Duke Energy intends to store electricity generated at its 153 MW Notrees wind project in west Texas using an energy-storage and power-management system developed by Xtreme Power.
Duke Energy is matching a $22 million grant from the U.S. Department of Energy (DOE) to install the large-scale batteries. Xtreme Power will design, install and operate a 36 MW capacity Dynamic Power Resource (DPR) system at the wind farm. This system will store excess wind energy and discharge it whenever demand for electricity is highest.
In addition to increasing the supply of renewable energy during periods of peak demand, Xtreme's DPR solution will help stabilize the frequency of electricity traveling throughout the power grid.
Duke Energy will work 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 the wind farm will be shared publicly through the DOE's Smart Grid Information Clearinghouse. Duke Energy is targeting an in-service date for the battery storage system by late 2012.
