About
The Oberon II Solar Project is a 375 MW hybrid solar and battery energy storage system (BESS) located in Riverside County, California. The plant, which began operating in 2023, is owned and operated by IP Oberon II, LLC. It utilizes solar photovoltaic technology with single-axis tracking. The BESS component has a storage capacity of 500 MWh, with a duration of 4 hours, and employs lithium-ion battery chemistry (LIB). Oberon II operates within the California Independent System Operator (CAISO) balancing authority and the Western Electricity Coordinating Council (WECC) region.
The facility consists of two generators and achieved a latest annual generation of 589,752 MWh, resulting in a capacity factor of 17.9%. Oberon II is ranked as the 20th largest solar facility out of 112 in California and 111th out of 514 nationally. Financial data is available for the plant, sourced from Lawrence Berkeley National Laboratory (LBNL) solar data.
