Window and Insulation Rebates in the Portland Metro and Southwest Washington: Which Program Covers Your House

The rebate you can get for new windows or insulation depends on two things most homeowners never check: which utility bills you, and whether your house is heated with gas or electricity. This page maps every city VResh serves to the program that applies, with the current amounts read from each program's own page and linked so you can verify them.

What this means when you plan a project

For a gas heated home in Beaverton, Lake Oswego or anywhere else in the Oregon metro, the money in 2026 is in insulation, not windows: Energy Trust will pay per square foot for attic, wall and floor insulation installed by a trade ally, and the same crew doing siding or window work can usually add wall insulation while the siding is off. Windows still pay back in comfort, noise and resale, but there is no cash back to build the budget around.

Across the river the picture flips. A Vancouver, Camas or Battle Ground home with NW Natural gas heat can get $10 per square foot from Energy Trust on windows that replace single pane or metal framed double pane, which on a typical 1970s ranch is a meaningful share of the window bill. An electrically heated home in the same neighborhoods goes through Clark Public Utilities instead, at $6 to $10 per square foot depending on what is being replaced and how efficient the new window is, plus $40 per exterior door.

The coast and Columbia County are their own world: Central Lincoln PUD in Lincoln City pays $8 to $10 per square foot on windows for electrically heated homes, and Columbia River PUD in Scappoose runs a similar program with a home energy review before and an inspection after.

OUR FAQS

Questions about this data

Why is there no window rebate for most Oregon homes in 2026?
+
Energy Trust of Oregon, which runs incentives for PGE, Pacific Power, NW Natural and Cascade Natural Gas customers, currently offers window cash back only to Southwest Washington customers of NW Natural. The federal 25C tax credit that covered up to $600 for windows ended for anything installed after December 31, 2025. The exceptions in Oregon are the customer owned electric utilities on the coast and in Columbia County, Central Lincoln PUD and Columbia River PUD, plus Salem Electric, all of which run their own programs for electrically heated homes.
Why does the electric utility matter so much in Washington?
+
Clark Public Utilities, Cowlitz PUD and Pacific County PUD are customer owned utilities that fund their own weatherization rebates through the Bonneville Power Administration, and every one of them requires the home to be electrically heated. If your Clark County home is heated with NW Natural gas instead, you go through Energy Trust, which pays $10 per square foot for qualifying windows. The heat source, not the address, decides which program you use.
Do I have to use a specific contractor?
+
Usually yes. Energy Trust incentives are delivered through trade ally contractors. Clark Public Utilities requires a Contractor Network member. Cowlitz PUD requires pre authorization and a Washington licensed and bonded contractor. Central Lincoln allows owner installation but requires final invoices and NFRC stickers. VResh is enrolled where the programs apply to its work and handles the paperwork.
Is the federal tax credit really gone?
+
Yes. The Energy Efficient Home Improvement Credit under section 25C was ended by the One Big Beautiful Bill Act for property placed in service after December 31, 2025. Work completed in 2025 can still be claimed on the 2025 return. Work completed in 2026 or later does not qualify for a federal credit.
How current is this page?
+
Every amount was read from the program's own page on the date shown at the top, and each program links to its source. Utility programs change amounts without notice, sometimes mid year, so confirm the current figure with the program before signing a contract. Where a program publishes its amounts inside a form that could not be read, this page describes the program and links to it rather than printing a number.
