANCED METER
EQUIPMENT
End-users in the contestable market and/or an RES contracted with the
End-user shall have the right to own advanced metering equipment and
select their own contractor and/or equipment vendor provided that all
requirements herein are met. All advanced metering technology shall
comply with applicable ERC standards.
4.5.6 ACCESS AND METER READING
The RES contracted with an End-user shall have read-only access for
purposes of reading a meter of that End-user. If End-use customer takes
DWS at primary distribution or transmission voltage, the DU shall meter
DWS at that voltage level. The DU is responsible for reading the meter.
If an actual meter reading is not obtained, the DU shall estimate the
meter reading for invoicing purposes as prescribed in Article 3.5.4. In

64
the case of meter malfunction, the historical load profile from the
previous month shall be reported and noted as such. The DU shall report
measurement data for a point of delivery as required by the ERC.
4.5.7 METER DATA EXCHANGE
The DU shall provide all data collected from a meter read to the RES
serving that customer within three (3) business days following the
scheduled meter read.
4.6 SUBTRANSMISSION
4.6.1 DELIVERY SERVICE PROVIDED BY OWNER OF
SUBTRANSMISSION
A qualified DU or consortium of qualified DUs that own
subtransmission facilities shall ensure nondiscriminatory provision of
unbundled delivery service over subtransmission to any user, whether
that user is connected or not connected to subtransmission, who wants to
wheel power over subtransmission. Subtransmission wheeling service
shall be in accordance with the terms and conditions of DWS covered by
this Article IV in its entirety and Article II on connections. Customers
connected to subtransmission may include DUs, Generators, End-users,
or an RES providing retail service to a connected End-user.
4.6.2 NON-IMPAIRMENT OF GENERATION CONTRACTS WITH
END-USERS
The obligation to provide DWS per 4.6.1 shall not in any way impair an
existing purchase power agreement or generation contract legally
executed between an End-user and a Generation Company, nor a future
purchase power agreement between an End-user and an RES in the
contestable market.
4.6.3 SUBTRANSMISSION COSTS AND RATES
The rates charged for DWS over subtransmission facilities shall be in
accordance with the rates approved by ERC.
4.6.4 END-USER IN THE CAPTIVE MARKET WITHOUT
SUFFICIENT GENERATION
Any End-user connected to subtransmission without a legitimate
purchased power contract sufficient to provide all energy requirements
and that End-user is not part of the Contestable Market, the End-user
shall be considered to be part of the Captive Market and shall be served
as such by the relevant franchised entity. Similarly, in the case of a
legitimate contract that has expired and that End-user is not part of the
contestable market, the End-user shall be considered to be part of the
Captive Market and shall be served as such by the relevant franchised
entity.

65
4.7 TRANSMISSION
4.7.1 CONTRACTING FOR TRANSMISSION SERVICES
An RES shall obtain required transmission services in one of two ways
as part of its service to a particular End-user connected to a distribution
system or subtransmission. The RES may opt to have the DU contract
with the Transmission Provider for the demand of the RES’ customers,
and the DU shall pass-through the related costs including any deposits to
the RES. Alternatively, an RES may execute a contract for transmission
services directly with the TransCo. If the latter option is selected, the
RES shall properly inform the DU providing DWS of this selection.
This provision does not pertain to transmission connection services.
4.7.2 APPLICABLE TRANSMISSION RATES
Regardless of which option is selected under 4.7.1, the amount paid for
transmission service by an RES or a Contestable Market customer shall
be based on approved TransCo rates and the billing determinants
metered for the individual customer’s Connection Point. In other words,
the transmission costs borne by the Contestable Market customer should
not be an allocation of the DU system-wide load.
4.7.3 ANCILLARY SERVICES
When the DU is connected to the transmission grid, an RES shall obtain
all required ancillary services from TransCo or through the WESM and
shall not be required to take ancillary services from the DU except as
may be selected as an option by the RES per 4.7.1. In the event a DU
connected to the transmission grid provides ancillary services which
benefit the Distribution System, compensation or credit to the DU and
the Captive Market for providing ancillary services shall be determined
pursuant to the WESM Rules when applicable.
For a DU that is not connected to the transmission grid, the DU shall
seek approval of unbundled ancillary service charges to ensure that both
the Captive Market and the Contestable Market share in ancillary service
costs in a nondiscriminatory manner. Such application for the approval
of unbundled ancillary service charges shall be filed with ERC no later
than 180 days from the effectivity of the DSOAR.
4.7.4 WESM REQUIREMENTS
An RES is solely responsible for meeting any applicable WESM
requirements. The DU shall not be responsible for any WESM
requirements pertaining to an RES or a Contestable Market customer
served by an RES.
4.8 BILLING AND RELATED CUSTOMER SERVICE
4.8.1 RES RIGHTS AND RESPONSIBILITIES
An RES is fully responsible for determining the billing methods for their
customers and payment of all obligations to other market participants.

