California Electric Transmission Lines

The California Energy Commission created the Electric Transmission Line geospatial data layer to display the electric transmission grid in California. When used in association with the Energy Commission Power Plant and Electric Substation geospatial data layers, viewers can analyze the geographic relationships with the electric transmission grids across utilities, counties and the state.

The transmission line data, as one of the Energy Commission’s critical infrastructure spatial datasets, will be used to:
1. Support the CEC/STEP/Strategic Transmission Planning and Corridor Designation Office in corridor study and transmission line siting;
2. Support analysis by CEC staff by providing general geographic reference information;
3. Enhance communication between and among government agencies on emergency management, resource management, economic development, and environmental study;
4. Provide illustration of critical infrastructure spatial data to the public or other agencies in hard copy format.
