SOLAR + STORAGE IN CALIFORNIA

Bellefield solar + storage

under construction

AES’ Bellefield project is a solar + storage facility in Kern County, California. The project represents a significant step in accelerating California's commitment to achieving 100% carbon-free energy by 2045.

Enough clean energy to power the equivalent of 467,000 homes annually

Located in California City and Mojave, Kern County

Our clean energy commitment

AES’ Bellefield solar + storage project is a planned facility 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 are committed to responsible, low-carbon energy development that creates long-term value and benefits for the environment and local communities.

$ 150 million in tax revenue

expected to be generated to the community and county over the life of the project.

1,000 union jobs

Expected to be created during peak construction, while supporting indirect employment and businesses in the area.

Project details

The Bellefield solar + storage project serves as a model for future projects across California, demonstrating how such projects can integrate seamlessly into the local economy while providing affordable clean energy. In addition to powering homes and businesses, the Bellefield project will also help strengthen the energy grid and ensure a sustainable, reliable energy supply during peak demand periods.

Built in two two phases, each phase will include 500 MW of solar plus 500 MW of four-hour duration battery energy storage
14-mile transmission line will connect the project to the Southern California Edison (SCE) Windhub Substation
Located on about 7,500 acres of privately owned land
AES will serve as the long-term owner and operator of the facility
Maximo robots will be used for solar module installation

Accelerating solar installation through innovation

To accelerate Bellefield's construction and ensure system reliability, Maximo, an AI-enabled robotic system developed by AES is assisting construction crews, improving the safety, speed, and accuracy of solar module installation.
