*Projects with a maximum net output of less than 1 megawatt or which commence construction prior to the date of enactment are NOT subject to labor requirements and are eligible for the "bonus credit" amount (the statutory credit amount). However, projects with a
net maximum output of at least 1 megawatt and that begin construction on or after the date of enactment must satisfy new labor requirements (prevailing wage and apprenticeship) to be eligible for the "bonus credit" amount. Failure for these projects to satisfy the labor
requirements reduces the statutory credit amount to the "base credit" amount (20% of the statutory credit amount).

**Projects NOT subject to labor requirements (maximum net output of less than 1 megawatt or which commence construction prior to the date of enactment) that are placed in service after the date of enactment and certified as having satisfied certain domestic content
requirements qualify for a 10 percentage point increase (10%) if the project satisfies both labor requirements (prevailing wage and apprenticeship), or a 2 percentage point increase (2%) for satisfying only one of the two labor requirements (prevailing wage or
apprenticeship). Projects subject to labor requirements (maximum net output of at least 1 megawatt and that begin construction on or after the date of enactment) and certified as having satisfied certain domestic content requirements qualify for a 10 percentage point
increase (10%) if the project satisfies both labor requirements (prevailing wage and apprenticeship) and a 2 percentage point increase (2%) if the project fails to satisfy both labor requirements.

***Domestic content requirements are "phased-in" for purposes of determining the direct pay percentage. Projects that begin construction before January 1, 2024 are NOT subject to domestic content requirements to qualify for 100% direct pay. Projects that begin
construction during calendar 2024 and fail domestic content requirements are eligible for direct pay at 90% of the "base credit" or "bonus credit" amount otherwise available. Projects that begin construction during calendar 2025 and fail domestic content requirements
are eligible for direct pay at 85%. And projects that begin construction after 2025 and fail to satisfy domestic content requirements are ineligible for direct pay (direct pay percentage equals 0%).

*Projects with a maximum net output of less than 1 megawatt or which commence construction prior to the date of enactment are NOT subject to labor requirements and are eligible for the "bonus credit" amount (the statutory credit amount). However, projects with a
net maximum output of at least 1 megawatt and that begin construction on or after the date of enactment must satisfy new labor requirements (prevailing wage and apprenticeship) to be eligible for the "bonus credit" amount. Failure for these projects to satisfy the labor
requirements reduces the statutory credit amount to the "base credit" amount (20% of the statutory credit amount).

**Projects NOT subject to labor requirements (maximum net output of less than 1 megawatt or which commence construction prior to the date of enactment) that are placed in service after the date of enactment and certified as having satisfied certain domestic content
requirements qualify for a 10 percentage point increase (10%) if the project satisfies both labor requirements (prevailing wage and apprenticeship), or a 2 percentage point increase (2%) for satisfying only one of the two labor requirements (prevailing wage or
apprenticeship). Projects subject to labor requirements (maximum net output of at least 1 megawatt and that begin construction on or after the date of enactment) and certified as having satisfied certain domestic content requirements qualify for a 10 percentage point
increase (10%) if the project satisfies both labor requirements (prevailing wage and apprenticeship) and a 2 percentage point increase (2%) if the project fails to satisfy both labor requirements.

***Domestic content requirements are "phased-in" for purposes of determining the direct pay percentage. Projects that begin construction before January 1, 2024 are NOT subject to domestic content requirements to qualify for 100% direct pay. Projects that begin
construction during calendar 2024 and fail domestic content requirements are eligible for direct pay at 90% of the "base credit" or "bonus credit" amount otherwise available. Projects that begin construction during calendar 2025 and fail domestic content requirements
are eligible for direct pay at 85%. And projects that begin construction after 2025 and fail to satisfy domestic content requirements are ineligible for direct pay (direct pay percentage equals 0%).

*Projects with a maximum net output of less than 1 megawatt or which commence construction prior to the date of enactment are NOT subject to labor requirements and are eligible for the "bonus credit" amount (the statutory credit amount). However, projects with a
net maximum output of at least 1 megawatt and that begin construction on or after the date of enactment must satisfy new labor requirements (prevailing wage and apprenticeship) to be eligible for the "bonus credit" amount. Failure for these projects to satisfy the labor
requirements reduces the statutory credit amount to the "base credit" amount (20% of the statutory credit amount).

**Projects NOT subject to labor requirements (maximum net output of less than 1 megawatt or which commence construction prior to the date of enactment) that are placed in service after the date of enactment and certified as having satisfied certain domestic content
requirements qualify for a 10 percentage point increase (10%) if the project satisfies both labor requirements (prevailing wage and apprenticeship), or a 2 percentage point increase (2%) for satisfying only one of the two labor requirements (prevailing wage or
apprenticeship). Projects subject to labor requirements (maximum net output of at least 1 megawatt and that begin construction on or after the date of enactment) and certified as having satisfied certain domestic content requirements qualify for a 10 percentage point
increase (10%) if the project satisfies both labor requirements (prevailing wage and apprenticeship) and a 2 percentage point increase (2%) if the project fails to satisfy both labor requirements.

