Spruce Mountain is located in central Maine, on the banks of the Androscoggin River. The Spruce Mountain Wind Project is a 20 megawatt, 10-turbine wind project located in Woodstock, Maine. The project was built over the course of 6 months and provided jobs for about 150 workers. Spruce Mountain Wind became operational in December 2011.

Spruce Mountain Wind's 10 Gamesa G90 2-MW wind turbines produce over 60 million kilowatt-hours (kWh) of emission-free electricity each year. That is enough to power about 9,600 homes (based on 500 kWh per home per month) and reduces the amount of CO2 emissions by the equivalent of almost 3 million gallons of gasoline consumed.


PROJECT HIGHLIGHTS

  • The project was built over the course of 6 months and provided jobs for about 150 workers.
  • Site work, which was performed in under 3 months, included cutting / clearing 51 acres of trees to build the 7,300 linear feet of 24-foot-wide access road and 13,500 LF of 32’-wide crane / turbine roads.
  • The team also cleared ten acres to provide a 1-acre pad for each turbine.
  • Ten 24-foot diameter x 6-feet deep turbine foundations were completed in one month and included 18 3-inch diameter / 42-foot length rock anchors/foundation; 144 turbine anchor bolts/foundation; and 100 cubic yards of concrete/ foundation.
  • The electrical / collector system, which was completed in 3 months, included 4.1 miles of overhead 34.5-kv transmission line, 13,500 feet of 34.5-kv underground line, and 7,500 feet of single-phase overhead line to feed the project’s O&M building.
  • All turbine components were US-sourced.
  • Installation (both erection and mechanical / electrical) was completed in 2.5 months, using three cranes for the turbine erection.
