Credit for Renewable Electricity Production and Publication of Inflation Adjustment Factor and Reference Price for Calendar Year 2023 
   
Notice 2023-51 
   
This notice publishes the inflation adjustment factor and reference price for calendar year 2023 for the renewable electricity production credit under section 45 of the Internal Revenue Code (section 45 credit). The 2023 inflation adjustment factor and reference price are used in determining the availability of the credit and apply to calendar year 2023 sales of kilowatt hours of electricity produced in the United States or a possession thereof from qualified energy resources.
   
BACKGROUND 
   
Section 45 was amended by section 13101 of Public Law 117-169, 136 Stat. 1818 (August 16, 2022), commonly known as the Inflation Reduction Act of 2022 (IRA). The IRA changed the manner in which the section 45 credit amounts are calculated for any qualified facility placed in service after December 31, 2021. The IRA also removed the one-half reduction of the credit amount under section 45(b)(4)(A) for qualified hydropower facilities and marine and hydrokinetic renewable energy facilities placed in service after December 31, 2022. In the case of any qualified facility placed in service before January 1, 2022, the section 45 credit amounts are determined under the calculation rules provided by the prior version of section 45.
   
As amended by the IRA, section 45(b)(6)(A) provides that, in the case of any qualified facility that satisfies the requirements of section 45(b)(6)(B), the credit amount determined under section 45(a) (determined after the application of section 45(b)(1) through (5) and without regard to section 45(b)(6)) is equal to such amount multiplied by 5. A qualified facility satisfies the requirements of section 45(b)(6)(B) if it is placed in service after December 31, 2021, and it is one of the following: (i) a facility with a maximum net output of less than 1 megawatt (as measured in alternating current); (ii) a facility the construction of which began prior to January 29, 2023, which is the date that is 60 days after the publication of the guidance with respect to the requirements of section 45(b)(7)(A) (prevailing wage requirements) and section 45(b)(8) (apprenticeship requirements); 1  or (iii) a facility that satisfies the requirements of section 45(b)(7)(A) and (8). The IRA also added bonus credit amounts with respect to qualified facilities placed in service after December 31, 2022, that meet domestic content requirements under section 45(b)(9) 2  or energy community requirements under section 45(b)(11). 3

The IRA amended the phaseout of the section 45 credit for wind facilities under section 45(b)(5) such that it does not apply to facilities placed in service after December 31, 2021. The IRA also added a new phaseout of the section 45 credit under section 45(b)(10) in the case of qualified facilities placed in service after December 31, 2022, for taxpayers making an elective payment election under section 6417. The IRA also amended the credit amount reduction under section 45(b)(3) in the case of qualified facilities the construction of which began after August 16, 2022.
   
The IRA amended section 45(d)(4) to restore the section 45 credit for electricity produced in solar energy facilities in the case of qualified facilities placed in service after December 31, 2021, and the construction of which begins before January 1, 2025. Effective for facilities placed in service after December 31, 2022, the IRA amended the definition of marine and hydrokinetic renewable energy under section 45(c)(10) and the definition of a marine and hydrokinetic renewable energy facility under section 45(d)(11). The IRA extended certain deadlines in the definitions under section 45(d) for wind facilities, closed-loop biomass facilities, open-loop biomass facilities, geothermal facilities, landfill gas facilities, trash facilities, qualified hydropower facilities, and marine and hydrokinetic renewable energy facilities.
   
Section 45(a) provides that the renewable electricity production credit for any tax year is an amount equal to the product of the kilowatt hours of specified electricity produced by the taxpayer and sold to an unrelated person during the tax year multiplied by 1.5 cents (in the case of a qualified facility placed in service before January 1, 2022) or 0.3 cents (in the case of a qualified facility placed in service after December 31, 2021). This electricity must be produced from qualified energy resources and at a qualified facility during the 10-year period beginning on the date the facility was originally placed in service.
   
Section 45(b)(1) provides that the amount of the credit determined under section 45(a) is reduced by an amount which bears the same ratio to the amount of the credit as the amount by which the reference price for the calendar year in which the sale occurs exceeds 8 cents, bears to 3 cents. Under section 45(b)(2), the 1.5 cent (or 0.3 cent) amount in section 45(a) and the 8 cent amount in section 45(b)(1) are each adjusted by multiplying such amount by the inflation adjustment factor for the calendar year in which the sale occurs. In the case of any qualified facility placed in service before January 1, 2022, if any amount as increased under section 45(b)(2) is not a multiple of 0.1 cent, such amount is rounded to the nearest multiple of 0.1 cent. In the case of any qualified facility placed in service after December 31, 2021, if the 0.3 cent amount as increased under section 45(b)(2) is not a multiple of 0.05 cent, such amount is rounded to the nearest multiple of 0.05 cent.
   
