World's largest solar-powered battery system becomes operational in USA

Florida Power and Light Company (FPL) has announced that the 409 MW/900 MWh Manatee Energy Storage Center is fully commissioned.

The newly operational battery located in Florida is the world’s largest battery when measured by generating output and the world’s largest solar-powered battery when measured by both total output and capacity per hour. The battery has enough capacity to power approximately 329,000 homes for more than two hours and is equivalent to 100 million iPhone batteries.

Charged by the existing Manatee Solar Energy Center, the battery will increase the predictability of solar – extending its benefits even when the sun is not shining, such as at night or on a cloudy day. The battery system will store extra solar energy produced by the existing Manatee Solar Energy Center and feed that power to the grid when it’s needed most. 

The Manatee Energy Storage Center is made up of 132 energy storage containers, organized across a 40-acre plot of land, equivalent to 30 football fields.
