    Luna and LAB Energy Storage

    Flexible, reliable clean energy for California

    Energy storage is the bridge between a resilient power grid and our clean energy future. Now fully operational, AES’ Luna and Lancaster Area Battery (LAB) energy storage facilities are helping California achieve both objectives.

    About the Luna-LAB energy storage facilities


    Combined 227 MW, 908 MWh of clean energy storage capacity

    Enough stored clean energy to power 170,000 California homes for 4 hours

    Serving Clean Power Alliance, PG&E and their customers


    Adds flexible and clean energy resources to manage peak loads, grid reliability

    Luna Storage and LAB are standalone, lithium-ion battery storage projects located in the City of Lancaster, in Los Angeles County, California. Their ability to store clean energy for use during periods of high demand, and when the sun is not shining or the wind is not blowing, is critical to California’s clean energy transition. The Luna and LAB battery storage facilities were built exactly for this purpose and provided essential and flexible power resources to the California grid during the early September 2022 heatwave. The flexibility these assets provide is critical to accelerating California’s transition to meet the state’s commitment to achieving 100% carbon-free energy by 2045.

    Stored clean energy from local resources

    Luna LAB

    Luna Storage and LAB store and deliver clean energy from 18 AES solar facilities in the area, which enables better utilization of renewable generation. Battery storage provides a critical and cost-effective source of clean and reliable power that can be stored and used at night or during periods of high demand, which helps reduce California’s reliance on fossil fuels.

    Power generated and stored in the battery storage facilities is delivered to the electric grid via a connection to the Big Sky Substation. Clean Power Alliance is contracted to purchase power from Luna Storage and Pacific Gas & Electric (PG&E) is contracted to purchase capacity from the LAB.

    Supporting Our Communities

    As with all AES’ clean energy projects, we are committed to being a good neighbor, partnering with landowners and investing in local communities. The AES team works with a broad cross section of government, community, business, labor unions, and other stakeholders in the California communities we serve to support high-impact initiatives and programs.

    For example, AES contributes to workforce development through an ongoing partnership with Antelope Valley College, a public community college in Lancaster, California. AES provides annual scholarship funding for students in STEM and vocational training.