***Domestic content requirements are "phased-in" for purposes of determining the direct pay percentage. Projects that begin construction before January 1, 2024 are NOT subject to domestic content requirements to qualify for 100% direct pay. Projects that begin
construction during calendar 2024 and fail domestic content requirements are eligible for direct pay at 90% of the "base credit" or "bonus credit" amount otherwise available. Projects that begin construction during calendar 2025 and fail domestic content requirements
are eligible for direct pay at 85%. And projects that begin construction after 2025 and fail to satisfy domestic content requirements are ineligible for direct pay (direct pay percentage equals 0%).

*Projects with a maximum net output of less than 1 megawatt or which commence construction prior to the date of enactment are NOT subject to labor requirements and are eligible for the "bonus credit" amount (the statutory credit amount). However, projects with a
net maximum output of at least 1 megawatt and that begin construction on or after the date of enactment must satisfy new labor requirements (prevailing wage and apprenticeship) to be eligible for the "bonus credit" amount. Failure for these projects to satisfy the labor
requirements reduces the statutory credit amount to the "base credit" amount (20% of the statutory credit amount).

**Projects NOT subject to labor requirements (maximum net output of less than 1 megawatt or which commence construction prior to the date of enactment) that are placed in service after the date of enactment and certified as having satisfied certain domestic content
requirements qualify for a 10 percentage point increase (10%) if the project satisfies both labor requirements (prevailing wage and apprenticeship), or a 2 percentage point increase (2%) for satisfying only one of the two labor requirements (prevailing wage or
apprenticeship). Projects subject to labor requirements (maximum net output of at least 1 megawatt and that begin construction on or after the date of enactment) and certified as having satisfied certain domestic content requirements qualify for a 10 percentage point
increase (10%) if the project satisfies both labor requirements (prevailing wage and apprenticeship) and a 2 percentage point increase (2%) if the project fails to satisfy both labor requirements.

***Domestic content requirements are "phased-in" for purposes of determining the direct pay percentage. Projects that begin construction before January 1, 2024 are NOT subject to domestic content requirements to qualify for 100% direct pay. Projects that begin
construction during calendar 2024 and fail domestic content requirements are eligible for direct pay at 90% of the "base credit" or "bonus credit" amount otherwise available. Projects that begin construction during calendar 2025 and fail domestic content requirements
are eligible for direct pay at 85%. And projects that begin construction after 2025 and fail to satisfy domestic content requirements are ineligible for direct pay (direct pay percentage equals 0%).

*Projects with a maximum net output of less than 1 megawatt or which commence construction prior to the date of enactment are NOT subject to labor requirements and are eligible for the "bonus credit" amount (the statutory credit amount). However, projects with a
net maximum output of at least 1 megawatt and that begin construction on or after the date of enactment must satisfy new labor requirements (prevailing wage and apprenticeship) to be eligible for the "bonus credit" amount. Failure for these projects to satisfy the labor
requirements reduces the statutory credit amount to the "base credit" amount (20% of the statutory credit amount).

**Projects NOT subject to labor requirements (maximum net output of less than 1 megawatt or which commence construction prior to the date of enactment) that are placed in service after the date of enactment and certified as having satisfied certain domestic content
requirements qualify for a 10 percentage point increase (10%) if the project satisfies both labor requirements (prevailing wage and apprenticeship), or a 2 percentage point increase (2%) for satisfying only one of the two labor requirements (prevailing wage or
apprenticeship). Projects subject to labor requirements (maximum net output of at least 1 megawatt and that begin construction on or after the date of enactment) and certified as having satisfied certain domestic content requirements qualify for a 10 percentage point
increase (10%) if the project satisfies both labor requirements (prevailing wage and apprenticeship) and a 2 percentage point increase (2%) if the project fails to satisfy both labor requirements.

***Domestic content requirements are "phased-in" for purposes of determining the direct pay percentage. Projects that begin construction before January 1, 2024 are NOT subject to domestic content requirements to qualify for 100% direct pay. Projects that begin
construction during calendar 2024 and fail domestic content requirements are eligible for direct pay at 90% of the "base credit" or "bonus credit" amount otherwise available. Projects that begin construction during calendar 2025 and fail domestic content requirements
are eligible for direct pay at 85%. And projects that begin construction after 2025 and fail to satisfy domestic content requirements are ineligible for direct pay (direct pay percentage equals 0%).

*Projects with a maximum net output of less than 1 megawatt or which commence construction prior to the date of enactment are NOT subject to labor requirements and are eligible for the "bonus credit" amount (the inflation adjusted statutory credit amount).
However, projects with a net maximum output of at least 1 megawatt and that begin construction on or after the date of enactment must satisfy new labor requirements (prevailing wage and apprenticeship) to be eligible for the "bonus credit" amount. Failure for these
projects to satisfy the labor requirements reduces the statutory credit amount to the "base credit" amount (20% of the inflation adjusted statutory credit amount).

**Projects placed in service after the date of enactment and certified as having satisfied certain domestic content requirements qualify for a 10% increase (110%) in the "base credit" or "bonus credit" amount otherwise determined after considering compliance with
applicable labor requirements.

