FPL installs 10MW energy storage system at solar plant in Florida

CTBR Staff Writer Published 12 March 2018

Florida Power & Light (FPL) has installed a 10MW/40MWh battery energy storage system at one of its solar plants in the state.

The battery storage system will store the energy generated from the 74.5MW Babcock Ranch Solar Energy Center during the day. The stored energy will be delivered to the grid to supplement dips in the plant’s operations. 

FPL and other NextEra Energy companies are researching and testing battery storage technologies to study their potential benefits. Presently, NextEra Energy companies operate a total of about 140MW in batteries with more than 150MWh of storage capacity.

Last month, the company announced a larger-scale application of ‘DC-coupled’ batteries at a solar plant in the country, which is 4MW/16MWh storage system at its Citrus Solar Energy Center in DeSoto County in the state.

In 2016, FPL commissioned several battery-storage pilot projects to test different applications in real-world operating conditions. Systems are presently being tested at Everglades National Park's Flamingo Visitor Center, the Crandon Tennis Center on the island of Key Biscayne along with other locations in south Florida. 

Currently, FPL operates 14 solar power plants across Florida.

Recently, FPL announced that it will construct four new solar plants in the state and has selected the locations for those plants.

These four new solar plants will include Interstate Solar Energy Center located in St. Lucie County, Miami-Dade Solar Energy Center in Miami-Dade County, Pioneer Trail Solar Energy Center in Volusia County and Sunshine Gateway Solar Energy Center in Columbia County.

Each of the solar plants will have a capacity of 74.5MW. The four facilities can generate enough clean electricity to be supplied to about 60,000 homes and during the operational life of the projects, the solar plants are claimed to save as much as $40m for FPL’s customers.