In the case of electricity produced in open-loop biomass facilities, landfill gas facilities, trash facilities, qualified hydropower facilities, and marine and hydrokinetic renewable energy facilities, section 45(b)(4)(A) requires the amount in effect under section 45(a)(1) (determined before rounding as required by section 45(b)(2)) to be reduced by one-half. As amended by the IRA, the one-half reduction under section 45(b)(4)(A) no longer applies to qualified hydropower facilities and marine and hydrokinetic renewable energy facilities placed in service after December 31, 2022.
   
Section 45(b)(5) provides that in the case of any qualified wind facility placed in service before January 1, 2022, the amount of the credit determined under section 45(a) (determined after the application of section 45(b)(1), (2), and (3) and without regard to section 45(b)(5)) shall be reduced by (A) in the case of any facility the construction of which began after December 31, 2016, and before January 1, 2018, 20 percent, (B) in the case of any facility the construction of which began after December 31, 2017, and before January 1, 2019, 40 percent, (C) in the case of any facility the construction of which began after December 31, 2018, and before January 1, 2020, 60 percent, and (D) in the case of any facility the construction of which began after December 31, 2019, and before January 1, 2022, 40 percent.
   
Section 45(c)(1) defines qualified energy resources as wind, closed-loop biomass, open-loop biomass, geothermal energy, solar energy, small irrigation power, 4  municipal solid waste, qualified hydropower production, and marine and hydrokinetic renewable energy.
   
4    The section 45 credit is expired for small irrigation power facilities.   
   
Section 45(d)(1) defines a qualified facility using wind to produce electricity as any facility owned by the taxpayer that is originally placed in service after December 31, 1993, and the construction of which begins before January 1, 2025. See  section 45(e)(7) for rules relating to the inapplicability of the credit to electricity sold to utilities under certain contracts.
   
Section 45(d)(2)(A) defines a qualified facility using closed-loop biomass to produce electricity as any facility owned by the taxpayer that is originally placed in service after December 31, 1992, and the construction of which begins before January 1, 2025, or owned by the taxpayer which before January 1, 2025, is originally placed in service and modified to use closed-loop biomass to co-fire with coal, with other biomass, or with both, but only if the modification is approved under the Biomass Power for Rural Development Programs or is part of a pilot project of the Commodity Credit Corporation as described in 65 FR 63052. For purposes of section 45(d)(2)(A)(ii), a facility shall be treated as modified before January 1, 2025, if the construction of such modification begins before such date. Section 45(d)(2)(C) provides that in the case of a qualified facility described in section 45(d)(2)(A)(ii), the 10-year period referred to in section 45(a) is treated as beginning no earlier than the date of the enactment of section 45(d)(2)(C)(i) (October 22, 2004), and if the owner of such facility is not the producer of the electricity, the person eligible for the credit allowable under section 45(a) is the lessee or the operator of such facility. A qualified facility using closed-loop biomass includes a new unit placed in service after the date of the enactment of section 45(d)(2)(B) (October 3, 2008) in connection with a qualified facility using closed-loop biomass, but only to the extent of the increased amount of electricity produced at the facility by reason of such new unit.
   
Section 45(d)(3)(A) defines a qualified facility using open-loop biomass to produce electricity as any facility owned by the taxpayer which in the case of a facility using agricultural livestock waste nutrients, is originally placed in service after the date of the enactment of section 45(d)(3)(A)(i)(I) (October 22, 2004) and the construction of which begins before January 1, 2025, and the nameplate capacity rating of which is not less than 150 kilowatts, and in the case of any other facility, the construction of which begins before January 1, 2025. In the case of any facility described in section 45(d)(3)(A), if the owner of such facility is not the producer of the electricity, section 45(d)(3)(C) provides that the person eligible for the credit allowable under section 45(a) is the lessee or the operator of such facility. A qualified facility using open-loop biomass includes a new unit placed in service after the date of the enactment of section 45(d)(3)(B) (October 3, 2008) in connection with a qualified facility using open-loop biomass, but only to the extent of the increased amount of electricity produced at the facility by reason of such new unit.
   
