DOE C-SITE Local Government Energy Grants: 2024 Historical Reference
Historical reference for the U.S. Department of Energy C-SITE competitive grant round, a broad local-government clean-energy implementation FOA that closed in 2024 and was not a dedicated municipal heat grant.
DOE C-SITE Local Government Energy Grants: 2024 Historical Reference
This page records the U.S. Department of Energy’s Communities Sparking Investment in Transformative Energy (C-SITE) Funding Opportunity Announcement, FOA number DE-FOA-0003229. The official source is a DOE Office of State and Community Energy Programs document hosted on Infrastructure eXCHANGE. It is a completed competitive grant round, not an open municipal heat-resilience application.
The original listing presented this as a municipal heat-resilience opportunity worth $8.5 million per city. The official FOA does not support that description. C-SITE was a broad local-government and Tribal clean-energy implementation program. Its eligible project areas included building efficiency and electrification, clean transportation, energy infrastructure upgrades, microgrid development and deployment, renewable energy, workforce development, and resilience hubs. Heat-related work could have been relevant when it was part of a credible clean-energy implementation project, but DOE did not publish this FOA as a dedicated heat-cooling grant with a guaranteed $8.5 million award.
The page is intentionally marked as a historical reference. The official Infrastructure eXCHANGE listing retains the completed FOA and its May 31, 2024 closing date. The DOE materials reviewed for this update do not announce a later C-SITE application round or a new deadline for this opportunity. Do not treat the date below as a deadline that a city can still meet, and do not replace it with a guessed future date.
What the official FOA actually offered
The FOA anticipated approximately $18 million in federal funding, subject to the availability of appropriated funds. DOE expected to make approximately 5 to 20 awards. The stated award range was approximately $900,000 to $3.6 million per award, with an expected performance period of 12 to 36 months. Those figures describe the C-SITE funding announcement, not an award reserved for heat mitigation or cooling infrastructure.
The program’s purpose was to help local governments and federally recognized Indian Tribes implement high-impact clean-energy projects in communities that are often underserved by federal programs. DOE described four broad goals: deliver direct community benefits such as lower energy costs and improved air quality; spark additional local investment and economic development; advance community-identified energy priorities and self-determination; and build capacity and partnerships in local governments and Tribes.
The FOA also offered support beyond the financial award. Selected communities could receive expert technical assistance, peer exchanges, and the opportunity to host a Community Energy Fellow for up to 18 months, depending on availability. That support was intended to help recipients implement an awarded project. It was not a substitute for an open application or a stand-alone planning grant.
Who was eligible in the completed round
Eligible prime applicants were local governments and Tribal governments representing at least one of these community types:
- disadvantaged communities;
- energy communities; or
- small- and medium-sized jurisdictions.
The FOA’s definition of local government was broader than a city hall. It included cities, towns, villages, counties acting for unincorporated communities, special districts, joint powers authorities, municipally or Tribally owned utilities, metropolitan or regional planning organizations, and councils of governments. A potential applicant still had to satisfy the FOA’s definition and submit as an eligible prime applicant; being a public or quasi-public entity by itself was not enough.
The FOA included an eligibility map as an aid, but it also explained what to do when a community was missing or inaccurately categorized. The applicant had to explain in its application why the community met the definitions in the FOA. A city should therefore have prepared a concise eligibility explanation rather than relying on a map label without supporting evidence.
The applicant’s project also had to fit the program’s implementation focus. DOE said projects in visioning and planning stages rather than implementation stages would be considered nonresponsive. A municipality with only a general heat study or an early idea would have needed a different technical-assistance path. A project with a defined scope, implementation partners, procurement path, schedule, and measurable community benefits was a better fit for the competitive award structure.
The cost-share requirement was reduced to 5 percent for this announcement. The FOA allowed the nonfederal share to include staff time, municipal or Tribal budgets, philanthropic funds, and qualifying third-party contributions, including in-kind services that advanced the proposed project. The contribution had to come from a nonfederal source unless otherwise allowed by law. This requirement mattered to budget design: the applicant needed to identify the source and value of the contribution, not simply state that matching support would be found later.
