First Wind finalized seven 20-year PPAs with Rocky Mountain Power, a division of PacifiCorp. As part of the purchase agreements, Rocky Mountain Power will buy the output of the planned 20-MW Seven Sisters projects under its obligation from the federal Public Utility Regulatory Policies Act, or PURPA. The Seven Sisters portfolio includes seven separate solar photovoltaic projects, four of which are to be sited in Beaver County and three to be located in Iron County, Utah. The start of major construction is slated to begin in late 2014 with a target completion date of July 2015. The projects will use more than 73,000, 300-watt solar panels.
