First Wind, a Boston-based renewable energy company, yesterday held a groundbreaking ceremony for its 14 megawatt solar project in Warren.

Located at three sites in the town of Warren, the solar project will be the second-largest in Massachusetts. It is also one of First Wind’s first renewable energy projects in its home state and one of its first solar developments. The company also has a 3 MW (AC) project in Millbury.

Construction on the Warren and Millbury solar projects is being led by Borrego Solar Systems, a designer and installer of commercial and utility solar power systems. Construction on all four project sites should be completed and operating by June 2014. Construction activities will create roughly 85 construction-related jobs.

First Wind broke ground after securing financing and finalizing a 30-year power purchase agreement with the University of Massachusetts (UMass), with the majority of the power generated being delivered to the Lowell and Medical Center campuses. Through these solar projects, UMass will is estimated to save more than $1 million in annual energy costs, or a total of $30 million over the course of the 30-year agreement.
