Erection of the 37 Gamesa 2MW turbines has resumed after being suspended while engineers conducted extensive testing on the concrete pedestals — where the tower is fixed to the foundation. Problems were first identified in early November.

Hardscrabble is one of the first wind farms in the country to use 100-metre towers, a detail Mortenson touted in announ-cing its selection for the project in May. The company, whose contract includes foundations, turbine erection and other ancillary structures, did not return a request for comment.