Section 45(d)(4) defines a qualified facility using geothermal energy to produce electricity as any facility owned by the taxpayer that is originally placed in service after the date of the enactment of section 45(d)(4) (October 22, 2004) and the construction of which begins before January 1, 2025. A qualified facility using geothermal energy does not include any property described in section 48(a)(3) the basis of which is taken into account by the taxpayer for purposes of determining the energy credit under section 48.
   
As amended by the IRA and effective for solar energy facilities placed in service after December 31, 2021, section 45(d)(4) also defines a qualified facility using solar energy to produce electricity as any facility owned by the taxpayer that is originally placed in service after the date of the enactment of section 45(d)(4) (October 22, 2004) and the construction of which begins before January 1, 2025. A qualified facility using solar energy does not include any property described in section 48(a)(3) the basis of which is taken into account by the taxpayer for purposes of determining the energy credit under section 48.
   
Section 45(d)(6) defines a qualified facility using gas derived from the biodegradation of municipal solid waste to produce electricity as any facility owned by the taxpayer that is originally placed in service after the date of the enactment of section 45(d)(6) (October 22, 2004) and the construction of which begins before January 1, 2025.
   
Section 45(d)(7) defines a qualified facility (other than a facility described in section 45(d)(6)) that uses municipal solid waste to produce electricity as any facility owned by the taxpayer that is originally placed in service after the date of the enactment of section 45(d)(7) (October 22, 2004) and the construction of which begins before January 1, 2025. A qualified facility using municipal solid waste includes a new unit placed in service in connection with a facility placed in service on or before the date of the enactment of section 45(d)(7), but only to the extent of the increased amount of electricity produced at the facility by reason of such new unit.
   
Section 45(d)(9) defines a qualified facility producing qualified hydroelectric production described in section 45(c)(8) as (i) any facility producing incremental hydropower production, but only to the extent of its incremental hydropower production attributable to efficiency improvements or additions to capacity described in section 45(c)(8)(B) placed in service after the date of the enactment of section 45(d)(9) (August 8, 2005) and before January 1, 2025, and (ii) any other facility placed in service after the date of the enactment of section 45(d)(9) (August 8, 2005) and the construction of which begins before January 1, 2025. Section 45(d)(9)(B) provides that, in the case of a qualified facility described in section 45(d)(9)(A), the 10-year period referred to in section 45(a) shall be treated as beginning on the date the efficiency improvements or additions to capacity are placed in service. Section 45(d)(9)(C) provides that for purposes of section 45(d)(9)(A)(i), an efficiency improvement or addition to capacity shall be treated as placed in service before January 1, 2025, if the construction of such improvement or addition begins before such date.
   
As amended by the IRA, section 45(d)(11) provides in the case of a facility producing electricity from marine and hydrokinetic renewable energy, the term "qualified facility" means any facility owned by the taxpayer which has a nameplate capacity rating of at least 150 kilowatts (or at least 25 kilowatts in the case of a facility placed in service after December 31, 2022), and is originally placed in service on or after the date of the enactment of section 45(d)(11) (October 3, 2008) and the construction of which begins before January 1, 2025.
   
Section 45(e)(2)(A) requires the Secretary to determine and publish in the Federal Register each calendar year the inflation adjustment factor and the reference price for such calendar year. The inflation adjustment factor and the reference price for the 2023 calendar year were published in the Federal Register at 88 FR 40400 on June 21, 2023.
   
Section 45(e)(2)(B) defines the inflation adjustment factor for a calendar year as a fraction the numerator of which is the GDP implicit price deflator for the preceding calendar year and the denominator of which is the GDP implicit price deflator for the calendar year 1992. The term "GDP implicit price deflator" means the most recent revision of the implicit price deflator for the gross domestic product as computed and published by the Department of Commerce before March 15 of the calendar year.
   
Section 45(e)(2)(C) provides that the reference price with respect to a calendar year is the Secretary's determination of the annual average contract price per kilowatt hour of electricity generated from the same qualified energy resource and sold in the previous year in the United States. Only contracts entered into after December 31, 1989 are taken into account.
   
INFLATION ADJUSTMENT FACTOR AND REFERENCE PRICE 
   
The inflation adjustment factor for calendar year 2023 for qualified energy resources is 1.8909.
   
