June 13, 2019: Duke Energy Florida, a subsidiary of Duke Energy Corporation, announced plans on June 3 to install three battery storage projects totalling 22MW in Florida to improve the state’s power reliability and provide backup generation during power outages.
The power utility will use the systems to balance energy demand, manage intermittent renewable generation, increase security-of-supply and defer power grid upgrades.
The biggest of the systems is the 11MW Trenton lithium battery in Gilchrist County. The two others will both be 5.5MW lithium projects — one located in Gulf County, the other in Hamilton County.
All three projects are to be completed by the end of 2020.
DEF aims to invest around $1 billion to construct or acquire a total of 700MW of solar power facilities and 50MW of battery storage through 2022.
Last month ESJ revealed the North Carolina Utilities Commission had approved plans by Duke Energy to build a 2MW solar and 4MW lithium ion battery microgrid system to prevent black outs in western North Carolina.
Last October Duke Energy revealed plans to deploy 300MW of energy storage and microgrid capacity across the Carolinas in the next 15 years.
