DERBY — Vermont utility regulators have approved a small wind turbine for a hilly field in Derby.

The turbine would become the fourth of its size in the town, which is near Canada.

The Vermont Public Service Board recently granted a certificate of public good for a 140-foot-tall windmill to Michele Judd in Derby. The turbine with blades 23 feet in diameter will go up not far from a similar one owned by her father. The turbine has the capacity to generate 10 kilowatts of electricity.

One neighbor opposed the project, raising concerns about noise and aesthetics. But the board found she did not raise “significant” issues.
