Property which is to be a component part of, or is otherwise to be included in, any building to which this subsection applies shall be taken into account—

(i) at a time not earlier than the time at which it becomes irrevocably devoted to use in the building, and

(ii) as if (at the time referred to in clause (i)) the taxpayer had expended an amount equal to that portion of the cost to the taxpayer of such component or other property which, for purposes of this subpart, is properly chargeable (during such taxable year) to capital account with respect to such building.

(B) Certain borrowing disregarded

Any amount borrowed directly or indirectly by the taxpayer from the person rehabilitating the property for him shall not be treated as an amount expended for such rehabilitation.

(C) Limitation for buildings which are not self-rehabilitated

(i) In general

In the case of a building which is not self-rehabilitated, the amount taken into account under paragraph (1)(B) for any taxable year shall not exceed the amount which represents the portion of the overall cost to the taxpayer of the rehabilitation which is properly attributable to the portion of the rehabilitation which is completed during such taxable year.

(ii) Carryover of certain amounts

In the case of a building which is not a self-rehabilitated building, if for the taxable year—

(I) the amount which (but for clause (i)) would have been taken into account under paragraph (1)(B) exceeds the limitation of clause (i), then the amount of such excess shall be taken into account under paragraph (1)(B) for the succeeding taxable year, or

(II) the limitation of clause (i) exceeds the amount taken into account under paragraph (1)(B), then the amount of such excess shall increase the limitation of clause (i) for the succeeding taxable year.

The determination under subparagraph (C)(i) of the portion of the overall cost to the taxpayer of the rehabilitation which is properly attributable to rehabilitation completed during any taxable year shall be made, under regulations prescribed by the Secretary, on the basis of engineering or architectural estimates or on the basis of cost accounting records. Unless the taxpayer establishes otherwise by clear and convincing evidence, the rehabilitation shall be deemed to be completed not more rapidly than ratably over the normal rehabilitation period.

or for any taxable year thereafter.

(5) Election

This subsection shall apply to any taxpayer only if such taxpayer has made an election under this paragraph. Such an election shall apply to the taxable year for which made and all subsequent taxable years. Such an election, once made, may be revoked only with the consent of the Secretary.

For purposes of the performance requirement specified for the removal of SO₂ in the table contained in subparagraph (B), the SO₂ removal design level in the case of a unit designed for the use of feedstock substantially all of which is subbituminous coal shall be 99 percent SO₂ removal or the achievement of an emission level of 0.04 pounds or less of SO₂ per million Btu, determined on a 30-day average.

(2) Design net heat rate

For purposes of this subsection, design net heat rate with respect to an electric generation unit shall—

(A) be measured in Btu per kilowatt hour (higher heating value),

(B) be based on the design annual heat input to the unit and the rated net electrical power, fuels, and chemicals output of the unit (determined without regard to the cogeneration of steam by the unit),

(i) if the heat content is less than 13,500 Btu per pound, but greater than 7,000 Btu per pound, according to the following formula: design net heat rate = unit net heat rate x [1–[((13,500-design coal heat content, Btu per pound)/1,000)* 0.013]], and

(ii) if the heat content is less than or equal to 7,000 Btu per pound, according to the following formula: design net heat rate = unit net heat rate x [1–[((13,500-design coal heat content, Btu per pound)/1,000)* 0.018]], and

(D) be corrected for the site reference conditions of—

(i) elevation above sea level of 500 feet,

(A) 7 percentage points for coal of more than 9,000 Btu,

(B) 6 percentage points for coal of 7,000 to 9,000 Btu, or

(C) 4 percentage points for coal of less than 7,000 Btu.

(g) Applicability

No use of technology (or level of emission reduction solely by reason of the use of the technology), and no achievement of any emission reduction by the demonstration of any technology or performance level, by or at one or more facilities with respect to which a credit is allowed under this section, shall be considered to indicate that the technology or performance level is—

(1) adequately demonstrated for purposes of section 111 of the Clean Air Act (42 U.S.C. 7411);

(2) achievable for purposes of section 169 of that Act (42 U.S.C. 7479); or

(1) is consistent with the objectives of such section,

(2) is requested by the recipient of the competitive certification award, and

(3) involves moving the project site to improve the potential to capture and sequester carbon dioxide emissions, reduce costs of transporting feedstock, and serve a broader customer base,

unless the Secretary determines that the dollar amount of tax credits available to the taxpayer under such section would increase as a result of the modification or such modification would result in such project not being originally certified. In considering any such modification, the Secretary shall consult with other relevant Federal agencies, including the Department of Energy.

(i) Recapture of credit for failure to sequester

The Secretary shall provide for recapturing the benefit of any credit allowable under subsection (a) with respect to any project which fails to attain or maintain the separation and sequestration requirements of subsection (e)(1)(G).

(A) In general

If, at the close of a taxable year following the taxable year in which the property was placed in service, there is a net decrease in the amount of nonqualified nonrecourse financing with respect to such property, such net decrease shall be taken into account as an increase in the credit base for such property in accordance with subparagraph (C).

For purposes of determining the amount of credit subject to the early disposition or cessation rules of section 50(a), the net increase in the amount of the nonqualified nonrecourse financing with respect to the property shall be treated as reducing the property's credit base in the year in which the property was first placed in service.

For purposes of paragraph (1), the amount of nonqualified nonrecourse financing (within the meaning of subsection (a)(1)(D)) with respect to the taxpayer shall not be treated as increased by reason of a transfer of (or agreement to transfer) any evidence of any indebtedness if such transfer occurs (or such agreement is entered into) more than 1 year after the date such indebtedness was incurred.