66
As an option to the RES, the End-use customer of the RES may be billed
directly by the DU for DWS. An End-user in the contestable market is
responsible for paying their RES all amounts legitimately billed by the
RES but shall not be held responsible for any amount not paid by the
RES to other market participants.
4.8.2 DEPOSIT FOR DWS
The RES or Contestable Market End-user shall remit a deposit to the DU
equivalent to one month estimated billing for DWS based on the
historical demand of the End-user, or in the case of a newly connected
End-user, based on projected demand and subsequently adjusted after
one year of historical usage. Such deposit may be used toward unpaid
bills.
4.8.3 PAYMENTS
With the exception of payments that are the responsibility of the End-
user, the RES shall pay all amounts due to the DU, TransCo, WESM,
Generators, or other Participants within the timeframe specified in its
respective agreements or requirements. Failure to do so may be grounds
for license revocation pursuant to the RES licensing guidelines and
possible disconnection of the RES’s customers. Failure of the End-user
in the Contestable Market to make payments to an RES or the DU, when
such customer contracts directly with the DU, may be grounds for
disconnection.
4.8.4 FAILURE TO PAY AND DISCONNECTION RIGHTS OF THE
DU AND THE RES
In the event an RES fails to pay for DWS by the due date prescribed for
the service, the DU shall notify the RES that service under the DWS
agreement will be terminated in seven (7) days. If the RES fails to pay
within 48 hours following said notice, the DU shall send a copy of the
notice of disconnection to the RES’s affected End-use customers. Prior
to termination of service under the RES DWS agreement, the End-use
customer must either acquire supply from another licensed RES or
temporarily establish service as a SoLR customer to avoid disconnection.
If upon termination of service under the RES DWS agreement the End-
use customer has not acquired service from another RES or the SoLR,
the DU shall have the right to physically disconnect the End-use
customer. Payment may be made by the RES to the agent or employee
of the DU at the time of disconnection and the agent or employee shall
desist from disconnecting service.
In the event that an RES customer billed by the DU for DWS fails to pay
by the due date, a 48-hour notice of disconnection shall be sent to the
customer and the RES shall be informed of such notice. If the customer
fails to pay the amount within the 48-hour period, the DU shall have the
right to physically disconnect such RES customer. Payment may be
made to the agent or employee of the DU at the time of disconnection
and the agent or employee shall desist from disconnecting service.

67
In the event that an RES customer fails to pay the RES for services
rendered by the due date, the RES may send a 48-hour notice of
disconnection to the customer and the DU shall be informed of such
notice. If the customer fails to pay the amount within the 48-hour
period, the RES shall have the right to request that the DU disconnect the
RES customer, and the DU shall execute such request within 24 hours.
Payment may be made to the agent or employee of the RES at the time
of disconnection and the agent or employee of the RES shall advise the
agent or employee of the DU to desist from disconnecting service.
Any disconnection performed pursuant to this section is without
prejudice to any charges, interest, or penalties legally imposed.
4.8.5 CONTESTABLE END-USER COMPLAINTS AND DISPUTES
Any End-user in the contestable market with a complaint or dispute
related to service and billing shall be the responsibility of the RES
serving that End-user.
4.9 GENERATOR WHEELING IN THE DISTRIBUTION SYSTEM
4.9.1 DU RESPONSIBILITIES
A DU shall make available at non-discriminatory terms and conditions
unbundled DWS to generators that seek to wheel power into, out of, or
through the distribution system.
4.9.2 GENERATOR RESPONSIBILITIES
A generator connected to the distribution system that seeks to wheel
power out of the distribution system shall pay all applicable DWS
charges. A generator wheeling power into or through the distribution
system shall likewise pay the applicable DWS charges unless those
charges are paid to the DU by load-serving entities such as an RES or
another DU.
4.10 WHEELING FOR ANOTHER DISTRIBUTION UTILITY
4.10.1 THE RESPONSIBILITIES OF DU AS CUSTOMER
A DU shall make available at non-discriminatory terms and conditions
unbundled DWS to other DUs that seek to wheel power out of or through
the distribution system.
4.10.2 CUSTOMER RESPONSIBILITIES
A DU that seeks to wheel power out of or through the distribution
system shall pay all applicable DWS charges unless those charges are
paid to the DU by a generator or other load-serving entities such as an
RES.

