Wind power in Missouri has an installed capacity of 959 MW from 499 turbines, as of 2016.^[1] This provided 1.29% of the state's electricity production.^[2]

Missouri's total wind generation potential is estimated to be 340 GW.^[1]

As of 2016, Missouri had 959 MW of installed capacity, all installed in the north-west corner of the state.^[1] At least six wind farms were developed byWind Capital Group between 2006 and 2009. As of 2017, the largest wind farm in the state came online, the 300 MW Rock Creek Wind Farm inAtchison County.^[3]

Northwest Missouri is considered the windiest portion of the state and clips the windiest portion of the country which is known asTornado Alley.

There have been several attempts at getting regulatory approval oftransmission lines to carry wind power, either to the load centers of Missouri, or through Missouri, from major wind power producers in theGreat Plains states to load centers further east.

• TheMidwest Transmission Project is a 180-mile 345-kV transmission line which became active in 2017. It connects theOmaha Public Power District (at itsNebraska City, Nebraska substation with theKansas City Power & Light substation atSibley, Missouri and has one major substation inMaryville, Missouri. The line was not specifically designed to supplement the wind grid but FAQ notes it "will create opportunities for existing and new future wind energy to access to the regional transmission system." It is a priority project of theSouthwest Power Pool.^[24]
• TheMark Twain Transmission Project was proposed byAmeren to connectPalmyra,Kirksville andIowa.^[25] Approval was given for construction by each of the counties the transmission lines passed through, and the line was energized in January 2020.^[26]

• TheGrain Belt Express is a proposed 4 GW transmission line from westernKansas toIndiana.^[27][28] TheMissouri Public Service Commission twice rejected the proposal, initially due to questions of the benefits of the project to the state, and later due to a lack of assent from all counties.^[29][30] TheMissouri Eastern District Court of Appeals ruled the commission erred in its second rejection,^[31] but sent the case to theMissouri Supreme Court.^[28] The company was awarded the right to use imminent domain for the necessary easments to complete the project, but asserted that most had been acquired through negotiations with landowners.^[32] TheDepartment of Energy awarded the project a $4.9 billion conditional loan guarantee in late 2024.^[32] This loan guarantee was later canceled in 2025, though the project was reported as continuing with private financing as of September 2025.^[33][34]

In October 2017, theEmpire District Electric Company proposed installing 500 MW of wind turbines inJasper,Barton,Dade, andLawrence counties.^[35][36][37]

In February 2019,E.ON announced plans for a 150 MW wind farm northwest ofColumbia, Missouri in ruralBoone County.^[38]
