Invenergy Wind and DTE Energy have begun construction on the 212.8MW Gratiot County wind project in Michigan, US.
The wind farm is located on private land near the town of Breckenridge in the townships of Wheeler, Bethany, Emerson and Lafayette.
Upon completion, the wind project is expected to generate enough clean, renewable energy to power nearly 50,000 households.
The project, featuring 133 units of the 1.6MW GE turbine, will interconnect into an existing 138kV transmission line owned by International Transmission Company.
Under a 20-year power purchase agreement, DTE Energy will own and operate half of the wind farm and purchase the remaining power from Invenergy.
The facility, which is being built by Aristeo Construction, is expected to start commercial operations in the first quarter of 2012.
