Notwithstanding any other provision in this chapter to the contrary, an authority is not authorized to distribute electric energy for retail sale unless the authority is an authority created by a governmental unit exempt from the referendum requirement of § 15.2-5403. Such distribution shall be limited to retail sales within the geographic area that was, as of January 1, 2006, by the governmental unit of such authority. Nothing in this chapter shall be construed to impair or abridge the exclusive territorial electric distribution rights or property rights of any certificated incumbent public service company operating in the Commonwealth. No such authority is authorized or empowered to take by condemnation, eminent domain, or otherwise, the electric distribution system, utility facilities, or other utility property of any public service company without the consent of such public service company.
