(a) Agencies are authorized to enter into performance-based contracts with qualified providers of energy-conservation measures for the purpose of significantly reducing energy operating costs of agency owned buildings, subject to the requirements of this section.

(b) Before entering into a contract or before the installation of equipment, modifications or remodeling to be furnished under a contract, the qualified provider shall first issue a proposal summarizing the scope of work to be performed. A proposal must contain estimates of all costs of installation, modifications or remodeling, including the costs of design, engineering, installation, maintenance, repairs or debt service, as well as estimates of the amounts by which energy operating costs will be reduced. If the agency finds, after receiving the proposal, that the proposal includes one or more energy-conservation measures, the installation of which is guaranteed to result in a net savings of a minimum of five percent of the then current energy operating costs which savings will, at a minimum, satisfy any debt service required, the agency may enter into a contract with the provider pursuant to this section.

(c) An energy-savings contract must include the following:

(1) A guarantee of a specific minimum net percentage amount of at least five percent of energy operating costs each year over the term of the contract that the agency will save;

(2) A statement of all costs of energy-conservation measures, including the costs of design, engineering, installation, maintenance, repairs and operations; and

(3) A provision that payments, except obligations upon termination of the contract before its expiration, are to be made over time.

(d) An agency may supplement its payments with federal, state or local funds to reduce the annual cost or to lower the initial amount to be financed.

(e) An energy-savings contract is subject to competitive bidding requirements and other requirements of article three of this chapter.

(f) An energy-savings contract may extend beyond the fiscal year in which it first becomes effective: Provided, That such a contract may not exceed a fifteen-year term: Provided, however, That the long term contract will be void unless the agreement provides that the agency shall have the option during each fiscal year of the contract to terminate the agreement.

(g) Agencies may enter into a "lease with an option to purchase" contract for the purchase and installation of energy-conservation measures if the term of the lease does not exceed fifteen years and the lease contract includes the provisions contained in subsection (f) of this section and meets federal tax requirements for tax-exempt municipal leasing or long-term financing. (h) The agency may include in its annual budget for each fiscal year any amounts payable under long-term energy-savings contracts during that fiscal year. (i) Upon the issuance of a request for proposals or request for quotations for an energy-savings contract, the agency shall provide a copy thereof to the Joint Committee on Government and Finance.

(j) Before signing an energy-savings contract or extending an existing energy-savings contract, the agency shall give thirty days' written notice, which notice shall include a copy of the proposal containing the information required by subsection (b) of this section, to the Joint Committee on Government and Finance.
