Clearway Energy Group has commenced the construction of a solar-plus-storage project in Kern County, California, with the development expected to bring significant renewable energy capacity to the region. The Rosamond South I project, featuring a combination of solar photovoltaic (PV) panels and a battery energy storage system (BESS), will play a crucial role in enhancing the clean energy landscape in California.
Clearway’s Solar-Plus-Storage Project in California
The construction of the Rosamond South I project marks a significant milestone for Clearway Energy Group, with the company securing substantial financing for the development. The project will consist of 140MW of solar PV capacity paired with a 118MW battery energy storage system, contributing to Clearway’s extensive renewable energy portfolio in Kern County.
Expected to be operational by 2025, the project will leverage cutting-edge technologies to deliver reliable and sustainable energy to the local grid. McCarthy Building Companies, the engineering, procurement, and construction contractor for the project, is overseeing the construction process to ensure the timely completion of the solar-plus-storage facility.
Long-Term Power Purchase Agreements and Impact
Clearway has secured long-term power purchase agreements (PPAs) with several key entities in California, including MCE, the University of California, Rancho Cucamonga Municipal Utility, Eastside Power Authority, and the city of Moreno Valley. These agreements underscore the commitment of various stakeholders to advancing renewable energy deployment and reducing carbon emissions in the state.
With the Rosamond South I project, Clearway is not only expanding its renewable energy footprint but also contributing to the state’s ambitious clean energy goals. By integrating solar PV with energy storage, the project will enable grid stability, enhance energy resiliency, and support the transition to a more sustainable energy future in California.
Conclusion
The commencement of construction on Clearway’s solar-plus-storage project in Kern County represents a significant step forward in the transition to clean energy in California. By combining solar PV with a battery energy storage system, the project will deliver renewable energy capacity, support grid reliability, and contribute to the state’s decarbonization efforts. Clearway’s commitment to sustainable energy development underscores the importance of innovative solutions in addressing climate change and building a cleaner, more resilient energy infrastructure.
