ITCTransmission is making a major investment in the Thumb area’s highvoltage electric grid. We are developing a new 140-mile transmission line and four new substations which together will help increase transmission systemreliability, reduce system congestion, providemore efficient transmission of energy and serve as a “backbone” for future interconnection of new generation sources in the area, including wind.
As Phase 1 of the Thumb Loop proceeds toward completion in the third quarter of 2013, ITC is facilitating interconnections with wind farms being developed in the area. These interconnection projects include the Minden Substation connecting new DTE 60 MW Wind Farm near Harbor Beach, commissioned November 2012; The Stein Substation, connecting a new Next Era 150 MW Wind Farm, to be commissioned in Q4 2013; the Dixon Substation, connecting a new Next Era 101 MW Wind Farm, to be commissioned in Q4 2013; and the Harvest Wind Expansion, a 59.4 MW expansion by Exelon. ITC is adding a third transformer to the new Rapson substation by Q4 2013 to connect the Harvest Wind Expansion to the Thumb Loop.