What a heat-related project would have needed to show
The official source does not say that C-SITE funded cooling centers, tree planting, shade structures, or heat-response plans as a separate grant category. A city interested in heat resilience would have needed to connect its proposed work to the FOA’s clean-energy implementation scope and explain the direct benefits for residents and workers.
For example, an existing public building that served as a resilience hub might have combined insulation, efficient lighting, HVAC improvements, and other energy upgrades with reliable public services during extreme heat. That kind of project could be presented as a defined building-efficiency and resilience intervention. The application would still have needed to follow the FOA, including its requirements for implementation, community engagement, budget, schedule, and applicable environmental and historic-preservation reviews.
A proposal centered only on a broad heat-vulnerability assessment would have been a weak match because the FOA said visioning and planning proposals were not of interest for the competitive implementation award. A proposal centered on an uncosted list of cooling ideas would also have needed more definition. The applicant would have needed to identify the facilities or assets, explain the energy approach, identify who would operate and maintain the result, and show how residents would benefit.
Meaningful community engagement was required across the FOA’s project scope. Partnerships were not mandatory, but DOE said it would prioritize clear demonstrated support from community partners and relevant decision-makers. For a heat-related project, useful evidence could have included support from public-health staff, housing or community organizations, facility operators, workforce partners, or residents who would use the improved assets. Support letters alone would not replace a coherent project plan, but they could show that the intervention addressed a community-identified need.
The completed application process
The following steps describe how applicants were instructed to apply to this closed FOA. They are retained for archival and preparation purposes only; they are not instructions that reopen the round.
- Read the complete FOA, including Modifications 0001 and 0002, and confirm that the prime applicant, community, project type, and implementation stage met the stated requirements.
- Register the organization in Infrastructure eXCHANGE, the DOE application portal, and use that portal for the full application.
- Register in the System for Award Management (SAM) and obtain a Unique Entity Identifier (UEI) before submission. The FOA warned that entity validation could take time and required an active SAM registration when an application or award was under consideration.
- Register in FedConnect so an eligible entity could receive and acknowledge an award if selected.
- Register in Grants.gov to receive automatic notices when amendments were made to the FOA.
- Prepare the required Application for Federal Funding (SF-424), summary slide, project narrative template, and budget information (SF-424A). Include an indirect-rate agreement or rate proposal when applicable.
- Include the Disclosure of Lobbying Activities (SF-LLL), compliance and assurances, and any DOE work proposal or contracting-officer authorization required for a participating federal research and development center.
- Prepare the project schedule, milestones, budget and spend-plan explanation, capacity-building statement, resumes for the project manager and senior or key personnel, and any applicable letters of commitment or support. Third-party cost-share letters needed to identify the organization, contribution amount or value, and whether the contribution was cash or in-kind.
- Submit one full application for the entity through Infrastructure eXCHANGE by 5:00 p.m. Eastern Time on May 31, 2024. The FOA limited an entity to one full application, although an organization could collaborate on another application as a partner or subrecipient.
The FOA also provided for replies to reviewer comments after the full application deadline. That later step was for applicants in the completed review process, not a second opportunity to submit a new application. Selection notifications and award negotiations were described as expected follow-on stages, but they do not create a new application window.
Materials worth keeping for a future announcement
Even though this FOA is closed, a municipality can preserve useful work without claiming that a new C-SITE round exists. Keep a project file that identifies the target facilities or service area, the heat and energy problem, the proposed clean-energy measures, the implementation owner, the maintenance plan, the procurement route, and the expected resident benefits.
The budget should separate federal funds, the 5 percent nonfederal share used by this completed FOA, and any additional local or third-party contribution. Keep the assumptions behind labor, equipment, construction, design, permits, outreach, and maintenance visible. If the project relies on partner support, record the partner’s role and the evidence that the support is available.
The narrative should also preserve a clear baseline and a small set of measurable outcomes. Examples include energy use in participating buildings, operating costs, hours of reliable public service during heat events, facility accessibility, resident use, or workforce participation. These are preparation examples, not promises that a future DOE notice will use the same measures. Any future application must follow the successor notice rather than copying the closed FOA.
