GRDA has been producing and delivering low-cost, reliable electricity since 1940. Since that time, it has grown from a small, local producer of hydroelectricity to a major power supplier across the region. GRDA’s diverse electric generation portfolio includes gas, coal, water and wind resources. Electricity is transmitted across a four-state region via a sophisticated energy delivery network.
GRDA is a proud member of the Southwest Power Pool, the American Public Power Association and the Large Public Power Council, as well as the Oklahoma Municipal Alliance.
In March 2022, GRDA was given the “Reliable Public Power Provider” (RP3) Diamond level designation from the American Public Power Association. These awards are valid for a period of three years. GRDA achieved the Platinum level designation in 2019. To be awarded a RP3 designation, a public power utility must complete a rigorous online application that includes supporting documents to show evidence of best practices in reliability, safety, workforce development, and system improvement. An 18-member panel of national public power experts score the application. To achieve the Diamond level designation, you must meet 98-100% of the program criteria.
