The Iowa Stored Energy Park Agency (ISEPA) has chosen a reservoir west of Dallas Center in central Iowa (30 miles outside Des Moines) for a compressed air energy storage (CAES) facility, according to a statement released by the Iowa Association of Municipal Utilities (IAMU), the project's primary supporter.
According to IAMU, the facility, called the Iowa Stored Energy Park (ISEP), will use air that has been stored underground to generate energy when it is needed by utilities. In addition, energy derived from wind power in Iowa will drive compressors that push the air underground. ISEP is expected to provide 268 MW of CAES generating power and use approximately 75 MW of wind power.
The U.S. Department of Energy and Sandia National Laboratories have provided $2.9 million in funding and technical support for the project.
‘Construction is to be completed by May 2011, with commercial operation to begin about July of 2011,’ says John Bilsten, vice president of ISEPA and general manager of Algona Municipal Utilities.
