APPENDIX B DOE APPLICATION PROCESS

I. DOE Review Process

A two-stage technical evaluation process will be used for submissions:

  • Stage 1 – Concept Paper

  • Stage 2 – § 48C(e) Application

A. Concept Paper

The first stage requires taxpayers to submit concept papers describing the proposed project. Concept papers will be evaluated against criteria that may include eligibility requirements, definitions for qualifying advanced energy projects, reasonable expectation of commercial viability, and other factors described in the additional § 48C(e) program guidance. Following this preliminary review, taxpayers will receive a letter either encouraging them to submit a § 48C(e) application or discouraging them from submitting a § 48C(e) application. DOE will begin accepting concept papers when the additional § 48C(e) program guidance is issued on May 31, 2023, and concept papers must be submitted to DOE no later than July 31, 2023.

A taxpayer that receives a discouragement letter may still submit a § 48C(e) application in accordance with the § 48C(e) program guidance. Receiving a discouragement letter in response to a submitted concept paper does not disqualify a taxpayer from submitting a § 48C(e) application but represents DOE’s feedback that the project, as proposed, is unlikely to receive a recommendation based on the information provided in the concept paper.

B. § 48C(e) Application

The second evaluation stage will consist of a review of § 48C(e) applications submitted after the concept paper stage. Taxpayers may not submit § 48C(e) applications unless they submitted concept papers by the specified deadline.

DOE will review applications for DOE recommendation for compliance to determine that (1) the application meets the eligibility requirements, (2) the information required by the additional § 48C(e) program guidance has been submitted, (3) the taxpayer filed a timely concept paper, and (4) all mandatory requirements of the additional § 48C(e) program guidance are satisfied. The review will also include a thorough, consistent, and objective examination of applications for DOE recommendation based on technical review criteria and program policy factors outlined in the additional § 48C(e) program guidance.

II. Application Evaluation Information

A. Technical Review Criteria

Applications for DOE recommendation will be evaluated based on technical review criteria to be described in the additional § 48C(e) program guidance. These criteria will include selection criteria described in § 48C(d)(3) and additional criteria that further the goals of the program.

As part of the technical review criteria to be described in the additional § 48C(e) program guidance, DOE anticipates evaluating applications for DOE recommendation based on the net impact of the qualifying project in avoiding or reducing greenhouse gases emissions, as described in the additional § 48C(e) program guidance. DOE also anticipates evaluating applications for DOE recom­ mendation based on the community benefits of the proposed qualifying advanced energy projects, which may include community and labor engagement and commitment to high quality and accessible jobs and workforce pathways.

B. Program Policy Factors

In addition to technical review criteria, DOE may consider one or more policy factors in determining which applications for DOE recommendation submitted during Round 1 of the § 48C(e) program to recommend to the IRS for certification.

To achieve maximum benefits to strengthen U.S. industrial competitiveness and clean energy supply chains as well as to promote high quality jobs and community benefits, DOE may consider giving priority to qualifying advanced energy projects not eligible for support from other DOE financial assistance programs funded by the Infrastructure Investment and Jobs Act (Public Law 117-58) or the Inflation Reduction Act of 2022 (Public Law 117-169).

March 6, 2023 520 Bulletin No. 2023–10

In some cases, benefits towards the program’s goals may be enhanced if a project receiving a credit under § 48C also receives com­ plementary assistance from other programs. For taxpayers seeking assistance from other programs for the same proposed qualifying advanced energy project, DOE may consider whether the application for DOE recommendation sufficiently justifies the need for and benefits of receiving assistance from multiple programs. Complementary assistance may also affect the tax treatment of property for which a taxpayer receives an allocation under the § 48C(e) program.

C. Strengthening Secure, Domestic, Clean Energy Supply Chains

To help build more resilient, diverse, and secure U.S. clean energy supply chains, DOE may consider whether proposed projects address specific gaps, vulnerabilities, or risks in the domestic production of clean energy products. The additional § 48C(e) program guidance will indicate specific priority technologies that would address these gaps, vulnerabilities, and risks to relevant domestic supply chains.

To further ensure the § 48C(e) program supports these goals to the greatest extent possible, DOE may conduct a review to determine if an applicant has a connection with a foreign country of risk that could frustrate the achievement of these goals. To ensure trans­ parency of foreign connections, DOE anticipates requiring applicants to provide certain information regarding, for example, board membership, ownership structure, and foreign relationships, as well as sources of, and any plans to export, critical minerals.

III. Submission and Registration Requirements for DOE Recommendation Process

This section describes DOE’s submission and registration requirements for applicants. An application for DOE recommendation will not be considered in Round 1 of the § 48C(e) program unless the concept paper is received by the concept paper deadline, and the § 48C(e) application is received by the end of the application period.
