In November 2009, Duke Energy planned to match a $22m grant from the US Department of Energy (DOE) to install large-scale batteries capable of storing electricity produced by the company’s 153MW Notrees wind farm, located in Ector and Winkler counties.

After due diligence, Duke Energy chose Austin-based Xtreme Power to design, install and operate a 36MW capacity Dynamic Power Resource system at the facility.

Duke Energy will collaborate with the Energy Reliability Council of Texas to integrate the wind power and battery storage solution into the state’s independent power grid.

The Electric Power Research Institute 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 Notrees plant will be shared publically through the DOE’s Smart Grid Information Clearinghouse.

Duke Energy said it is targeting an in-service date for the battery storage system by late 2012.
