Top 10: US Battery Energy Storage Facilities
As the demand for renewable energy remains crucial, battery energy storage systems have emerged to stabilise power grids and enhance
AES just completed the first half of Bellefield, which will become the largest solar + storage facility in the US. The 1,000-megawatt (MW) Bellefield 1 project in Kern County, California, includes 500 MW of solar and 500 MW of four-hour battery storage, all under a 15-year contract with Amazon.
When the full 2,000 MW Bellefield project is done, it will be the biggest solar-plus-storage installation in the country. “Completing the first 1,000 MW of Bellefield demonstrates how rapidly solar and storage can be deployed to meet the growing energy demand of data centers,” said AES CEO Andrés Gluski.

Energy storage supports a grid increasingly defined by renewable energy. It is paired with renewable energy to balance the grid, match intermittent supply and demand, and provide reserve power for when it is needed most, among other functions. Energy storage projects across the U.S are making strides in this area, as recapped in three recent project updates by pv magazine USA.
A 131 MW energy storage facility can power approximately 130,000 homes for 4 hours. This capacity was added across two projects: the 131 MW Westside Canal project in Imperial Valley and the 40 MW Fallbrook project in northern San Diego County.
Three recent project announcements are contributing toward the rapid ramp up of energy storage in the U.S. California utility San Diego Gas & Electric has completed two energy storage facilities totaling 171 MW / 684 MWh.
