Duke's Plans for Battery Storage System Gain Momentum

LCG, April 15, 2011--Duke Energy Renewables will employ a $44 million dollar, 36-MW battery storage system to support its 153-MW, Notrees Wind Project located in west Texas. Duke's spokesperson stated that it will be the world?s largest power storage system for a wind farm after it is installed late next year.

Duke selected Xtreme Power, a manufacturer of large-scale developer of digital power systems, to design, install and operate the battery storage system. The project is funded in part by a $22 million grant from the U.S. Department of Energy (DOE).

The Notrees Wind Project commenced service in April 2009. The first phase of the project is rated at 90 MW and includes 55 Vestas turbines that operate at 1.65 MWs each; the second phase is rated at 60 MW and includes forty, 1.5-MW General Electric turbines.

The Duke spokesperson stated, "In addition to supplying stored renewable energy, this battery storage system will be capable of providing other key grid services, including helping smooth out the frequency of electricity traveling throughout the power grid....One of the key intents of this energy storage project is to test and demonstrate how that added flexibility can benefit renewable-power projects throughout the country."

The Electric Power Research Institute (EPRI) will support the project team and collect data to evaluate other potential grid applications.
