Utility Will Use Batteries to Store Wind Power - New York Times

Costly, but creative thinking. Storage is essential to make wind a viable contributor to base load power demands. This battery technology is a start, particularly for peak demand contribution to the grid.

However, the wind seldom blows much at night, except in a storm, at least in this neck of the woods.

"American Electric Power’s batteries will be used to smooth the power delivery from wind turbines. They can charge at night, when the wind is strong but prices are low, and give the electricity back the next afternoon, when there is hardly any wind but power prices are many times higher, company officials said. That strategy would reduce the amount of power generated from inefficient peak-demand units."
