Grant being negotiated for Large scale batteries

Exciting news on the way regarding large-scale batteries.
As always Duke Energy is on the cutting edge of this experiment!24 November 2009-- Duke Energy said it would match a $22 million grant from the U.S. Department of Energy to design, build and install large-scale batteries to store wind energy at one of its wind farms in Texas. The 20 MW storage project at
the Notrees Windpower Project is valued at $43.6 million.
Batteries at the wind farm will store excess wind energy and discharge it when demand is high. The 95 wind turbines at Notrees have a capacity of 151 MW.

Duke Energy and DOE must negotiate terms of the grant before any funds are released. The Electric Power Research Institute will advise Duke Energy on the project.
