Duke Energy to Deploy Energy Storage Technology at Texas Wind Farm
CHARLOTTE, N.C., April 14, 2011 /PRNewswire/—Duke Energy (NYSE: DUK) intends to store electricity generated at its Notrees Windpower Project in west Texas using an energy storage and power management system developed by Austin-based Xtreme Power.
In November 2009, Duke Energy announced plans to match a $22 million grant from the U.S. Department of Energy (DOE) to install large-scale batteries capable of storing electricity produced by the company’s 153-megawatt (MW) Notrees wind farm, located in Ector and Winkler counties. After due diligence, Duke Energy chose Xtreme Power (www.xtremepower.com) to design, install and operate a 36 MW-capacity Dynamic Power Resource™ system at the wind farm. When complete, the battery storage system will be one of the largest of its kind in the world.
This system will store excess wind energy and discharge it whenever demand for electricity is highest – not just when wind turbine blades are turning. In addition to increasing the supply of renewable energy during periods of peak demand, Xtreme’s Dynamic Power Resource™ solution will help stabilize the frequency of electricity traveling throughout the power grid.
Duke Energy will work closely with the Energy Reliability Council of Texas (ERCOT) to integrate the wind power and battery storage solution into the state’s independent power grid. The Electric Power Research Institute (EPRI) will advise the project team, collect data and help assess the potential for broader adoption of energy storage solutions throughout the industry. Results from the storage project at Duke Energy’s Notrees wind farm will be shared publically through the DOE’s Smart Grid Information Clearinghouse.
