Duke Energy Florida to build 22 MW of electricity storage

Duke Energy Florida (DEF) announced three battery storage projects, totaling 22 megawatts, that will improve overall reliability and support critical services during power outages, according to the company.   

As the grid manager and operator, DEF can maximize the versatility of battery technology to include multiple customer and electric system benefits such as balancing energy demand, managing intermittent resources, increasing energy security and deferring traditional power grid upgrades. 

  • The 11-megawatt (MW) Trenton lithium-based battery facility will be located 30 miles west of Gainesville in Gilchrist County. The energy storage project will continue to improve power reliability using newer technologies. 
  • The 5.5-MW Cape San Blas lithium-based battery facility will be located approximately 40 miles southeast of Panama City in Gulf County. The project will provide additional power capacity to meet our customers’ increasing demand for energy. This project is an economical alternative to replacing distribution equipment necessary to accommodate local load growth. 
  • The 5.5-MW Jennings lithium-based battery facility will be located 1.5 miles south of the Florida-Georgia border in Hamilton County. The project will continue to improve power reliability through energy storage as an alternative solution to installing new and more costly distribution equipment. 

Currently the company plans to complete all three projects by the end of 2020. 

“These battery projects provide electric system benefits that will help improve local reliability for our customers and provide significant energy services to the power grid,” said Catherine Stempien, Duke Energy Florida state president. 

“Duke Energy Florida will continue to identify opportunities in battery storage technology which will deliver efficiency improvements to our customers.” 

Solar + Storage and Microgrids

As part of DEF’s commitment to renewables, the company is investing an estimated $1 billion to construct or acquire a total of 700 MW of solar power capacity and 50 MW of battery storage through 2022.
 Duke Energy is leading the industry deployment of battery technology. Last fall, the company and University of South Florida St. Petersburg unveiled a Tesla battery storage system that is connected to a 100-kilowatt (kW) solar array – the first of its kind in Florida. 

This solar-battery microgrid system manages the energy captured by the solar array, situated on top of the university’s parking garage. The solar array was constructed three years ago through a $1 million grant from Duke Energy. The microgrid provides a backup power source during a power outage for the parking garage elevator, lights and electric vehicle charging stations

In addition to expanding its battery storage technology and solar investments, DEF is investing in transportation electrification to support the growing U.S. adoption of electric vehicles (EV), 530 EV charging stations and a modernized power grid to deliver the diverse and reliable energy solutions customers want and need. 

Energy storage, solar PV and microgrids are explored in depth in Summit Sessions and Knowledge Hubs at POWERGEN International (Nov. 19-21, New Orleans) and DISTRIBUTECH International (January 28-30, 2020, San Antonio).
