Okla. Stat. tit. 17, § 17-158.23: Geographical areas

It is hereby declared to be in the public interest that, in

order to encourage the orderly development of coordinated statewide

retail electric service, to avoid wasteful duplication of

distribution facilities, to avoid unnecessary encumbering of the

landscape of the State of Oklahoma, to prevent the waste of

materials and natural resources, for the public convenience and

necessity and to minimize disputes between retail electric suppliers

which may result in inconvenience, diminished efficiency and higher

costs in serving the consumer, the state be divided into

geographical areas, establishing the unincorporated areas within

which each retail electric supplier is to provide the retail

electric service as provided in this act.
