As total U.S. installed wind capacity approaches 100 gigawatts (GW), more than 40 percent remains concentrated in midwestern states. Significant levels of wind generation impact operations in both the Mid-continent Independent System Operator (MISO) and the Southwest Power Pool (SPP), the two competitive electricity markets that make up the region. In April 2019, SPP even set the record for wind penetration, with 66.5 percent of power in the region supplied by wind. As installed wind capacity continues to climb, both markets expect to see more wind generation come online in the next few years. As a result, asset owners in the midwestern electricity markets must maintain awareness of the impact new wind builds can have on both the marginal energy cost of power at their generators and the congestion on surrounding transmission lines.
