Document Description
The Proposed Project would consist of the construction of an approximately 14.5-mile-long, double-circuit 230 kV transmission line consisting of overhead and underground segments to interconnect SDG&E's existing TL 23021 into the existing Suncrest Substation. The Proposed Project would also include modifications to the existing Suncrest Substation, including (1) installation of a 500/230 kV transformer bank and associated tertiary reactors, circuit breakers, disconnects, and communication equipment, and (2) construction of a 230 kV bay to accommodate the loop-in of TL 23021 to the existing Suncrest Substation. The proposed 230 kV transmission line, coupled with associated modifications to the Suncrest Substation, would create a loop to enhance system reliability.
