March 11 (SeeNews) – US utility Duke Energy Corp (NYSE:DUK) is testing hybrid ultracapacitor-battery energy storage system at one of its substations in North Carolina, it said Thursday.
The 100-kW/300-kWh storage system, said to be the first of its kind, went online last month. It will be used to demonstrate applications, including extended operational life, rapid response, real-time solar smoothing and load shifting. There is a 1.2-MW solar installation connected near the substation.
“With so many solar installations in North Carolina, we must look for innovative ways to better incorporate renewable energy into our system – and still provide reliable service at a competitive price for our customers,” said Thomas Golden, technology development manager for Duke Energy.
