the SLDC’s forecast for preparing its schedule or provide the SLDC with a schedule based
on their own forecast. However, if the generator(s)/QCA derive its schedule based on

8
SLDC’s forecast, they shall not take a plea that the error is due to erroneous forecast by
SLDC.
5.7. The QCA or individual generator, either injecting wind energy, solar energy or both,
connected to a substation shall not be permitted aggregation of more than one pooling
stations or individual generating station connected to a substation as the case may be.

05:30 hours to 19:00 hours of that day.
5.12. The declared Available Capacity (AvC) for a wind generating plant shall be applicable for

aforesaid mechanism, the security amount shall be worked out and the same shall be
provided by the QCA.
5.16. When the QCA is appointed by the generator for the purpose of these Regulations, the
responsibility for all the payments related to deviation charges payable on behalf of the

minutes basis, or
b) Permit access to the API link for getting the data from the meter to the QCA’s central
server to facilitate better forecasting.
c) Alternatively, allow the QCA to install additional meters on the existing CT/PT to
facilitate acquisition of real time data so that best schedule can be submitted to
SLDC.
12. Deviation Accounting
Deviation settlement for the State shall be governed by the following provisions:
12.1. Computation of Deviation Charges: Deviation charges shall be computed in the following
manner:
a) SLDC to calculate Absolute Error occurred in the scheduled energy and actual energy

generators based on these Regulations prepared by the SLDC for the pooling
stations/wind energy generators/solar generators, with consideration of the actual
deviation in the energy from scheduled energy made by the pooling station or
individual generator directly feeding energy in to the substation.

by the pooling substation or individual generator directly feeding to sub-station and
collect the deviation settlement charges from the entity concerned for the amount
payable by them as per the provisions of these Regulations.
d) SLDC is required to adjust the deviation settlement charges received from the
renewable energy generators/QCAs under these Regulations in the State Pool for
deviation charges payable / receivable. The said State DSM pool account is required
to be maintained as revenue neutral in accordance with current practice.
The above mechanism shall be applicable up to 31st July, 2019 without any financial
implications (as stated in Regulation 8 above).
