BASED
ON
INVESTMENT
IN 
FACILITY.— 
‘‘(A) IN
GENERAL.—In the case of any 
qualified facility originally placed in service 
after December 31, 2009, the amount of the 
credit determined under subsection (a) for any
taxable year with respect to electricity produced 
at such facility shall not exceed the product 
of— 
‘‘(i) the applicable percentage with re-
spect to such facility, multiplied by 
‘‘(ii) the eligible basis of such facility. 
‘‘(B) CARRYFORWARD OF UNUSED LIMITA-
TION AND EXCESS CREDIT.— 
‘‘(i) UNUSED
LIMITATION.—If the 
limitation imposed under subparagraph (A) 
with respect to any facility for any taxable 
year exceeds the prelimitation credit for 
such facility for such taxable year, the lim-
itation imposed under subparagraph (A) 
with respect to such facility for the suc-
ceeding taxable year shall be increased by 
the amount of such excess. 
‘‘(ii) 
EXCESS
CREDIT.—If 
the 
prelimitation credit with respect to any fa-
cility for any taxable year exceeds the limi-
tation imposed under subparagraph (A) 
with respect to such facility for such tax-
able year, the credit determined under sub-
section (a) with respect to such facility for 
the succeeding taxable year (determined
before the application of subparagraph (A) 
for such succeeding taxable year) shall be 
increased by the amount of such excess. 
With respect to any facility, no amount 
may be carried forward under this clause 
to any taxable year beginning after the 10- 
year 
period 
described 
in 
subsection 
(a)(2)(A)(ii) with respect to such facility.

CREDIT.—The 
term ‘prelimitation credit’ with respect to 
any facility for a taxable year means the 
credit determined under subsection (a)

count any increase for such taxable year 
under clause (ii).

APPLICABLE
PERCENTAGE.—For 
purposes of this paragraph— 
‘‘(i) IN GENERAL.—The term ‘applica-
ble percentage’ means, with respect to any 
facility, the appropriate percentage pre-
scribed by the Secretary for the month in 
which such facility is originally placed in 
service.
‘‘(ii) METHOD
OF
PRESCRIBING
AP-
PLICABLE PERCENTAGES.—The applicable 
percentages prescribed by the Secretary for 
any month under clause (i) shall be per-
centages which yield over a 10-year period 
amounts of limitation under subparagraph 
(A) which have a present value equal to 35 
percent of the eligible basis of the facility.

OF
DISCOUNTING.—

year of the 10-year period referred to 
in clause (ii),

equal to the greater of 110 percent of 
the Federal long-term rate as in effect 
under section 1274(d) for the month 
preceding the month for which the ap-
plicable percentage is being pre-
scribed, or 4.5 percent, and

erty in proportion to projected generation 
from such facilities. 
‘‘(iii) 
SHARED
QUALIFIED
PROP-
ERTY.—For purposes of this paragraph,

with respect to any facility, any property 
described in section 168(e)(3)(B)(vi)—

require for utilization of such facility, 
and 
‘‘(II) which is not a qualified fa-
cility. 
‘‘(iv) SPECIAL
RULE
RELATING
TO 
GEOTHERMAL FACILITIES.—In the case of 
any qualified facility using geothermal en-
ergy to produce electricity, the basis of 
such facility for purposes of this paragraph 
shall be determined as though intangible 
drilling and development costs described in 
section 263(c) were capitalized rather than 
expensed. 
‘‘(E) SPECIAL RULE FOR FIRST AND LAST 
YEAR OF CREDIT PERIOD.—In the case of any 
taxable year any portion of which is not within 
the 10-year period described in subsection 
(a)(2)(A)(ii) with respect to any facility, the 
amount of the limitation under subparagraph 
(A) with respect to such facility shall be re-

portion of the taxable year which is not within 
such period bears to the entire taxable year.

PLACED IN SERVICE IN A YEAR AS 1 FACIL-
ITY.—At the election of the taxpayer, all quali-
