Duke Energy has deployed a wind energy storage demonstration system at the 153 MW Notrees Wind power project in western Texas. The project demonstrates how energy storage and power storage technologies can help wind power systems address intermittency issues by building a 36 megawatt (MW) turnkey energy storage and power management system capable of optimizing the delivery of energy, in addition to providing regulation service in the ERCOT market. The project is supported by a U.S. DOE Office of Electricity ARRA grant.
