Maineís four First Wind industrial wind sites generated about 27 to 37 percent of their capacity in 2011 ó and thereby performed within wind industry standards for projects of their size, a company spokesman said Saturday
According to the figures Lamontagne released, the 57-megawatt Stetson I facility generated about 154,000 megawatts in 2011, or about 421 megawatts per 24-hour day. First Windís Mars Hill site generated about 127,500 megawatts of electricity, or an average of 349 megawatts per day. The Stetson II site produced 59,700 megawatts.
Full-year figures for the largest single First Wind site in Maine, the 60-megawatt Rollins Mountain project on ridgelines in Burlington, Lee, Lincoln and Winn, are not yet available. The project came online in July 2011. It generated 59,000 megawatts, the First Wind report states.
According to First Wind estimates, the four projects powered roughly the equivalent of 64,000 Maine homes and helped prevent the creation or burning of close to a million tons of pollutants and oil in 2011. Those estimates are based on U.S. Department of Energy data and standards, Lamontagne said.
