IPP Clearway Energy Group has closed US$550 million in financing for a solar-plus-storage project with a 118MW BESS in Kern County, California.

Construction of the Rosamond South I project—located in Kern County—has already started, which will pair 140MW of PV with a 118MW battery energy storage system (BESS). It is expected to reach commercial operations in 2025 and will bring the developer’s portfolio in Kern County to over 1.5GW of solar PV, wind and energy storage.

Engineering, procurement and construction (EPC) contractor McCarthy Building Companies is completing the construction of the project.

The project has secured long-term power purchase agreements (PPAs) with several California load-serving entities such as MCE, the University of California, Rancho Cucamonga Municipal Utility, Eastside Power Authority and the city of Moreno Valley.