68
ARTICLE V
GUIDELINES FOR ESTABLISHING REGULATED SERVICE RATES
5.1 GENERAL
The Commission issued its Uniform Rate Filing Requirements (UFR) on
October 31, 2001. Since that time, ERC policy regarding the setting of rates by
DUs has evolved, most notably with the implementation of the removal of cross-
subsidies and the adoption of the Distribution Wheeling Rate Guidelines
(DWRG). To further promote nationwide consistency in rate design for
distribution service, the Commission sets forth these guidelines herein. These
guidelines are intended to complement, not substitute, the UFR. The UFR
remains in full force until such time as the UFR itself may be revised by the
Commission.
5.2 UNIFORM RATE FILING REQUIREMENTS
The Commission hereby incorporates the UFR as part of the DSOAR. All DUs
shall adhere to the principles and methods set forth in the UFR, as may be
revised by the Commission, as well as any principles set forth by the
Commission in Decisions and Orders issued as part of UFR cases.
5.3 DISTRIBUTION UTILITIES OPERATING UNDER THE DWRG
5.3.1 GENERAL
The focus of these provisions is primarily rate design under the DWRG;
that is, the allocation of revenue requirements to Customer Segments and
the conversion of the revenue requirement for a particular Customer
Segment into the various rate elements paid monthly by the customers
within that customer segment.
The DWRG provides flexibility to expeditiously adjust rates between
Regulatory Resets subject to a maximum average price (“MAP”). The
MAP is a company-wide measure without much constraint on individual
rate elements.1
The intent in granting such flexibility is to promote
efficient DU operations; however, the Commission also intends to ensure
that use of such flexibility adheres to the policies set forth in the EPIRA.
Specifically, all DUs shall only charge rates that reflect the cost-based
unbundled structure set forth in the UFR. At no time may costs or
revenues that should be recovered from one unbundled function be
shifted onto other unbundled functions. The rate design shall be free of
inter-class subsidies. That is, costs or revenues that should be recovered
from one customer segment shall not intentionally be shifted onto other
customer segments. The Side Constraints set forth in Section 6.4 of the
DWRG shall not be used to justify the shifting of revenues from one
customer segment to other customer segments.
1
The DWRG, Section 6.4, sets forth Side Constraints for average prices charged to Customer
Segments that must be adhered to by DUs. The Commission adds to that provision here with rules
pertaining to rate elements.

