DANFORTH, Maine — A 17-unit expansion of the Stetson Wind project in eastern Maine is complete.

A ribbon-cutting for First Wind’s project is scheduled for Tuesday. First Wind officials will be joined by local community and business leaders at the project site near Danforth to mark the beginning of commercial operations for the Stetson expansion. Construction started in November 2009.

The first phase of the project, which includes 38 turbines on Stetson Mountain, was completed in January 2009. Together, the two Stetson projects will produce 82.5 megawatts of power.
