New England Solar Cost-Reduction Partnership: Accomplishments, Lessons Learned, and Recommendations

October 28, 2016

In 2013, five New England states — Connecticut, Massachusetts, New Hampshire, Rhode Island, and Vermont, with support and coordination from Clean Energy States Alliance (CESA), — forged the New England Solar Cost-Reduction Partnership to help drive down regional solar soft costs and enable scaled deployment of rooftop solar. Over the past three years, the Partnership tackled a wide range of "soft cost" barriers to PV deployment, including: difficult, costly, and slow permitting and interconnection processes in some locations; the need for new financing tools and cost-efficient group purchasing arrangements; and unfavorable zoning rules for solar in some jurisdictions. This report offers the public insights about project accomplishments, successes, lessons learned, and recommendations for future actions.

The New England Solar Cost-Reduction Partnership is supported by a grant from the U.S. Department of Energy SunShot Initiative Rooftop Solar Challenge II program. The SunShot Initiative is a collaborative national effort that aggressively drives innovation to make solar energy fully cost-competitive with traditional energy sources before the end of the decade. Through SunShot, the Energy Department supports efforts by private companies, universities, and national energy laboratories to drive down the cost of solar electricity to $0.06 per kilowatt-hour.
