The Treasury Department and IRS also announced that approximately 325 megawatts of available capacity will rollover to the 2024 program year. This will add to the annual 1.8 gigawatts of capacity for a total of 2.125 gigawatts of capacity available in 2024. The 2.125 gigawatts of capacity for the 2024 round will be allocated as follows by category:

  • 800 MW for projects located in low-income communities
  • 200 MW for projects located on Indian land
  • 225 MW for projects located on qualified low-income residential building projects
  • 900 MW for projects that are qualified low-income economic benefit projects

All applications submitted within the first 30 days (by June 27, 2024) will be treated as submitted on the same date and at the same time. Following the initial 30-day period, the Department of Energy (DOE) will continue to accept applications on a rolling basis.


The program, established under H.R. 5376 (commonly called the “Inflation Reduction Act of 2022” (IRA)), provides an increase of 10% or 20% to the investment tax credit for qualified solar or wind facilities in low-income communities.

The Treasury Department and IRS launched the program in February 2023 under Notice 2023-17, which provided initial program guidance for potential applicants for allocations of calendar year 2023 capacity limitation. Read TaxNewsFlash