69
5.3.2 GENERAL METHODOLOGY FOR CONVERTING AN
ANNUALLY ADJUSTED MAP INTO RATES
Adjustments made to a MAP during a Regulatory Period must be
converted by the DU into new rate elements. This section sets forth a
general methodology by which these calculations are to be made.
The general formula for a MAP is similar to that found in Article 3.5 of
the DWRG: MAP = (CR – RBR) / CQ
Where:
CR = The amount (expressed in PhP) billed to Customers of that
Regulated Distribution System, or other persons, for the
provision of either regulated services, or unregulated
services which utilize assets that form part of the regulatory
asset base for that Regulated Distribution System, by the
Regulated Entity that operates that Regulated Distribution
System, during the 12 month period ending on 31
December.;
RBR = Such portion (expressed in PhP) of the net income derived,
during the 12 month period ending on 31 December, from
each related business undertaking which is engaged in
directly or indirectly by the Regulated Entity that operates
the relevant Regulated Distribution System and which
utilizes assets that form part of the regulatory asset base for
that Regulated Distribution System (see Section 4.8.8),
being a portion that is determined by the ERC pursuant to
Section 26 of the EPIRA and that may vary as between
such business undertakings but which, for each such
business undertaking, does not exceed 50% of the net
income that is so derived from that business undertaking;
and
CQ = The total amount of energy (expressed in kWh) delivered
through the relevant Regulated Distribution System, during
the 12 month period ending on 31 December, to
Connection Points in respect of that Regulated Distribution
System, such amount of energy:
(a) being determined in a manner that is approved for this
purpose by the ERC; and
(b) as so determined being audited to the satisfaction of the
ERC by a person that is approved for this purpose by
the ERC.
Consistent with the DWRG Position Paper dated December 7, 2005, the
steps to calculate the rates for an Application Year are as follows:
a) Calculate the historical revenue earned from each Customer Segment
i for a historical year t (CRi,t).

70
b) Calculate the average historical rate for each customer segment over
the previous 12 months (
ti
ti
ti
CQ
CR
CS
,
,
, = ), where CQi,t is the energy
consumed by each customer segment i (kWh), during historical year
t.
c) Compute the projected revenue for the next year per customer
segment based on the historical rate and forecast consumption
( tititi FQCSCR ,,1, ×=+ ).
d) By adding the projected revenue for each Customer Segment, the
total projected revenue for the Application Year, based on historical
rates, is calculated. ( ∑ += 1,20 tiCRYRCR )
e) Determine the proportion of revenue to be recovered for each
customer segment based on the projected revenue. (
YRCR
CR ti
20
1, +
)
f) Compute the total revenue (TR) for the Application year by
multiplying the maximum average price cap (MAPt) with the
forecast energy consumption for the Application year.
( tt FQMAPTR ×= )
g) Allocate the total revenue requirement (TR) for the Application Year
to each Customer Segment (TRi,t) based on the proportion of
projected revenue from each Segment to the total revenue projected
as computed under item (e) above.
(
YRCR
CR
TRTR ti
ti
20
,
, ×= )
h) The new rate element for a Customer Segment is then based on the
revenue requirement allocation to that segment for the Application
Year, using the same rate design as before for that Customer
Segment, as approved at the time of the regulatory reset.
Implicit to this methodology is the fact that a new rate structure or
Customer Segment cannot be introduced during a Regulatory Period.
Such changes or the introduction of a new rate structure can therefore
only be made as part of the regulatory reset process.
Changes in the rates, to account for new required revenue allocations to a
Customer Segment, can therefore only be introduced by changing the
quantum of those rate elements that already exist for each particular rate
structure.
5.3.3 RATE DESIGN AND BILLING DETERMINANTS
The billing determinants to be used for calculating the rates related to a
newly adjusted MAP shall be updated based on the most recent data
available and shall be the same rate design approved in the last rate case

71
or Reset Process. For example, if all distribution function costs for the
residential customer segment were previously approved for recovery
through a kWh charge, the same design shall be followed in the adjusted
rates. That is, the DU cannot now change the rate design to recover such
distribution-related revenue through a customer-month charge. The
DWRG regulated DU may only propose rate design changes during the
Regulatory Reset Process, unless otherwise ordered by the ERC.2
5.3.4 REGULATORY RESET PROCESS AND RATE DESIGN
As part of the Regulatory Reset Process, the applicant shall include a
cost of service study in which the total amount to be collected (revenue
requirement) is functionalized and allocated to customer segments (this
is the UFR methodology). The company also must submit its proposed
rate design for each customer segment. This will establish the new
charges paid by customers until the next annual adjustment at which time
the methodology described above in 5.3.2 and 5.3.3 shall be applied.
5.3.5 MONITORING BY ERC
Between Regulatory Resets under the DWRG, the ERC shall
periodically monitor the rate design employed by the DU to ensure
consistency with these guidelines.
5.4 DISTRIBUTION SYSTEM LOSSES
Connection Customers and the DU shall handle system losses in accordance
