SCE cGIS Consolidation: Network Data Acceptance Journey• Matured validation process and tools enabled data acceptance
• Business stakeholders were strongly engaged during the process
• Acceptance process was mostly automated
• Acceptance quality was benchmarked at 98%
• Numerous source data issues surface for further review(s)

Data Acceptance Parameter
AQL Examples of Quality Checks conducted Nature of checks
Network Connectivity (Geometrical)
100% 1. Physical connectivity in Circuits2. Logical connectivity in Structures3. Logical connectivity relationship
100% Automation checks
Data Model Compliance 100% 1. Relationship validation2. Mandatory field validation3. Business rules validations
100% automation checks
Feature Capture and placement, attributes capture, Cartography and Annotations
98% 1. Feature existence validation2. Feature placement rules validation3. Annotation placement rules validation4. White space validation5. Attributes capture rules and validation
Mix of automated, semi-automated and manual validations based on source type
Completeness check 100% 1. Validate feature capture for sampled locations Random sampling

cGIS Consolidation – Key Challenges
• Achieve business owner data buy-in
• Align two separate data systems (structural and electrical)
• Build a data system minimizing user change while protecting operational systems
• Enable IT (system) and business (data) alignment during development
• Assure ability to transition a current set of data upon final system cut-over

Change Management challenges and opportunities
Southern California Edison13
Change Management Area
Challenges Methods toaddress challenges
Management • Lead the need for change• Align the business to achieve the optimal
results• Support adoption of new systems
Align solution to need
Business • Enhance organizational productivity • Gain confidence in the component additions
to the systems o New Landbase o Integration of previously isolated data
Sufficient time in review and testing; hear and address concerns
IT • Support new processes associated with data management
• Gain confidence in the external code development
Leverage current processes – both sides grow together
SCE cGIS – Enables GRID Modernization Investments
• Enabler for planning, grid operations, metering, distributed generation management, situational awareness, and outage management
• Key to data quality improvements – Transformer-Meter connectivity; Critical-to-Outage management operations
• Establishes the framework for single instance of truth to enabling structural and electric functionality into single applications
• Drive grid modernization technology through new network channels
