Utilities plan Iowa project to store wind-generated power

MINNEAPOLIS (AP) - A group of utilities in Iowa, Minnesota and the Dakotas plan to spend $200 million on a project in Iowa that would store energy generated by wind turbines. The Iowa Stored Energy Park would essentially act as a "battery" for wind energy, said Bob Haub, executive director of the Iowa Association of Municipal Utilities. Wind farms in Iowa, Minnesota and the Dakotas would ship energy over the power grid to the storage park near Des Moines. Xcel Energy and the federal government are experimenting with ways to "store" wind power in the form of hydrogen, but the Iowa project would employ a far simpler strategy that would include the following steps:

New blade might help expand wind power

Knight & Carver will make conventional turbine blades at first. But earlier this month, it made a single curved blade designed to tap into low-speed winds not captured with current technology. South Dakota is one of the windiest places in the nation, yet it trails neighboring states in developing wind energy. The new facility is part of an effort to find a niche in the emerging industry while bringing technology jobs to rural areas.
