Duke Energy Renewables, a unit of Duke Energy (NYSE: DUK), completed its 36 MW energy storage and power management system at its 153 MW Notrees Windpower Project in Texas. The system completed testing and became fully operational in December 2012.
Austin-based Xtreme Power designed and installed the Dynamic Power Resource and will operate the system. The battery storage system will help ease the variability of the wind farm, storing the excess power and discharging it whenever demand is high. The Energy Reliability Council of Texas (ERCOT) will signal to the system when to dispatch the stored energy or absorb it.
In late 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 Notrees wind farm.
The Electric Power Research Institute (EPRI) will collect performance data from the battery storage system and help assess the potential for broader adoption of energy storage solutions throughout the industry. Results from the storage project at Notrees wind farm will be shared publically through the DOE’s Smart Grid Information Clearinghouse.
