Steps are underway for the development of Oklahoma’s latest windfarm, a 300-turbine project in the Panhandle.
Filings by the Southwest Power Pool indicated the States Edge Energy Center is a proposed 2-gigawatt wind energy project in Cimarron County and Texas County. The Invenergy project would be located between Guymon and Boise City.
“States Edge plans to construct a generating facility (“Facility”), which will consist of three hundred (300) GE 2.5 MW wind turbine generators for a total generating nameplate capacity of 750 MW. The First Revised States Edge GIA facilitates the interconnection of the Facility to AEP’s transmission system,” according to the SPP.
GIA refers to a Generator Interconnection Agreement.

Invenergy indicated it would be a $4 billion investment in northwest Oklahoma and the 2 GW was enough electricity to power more than 850,000 American homes. Up to 500 jobs would be supported during the construction.
The Chicago-based company said up to 30 full-time operations and maintenance staff would be employed once the wind project was completed and made operational. In promoting the project, Invenergy professed the wind farm would result in emissions reductions equivalent to 1 billion trees planted.
Reports indicate the energy center is in the development phase and not yet under construction. The project is still securing necessary permits and land rights, with construction anticipated to begin after the development phase is complete.
It is not the first Invenergy project in Oklahoma. The firm has wind farm operations it built in 10 counties in the state. The company built the Traverse Wind Energy Center in Blaine and Custer counties near Weatherford in 2022 and at the time was described as the biggest wind park built in a single phase in North America. The Center is owned by American Electric Power through its subsidiaries Southwestern Electric Power Company and Public Service Company of Oklahoma.
Another Invenergy development was the Maverick Wind Center consisting of 103 turbines near Enid. Combined with the Sundance Wind Energy Center in Alva and Woods counties, the two form the North Central Wind Energy facilities.
It developed the Centennial Wind project in Harper County and the Wagon Wheel Wind farm across Logan, Garfield, Kingfisher, Noble and Payne counties.
