The California Energy Commission (CEC) Electric Transmission Line geospatial data layer has been created to display the electric transmission grid in California. When used in association with the CEC Power Plant and CEC Electric Substation geospatial data layers, viewers can analyze the geographic relationships with the electric transmission grids across utilities, counties and state. The transmission line data, as one of the CEC's critical infrastructure spatial data 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 the CEC staffs various analysis 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.
Data Dictionary:
Object ID: a unique, not null integer field used to uniquely identify rows in tables in a geodatabase.
Name: abbreviated transmission line owner and transmission line capacity in kilovolts (kV).
kV: transmission line capacity in kilovolts (kV), data structure is a text string.
kV (Sort): transmission line capacity in kilovolts (kV), data structure is a numeric double.
Owner: abbreviated transmission line owner name.
Status - last reported operational, proposed, closed, or unknown status of the transmission line.
Circuit - notes if the transmission line segment is a Single, double, or triple circuit. Null values are unknown.
Type - OH is overhead transmission lines, UG is underground, UW is underwater, null values are unknown.
Legend - a summarized categories of transmission line owner and transmission capacity value in kilowatts (kV) for map legend purposes.
Length (Mile) - the length of the transmission line segment in miles.
Length (Feet) - the length of the transmission line segment in feet.
TLine Name - the name of the transmission line segment reported to the California Energy Commission
Source - the data source used by California Energy Commission.
