Corby Energy Storage, LLC (applicant), proposes to construct, own, and operate the Corby Battery Energy Storage System Project (project). The facility would be constructed on an approximately 40.3-acre privately owned parcel (Assessor’s Parcel Number 0141-030-090) southwest of the intersection of Kilkenny Road and Byrnes Road in Solano County, California. The project would include a 300-megawatt (MW) battery energy storage system (BESS), associated project substation, inverters, and other ancillary facilities, such as fencing, sound barrier, roads, retention basins, storage containers, and a supervisory control and data acquisition (SCADA) system. The project would connect to the Pacific Gas and Electric (PG&E) Vaca-Dixon Substation across Interstate 80 (I-80) and northwest of the project site, using an approximately 1.1-mile long 230-kilovolt (kV) generation tie (gen-tie) line, portions of which would be installed overhead and underground. To accommodate the interconnection of the project, PG&E would install a new 230-kV Double Bus Bay structure with associated foundations and supports on approximately 0.6 acre of the existing substation. This new bay would house four switch support structures and associated equipment for the new 230-kV connection. In addition, PG&E would also construct, own, and operate the portion of the gen-tie between the point of change of ownership pole immediately south of I-80 and the first point of interconnection at the Vaca-Dixon Substation, including five of the ten structures. The project would be unstaffed after construction, with operational control from an offsite control room through the SCADA system. Operational staff would perform periodic inspections and maintenance as necessary.
Opt-In Certification
Prior to the June 30, 2022, signing of Assembly Bill (AB) 205, the CEC’s powerplant licensing jurisdiction was limited to thermal powerplants 50 megawatts (MW) or larger. To accelerate the state’s transition to renewable energy and to maintain electrical system reliability under this transition and during extreme climate-change-driven events, AB 205, as modified by AB 209 expands the types of facilities that can be certified by the CEC. This “Opt-in” certification process is available to solar photovoltaic and terrestrial wind energy powerplants of 50 MW or more, energy storage facilities of 200 megawatt-hours (MWh) or more, the electric transmission lines from these facilities to the first point of interconnection, and facilities that manufacture or assemble clean energy or storage technologies or their components with a capital investment of at least $250 million. In addition, thermal powerplants of 50 MW or more that do not use fossil or nuclear fuels may choose the Opt-in process rather than the CEC’s Application for Certification process. AB 205 authorizes the CEC to accept applications for these facilities and provides a new, streamlined process for their review and a decision by the CEC. The CEC is the “lead agency” under the California Environmental Quality Act and is required to prepare an environmental impact report for any facility that elects to opt-in to the CEC’s jurisdiction. With exceptions, the issuance of a certificate by the CEC for an eligible facility is in lieu of any permit, certificate, or similar document required by any state, local, or regional agency, or federal agency to the extent permitted by federal law, and supersedes any applicable statute, ordinance, or regulation of any state, local, or regional agency, or federal agency to the extent permitted by federal law. The CEC’s authority under the opt-in certification program does not supersede the authority of the California State Lands Commission to require leases and receive lease revenues, if applicable, or the authority of the California Coastal Commission, the San Francisco Bay Conservation and Development Commission, the State Water Resources Control Board or applicable regional water quality control board, or, in the case of manufacturing facilities, the applicable local air quality management district or the Department of Toxic Substances Control.
