ENERGY STORAGE IN CALIFORNIA
Double Butte energy storage project
AES’ Double Butte storage project is a proposed battery energy storage facility in Menifee, California that will provide a critical, cost-effective source of reliable power for the region’s electric grid.
Energy storage enables power generated during the day to be stored and delivered during periods of high demand, which helps stabilize the grid and reduce California’s reliance on fossil fuels. By delivering stored power when it is most needed, the Double Butte storage system will be critical to accelerating California’s transition to achieving 100% carbon-free energy by 2045.
500 MW, 2,000 MWh storage capacity
Enough stored energy to power 375K California homes for 4 hours
Located in Menifee, California

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.
Environmental and technical studies
The project will be reviewed under the California Environmental Quality Act. Environmental and technical studies for the project will include a Phase I Environmental Site Assessment, hydrology, geotechnical, cultural resources, land, topography, biological, wetlands, economic impact and other studies. AES will work with the relevant government and regulatory agencies to mitigate potential environmental impacts from the project.
Community impact and engagement
AES is committed to being a good neighbor and partner to the communities where our projects are located. This includes informing and engaging project stakeholders and the public throughout all phases of the project. AES also supports local contractors, community organizations and programs.
