Your Local Electric Cooperative
Many Idaho electric cooperatives (such as Kootenai Electric, Fall River Electric, or Clearwater Power) offer rebates for upgrading old windows and exterior doors. These programs are typically funded through the Bonneville Power Administration (BPA) and are designed to help co-op members reduce electricity use. While each co-op sets its own exact rules, the rebates follow a similar structure.
- Rebate amount: Windows: about $5.00 per square foot of new qualifying window glass. For example, replacing a 15 sq. ft. single-pane window could earn roughly $75 back. Exterior doors: about $40 per insulated, ENERGY STAR® rated door. Some co-ops also set maximum rebate caps (e.g., $600 total for windows).
- Eligibility: Must be a residential member of the cooperative and your home must typically use electric heat as the primary heating source. Rebates apply to existing homes only (not new construction). Old windows must generally be single-pane or aluminum-frame double-pane, and replacement windows must meet ENERGY STAR standards (U-factor ≤ 0.30).
- Application process: Contact your local co-op before starting the project. Most require pre-approval or an energy audit to confirm your current windows/doors qualify. After installation, submit invoices, NFRC labels, and rebate forms. Rebates are usually paid as a check or a credit on your electric bill.
- Limitations: Rebates are first-come, first-served each funding cycle and expire if you do not complete the work within 3–6 months of approval. Rebates cannot exceed the project cost, and you cannot claim multiple BPA-funded incentives for the same window or door.
