Section 1303 of the Energy Tax Incentives Act of 2005, Pub. L. No. 109–58, added § 54 to the Code. In general, § 54 authorizes up to $800,000,000 of tax credit bonds to be issued by qualified issuers to finance certain renewable energy projects described in § 45(d) of the Code.

Section 54(a) provides that a taxpayer that holds a “clean renewable energy bond” on one or more credit allowance dates of the bond occurring during any taxable year is allowed as a nonrefundable credit against Federal income tax for the taxable year an amount equal to the sum of the credits determined under § 54(b) with respect to such dates. Section 54(d) provides that a “clean renewable energy bond” means any bond issued as part of an issue if: (1) the bond is issued by a qualified issuer pursuant to an allocation by the Secretary to the issuer of a portion of the national clean renewable energy bond limitation under § 54(f)(2); (2) 95 percent or more of the proceeds of the issue are to be used for capital expenditures incurred by qualified borrowers for one or more qualified projects; (3) the qualified issuer designates the bond for purposes of § 54 and the bond is in registered form; and (4) the issue meets certain requirements described in § 54(h) with respect to the expenditure of bond proceeds.

Section 54(j)(4) defines a “qualified issuer” as: (1) a clean renewable energy bond lender (as defined in § 54(j)(2)); (2) a cooperative electric company (as defined in § 54(j)(1)); or (3) a governmental body. Section 54(j)(3) defines the term “governmental body” as any State, territory, possession of the United States, the District of Columbia, Indian tribal government, or any political subdivision thereof. Section 54(j)(5) provides that a “qualified borrower” is: (1) a mutual or cooperative electric company described in § 501(c)(12) or § 1381(a)(2)(C); or (2) a governmental body. Section 54(d)(2)(A) defines the term “qualified project” as any of the qualified facilities described in §§ 45(d)(1) through (d)(9) (determined without regard to any placed in service date) owned by a qualified borrower.

Notice 2005–98 solicits applications for allocations of the $800,000,000 clean renewable energy bond limitation and provides guidance on certain other matters under § 54.
