As the Thumb Loop project moves toward completion in 2015, ITC continues to facilitate interconnections with wind farms being developed in the area. These interconnection projects include the new Minden, Stein, Dixon, Ringle and Grassmere substations, an expansion of the new Rapson substation and other system upgrades in the Thumb area. As of the end of 2014 approximately 900 megawatts (MW) of wind generation have been connected to the ITC system in the Thumb area. By the end of 2015, when the third and final segment of the Thumb Loop is up and running, another 328 MW of wind energy is expected to come online, bringing the total renewable energy in the area to 1,228 MW -- enough energy to power about 325,000 homes.
