To submit an application for Office of Energy Efficiency and Renewable Energy(EERE) Small Business Innovation Research (SBIR)/Small Business Technology Transfer (STTR) grant you will need to provide a Letter of Intent (LOI) prior to submitting your full application. 

Submit a Letter of Intent

The U.S. Department of Energy (DOE) requires that you submit an LOI before submitting your full application. Only those applicants who submit an LOI by the due date listed in the funding opportunity announcement (FOA) will be eligible to submit a full application. DOE program managers use LOIs to determine the number of independent scientific and engineering experts that may be required to conduct the application review process. Feedback will only be provided on your LOI if your proposed R&D does not appear to align with the selected topic’s subtopic.

Once topics are published in the FOA, and even after submitting an LOI, you are encouraged to ask the identified DOE topic manager(s) questions. You can ask questions about the published topics up to the day you submit your full application(s).

Get more information on LOI requirements and see a sample LOI.

Submit a Full Application

As noted in Step 1 – Complete Required Registrations, applicants are required to register with Grants.gov. This is because applicants are required to complete a Grants.gov application package to apply for a given funding opportunity. Full applications must be submitted using the forms provided by Grants.gov.
