Pacific Gas and Electric's Hunters Point to Potrero
115 kV Underground Cable Project (A.03-12-039)
PG&E has filed an Application, (A.03-12-039), for a Permit to Construct (PTC), including a Proponent's Environmental Assessment (PEA), pursuant to GO-131D to construct electrical facilities with voltages between 50 kV and 200 kV. The proposed project will consist of a 2.5 mile 115 kV underground power cable line within the city of San Francisco that will connect the Hunters Point switchyard to the Potrero switchyard.
Using the CAISO California Grid Planning Criteria, PG&E transmission planners evaluated various transmission alternatives and concluded that constructing a new 115 kV underground cable from Potrero to Hunters Point is the most feasible and cost-effective means of adding reliability to PG&E's internal transmission network in the city. For example, construction of a new 115 kV underground cable from Potrero to Hunters Point would allow PG&E to transmit power generated at Potrero to Hunters Point for further distribution if the generation capabilities at the Hunters Point Power Plant failed, or would allow the load on the internal transmission network to be distributed to the Potrero to Hunters Point line if another line needed to be taken out of service for repairs without overloading the current internal system.
