Energy Trust of Oregon Heat Pump Incentives: How Rebates Differ Between PGE and Pacific Power Territory

Have you heard of Energy Trust of Oregon? If you own a home in Portland, Bend, Medford, or Corvallis and you have priced a heat pump in the past year, the incentive line on your bid almost certainly traced back to it.

Energy Trust is an independent nonprofit, created in 2002, that administers efficiency and renewable energy incentives on behalf of Oregon's regulated utilities. That structure surprises homeowners who assume the money originates in Salem, in Washington, or at the utility whose logo sits on the bill.

The practical consequence is narrow and expensive. The same equipment, installed by the same contractor, on two houses a few blocks apart, can carry two different incentive outcomes — and what moves the answer is which meter serves the address.

What Energy Trust Of Oregon Actually Administers

Energy Trust is funded by a public purpose charge established under Oregon Senate Bill 1149 in 1999, collected on the retail electric revenue of the state's investor-owned utilities. It receives additional funding from the regulated natural gas utilities for gas efficiency measures.

On the electric side, that means exactly two utilities: Portland General Electric and Pacific Power. On the gas side, it means NW Natural, Cascade Natural Gas, and Avista.

Every residential heat pump incentive Energy Trust pays is therefore tied to a specific service address, rather than to a homeowner or a contractor. The verification step is the meter, and it happens before an incentive is approved — not after the equipment is on the pad.

The Territory Split, In Plain Geography

PGE serves approximately 900,000 customers concentrated in the northern Willamette Valley — most of Portland, Gresham, Beaverton, Hillsboro, Oregon City, Salem, and the Mount Hood corridor. Pacific Power serves approximately 600,000 Oregon customers spread far more widely, including Bend, Medford, Grants Pass, Klamath Falls, Roseburg, Coos Bay, Astoria, Albany, and Corvallis.

Both utilities also serve pieces of the Portland metro. Pacific Power's Oregon territory takes in a portion of downtown and northwest Portland, which is why a Pearl District condo and an inner-southeast bungalow can land in different territories while sharing a metro area and, in places, a ZIP code.

Because both are Energy Trust funders, crossing that particular boundary does not remove you from the program. Crossing into a consumer-owned utility does, and that is the boundary worth checking first.

Who Is Left Out Entirely

Oregon has an unusually large consumer-owned utility sector — municipal utilities, people's utility districts, and rural electric cooperatives — that does not collect the SB 1149 public purpose charge. Those customers sit outside Energy Trust's residential electric programs.

The list is long enough to catch people off guard. Eugene Water & Electric Board, Springfield Utility Board, Salem Electric, Emerald PUD, Central Lincoln PUD, Tillamook PUD, Clatskanie PUD, Columbia River PUD, Forest Grove Light & Power, McMinnville Water & Light, Canby Utility, the City of Ashland, and cooperatives including Central Electric, Lane Electric, Consumers Power, Douglas Electric, and Umatilla Electric all run their own offerings instead.

Two examples make the stakes concrete. A house in Bend on Pacific Power is inside Energy Trust territory, while a house a short drive north on Central Electric Cooperative is not.

Salem is the sharper case. Most of the city is PGE, and therefore Energy Trust territory, while West Salem and portions of the Keizer area are served by Salem Electric, a member-owned cooperative with an entirely separate incentive schedule.

Ductless Versus Ducted: Two Different Incentive Logics

Energy Trust's residential heat pump incentives are not a single number, and the split between ductless and ducted is where most of the confusion starts. The two paths are underwritten on different assumptions about where the savings come from.

Ductless (Mini-Split) Incentives

Ductless incentives are priced against the heating system you displace, because modeled savings are calculated from avoided kilowatt-hours. The largest tiers have historically been reserved for homes heated by electric resistance zonal equipment — baseboards, cadet-style wall heaters, ceiling cable, and electric wall furnaces.

A home already heated by a gas furnace generally sees a much smaller ductless incentive, or none at all, because the modeled electric savings simply are not there. That is a program-design outcome rather than a contractor error, and it is worth understanding before a bid lands in your inbox.

Ducted Heat Pump Incentives

Ducted incentives are keyed primarily to equipment performance and to the system being replaced. Tiers are defined against AHRI-listed ratings — generally HSPF2 and SEER2 — with higher-efficiency variable-speed inverter equipment landing in the upper brackets.

Duct sealing and insulation typically carry their own separate incentives, and in a leaky Willamette Valley crawlspace those measures often move operating cost more than a single equipment tier upgrade does. Our breakdown of duct static pressure and heat pump airflow covers why a high-tier coil on undersized ductwork rarely delivers its rated performance.

Published amounts in both categories move at least annually, and Energy Trust periodically restructures tiers mid-year as measure savings are re-evaluated. Rather than repeat a figure that will be stale by the time you read it, treat the current residential incentive sheet as the only authoritative source and record its revision date when you download it.

Where The Two Territories Genuinely Diverge

The measure list across PGE and Pacific Power territory is largely aligned, which is why the split often gets dismissed as cosmetic. The divergence shows up in four places instead.

First, funding is tracked separately. Each utility's public purpose charge funds its own territory's programs, and Energy Trust budgets, forecasts, and reports by utility — so a measure can be heavily subscribed on one side while still comfortably funded on the other.

Second, the gas overlay differs. NW Natural dominates the PGE footprint, while Cascade Natural Gas and Avista appear in parts of Pacific Power territory, and large stretches of Pacific Power's rural service area have no piped gas at all.

