- 4. Data Warehouse (ONLY data required for high performing production reporting) Enterprise Nomenclature Data Lake (ALL data) Enterprise Nomenclature Data Translation Layer (MDMS/EI) Data Translation Layer (MDMS/EI) DMS & OMS Customer Data Smart Meter (metadata, readings) Asset Data (Location, config) Financial Data Data Historian SCADA DG metadata DG generation data HR Data Usual EDW process and structure Usual EDW process and structure Discovery and indexing Discovery and indexing Production Reports Projects Data Explorers (Engineers, Data scientists) Weather Data Misc. Sensor head ends Security Data Transmission Planning Data Maintenance Data Demand Response Data Transmission OE and Dispatch Data EMS Transmission Market Data IT Asset Ops Data IT Support Data Project Documents Marketing & Sales Data Catch-All Other Applications Email & chat logs Facility Data Fleet DataCopyright enSustain
- 5. Possible Point-To-Point Exceptions Purpose oriented connection. Example: oHistorian facilitates connection with SCADA o EMS SCADA connection is latency-sensitive Application requiring access to only one system oDMS applications running off of DMS data o Historian applications running off of Historian data Copyright enSustain
- 7. The Approach for Implementation Main Challenges Siloed data Solution Part 1: Standard Data Model Solution Part 2: Access to unified data Lack of analytics ideas Solution: Close partnership between IT and business Lack of budget Solution Part 1: Tax each new project Solution Part 2: Take baby steps Copyright enSustain
- 8. Necessary Condition for Success • At the beginning, implement the new mechanism, ONLY to serve the new requirements • Keep the existing connections working and unaffected • Eventually, some of the existing connections will be deemed not-required, by the business • The rest of the existing connections can be converted as part of application maintenance/overhaul/upgrade, but not in the beginning phase of the initiative Do NOT touch the existing and the working systems first • Do not try to implement all the necessary new components at once. • Good quality on small scope is better than mediocre quality on large scope. • It might require more overhead, but it is often worth. Scope the smallest possible piece and do it well Copyright enSustain
- 9. Possible Steps for Implementation A new data connectivity requirement comes in Identify the source system Define the enterprise nomenclature for the source system to align with industry standard Load MDMS/EI with the dictionary Configure EI to act as the data virtualization layer for the source system Release for production use with appropriate support mechanism Milestone: One project is now using this new mechanism for one source system Repeat 1 for every new data connectivity request As more source systems are brought into the scope, resolve discrepancies, if any arises The virtualization layer might experience performance issue as data load increases Research and Plan the Data Lake For every new data source implementation for the virtualization, implement the corresponding ETL for Data Lake Open the Data lake to users that prefer getting their data from the Data Lake (delayed but faster) over virtualization Implement Data Lake Analytics (say ML based on Spark) for a single use case Copyright enSustain
- 10. 3 MDMS, EI, Data Virtualization Copyright enSustain
- 11. Skip This Section Most utilities already use these systems and are familiar with them Copyright enSustain Hence, we will not discuss them
- 13. Why the Data Lake? • Some of the SOR systems might not be capable of handling as much data request • Access to some of the SOR systems might not be practical • Implementation of data quality check on virtualized data is hard (at the least, it would slow down queries) • Data travel over network: larger in a virtualized environment than in a Data Lake designed and used in a specific way • Bottom line: go for Data Lake only if it is foreseen to be needed If the MDMS/EI layer virtualizes the data, then access to standardized data across the enterprise is already established. What additional value does the Data Lake bring? Data Lake – not the immediate need, but the eventual destination Copyright enSustain
