During the testing, the firm will demonstrate multiple service applications including extended operational life, rapid response, real-time solar smoothing and load shifting of the new battery and ultracapacitor system.

The HESS system features Aquion’s 100kW/ 300Kwh battery technology and Maxwell-built fast-response ultracapacitors (UCAPs) to help manage solar smoothing events in real-time.

Additional features include a Win Inertia-developed hybrid energy storage system (SHAD), designed to allow seamless operation of Aquion’s batteries and Maxwell’s UCAPs in the same energy solution.

The hybrid energy storage system is designed to help integrate energy storage technology in a bid to provide simultaneous and cost effective grid services.

Duke Energy technology development manager Thomas Golden said: "This approach will allow our energy storage systems to do a variety of tasks.

"The demonstration of new technologies will help facilitate wider adoption across the nation," said Matt Roberts, executive director of the Washington, D.C.-based Energy Storage Association.

"Duke Energy is to be commended for its work on this project and partnership efforts in advancing energy storage solutions."
