PG&E S-238 Hinkley Compressor Station Electrical Upgrades Project

Application No. A2504004

Last Update: April 10, 2025




 
Welcome to the California Public Utilities Commission (CPUC) website for the California Environmental Quality Act (CEQA) review of Pacific Gas and Electric Company's (PG&E) S-238 Hinkley Compressor Station Electrical Upgrades (Project). PG&EC filed an application for a Certificate of Public Convenience and Necessity (CPCN) for the Project on April 9, 2025 (CPCN Application No. A2504004). A summary of the Proposed Project is provided in the following section.

This website provides access to public documents and information relevant to the CEQA review process. Information about each project review phase will be provided in the following sections once available.


Summary of the Proposed Project

The Project will replace the electrical distribution system within PG&E’s Hinkley Compressor Station to increase reliability, maintainability, and operational safety. Because of its age, the electrical distribution system is at increased risk of failure, which will impact operation of the station and movement of gas along one of PG&E’s major gas transmission systems. Much of the electrical distribution equipment is obsolete, requiring specialized training, procedures, and personal protective equipment to maintain safe and reliable operation. Inspection and maintenance on an aging system is also complex and inefficient. The project upgrades will enable standard safety procedures and operation, inspection and maintenance efficiency, and cost savings.

PG&E’s existing gas transmission system will not be modified other than the station’s electrical distribution equipment upgrade. The station’s aging electrical equipment (switchgear, MCCs, and load center) will be removed and replacement equipment (switchgear and MCCs) will be installed. Some MCCs will be modified instead of being replaced. New and replacement equipment will either be connected to existing conduit or cable, or new conduit and cable will be installed as part of the project. Existing electrical distribution equipment, conduit, and cable between the switchgear, MCCs, and load center is expected to be removed, disconnected, or retired in place. No other gas system features will be added, modified, removed, disconnected, or retired in place.

The project will not change existing gas transmission capacities or modify station operation function other than increasing safety and reliability associated with the electrical distribution system. The proposed project is not phased and does not include future plans. The project will not change the gas transmission system layout, the users, or the area served.
