The recently released SPP WITF Wind Integration Study, conducted by Charles River Associates, found that enhanced electricity reserves and major transmission reinforcements are needed to integrate higher levels of wind generation into the SPP transmission system and energy markets. If the needed transmission upgrades were completed, there would be no significant technical barriers or reliability impacts to integrating wind energy levels up to 20%. Currently, approximately 4% of the region's electricity is generated by wind. To accommodate increased west-to-east flows while meeting SPP's electric reliability standards: For the 10% case, new transmission lines totaling 1,260 miles of 345 kV and 40 miles of 230 kV lines are needed. For the 20% case, an additional 485 miles of 765 kV, 766 miles of 345 kV, 205 miles of 230 kV, and 25 miles of 115 kV lines are needed. Read the full news release or download the study.
