Wind Farm Coming to US 'Dead Zone for Wind Power'

On a vast tract of old North Carolina farmland, crews are getting ready to build something the South has never seen: a commercial-scale wind energy farm. The $600 million project by Spanish developer Iberdrola Renewables will put 102 turbines on 22,000 acres near the coastal community of Elizabeth City, with plans to add about 50 more. Once up and running, it could generate about 204 megawatts—enough to power about 60,000 homes. It would be the first large onshore wind farm in a region with light, fluctuating winds that has long been a dead zone for wind power, and after a years-long regulatory process that once looked to have doomed the plan, an Iberdrola spokesman says construction is to begin in about a month.

Right now, there's not a spark of electricity generated from wind in nine states across the Southeast from Arkansas to Florida, according to data from the American Wind Energy Association, an industry trade group, but taller towers and bigger turbines are unlocking new potential in the South. Federal energy researchers have found stronger winds at higher elevations that can be tapped by new towers and bigger rotor blades. New federal maps of onshore wind flows at higher elevations than were previously available indicate that this new technology significantly increases the areas in which wind can thrive, especially in the Southeast.