Third, income-qualified pathways route differently. Energy Trust's moderate-income offer layers on top of the standard incentive, but the community action agencies and delivery partners handling enrollment vary by county, and county coverage does not follow utility lines cleanly.

Fourth, the building stock and the climate diverge sharply, which changes which tier is actually worth buying. That last one deserves its own section.

The Climate Layer: Bend Is Not Portland

Oregon spans three IECC climate zones. Western valley and coastal counties sit in marine zone 4C, most of central and eastern Oregon falls into 5B, and the high desert around Burns and Baker City reaches 6B.

PGE's territory is almost entirely 4C. Pacific Power's territory, by contrast, carries most of the state's genuinely cold design conditions.

The consequence for equipment selection is direct. A 4C home near a 27°F design temperature can reach a comfortable balance point with mainstream variable-speed equipment, while a Bend or Klamath Falls home needs either cold-climate-rated capacity retention or a deliberate backup-heat strategy.

This is exactly where a rebate tier and a correct system can pull apart. Our guides to cold-climate heat pump sizing and cold-climate heat pump brands cover capacity at design temperature, and heat pump backup heat sizing covers what happens during the coldest one percent of hours.

Keep in mind that an incentive tier is a rebate rule, not a sizing recommendation. The load number still has to come from an ACCA Manual J run on your actual envelope, which you can begin with our heat pump load calculator.

One further territory-specific constraint: electric-resistance-heated homes across Pacific Power's rural footprint frequently sit on older service panels. Before committing to a ducted system with backup strips, our notes on heat pump panel capacity explain how a 100-amp service narrows the design options.

Where The State Layer Attaches

Oregon's state-level heat pump money runs through the Oregon Department of Energy, separately from Energy Trust and on separate eligibility rules. It attaches at application rather than at the invoice.

Three ODOE efforts matter most for residential heat pumps. The Community Heat Pump Deployment Program funds delivery through community organizations, the Rental Home Heat Pump Program funds installations in rental housing, and Oregon's Home Energy Rebates implement the federal IRA Sections 50121 and 50122 programs commonly called HOMES and HEEHRA.

Critically, the ODOE programs are not confined to investor-owned utility territory the way Energy Trust is. A homeowner served by EWEB or a rural cooperative — shut out of Energy Trust entirely — may still be eligible on the state track.

HEEHRA is state-administered nationwide, and rollout timing, income tiers, and contractor requirements vary considerably from state to state. Our HEEHRA state guide tracks how those pieces differ, and HEEHRA and 25C stacking covers the interaction rules between the two.

Remember that ratepayer-funded and federally-funded incentives cannot always both pay toward the same measure. Verify order of operations with both administrators before an installation date is locked, because retroactive corrections are rare.

Where The Federal Layer Attaches

The federal layer attaches last, at your tax return, and it has moved. Federal residential incentives were restructured at the end of 2025, and the residential solar credit expired on December 31, 2025 — state and utility programs continue, but the federal picture should not be assumed from a 2024-era article.

Before planning around a federal number, confirm the current position on our federal tax credit status page and the timing rules covered in the annual 25C reset. If you are choosing between tracks, the 25C versus HEEHRA decision tree lays out which path fits which income and tax profile.

Note that a tax credit is worth only what your liability can absorb, whereas a utility incentive and a state rebate reduce the invoice directly. For a household with little federal tax liability, that ordering matters far more than the headline percentage does.

A Verification Sequence For Your Own Address

The sequence below is decision-support rather than an application checklist, and each step produces a document you will want later. Work it in order.

• Confirm the electric utility of record. Read the utility name from a current bill for the service address, not the mailing address, and note the account's rate schedule while you are there.
• Confirm Energy Trust eligibility. If the utility is PGE or Pacific Power you are in territory; if it is a PUD, a municipal utility, or a cooperative, go directly to that utility's own program and to ODOE.
• Identify the existing heating system precisely. Zonal electric resistance, electric forced air, gas furnace, propane, and oil all lead to different incentive tiers, and a photograph of the nameplate settles arguments later.
• Pull the current incentive sheet and record its revision date. Amounts and tier definitions change, and the date on that sheet is your evidence of what was published when you signed.
• Confirm trade ally status in writing. Most Energy Trust residential incentives require an installer in the Trade Ally Network, and the contractor generally submits the paperwork on your behalf.
• Get a Manual J before you get a tier recommendation. A load calculation on your envelope, at your design temperature, is what tells you whether the higher tier buys capacity you will actually use.

All six steps produce the same underlying output: a paper trail tying one address to one utility, one existing system, and one published incentive schedule. That is precisely what an incentive reviewer is checking.

PGE Versus Pacific Power At A Glance

The table below summarizes the structural differences homeowners run into most often. Figures are approximate and directional — verify them against current utility and Energy Trust publications before you build a budget around them.

Overall, the pattern holds steady: the two territories share an administrator and diverge on climate, fuel availability, building stock, and budget cycle. That is more than enough divergence to change which incentive tier is worth pursuing, even where the published amount looks identical.

Frequently Asked Questions

Working Out Your Own Answer

An Oregon heat pump decision stacks four layers onto one address: the utility that serves the meter, the Energy Trust measure tied to the system you are removing, the ODOE program that may apply regardless of utility, and whatever the federal code currently allows. They attach at different moments, and they are verified by different people.
