Is anyone permitting the installation of wind turbine generators? If so, are they listed? We recently had a submittal for a helix type wind turbine that will help to feed a commercial building. The turbine is not a listed piece of equipment, so we are asking for a field evaluation to be performed by a field evaluation services organization before we will approve it. So far this is the first submittal we have seen for a wind turbine. If anyone has had one installed in their jurisdiction I would be glad to hear how it was handled.
