Port Infrastructure Development Program (PIDP)

Federal Agency


Maritime Administration


To improve facilities within, or outside of and directly related to operations of or an intermodal connection to, coastal seaports, inland river ports, and Great Lakes ports.

Applicant and/or Project Eligibility Requirements

Eligible applicants include a port authority, a commission or its subdivision or agent under existing authority, a State or political subdivision of a State or local government, a Tribal government, a public agency or publicly-chartered authority established by one or more States, a special purpose district with a transportation function, a multistate or multijurisdictional group of entities, or a lead entity described above jointly with a private entity or group of private entities.

Decarbonization Considerations

PIDP grants can improve port infrastructure, including intermodal connections, or reduce or eliminate pollutants and greenhouse gas emission. This program focuses on infrastructure enhancements that directly impact port operations. Consider projects that support freight and port vehicle fleet electrification, port resiliency with battery storage, and major efficiency retrofits to reduce the energy intensity of port operations. According to the 2023 NOFO, DOT seeks to fund projects that reduce emissions in the transportation sector, enable the deployment of clean energy including offshore wind, incorporate evidence-based climate resilience measures and features, reduce the lifecycle greenhouse gas emissions from the project materials, and avoid adverse environmental impacts, to air or water quality, wetlands, and endangered species, and address the disproportionate negative environmental impacts of transportation on disadvantaged communities.

Equity Considerations

PIDP program priorities have been updated to include a focus on improving racial equity and access to opportunity, mitigating or reducing the effects of climate change in addition to the goals of improving the safety, efficiency and reliability of the movement of goods. Consider clean energy and transportation upgrades that would reduce localized emissions and impact to neighboring communities.

Helpful Tips

THE FY 2023 NOFO includes updated selection considerations pertaining to: Climate Change and Sustainability; Equity and Justice40; and Workforce Development, Job Quality, and Wealth Creation. Applicants who are planning to re-apply using materials prepared for prior competitions should ensure that their FY 2023 PIDP application fully addresses the statutory merit criteria and selection considerations in the FY 2023 NOFO and that all relevant information is up to date. For funding awarded under the BIL, there is no minimum award size. For all projects funded under the FY 2023 Appropriations Act, the minimum PIDP award size is $1 million. Therefore, to compete for the full amount of funding available, funding requests should be at least $1 million. No more than 25% of the available funds can be awarded for projects in any one State. At least $187,203,512 is reserved for grants to coastal seaports or Great Lakes ports. 25% of the available funds is reserved for small projects at small ports.

Other Notes

In FY2023, the Bipartisan Infrastructure Law (BIL) appropriated $450 million to the PIDP. An additional $212,203,512 was made available to the program under the FY2023 Consolidated Appropriations Act, resulting in a total of $662,203,512 in FY 2023 PIDP grant funding.
