California is not the only US state where repowering is in the news. On the other side of the country, Princeton voters approved by a three to one margin a repowering plan for a small 320 kW wind project in Massachusetts. Community Energy Inc, a renewable power marketer, will remove eight Enertech 40 kW turbines and replace them with two 1.5 MW turbines (both GE Wind Energy and NEG Micon turbines are being considered), says the company's Michael Tennis. The turbines at Wachusett wind farm, the oldest wind project west of the Mississippi River, were constructed in 1983 and are still operating. The repowering will increase the project's output more than six-fold and provide more than 40% of the town's energy. This is Community Energy's first foray into developing a project in New England. Although the town's board of commissioners unanimously approved the repowering project late last year, it decided to send the issue to the voters, some of whom opposed the project due to the visual impact of the 230-foot towers. Community Energy, which is a pioneer in the sale of wind energy credits to consumers, is looking for markets for tradable credits from the repowered project, which is scheduled for completion in November, Tennis says.
