Title

Gates 500kV Dynamic Reactive Support Project Final MND

Description

The Project would be located in unincorporated Fresno County upon and surrounded by rural agricultural lands with existing transmission infrastructure, utility-scale solar energy generation facilities, and scattered rural residences in the vicinity of the Project site. The Project would involve construction of the Orchard Substation containing two static synchronous compensator (STATCOM) units (devices used to regulate voltages for transmission networks and assist in ensuring reliable operation of transmissions systems in proximity to a substation) and ancillary components immediately north of and independently connected to the existing PG&E Gates Substation. The Project would support the regional transmission system by providing voltage support and grid stability, which would facilitate the reliable operation of the extra high voltage transmission system proximal to the Gates Substation. The purpose of the Project is to provide dynamic reactive support at the PG&E Gates Substation, a 500 kV and 230kV level regional substation. Connection to the PG&E Gates Substation would require PG&E to construct and operate two single-circuit 500 kV interconnection transmission lines from the Gates Substation 500 kV bus to the Orchard Substation 500 kV take-off towers.
