The Mars Hill Wind Farm is situated on a partially developed ridgeline in Mars Hill, Maine.  The wind farm consists of 28 wind turbines, 4 miles of new and upgraded existing roads, 4 miles of underground 35 KV power collection lines, .9 miles of overhead 35 KV power collection lines, a substation, delivery lines and a switching station.

Sargent Corporation was contracted to clear 75 acres and construct the 30’ wide access roads, 260’ diameter tower pads, the substation and switching station site work and pads, as well as the excavation and backfilling for the underground collection lines and tower foundations.
