Sequoia Energy Storage 1, LLC (applicant), a subsidiary of New Leaf Energy, Inc., proposes to construct, operate, and maintain the proposed Seahawk Battery Energy Storage System (BESS) (project). The project is a proposed 200-megawatt (MW), 800 MW-hour, BESS facility in unincorporated Santa Cruz County approximately one mile north of the City of Watsonville and east of the intersection of Minto Road and Green Valley Road. Primary components of the project include lithium-iron phosphate (LFP), or similar batteries, inverters and transformers, an on-site collector substation, an operations and maintenance building, a fire protection system, and associated site, access improvements, and construction laydown areas. The project would connect to the adjacent existing Pacific Gas and Electric Company (PG&E) Green Valley Substation via a proposed approximately 0.2-mile, 115-kilovolt generation interconnection (gen-tie) line; underground connections would include fiber optic telecommunication lines.
The proposed project would provide a service to the regional electric grid by receiving energy (charging) from the PG&E electric transmission system, storing energy on site, and then later delivering energy (discharging) back to the PG&E Green Valley Substation. The project would accommodate the integration of additional intermittent renewable energy sources.
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.
