Our mission is to provide low-cost, reliable electric power and related services to our customers and to be responsive to the interests and concerns of public power users, the communities we affect, and the people of the state of Oklahoma.

The Grand River Dam Authority is an agency of the state of Oklahoma, created by the Oklahoma Legislature in 1935 to be a “conservation and reclamation district for the waters of the Grand River.”

Headquartered in Vinita, Oklahoma, the Grand River Dam Authority is a non-appropriated state agency, fully funded by revenues from the sale of electricity and water instead of tax dollars.

GRDA generates, transmits and sells electricity to Oklahoma municipalities, electric cooperatives and industrial customers, as well as off-system customers across a four-state region.

GRDA  manages over 70,000 surface acres of water in Northeast Oklahoma.

We pledge to assist in area economic development and help our customers adapt to changes in their business environments, as well as making certain that on and around our lakes we will support recreational development, environmental awareness, and good safety practices to ensure the continued improvement of the quality of life for all of those who utilize our resources.

The legislation which created the GRDA outlined its primary responsibilities this way:

  • To control, store and preserve, within the boundaries of the District, the water of the Grand River and its tributaries for any useful purpose and to use, distribute and sell the same within the boundaries of the District.
  • To develop and generate water power and electric energy within the boundaries of the District.

GRDA fulfills its responsibilities by operating three hydroelectric facilities and managing two lakes along the Grand River system. These facilities, along with the two coal burning units at the Grand River Energy Center (GREC), Red Bud facility and wind generation from several different Oklahoma wind farms combine to give GRDA a total electric generation capacity of close to 1,900 megawatts. In 2017, the new Unit 3 combined cycle gas generation plant came online at the GREC and has the potential to be the most efficient generator of its type in the United States. GRDA transmits and delivers this electricity across its 24-county service area in Northeast Oklahoma via a sophisticated energy delivery system. GRDA sells electricity to three customer classes: municipals, electric cooperatives and industries.
