Strong Change Management Foundation
• Driving Operations based on GIS requires GIS data to be qualified in terms of –
• Completeness • Accuracy • Timeliness
• Technology plays a key role in ease of integration at a ‘systems/data’ level
• However, a major role is also played by definition of processes that ensure
quality of GIS data and support the integration between IT & OT • TPDDL has been successful in the implementation of it Smart Grid Vision
due to the Business Process Re-Engineering , Change Management and definition of robust processes for sustenance of data quality in it’s enterprise GIS
GIS data readiness for Operations
• Completeness - Field Change notifications • Challenge - to get sustained information from field regarding new installations
and changes • Approach -
• Definition of Notifications/Workflows spanning ERP, GIS and SCADA/DMS • Definition of templates for information exchange between field crew, GIS
and Operations groups • Definition of Checklists to ensure completeness of data
• Correctness - Data Update Correctness
• Challenge - Ensuring quality of GIS data at the time of update • Approach –
• Definition of tools/system checks that ensure connectivity consistency • Checks for mismatch between voltage/phase etc. • Ensuring quality and consistent attribute for Operations support
• Timeliness - Data Availability
• Challenge - Cycle time for GIS data update • Approach –
• Process interlocks & SLAs

• Text based addressing of areas
• No scope of area proximity analysis
• Electrification status manually maintained
• Separate address source in SAP, GIS not used
• Manual intervention required
Area Electrification status – the first decision point for new connection
