US utility Florida Power and Light Company (FPL) has announced that it has installed the first battery modules for the Manatee Energy Storage Center. This means the ‘world’s largest solar-powered battery storage facility’ is now 75% complete, according to FPL.

The 409MW/900MWh energy storage plant will have 50,000 battery modules once completed by the end of 2021.

FPL has installed 100 of the 132 battery containers that are planned for the project. Each container will house 400 battery modules, whilst each battery module will store energy equivalent to roughly 2,000 iPhone batteries.

Combined, the battery system will be equivalent to approximately 100 million iPhone batteries and will power 329,000 homes for more than two hours.
