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.
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.
