Geospatial Management of Electric Transmission Projects with ArcGIS Applications

What Is A Capital Project?

• Capital Projects are major construction or replacement projects for existing transmission facilities. Project activities include: planning, engineering, land acquisition, permitting, etc.

• Southern California Edison (SCE) manages multiple capital projects distributed over our large service territory

SCE Service Territory

• 5,000,000 service accounts

• 55,000 square miles

• 16 counties

• 180 incorporated cities

• 10+ governing agencies

What Problem Did We Face?

• When working on capital projects, we experienced the following problems: • Lack of GIS standards

• Reliability in deliverables

• Communication

• Reporting

• Agency requirements

• Environmental resource management

• Field data collection consistency

How Did We Get There?

Capital Project Data Model (CPDM)

Single managed enterprise database model with standardized schema that can be shared across internal and external organizations.

1. Identified Internal Stakeholders

2. Obtained Standards from Stakeholders

3. Created GIS Schema Standards and Documentation

4. Implementation, Training, and Maintenance
