The Harvest II Wind Project in Huron County, in the east of the state will use 33 V100 1.8MW low wind-speed turbines.
The deal comes with a 10-year service agreement. Delivery is scheduled for mid-2012 with commissioning expected at the end of the year.
Exelon has a power purchase agreement in place with Consumers Energy.
In February, the Huron County Planning Commission voted to recommend the creation of a new wind district to facilitate the expansion of Exelon’s 33MW Harvest I wind farm.
