Key Point Summary

To follow developments: DOE informational webinar is scheduled for June 27, 2023. 

Note: Information is summarized IRS documents that are linked from notices on May 31, 2023 and February 13, 2023.  It is current as of June 20, 2023.

Section 48C: Advanced Energy Project Credit

Through the Inflation Reduction Act (IRA), $10 billion is allocated to investment tax credits under Section 48C for advanced energy projects.  Each project is eligible for a 30% investment tax credit (subject to meeting certain prevailing wage and apprenticeship requirements) for project costs for tangible property, not including the building or its structural components. 

Through subsequent guidance, most notably IRS Notice 2023-44 on May 31st, advanced energy projects fit into one of three categories:

  1. Clean Energy Manufacturing and Recycling Projects (9 Subcategories)
  2. Greenhouse Gas Emissions Projects
  3. Critical Materials Projects

To be eligible for tax credits, the project may not be placed in service prior to award allocation. 

DOE will evaluate and recommend projects based on four (4) technical review criteria:

  1. Commercial viability
  2. Greenhouse gas emissions impacts
  3. Strengthening US supply chains and domestic manufacturing for a net-zero economy
  4. Workforce and community engagement

Program Timing and Process

48C will have at least two rounds of allocation, with Round 1 closing for Concept Papers on July 31, 2023.  Round 2 has not yet been announced, but is anticipated to likely be after March 31, 2024, which is the deadline for awards of Round 1 allocations.

In Round 1, the IRS anticipates awarding up to $4 billion of 48C credits with approximately $1.6 billion being allocated to projects in Energy Communities Census tracts. 

To apply for the credit is a multi-step process, with feedback from the Department of Energy (DOE) along the way.

Step 1: Concept Paper

By July 31st, interested applicants must submit a concept paper through the DOE exCHANGE Portal that outlines requested information on the proposed project.  The DOE will perform a review of the concept paper and send the applicant a letter either encouraging or discouraging the submission of a 48C application.

Step 2: Application

Whether the DOE provides encouragement or discouragement for the concept paper, applicant may still complete the application, although projects that are discouraged from applying are less likely to be allocated funds.  The application is a more detailed project plan that addresses feasibility and technical aspects of the project.  The DOE will review each application and provide recommendations to the IRS regarding acceptance or rejection of each application.  The IRS will approve projects for the tax credit and sends a letter of notification to the applicant.

The IRS will make all Round 1 allocation decisions by March 31, 2024. 

Step 3 and Beyond

After receiving an allocation of the credit from the IRS, the approved application (taxpayer) has two (2) years to notify DOE that the certification requirements have been met by submitting this through the exCHANGE portal.  The IRS issues a Certification Letter.  Within two (2) years of receiving the Certification Letter, the taxpayer notifies DOE the project has been placed into service, and then can claim the tax credit on that year’s return.

Categories of Eligible Projects

There is a host of eligible projects in three categories (and their subcategories).

Clean Energy Manufacturing and Recycling Projects (9 Subcategories)

A qualifying advanced energy project in this category re-equips, expands or establishes an industrial or manufacturing facility for the production or recycling of specified advanced energy property:

Greenhouse Gas Emissions (GHS) Reduction Projects (5 Subcategories)

A qualifying advanced energy project in this category re-equips an industrial or manufacturing facility, including in energy-intensive manufacturing sections, such as cement, iron, steel, aluminum, chemicals and other sectors, with equipment to reduce greenhouse gas emissions by at least 20 percent through installation of one or more the following:

Critical Materials

A qualifying advanced energy project in this category re-equips, expands or establishes an industrial facility for the processing, refining, or recycling of critical materials as defined by the Energy Act of 2020.  For Round 1, critical materials consist of:

DOE Review Criteria

Each of the three project categories (with subcategories) has Concept Paper and Application requirements that are divided into four review criteria.

  1. Commercial viability
    • Identifying projects with the lowest levelized cost, shortest time frame for completion, lowest risk, and highest impact
  2. Greenhouse gas emissions impacts
    • Identifying projects with the greatest net impacts in avoiding or reducing anthropogenic emissions of GHG
  3. Strengthening US supply chains and domestic manufacturing for a net-zero economy
    • Identifying projects with the greatest impact on domestic job creation and potential for technological innovation and commercial deployment
  4. Workforce and community engagement
    • Identifying projects with the workforce and community support that will lead to domestic job creation, reduce barriers that may otherwise increase project completion time, and have an impact on avoiding or reducing local pollution, including non-greenhouse gas air pollution. 

Energy Communities Census Tracts

DOE will allocate specific funds (at least approximately $1.6 billion of the $4 billion in funds in Round 1) to Energy Communities as published on by the IRS Energy Community Census Tract List


The Inflation Reduction Act’s Section 48C $10 billion tax credit presents a significant opportunity for businesses to advance sustainable practices and contribute to the transition towards a net-zero economy. With the first round of funding closing on July 31, 2023, interested applicants must submit a Concept Paper outlining their proposed project. By aligning projects with the criteria outlined by the DOE, businesses can benefit from the investment tax credits up to 30%. 

A Final Thought: Pick the low hanging fruit…and plant the seeds.

After your company saves a few million dollars on a project that your ESG or shareholder goals required through this tax credit, invest some of that savings into a life creating project.  I often say that the Inflation Reduction Act creates an abundance of low hanging fruit – tax incentives that fund projects that need to happen anyway that have great ROI – and we should pick the fruit. 

After you pick the fruit, plant the seeds by investing in a project to create life on your property and business.  What land or water do you steward, and how can you create life through your next decision?
