In the Great Plains, wind energy is cheap. Crazy cheap. With the lowest levelized costs approaching $10 per megawatt-hour and thousands of megawatts being procured for under $20 per megawatt-hour, PPAs for new wind farms cost less than just the fuel required to run existing coal or natural gas plants. These economics have driven a wind boom in the region: renewable energy made up three-fourths of the new capacity built in the Upper Midwest in the last five years, and virtually all of the region’s active projects in the MISO Interconnection Queue are wind and solar farms.
