Frequently Asked Questions
If I already purchased an appliance, can I be reimbursed later?
Since no guidance has been released, the answer is likely no. We do not yet know all the standards the equipment must meet or other requirements. Furthermore, households must be income qualified. The best way to ensure a possibility of reimbursement is to wait until guidance comes out and the Oklahoma Department of Commerce has designed the program according to federal requirements.
When will the rebate funds be available?
The Oklahoma Department of Commerce (Commerce) does not have an exact answer to this question yet. Guidance for program implementation was released by the U.S. Department of Energy in July 2023, but applications for funding are not due until January 2025. Due to the complex nature of this program, quality development will take time. It will be approximately 18 – 24 months before the rebate programs are available to the Oklahoma public (Winter 2025 – Summer 2026).
Requirements for Loans + Grants
Energy efficiency measures must be identified through an energy assessment performed consistent with industry best practices and standards and lead to a reduction in energy usage.
For questions about the program, contact Amanda Marcott-Thottunkal at 405-815-5374 or amanda.marcott-thottunkal@okcommerce.gov.
Solar for All
Solar for All, a program of the U.S. EPA, will tackle the financial and non-financial barriers that limit the ability of low-income and disadvantaged communities across the country to benefit from the rapid growth in distributed solar capacity.
The Oklahoma Department of Commerce State Energy Office is pleased to announce a request for information is now available for the new Solar for All competitive funding that Oklahoma will be applying for from the United States Environmental Protection Agency (U.S. EPA). The information gathered from the RFI will be used to inform future solicitation(s) and the grant application. The RFI can be found here on the Commerce website.
Grid Resiliency Grant
Updated 11/04/2025: The Oklahoma Department of Commerce is expected to release a Pre Concept Proposal Form submission process early 2026. No funding opportunities have yet to be released.
Commerce will make grant awards available to Eligible Entities through a competitive grant process to complete allowable resiliency measures in their service area. There will be two types of Eligible Entities – a general type and a small utility company (20,000 customers or fewer of a public utility). Commerce will give preference to Eligible Entities that directly provide electricity to the public and those who are considered a public utility or independent electric cooperative. Priority will also be given to Eligible Entities who serve rural Oklahoma residents. Commerce defines rural residents according to the U.S. Census parameters.

In September 2023, the Department of Energy awarded $15,162,373 to Oklahoma via the Grid Resilience State and Tribal Formula Grants program, which is supported by the Bipartisan Infrastructure Law.
State awards are based on a formula that includes factors such as population size, land area, probability and severity of disruptive events, and a locality’s historical expenditures on mitigation efforts.
The Oklahoma Department of Commerce is currently working diligently on an implantation plan to get this program up and running. It could be another 3-6 months before the program is operational. There will be a competitive process for qualified applicants to apply for the funding.
You can sign up for our energy programs email list on this page to receive notifications for the application process and other important updates as they become available. All updates will be posted on the website.
Grid Resilience and Innovation Partnerships (GRIP)
Topic Area 3 Section 40103(b)– Grid Innovation Program. This RFI is open December 14, 2023 – December 19, 2023.
As part of the Bipartisan Infrastructure Law, the U.S. Department of Energy (DOE) Grid Deployment Office is administering a $10.5 billion Grid Resilience and Innovation Partnerships (GRIP) Program to enhance grid flexibility and improve the resilience of the power system against growing threats of extreme weather. There are three topic areas under GRIP:
- Grid Resilience Utility and Industry Grants – 40101(c)**
- Smart Grid Grants – Section 40107
- Grid Innovation Program – Section 40103 (b)
The Oklahoma Department of Commerce (Commerce) is issuing this Request for Information (RFI) to determine whether or not there are any entities (public, private or nonprofit) interested in partnering with Commerce on Topic Area 3 – Grid Innovation, Section 40103 (b), or whether there are other public entities in Oklahoma already planning to submit a concept paper, which is due January 12, 2024.
Revolving Loan Funds
The Oklahoma Department of Commerce (Commerce), Community Development department, on behalf of the Oklahoma State Energy Office (SEO), is seeking information from Oklahoma lenders, banking institutions and subject matter experts, to help develop a new Oklahoma Energy Efficiency Co-Lending Fund for the State of Oklahoma. Commerce has received an allocation of $7,592,300 from the U.S. Department of Energy (DOE) under its Energy Efficiency Revolving Loan Fund Capitalization Grant Program, established by Section 40502 of the Infrastructure Investment and Jobs Act, which will provide the funding for the new program. In the event the program is successful, the SEO will consider expanding the loan program to additional markets and adding additional funds remaining from the Stripper Well Restitution Program, Exxon Restitution Program and other loan funding awarded during the American Recovery and Reinvestment Act of 2009. To see the Request for Information, please visit the link below. The RFI is open December 19, 2023, until February 29, 2024.
Energy Efficiency Conservation Block Grant
U.S. Department of Energy (DOE) awarded Oklahoma $2,065,790, in Energy Efficiency and Conservation Block Grant (EECBG) program formula funding. Oklahoma is among over 2,700 eligible states, territories, local governments and tribes to receive EECBG funding. This vital initiative aims to reduce energy use, decrease fossil fuel emissions and enhance energy efficiency statewide.
The Oklahoma Department of Commerce (Commerce) is allocating $169,019.00 over two years to each of the state’s 11 Councils of Government (COG) to assist rural governments in developing comprehensive strategic energy plans.
Utilizing a professional energy planner, these carefully developed plans will outline a strategic vision and long-term goals for managing and optimizing energy resources within a designated community. They will serve as a roadmap for making informed decisions about the production, distribution and consumption of energy resources -whether it be a plan for reducing carbon emissions, minimizing energy waste in local government buildings or increasing the resiliency of the local building codes to withstand environmental disasters. Priority will be given to local governments serving disadvantaged rural communities in Oklahoma.
The EECBG program is a critical step toward ensuring that Oklahoma remains a leader in promoting energy efficiency, reducing emissions and securing a sustainable future for all Oklahomans. In the future, Commerce will collaborate with communities that have developed an Energy Strategic Plan to secure financing for their prioritized needs.
For more information about the program and its impact on Oklahoma communities, please contact Amanda Marcott-Thottunkal at Amanda.Marcott-Thottunkal@okcommerce.gov or subscribe to receive our energy programs email updates and track the impact of these funds.
