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.
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.
