Duke Energy Renewables completes Notrees Battery Storage Project

Duke Energy Renewables, part of Duke Energy's Commercial Businesses, completed its 36-MW energy storage and power management system at its Notrees Windpower Project in west Texas. The system completed testing and became fully operational in December 2012. Xtreme Power designed and installed the 36-MW capacity Dynamic Power Resource at Notrees and will continue to operate the system. In addition to increasing the supply of renewable energy during periods of peak demand, the system will help stabilize the frequency of electricity traveling throughout the power grid. Duke Energy is working closely with the Energy Reliability Council of Texas (ERCOT) to increase frequency or absorb energy to decrease frequency.
