The Massachusetts Department of Public Utilities (DPU) has approved deals for NStar to buy power from three wind farms, the Boston Globe reports. Contracts between NStar and Hoosac Wind in Massachusetts, Groton Wind in New Hampshire and Blue Sky East in Maine were approved.
Utilities in Massachusetts must obtain 3% of their power through long-term contracts with renewable energy providers. The NStar deals represent about 1.6% of the utility's demand.
The approximately 29 MW Hoosac project is expected to be operational in July 2012, followed by the 32 MW Blue Sky East in May 2012 and the 48 MW Groton project in December 2012.
Iberdrola owns the Hoosac and Groton projects, and First Wind owns the Blue Sky project.
