While Cape Wind is debated, land-based development of wind power takes off


Despite controversy that has slowed the Cape Wind project in Nantucket Sound, land-based wind farms are expanding rapidly in the region.

One company alone, First Wind Holdings LLC of Boston, has installed enough turbines in the Northeast over the past few years to generate nearly as much power as the long-awaited offshore wind farm. Other companies, too, have developed wind projects in New England states.

Driving this growth are technological advances reducing the cost of wind turbines and increasing their efficiency, making wind power more competitive with traditional power sources — particularly in the Northeast, where electricity costs can run as much as 60 percent above the national average.

Turbine prices have dropped about 30 percent over the past few years, and new turbines are able to generate electricity at lower wind speeds.

Meanwhile, average electricity prices in the Northeast can top 15 cents per kilowatt hour, compared to a US average of 9.52 cents. New wind technology can generate power at an average cost of about 10 cents per kilowatt hour, excluding subsidies, according to the US Energy Department.

“Some of the states in the Northeast have been some of the fastest-growing markets,” said Elizabeth Salerno, director of industry data and analysis at the American Wind Energy Association, a trade group in Washington. “Power prices are relatively high [there], so by delivering wind projects, you can develop a pretty affordable source of generation.”

First Wind has built wind farms in eight locations in Maine, Vermont, and upstate New York. With the 34 megawatts that will be added when the company completes its wind farm near Eastbrook, Maine, First Wind’s projects will have the capacity to generate nearly 420 megawatts of electricity, compared to Cape Wind’s 468 megawatts.... continued
