‘Sec. 1. 35-A MRSA §703, sub-§3-A, as enacted by PL 1995, c. 254, §3, is repealed and the following enacted in its place:
3-A. Special contracts. A public utility, subject to the commission's approval, may make a contract for a definite term for its product or service, but the published rates for the product or service may not be changed during the term of the contract without the commission's consent. If the commission grants to a telephone utility or a group of telephone utilities an exemption pursuant to section 307-A from the requirement to file rate schedules or terms and conditions, that telephone utility or group of telephone utilities is exempt from the requirements for commission approval and consent under this subsection to the same extent as the exemption granted by the commission pursuant to section 307-A.’