***Domestic content requirements are "phased-in" for purposes of determining the direct pay percentage. Projects that begin construction before January 1, 2024 are NOT subject to domestic content requirements to qualify for 100% direct pay. Projects that begin
construction during calendar 2024 and fail domestic content requirements are eligible for direct pay at 90% of the "base credit" or "bonus credit" amount otherwise available. Projects that begin construction during calendar 2025 and fail domestic content requirements
are eligible for direct pay at 85%. And projects that begin construction after 2025 and fail to satisfy domestic content requirements are ineligible for direct pay (direct pay percentage equals 0%).

projects to satisfy the labor requirements reduces the statutory credit amount to the "base credit" amount (20% of the inflation adjusted statutory credit amount).

**Projects placed in service after the date of enactment and certified as having satisfied certain domestic content requirements qualify for a 10% increase (110%) in the "base credit" or "bonus credit" amount otherwise determined after considering compliance with
applicable labor requirements.

***Domestic content requirements are "phased-in" for purposes of determining the direct pay percentage. Projects that begin construction before January 1, 2024 are NOT subject to domestic content requirements to qualify for 100% direct pay. Projects that begin
construction during calendar 2024 and fail domestic content requirements are eligible for direct pay at 90% of the "base credit" or "bonus credit" amount otherwise available. Projects that begin construction during calendar 2025 and fail domestic content requirements
are eligible for direct pay at 85%. And projects that begin construction after 2025 and fail to satisfy domestic content requirements are ineligible for direct pay (direct pay percentage equals 0%).

Begun construction background

    Under current law, a taxpayer may claim 60 percent of the value of PTCs or the 18% ITC in lieu of PTC on a
    new qualified wind facility or 26% ITC on new solar energy property only if construction of the facility
    begins before January 1, 2024 (the Begun Construction Requirement) for solar and January 1, 2022 for
    wind, respectively
    • The full credit amounts (100 percent of the value of PTCs or the 30% ITC) were available if construction on
      a wind facility began before January 1, 2017
    • The full credit amount (30% ITC) was available if construction on solar energy property began before
      January 1, 2020 (and placed in service before January 1, 2026)
    American Taxpayer Relief Act of 2012 was enacted January 2, 2013
    • Changed eligibility for certain PTC and ITC in lieu of PTC technologies from a “placed-in-service” date
      requirement to a requirement that a facility must have “begun construction” by a certain deadline
    • Based on recent American Recovery and Reinvestment Act section 1603 Treasury Grant Program
      implementation
    Consolidated Appropriations Act of 2021 enacted on December 27, 2020, provided the current extension

Begun Construction Rules
First Prong: Beginning of Construction

Copyright © 2021 Deloitte Development LLC. All rights reserved.   2021 Deloitte Renewable Energy Seminar   25
Investment tax credit (ITC) and production tax credit (PTC)

Prong 1 – Begun Construction Requirement
The IRS provides two methods for taxpayers to establish the beginning of construction to claim the section 45 PTC or
section 48 ITC.
1. 5% Safe Harbor – Having paid or incurred at least five percent of the total cost of the depreciable basis of the facility or
   energy property, excluding land and property not integral to the facility. Integral part means all property used directly in
   the production of electricity from the renewable resource (a qualifying activity) and all property necessary for the
   completeness of the activity.
2. Physical Work Test – Starting physical work of a significant nature (“PWSN”) onsite or offsite related to a qualified
   facility or energy property. Work may be performed by a third party on behalf of a taxpayer (i.e., through a vendor). The
   test focuses on the nature of work performed, not the amount or the cost paid or incurred. PWSN does not include
   preliminary activities, such as designing, research, environmental studies, or removal of existing foundations or work to
   produce property that is existing inventory or is normally held in inventory by a vendor.

Physical work test
Facility and Energy Property Defined
A facility or energy property generally include all components of property that function interdependently
  •     Components of property are functionally interdependent if the placing in service of each of the components is dependent upon
        the placing in service of each of the other components in order to generate electricity
          ▪ Example: On a wind farm, an electricity-generating wind turbine, its tower and supporting pad comprise a single facility
For purposes of determining whether construction of a facility or energy property has begun, multiple facilities that are
operated as part of a single project (or energy properties that are operated as a single energy property) will be treated as a
single facility
Example factors indicating that multiple facilities (or energy properties) are operated as a single project include:

     Binding Written Contract: Any work performed by a contractor is taken into account for PWSN only if it was done under
     a binding written contract with the taxpayer and the contract was in place before the work began

        A contract is binding only if:

        1. The agreement must be enforceable under local law;
        2. The agreement must not limit damages to less than 5% of the total contract price;
        3. The agreement must not be an “option” and will require forfeiture of more than a “nominal” amount (e.g., 5
           percent of the contract price); and
        4. The agreement must not have a substantial modification.

         Other industry considerations:

         1. No clause allowing termination for convenience;
         2. No suspensions; and
         3. No returns or exchanges.
