Battery Energy Storage in California
Jewelflower
AES’s Jewelflower project is a planned battery energy storage project that will help build a secure and sustainable energy future in San Jose, California. By storing excess energy for when it is needed most, Jewelflower provides flexibility that will be critical to deliver reliable, affordable power to meet California’s increasing energy demand.
As a company dedicated to developing and delivering innovative energy solutions with long-term impact, our projects create jobs, build community partnerships, generate revenue for local governments and schools, and protect the environment.
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 12 long-term operations and maintenance jobs
Project details
- Containerized lithium-ion battery energy storage
- Sited on approximately 40 acres of privately owned land
