Tennessee Code Title 4. State Government § 4-31-119

(a) The state delegates to the Tennessee local development authority the authority to allocate on behalf of the state the portion of the “national qualified energy conservation bond limitation,” as defined in § 54D of the Internal Revenue Code of 1986 (26 U.S.C. § 54D), that is allocated to the state pursuant to § 54D, in a manner consistent therewith.  The authority may make such allocations from a list of recommended allocations presented to it by the department of economic and community development.  The department shall consider both state and local government projects and issuers when developing recommendations.

(b) The department of economic and community development shall serve as the coordinator and administrator of such qualified energy conservation bond programs, establishing the terms and provisions of the programs and adopting such procedures with respect to such programs as necessary or appropriate.

(c) The authority has the power and is authorized to issue its negotiable bonds for a qualified energy conservation project as a capital project under part 4 of this chapter if the commissioner of economic and community development certifies that such project complies with a qualified energy conservation bond program developed by the department, which certification shall be conclusive.  In applying § 47-14-103, and related provisions of title 47, chapter 14, to such bonds issued by the authority, the effective rate of the interest on any such bond shall be determined by reducing the interest payable by the authority with respect to such bond by the amount of payments from the United States treasury department that the authority expected, at the time of the issuance of such bond, to receive with respect to such bond.
