Single-Family Energy Rebates: Idaho
Rebates are available for qualified installations of energy-efficient equipment.
Expiration notice: Effective January 1, 2027, offerings in Idaho gas-powered homes are ending. Eligible projects must be completed by December 31, 2026. Applications and documentation must be received no later than January 15, 2027.
This change is happening because Idaho rules require energy-efficiency programs to provide enough savings to justify the cost of the program. At current natural gas prices, these Idaho natural gas rebate and incentive programs no longer meet that standard.
More information, including an FAQ, is available further down on this page.

Avista Idaho natural gas energy-efficiency initiatives changing in 2027
Starting January 1, 2027, Avista's Idaho natural gas energy efficiency rebates and incentives for homes and businesses will no longer be available. This change affects rebate and incentive programs only and does not affect Avista's natural gas service.
This change is happening because Idaho rules require energy-efficiency programs to save customers more than they cost to operate. Natural gas prices are currently low enough that the possibility of additional savings from these programs no longer outweigh the cost of offering them.
The change applies to:
- Window and door rebates for single-family and multifamily homes primarily heated with natural gas
- Incentives for furnaces, boilers and water heaters and natural gas commercial foodservice equipment
- Incentives for qualifying site-specific natural gas efficiency projects
What you need to do
To qualify for a current Idaho natural gas energy efficiency rebate or incentive:
- Complete your project by December 31, 2026.
- Make sure Avista receives your complete rebate application and all required paperwork by January 15, 2027.
- For furnaces, boilers and water heaters and natural gas commercial foodservice equipment incentives, work directly with your contractor.
- Applications or documents received after the deadline will not qualify for the current programs.
Frequently Asked Questions
What is changing?
Beginning January 1, 2027, Idaho natural gas energy-efficiency rebates and incentives will no longer be available for new projects.
Why is this happening?
Idaho regulators require energy-efficiency programs to demonstrate that the savings they provide to customers are greater than the cost of offering the programs. At current natural gas prices, these programs no longer meet that standard.
Can I still apply for a rebate or incentive?
You may qualify if your project is completed by December 31, 2026, and Avista receives your complete application and required documents by January 15, 2027.
Does this affect my natural gas service?
No. This change only applies to Idaho natural gas energy efficiency rebates and incentives. Avista will continue to provide natural gas service.
Will these programs come back in the future?
Avista may offer natural gas energy-efficiency programs again if they meet Idaho’s cost-effective requirements in the future.
Why does this apply only in Idaho?
Avista serves customers in Washington, Idaho, and Oregon. Each state has different rules for utility programs. In Idaho, natural gas energy efficiency programs do not meet Idaho’s requirements for cost-effectiveness at this time.
