The Chickasaw Tribal Utility Authority was created by act of the Chickasaw Tribal Legislature on October 17, 1986 (Chickasaw Nation Tribal Code, Section 2-108.1.). CTUA provides electrical, water, sewer and natural gas services. The services provided by CTUA are structured so that the Chickasaw Nation saves money and the authority makes money. This is done by purchasing electricity and natural gas-by contract-at a wholesale rate from a supplier then reselling that power to our customers at a discount rate. CTUA is the first tribal utility authority in the U.S. to provide electrical power both on and off tribal property.

Electrical customers include numerous tribal government facilities (senior citizens centers; housing authority offices; the Chickasaw Nation Medical Center and its three clinics; Kullihoma, etc.), tribal commercial facilities (tobacco shops; casinos; travel plazas; Bedre manufacturing facility; CNI Manufacturing; tribal hotels and restaurants; Chickasaw Nation Division of Commerce administration; McSwain Theater, etc.). Non-tribal commercial customers include Southwestern Bell; Flex-n-Gate Manufacturing; the Bureau of Indian Affairs; T-Mobile and the Indian Health Service. CTUA was licensed in March 1990 by the Federal Energy Regulatory Commission to purchase power at wholesale for resale at retail rate. CTUA now purchases hydroelectric power from the Grand River Dam Authority and wheels that electrical power through CTUA's own distribution system to its customers. In addition, CTUA operates sewage/wastewater treatment plants that serve tribal facilities in Thackerville and Duncan, Oklahoma.

Lift stations are located at Davis - Treasure Valley, Goldsby Gaming Center, River Wind, Lazer Zone, Chickasaw Retreat and Conference Center, Salt Creek casino Lagoon & irrigation operations in Washington, Oklahoma provide services to Riverwind and Goldsby.
