Battery Energy Storage in California
Jewelflower
UPDATE
After careful consideration, AES has decided not to move forward with the proposed Jewelflower Battery Energy Storage project. No permit application had been submitted for the project.
As with every project in early development, we evaluated a range of factors, including project economics, infrastructure requirements, market conditions, community considerations, and long-term investment priorities.
Over the past several months, we have held valuable conversations with landowners, local officials and organizations, and other community stakeholders. We are grateful to everyone who took the time to learn about the project and share their perspectives.
While the Jewelflower project will not move forward, battery energy storage continues to be a critical part of AES' development portfolio and strategy, and an important part of California's energy future. By storing power and delivering it when it is most needed, energy storage will provide much needed resiliency and flexibility to the power grid. We remain committed to advancing projects throughout the state that provide the safe, reliable, and affordable power essential to strengthening local grid reliability and creating meaningful benefits for communities.

350 MW battery energy storage planned capacity
Enough stored energy to power the equivalent of more than 262,500 homes for four hours
Located in
San Jose, California
Our clean energy commitment
We believe in being a good neighbor, ensuring responsible clean energy development that creates long-term value and positive impact for both the environment and local communities without burdening existing infrastructure.
Economic and environmental benefits
The project is expected to generate substantial economic and environmental benefits for local communities and the region.
$193 million
Economic activity expected to be generated over the project’s life
$156 million
Expected to be generated in tax revenue for San Jose, Santa Clara County, and local schools over the project’s lifetime
112 jobs
Expected to be created annually during peak construction, plus an estimated 9 long-term operations and maintenance jobs
Project details
- Containerized lithium-ion battery energy storage
- Sited on approximately 40 acres of privately owned land
- AES will be the long-term owner and operator of the facility
- At the end of the project's life, a decommissioning plan allows for the land to return to agricultural use or other uses consistent with land-use policies at the time
