FPL Unveils New Energy Storage System
March 2018

​In February, Florida Power & Light (FPL) unveiled a new, cutting-edge solar-plus-storage system that fully integrates battery technology with a universal solar energy center in a way that increases the plant's overall energy output. It is believed to be the first of its kind in the country.

By incorporating this new technology into the FPL Citrus Solar Energy Center, FPL expects to increase the amount of solar energy that the plant can provide to the energy grid by more than half a million kilowatt-hours per year.

The FPL Citrus Solar Energy Center is one of three solar power plants FPL operates in Florida's DeSoto County – a community that boasts more solar panels than residents. In addition to the FPL Citrus Solar Energy Center, DeSoto County is home to Florida's first solar power plant, the 25-megawatt FPL DeSoto Next Generation Clean Energy Center, which was built in 2009, and the 74.5-megawatt FPL Wildflower Solar Energy Center, which entered service on Jan. 1, 2018.

"Every day, we work on new ways to better serve our customers with technology innovations and efficiency improvements,” said Eric Silagy, president and CEO of FPL. "By harnessing more solar energy from the same power plant, this has the potential to further reduce our fossil fuel consumption and save our customers even more money on their electric bills."

The new system at FPL Citrus Solar Energy Center features a 4,000-kilowatt storage capacity comprised of multiple integrated batteries. The system also has the ability to store the energy and dispatch it to the energy grid at a later time.

This technology has the potential to harness millions of kilowatt-hours of solar energy a year that normally would be lost and to improve the predictability of solar energy, which naturally fluctuates with the sun's availability. Increased predictability enables FPL to dispatch other power plants more efficiently while helping customers save on costs.

This is another example of electric companies producing cleaner energy with new technologies while also benefiting customers.
