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 (ODOC) 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 12 to 18 months before the rebate programs are available to the Oklahoma public (Winter 2025 – Summer 2025). 

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.

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

ODOC 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). ODOC 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. ODOC defines rural residents according to the U.S. Census parameters.

The Oklahoma Department of Commerce will first request a letter of intent. Then those that are approved may move forward with the application process. This process may open-up as early as Spring 2024 or as late as Summer 2024.

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)

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:

  1. Grid Resilience Utility and Industry Grants – 40101(c)**
  2. Smart Grid Grants – Section 40107
  3. 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.
