A proposal to build Connecticut’s first wind farm in the state’s Northwest Corner has been blowing around for several years. Now an appeal brought by a citizens’ group that opposes the project will be heard by the state Supreme Court in coming months.

The key question is whether the Connecticut Siting Council had jurisdiction when it approved the wind turbine electric generation project. Since 2010, West Hartford-based BNE Energy Inc. has been pressing forward with plans to establish the commercial wind farm in the Litchfield County town of Colebrook.
