Notice 2023-29 describes certain

rules that the Department of the Treasury (Treasury Department) and the Internal Revenue Service (IRS) intend to include

in forthcoming proposed regulations for determining what constitutes an energy community, as defined in § 45(b)(11)(B) and as adopted by §§ 45Y(g)(7), 48(a) (14), and 48E(a)(3)(A), and for determining whether a qualified facility, an energy project, or energy storage technology is located in an energy community. Notice 2023-29 also provides that the Treasury Department and the IRS intend to propose that the forthcoming proposed regulations will apply to taxable years ending after April 4, 2023. Taxpayers may rely on the rules described in sections 3 through 6 of Notice 2023-29 until the proposed regulations are published.

Sections 45(b)(11), 48(a)(14), 45Y(g) (7), and 48E(a)(3)(A) provide the requirements that taxpayers must satisfy to qualify EC Projects (defined in section 2 of Notice 2023-29) for increased energy community bonus credit amounts or rates under those provisions of the Code. Section 2 of Notice 2023-29 provides that the term “EC Project” refers to: (1) a qualified facility eligible for a credit determined under § 45 or determined under § 45Y that is located in an energy community; (2) an energy project eligible for a credit determined under § 48, which may include qualified property for which a taxpayer has made a valid irrevocable election under § 48(a) (5) to treat such qualified property as energy property under § 48, that is placed in service within an energy community; or (3) a qualified investment with respect to a qualified facility or energy storage technology eligible for a credit determined under § 48E that is placed in service within an energy community.

Section 45(b)(11)(B) identifies three location-based categories of energy communities for purposes of §§ 45, 45Y, 48, and 48E, described in Notice 2023-29 as the Brownfield Category, the Statistical Area Category, and the Coal Closure Category. The Statistical Area Category includes a metropolitan statistical area

(MSA) or non-metropolitan statistical area (non-MSA) that (1) has (or had at any time after December 31, 2009) 0.17 percent or greater direct employment (Fossil Fuel Employment) or 25 percent or greater local tax revenues (Fossil Fuel Tax Revenue) related to the extraction, processing, transport, or storage of coal, oil, or natural gas (as determined by the Secretary of the Treasury or her delegate (Secretary)); and (2) has an unemployment rate at or above the national average unemployment rate for the previous year (as determined by the Secretary).

Section 4 of Notice 2023-29 provides generally applicable rules for determining whether a qualified facility is located in an energy community under §§ 45 or 45Y, and under §§ 48 and 48E, whether an energy project, qualified facility, or energy storage technology, as applicable, is placed in service within an energy community. Section 4.02 of Notice 2023-29 provides that an EC Project is treated as located in or placed in service within an energy community if it satisfies either the Nameplate Capacity Test under section 4.02(1) of that notice or the Footprint Test under section 4.02(2) of that notice.

.02 The Nameplate Capacity Attribu- tion Rule . Under the Nameplate Capacity Test, an EC Project that has nameplate capacity is considered located in or placed in service within an energy community if 50 percent or more of the EC Project’s nameplate capacity is in an area that qualifies as an energy community. The Nameplate Capacity Test includes a Nameplate Capacity Attribution Rule (described in section 4.02(1)(b) of Notice 2023-29). The Nameplate Capacity Attribution Rule provides that if an EC Project with offshore energy generation units has nameplate capacity but none of the EC Project’s energy-generating units are in a census tract, MSA, or non-MSA, then the Nameplate Capacity Test for such EC Project is applied by attributing all the nameplate

as a port used either full or part-time to facilitate maritime operations necessary for the installation or operation and maintenance of the EC Project, and with a significant long-term relationship with the EC Project at which staff employed by, or working as independent contractors for, the taxpayer that owns the EC Project are based and perform functions essential to the EC Project’s operations. A port will be considered to have a significant long-term relationship with the EC Project only if the taxpayer that owns the EC Project owns (in whole or in part) or leases (in whole or in part) under a lease agreement with a term of at least 10 years, the port in which the EC Project SCADA equipment is located. Staff employed by, or working as independent contractors for, the taxpayer that owns the EC Project will be considered based in an EC Project Port to perform functions essential to the EC Project’s operations only if the staff perform (collectively, if not individually) all of the following functions: management of marine operations, inventory and handling of spare parts and consumables, and berthing and dispatch of operation and maintenance vessels and associated crews and technicians. .02 Modification of the Fossil Fuel Employment rate determination by the addition of two NAICS codes .

(1) The table in section 3.03(2) of Notice 2023-29 is modified to read as follows (new codes in bold):

capacity of such EC Project to the landbased power conditioning equipment that conditions energy generated by the EC Project for transmission, distribution, or use and that is closest to the point of interconnection. Section 3.01 of this notice expands the Nameplate Capacity Attribution Rule to include additional attribution property.

.03 NAICS codes used for determining the Fossil Fuel Employment rate . Section 3.03(2) of Notice 2023-29 provides that for purposes of determining whether an MSA or non-MSA is in the Statistical Area Category based on Fossil Fuel Employment, the relevant direct employment is determined by the number of people employed in the industries identified by the 2017 NAICS industry codes listed in the table in section 3.03(2) of Notice 2023-29. The Fossil Fuel Employment rate is determined as the number of people employed in the industries identified by the 2017 NAICS codes specified in the table and as listed in the annual County Files of the County Business Patterns (CBP) published by the Census Bureau, divided by the total number of people employed in that area. The Fossil Fuel Employment and total employment for each county in an MSA or non-MSA is aggregated for each year to determine whether the MSA or non-MSA meets the Fossil Fuel Employment threshold of 0.17 percent. Section 3.02 of this notice modifies the Fossil Fuel Employment rate determination by adding two NAICS codes to the table provided in section 3.03(2) of Notice 2023-29.
