First Wind Holdings Inc., the renewable-energy developer being acquired by SunEdison Inc. (SUNE), received approval to sell power from five proposed solar projects in Idaho. The projects in southern Idaho’s Ada, Elmore, Owyhee and Power counties are expected to be complete in 2016, Boston-based First Wind said today in a statement. They will have 20 megawatts of capacity each and have 20-year contracts to deliver electricity to Idaho Power Co.
