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).

Grid Resiliency Grant
Updated 02/03/2026: The Oklahoma Department of Commerce is the funding recipient of $24,023,349.00 in U.S. Department of Energy federal funds, with approximately $10 million more in additional funding potentially forthcoming, to develop a program that enables eligible entities to implement grid resilience measures. Eligible entities include electric grid operators, electricity storage operators, electricity generators, transmission owners or operators, distribution providers and fuel suppliers. Through this program, applicants may install a wide range of eligible resilience measures, including—but not limited to—utility pole management, adaptive protection technologies, replacement of aging overhead conductors and underground cables, hardening of power lines, facilities, substations and other system components, as well as fire-resistant technologies and fire prevention systems.
Commerce is hosting a GRID stakeholder meeting on February 18 from 1 to 3:30 p.m., both in person and virtually. Location information is at the bottom of this notification.
Outcome of the Meeting:
- Provide an update to GRID stakeholders on the status of grant development
- Introduce the pre-concept form for review and stakeholder feedback
- Gather input on the application review process and proposed project timeline
Who Should Attend:
This meeting is intended for stakeholders who have an interest in how federal GRID funds are allocated and who are participating solely in a stakeholder advisory capacity.
To ensure a fair and transparent program development process, entities that intend to apply for GRID funding are not eligible to participate in this stakeholder meeting. Organizations and individuals who attend this meeting are prohibited from applying for GRID funds later. At the start of the meeting, Commerce will confirm the stakeholder status of attendees. This applies to both in-person and virtual participation. We appreciate your cooperation in helping Commerce maintain an objective and conflict-free stakeholder process.

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.

- Must provide a cost match of at least $250,000
Eligible Entities include:
- Electric Grid Operators
- Electricity Storage Operators
- Electricity Generators
- Transmission Owners or Operators
- Distribution provider, and
- Fuel suppliers
Eligible Resilience Measures include:
- weatherization technologies and equipment
- fire-resistant technologies and fire prevention systems
- monitoring and control technologies
- utility pole management
- the relocation of power lines or the reconductoring of power lines with low-sag, advanced conductors
- vegetation and fuel-load management
- the use or construction of distributed energy resources for enhancing system adaptive capacity during disruptive events, including microgrids and battery-storage subcomponents
- adaptive protection technologies
- advanced modeling technologies
- hardening of power lines, facilities, substations, of other systems
- the replacement of old overhead conductors and underground cables

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.
