The Goodhue wind project, where 48 turbines were going to be built, had been seeking state approval since 2008.
The application had divided local opinion over turbine setback distances, road-use agreements, wildlife protection, permitting issues and disputed contracts.
New Era also withdrew its request for approval of an avian and bat protection plan and requested the Commission terminate its site permit, which was granted in August 2011.
Last year billionaire Texas oil tycoon T Boone Pickens sold his share in the Minnesota project, previously called Goodhue, to New Era’s chief manager, Peter Mastic.
Mastic was CEO of National Wind, which co-developed Goodhue. Mastic left National Wind in July 2012, prior to its takeover by Indian-owned Trishe Wind.
New Era’s two power purchase agreements with Xcel Energy had been voluntary terminated by the Minneapolis-based utility supplier with the Commission earlier this year.
