Major US utility Florida Power & Light Company (FPL) is planning to build the world’s largest battery energy storage system adjacent to an existing solar power plant, with plans to roll out multiple other storage systems across the state.

With the key proposed battery standing at 409MW capacity, the Florida energy company claims it will be four times larger than the largest battery currently operating worldwide. Furthermore, the system will help reduce fossil fuel usage and thereby accelerate the decommissioning of two neighbouring, 1970s-era natural gas power units.

The FPL Manatee Energy Storage Center will be powered by an existing PV plant in Parrish, Manatee County, and capable of distributing 900MWh of electricity. It will start serving customers in 2021, with the batteries being used particularly during peak demand periods, thereby reducing the requirement for electricity from other power plants.
