Project Description

Prairie Song Reliability Project, LLC (applicant), proposes to construct, own, and operate the Prairie Song Reliability Project (project). The project is a 1,150-megawatt (MW), approximately 9,200-megawatt hour (MWh), battery energy storage system that would be constructed on privately owned land in the Antelope Valley of northern Los Angeles County. The energy storage project includes the containerized battery energy storage system with individualized fire prevention systems, a project substation, inverters, and related facilities, such as fencing, operations and maintenance buildings, stormwater retention and infiltration basins, and communication systems. The project would connect to the existing Southern California Edison (SCE) Vincent Substation via either a 1.1-mile or a 1.8-mile generation intertie (gen-tie) line route, installed overhead using monopoles and steel lattice towers. No off-site network upgrades are required for the project to provide full capacity to the California Independent System Operation.

The project would store electricity from the power grid, providing additional capacity to the electrical grid to assist with serving load during periods of peak demand by charging when demand is low and discharging when demand is high. The project would also serve as an additional local/regional capacity resource that would enhance grid reliability, particularly to the Los Angeles Basin local reliability area, and may allow for the deferral or avoidance of regional transmission facilities.

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.
