§45. Electricity produced from certain renewable resources, etc.

(a) General rule

For purposes of section 38, the renewable electricity production credit for any taxable year is an amount equal to the product of-

(B) sold by the taxpayer to an unrelated person during the taxable year.

(b) Limitations and adjustments

(1) Phaseout of credit

The amount of the credit determined under subsection (a) shall be reduced by an amount which bears the same ratio to the amount of the credit (determined without regard to this paragraph) as-

(A) the amount by which the reference price for the calendar year in which the sale occurs exceeds 8 cents, bears to

(B) 3 cents.

(2) Credit and phaseout adjustment based on inflation

The 0.3 cent amount in subsection (a), the 8 cent amount in paragraph (1), the $4.375 amount in subsection (e)(8)(A), the $2 amount in subsection (e)(8)(D)(ii)(I), and in subsection (e)(8)(B)(i) the reference price of fuel used as a feedstock (within the meaning of subsection (c)(7)(A)) in 2002 shall each be adjusted by multiplying such amount by the inflation adjustment factor for the calendar year in which the sale occurs. If the 0.3 cent amount as increased under the preceding sentence is not a multiple of 0.05 cent, such amount shall be rounded to the nearest multiple of 0.05 cent. In any other case, if an amount as increased under this paragraph is not a multiple of 0.1 cent, such amount shall be rounded to the nearest multiple of 0.1 cent.

(3) Credit reduced for tax-exempt bonds
