Clay and Milk: Iowa State University and Alliant Energy will collaborate on a solar farm to be established on university land south of Ames. The Iowa Board of Regents has approved a request from Iowa State to proceed with the development of the solar farm and to enter into a lease agreement with Alliant Energy. Alliant Energy will design, construct, own, operate and maintain the solar farm. The up to 900-kilowatt solar farm, at maximum output, could power 230 homes annually and will provide an equal amount of electricity to nearby teaching and research farms, Alliant Energy said in a release. Iowa State will receive renewable energy credits generated by the solar farm, which will offset a portion of the university’s annual carbon emissions.
