Energy Storage in California
Luna and LAB energy storage
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.

Our clean energy commitment
AES’ Luna Storage and LAB are energy storage projects located in California. We are committed to responsible clean energy development that creates long-term value and positive impact for both the environment and local communities.

Economic and environmental benefits
We believe in being a good neighbor, ensuring responsible clean energy development that benefits both the environment and local communities without burdening existing infrastructure.
Project details
Luna Storage and LAB are standalone lithium-ion battery storage projects in Lancaster, Los Angeles County, California. These projects store clean energy for use during periods of high demand or when solar and wind power are unavailable.
- Serving Clean Power Alliance, PG&E and their customers
- Luna and LAB were designed to provide essential and flexible power resources to California's grid.
- They played a critical role in supporting the grid during the early September 2022 heatwave.
- The flexibility of these battery storage assets is vital for accelerating California's clean energy transition.
- These projects contribute to California's goal of achieving 100% carbon-free energy by 2045.

Sustainability Resources
Sustainability best practices
At AES, safety is our highest priority, and we’ve focused on improving lives for more than 40 years. As a leading innovator in energy solutions, sustainability is core to both our strategy and our culture. We are committed to responsible land use and incorporating sustainable best practices into the entire project lifecycle, contributing to building a domestic circular renewables economy and reducing foreign dependence.
Stored clean energy from local resources
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.
Local partnerships
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.
