Transmission 2013


  • Of the seven Independent System Operators (ISOs) and Regional Transmission Organizations (RTOs) in the United States, Midwest ISO had the most wind on its system with 12,870 MW at the close of 2013, closely followed by ERCOT with 12,268 MW.
  • During 2013, wind energy generation records were broken in ERCOT, SPP, CAISO, Xcel Energy’s system and Bonneville Power Administration.
  • During 2013, four major transmission projects were completed, providing enough capacity to carry 10,000 MW of new wind capacity.
  • In addition to the four transmission projects completed during 2013, there were 15 near-term transmission projects in advanced development -- spanning the Plains states, Upper Midwest, and the West -- expected to be completed prior to 2018. These projects could carry an estimated 60,000 MW of additional wind power capacity.
  • Wind power projects totaling 114,087 MW were in the interconnection queue at the end of 2013.
