History
The Oklahoma State Legislature authorized the formation of the Oklahoma Municipal Power Authority in June 1981 with the passage of the Oklahoma Municipal Power Authority Act.

OMPA was created with the purpose of providing adequate, reliable and economic sources of electric power and energy to Oklahoma municipalities and public trusts operating municipal electric systems on June 2, 1981. This would allow members the financial benefits of a large utility while maintaining control of their electric utility.

By December 1984, 26 cities had signed power sales contracts. Then on July 1, 1985, OMPA came into existence as a full fledged power supplier. After the success of the first year, 6 more cities joined and in 1989 Fairview joined. In 1993, Perry became OMPA's 34th member when the council signed a power sales contract. Manitou became the 35th member in 1995. Purcell recently became OMPA's 36th member city on September 1, 2008. In addition, OMPA provides supplemental power to four cities in Kansas.

OMPA's power supply comes from a variety of resources; wind, hydro, natural gas, coal and others. Fairview, Kingfisher, Mangum, Pawhuska and Ponca City own small generating facilities, and when necessary OMPA schedules and purchases the generated power.
