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

Geo Smart New Connection

Locational answers – by Geo-SMART applications

Is the area electrified?

How well established is the network ?

Any dues on premise?

New connection request

Area feasibility

Network feasibility

Commercial feasibility

The answers lie with the Location – the location is GIS
