The project's 36-megawatt (MW) advanced lead acid battery helps
smooth the naturally variable output from Duke Energy's 153-MW
Notrees Wind Power Project. By storing energy generated by the wind
farm, the project can respond quickly to regulate frequency and
provide ancillary services for grid management.
"Incorporating energy storage will make the electric industry
more efficient," said Jeff Gates,
managing director in Duke Energy's Commercial Transmission
business, and lead developer on the project. "This project has
proven the technology can be deployed at commercial scale – and the
flexibility and speed of response has provided tremendous benefit
to the grid operator."
The project has been operating since late 2012. Duke Energy
matched a $22 million Department of
Energy grant to develop the project, and Texas-based Xtreme Power designed and
installed the battery.
Award winners were judged on services provided to the grid,
financing options, ownership model and technology
strengths.
"The Notrees project is a success story at taking
forward-thinking innovation and creating business value," said
David Mohler, vice president,
Emerging Technology at Duke Energy. "It shows that energy storage,
as part of the ecosystem for delivering electricity, has an
exciting future."
