World’s Largest Solar-Powered Battery Is Now 75% Complete

The battery system will be equivalent to 100 million iPhone batteries!

The Manatee Energy Storage Center – the world’s largest solar-powered battery storage facility – is now 75% finished with 100 of 132 total containers already installed, reveals a press release from Florida Power and Light Company (FPL). The battery is housed in Manatee County as the name indicates and is expected to be fully operational by the end of the year.

When completed, the system will have a 409-MW capacity with the ability to deliver 900 MWh of energy. This is enough electricity to power 329,000 homes for more than two hours.

“With one milestone after another, FPL is following through on its steadfast commitment to make Florida a leader in sustainability and resiliency as we consistently deliver America’s best energy value – electricity that’s not just clean and reliable, but also affordable,” said FPL President and CEO Eric Silagy.

The battery will serve to replace FPL's coal plants.

“In June, we said goodbye to coal by dismantling FPL’s last coal plant in Florida just as we surpassed 40% of the way toward completing our ’30-by-30’ plan to install 30 million solar panels by 2030. Soon, the world’s largest solar-powered battery will begin serving customers, and we’ll turn our attention to an innovative green hydrogen pilot project – which could unlock the potential for a 100% carbon-free energy future," added Silagy.

The battery will store energy in order to bring electricity to homes even when the sun’s not shining (at night and on cloudy days) meaning other more polluting power sources will not be required. Although customers are bound to see some financial benefits the main gains will be environmental.

According to FPL, each battery module is capable of storing an amount of solar energy equivalent to roughly 2,000 iPhone batteries. The complete battery system will be equivalent to 100 million iPhone batteries and the energy storage containers will be organized across a 40-acre plot of land (the equivalent of 30 football fields). The battery will have a lifespan of 40 years.

“With more than 12 million solar panels installed and more than 40 solar energy centers in operation, FPL is building on its rapid solar expansion with the world’s largest solar-powered battery,” said FPL Vice President of Development Matt Valle, who delivered today’s construction update.

“But that’s just the tip of the iceberg. FPL is implementing innovative battery storage projects across the state, transforming Florida’s transportation landscape with more than 1,000 EV chargers and partnering with universities and municipalities on battery systems that leverage cutting-edge microgrid technology.”
