Prairie Song Reliability Project

Prairie Song Reliability Project

The applicant proposes to construct, own, and operate a 1,150-megawatt (MW), approximately 9,200-megawatt hour (MWh), BESS. The energy storage project includes the containerized BESS with individualized fire prevention systems, a project substation, inverters, and other appurtenant 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 Vincent Substation via either a 1.1-mile or a 1.8-mile generation intertie line, installed overhead using monopoles and steel lattice towers. The project would store electricity from the power grid, providing additional capacity to the electrical grid to assist with serving electrical load during periods of peak demand by charging the batteries when demand is low and discharging them when demand is high. The project would also serve as an additional local/regional energy 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.