The reference price for calendar year 2023 for facilities producing electricity from wind (based upon information provided by the Department of Energy) is 3.74 cents per kilowatt hour. The reference prices for facilities producing electricity from closed-loop biomass, open-loop biomass, geothermal energy, solar energy, municipal solid waste, qualified hydropower production, and marine and hydrokinetic energy have not been determined for calendar year 2023.
   
PHASEOUT CALCULATION 
   
Because the 2023 reference price for electricity produced from wind (3.74 cents per kilowatt hour) does not exceed 8 cents multiplied by the inflation adjustment factor (1.8909), the phaseout of the credit provided in section 45(b)(1) does not apply to such electricity sold during calendar year 2023. However, section 45(b)(5) provides an additional phaseout of the credit for wind facilities placed in service before January 1, 2022, and the construction of which began after December 31, 2016. For electricity produced from closed-loop biomass, open-loop biomass, geothermal energy, solar energy, municipal solid waste, qualified hydropower production, and marine and hydrokinetic energy, the phaseout of the credit provided in section 45(b)(1) does not apply to such electricity sold during calendar year 2023.
   
CREDIT AMOUNT FOR A QUALIFIED FACILITY PLACED IN SERVICE BEFORE JANUARY 1, 2022 
   
As required by section 45(b)(2), the 1.5 cent amount provided in section 45(a)(1) is adjusted by multiplying such amount by the inflation adjustment factor for the calendar year in which the sale occurs. If any amount as increased under section 45(b)(2) is not a multiple of 0.1 cent, such amount is rounded to the nearest multiple of 0.1 cent. In the case of electricity produced in open-loop biomass facilities, landfill gas facilities, trash facilities, qualified hydropower facilities, and marine and hydrokinetic renewable energy facilities, section 45(b)(4)(A) requires the amount in effect under section 45(a)(1) (before rounding to the nearest 0.1 cent as required by section 45(b)(2)) to be reduced by one-half.
   
Under the calculation required by section 45(b)(2), the credit for renewable electricity production for calendar year 2023 determined under section 45(a) is 2.8 cents per kilowatt hour on the sale of electricity produced in any qualified facility placed in service before January 1, 2022, from the qualified energy resources of wind, closed-loop biomass, and geothermal energy, and 1.4 cents per kilowatt hour on the sale of electricity produced in any qualified facility placed in service before January 1, 2022, from the qualified energy resources of open-loop biomass, landfill gas, trash, qualified hydropower, and marine and hydrokinetic energy.
   
CREDIT AMOUNT FOR A QUALIFIED FACILITY PLACED IN SERVICE AFTER DECEMBER 31, 2021 
   
As required by section 45(b)(2), the 0.3 cent amount provided in section 45(a)(1) is 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 adjusted for inflation is not a multiple of 0.05 cent, the amount is rounded to the nearest multiple of 0.05 cent. In the case of electricity produced in open-loop biomass facilities, landfill gas facilities, trash facilities, qualified hydropower facilities, and marine and hydrokinetic renewable energy facilities, section 45(b)(4)(A) requires the amount in effect under section 45(a)(1) (determined before rounding as required by section 45(b)(2)) to be reduced by one-half.
   
Under the calculation required by section 45(b)(2), the credit for renewable electricity production for calendar year 2023 determined under section 45(a) is 0.55 cents per kilowatt hour on the sale of electricity produced in any qualified facility placed in service after December 31, 2021, from the qualified energy resources of wind, closed-loop biomass, geothermal energy, and solar energy, and 0.3 cents per kilowatt hour on the sale of electricity produced in any qualified facility placed in service after December 31, 2021, from the qualified energy resources of open-loop biomass, landfill gas, trash, qualified hydropower, and marine and hydrokinetic renewable energy.
   
CREDIT AMOUNT FOR QUALIFIED HYDROPOWER FACILITIES AND MARINE AND HYDROKINETIC RENEWABLE ENERGY FACILITIES PLACED IN SERVICE AFTER DECEMBER 31, 2022 
   
Under the calculation required by section 45(b)(2), the credit for renewable electricity production for calendar year 2023 determined under section 45(a) is 0.55 cents per kilowatt hour on the sale of electricity produced in any qualified facility placed in service after December 31, 2022, from the qualified energy resources of qualified hydropower and marine and hydrokinetic renewable energy.
