According to FPL, the battery will help reduce customer costs, and will also be good for the environment.
It will store energy from the grid during times of lower demand, reducing the need for additional power plants to come online during peak hours.
The Wynwood Battery has 10 megawatts of capacity, according to FPL documents.
FPL is also building a much larger battery in Manatee County, with 409 megawatts of capacity. It will be charged by a solar plant there that is already complete. Completion of the Manatee battery is expected in late 2021.
