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

(a) 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.

(b) 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 GRDA Coal-Fired Complex (thermal generation), combine for a total generation capability of 1,480 megawatts (MW). GRDA transmits and delivers this wholesale electricity across its 24-county service area in Northeast Oklahoma via a sophisticated energy delivery systems. GRDA sells electricity to three customer classes: municipals, electric cooperatives and industries.


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. 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.
