Why this number
Oregon paid 15.15¢/kWh for electricity last winter — 14 of 35 on this list of 35 cold-weather states — and $1.60 per therm for gas (23 of 35); propane ran $2.56/gal (17 of 35) and heating oil $3.94/gal (19 of 35). Put on one basis, dollars per million Btu delivered, natural gas was the cheapest heat at $16.84 and electric resistance the dearest at $44.40 — a 28-dollar gap per MMBtu, or about $1,653 over a 60-MMBtu season.
Price basis: Oregon’s fuel prices are last winter’s measured EIA and SHOPP averages; the this-winter column scales each by EIA’s national STEO change for that fuel — a labelled estimate, not a state forecast.
Oregon heating cost per MMBtu, fuel by fuel
| Heating option | $/MMBtu delivered, last winter | Season cost at 60 MMBtu | This winter, EIA outlook applied |
|---|---|---|---|
| Natural gas furnace (95% AFUE) | $16.84 | $1,011 | $15.20 (-10%) |
| Propane furnace (92% AFUE) | $30.43 | $1,826 | $29.00 (-5%) |
| Heating oil boiler (85% AFUE) | $33.47 | $2,008 | $45.02 (+35%) |
| Heat pump at 47°F (COP 3.20) | $13.88 | $833 | $14.23 (+3%) |
| Heat pump at 17°F (COP 2.17, NEEP median 3-ton ducted) | $20.46 | $1,228 | $20.99 (+3%) |
| Heat pump at 5°F (COP 1.90) | $23.37 | $1,402 | $23.97 (+3%) |
| Electric resistance (COP 1.00) | $44.40 | $2,664 | $45.55 (+3%) |
The season column is an illustrative 60 MMBtu of delivered heat; in Oregon that puts natural gas at $1,011 and electric resistance at $2,664 for the winter. The this-winter column applies EIA’s national STEO change per fuel to Oregon’s own price (electricity +3%) — direction, not a state forecast.
The prices behind the table
| Price | Last winter average (Oct 2025–Mar 2026) | Latest published reading | Source and basis |
|---|---|---|---|
| Electricity | 15.15¢/kWh | 15.97¢/kWh (July 2026) | EIA Electric Power Monthly 5.6.A; winter average from the monthly editions |
| Natural gas | $1.60/therm ($16.61/Mcf, 6 of 6 months reported) | $21.60/Mcf (June 2026, shoulder-season price) | EIA Natural Gas Monthly, residential price by state; 1 Mcf = 10.38 therms |
| Heating oil | $3.94/gal | $5.30/gal (STEO forecast, national) | EIA STEO national average Oct 2025–Mar 2026 — no SHOPP state or regional heating oil series |
| Propane | $2.56/gal | $2.44/gal (STEO forecast, national) | EIA STEO national average Oct 2025–Mar 2026 — no SHOPP state or regional propane series |
Oregon’s June gas figure ($21.60/Mcf) runs 1.3× its winter average ($16.61) because EIA’s residential price is average revenue per Mcf with the fixed charge folded in; the high-volume winter months are the closest published proxy for the marginal rate this page needs.
What Oregon’s utilities charge
| Utility (largest by customers) | Residential customers | ¢/kWh (EIA-861 2024) | Resistance $/MMBtu | Heat pump at 17°F $/MMBtu |
|---|---|---|---|---|
| Portland General Electric Co | 828,857 | 18.2¢ | $53.34 | $24.58 |
| PacifiCorp | 547,235 | 14.0¢ | $41.03 | $18.91 |
| City of Eugene - (OR) | 89,582 | 13.1¢ | $38.39 | $17.69 |
The statewide 15.15¢ hides a 5.1¢ spread between Oregon’s largest utilities, worth $14.95 per MMBtu on resistance heat and $6.89 on a heat pump. The ZIP lookup finds yours.
How Oregon homes are heated
| Main heating fuel | Oregon homes | US homes |
|---|---|---|
| Natural gas (utility) | 37.1% | 46.8% |
| Electricity | 53.1% | 40.8% |
| Propane (bottled, tank or LP gas) | 2.0% | 4.9% |
| Heating oil or kerosene | 1.3% | 4.1% |
| Wood | 5.1% | 1.4% |
Electricity heats 53.1% of Oregon’s 1,701,548 occupied homes against 40.8% nationally, with electricity at 53.1%, propane at 2.0% and heating oil at 1.3%. The table above says otherwise for last winter: the households on electricity paid about $44.40 per MMBtu while natural gas delivered the same heat for $16.84, a $27.56 gap on every million Btu.
What the numbers say about Oregon
At last winter’s average prices, the cheapest way to heat a home in Oregon was natural gas at about $17 per million Btu delivered, and the most expensive was electric resistance at $44 — a 2.6× spread between the two columns. Gas beat a cold-climate heat pump at 17°F (COP 2.17) by $3.62/MMBtu, and at 47°F (COP 3.2, $13.88) the heat pump pulls ahead. At Oregon’s winter rates the economic balance point lands about 31°F (COP 2.64 needed). No EIA state or regional heating-oil series exists for Oregon; the oil row is the national STEO average ($3.94/gal last winter, $5.30 forecast) and is labelled as such. Propane, likewise, is the national STEO figure of $2.56/gal because SHOPP does not cover Oregon.
Heating degree-days: Oregon’s own figure and the EIA division forecast
Oregon itself logged 3,685 population-weighted heating degree-days from October 2025 to March 2026 (NOAA Climate Prediction Center state series, base 65°F), against 3,500 for the contiguous US. The month-by-month table below is a different, coarser series — EIA STEO Pacific census division degree-days, the only one with a forecast for the coming winter; it groups Oregon with its neighbours and is not a Oregon figure:
| Last winter (actual) | HDD | This winter (STEO forecast) | HDD |
|---|---|---|---|
| Oct 2025 | 216 | Oct 2026 | 194 |
| Nov 2025 | 340 | Nov 2026 | 391 |
| Dec 2025 | 445 | Dec 2026 | 562 |
| Jan 2026 | 487 | Jan 2027 | 540 |
| Feb 2026 | 403 | Feb 2027 | 459 |
| Mar 2026 | 260 | Mar 2027 | 424 |
| Oct–Mar total | 2,151 | Oct–Mar total | 2,570 |
January in the EIA Pacific census division (the coarse series that groups Oregon with its neighbours) averaged about 49°F last winter (65°F minus degree-days per day) and is forecast at 48°F for January 2027, a season move of +419 degree-days. Degree-days set how much heat Oregon needs, the table above sets the price per unit, and the bill jump calculator multiplies the two.
Where the heat pump crosses over in Oregon
At last winter’s averages of 15.15¢/kWh and $1.60/therm, a heat pump beats a 95% gas furnace whenever its COP exceeds 2.64. Oregon’s economic balance point on the NEEP median curve is about 31°F (COP 2.64 needed); the crossover tool runs seven named units at Oregon’s prices and the dual-fuel calculator turns the answer into a changeover setting.
From October 6 the EIA Winter Fuels Outlook adds household expenditure by region and the weekly SHOPP survey restarts, giving Oregon fresh regional propane readings on the weekly tracker .
Frequently asked questions
What is the cheapest way to heat a home in Oregon?
On last winter’s EIA average prices, natural gas at about $16.84 per million Btu delivered, against a cold-climate heat pump at $20.46 and propane at $30.43. Oregon’s ranking uses a 95% gas furnace, 92% propane furnace, 85% oil boiler and a heat pump at COP 2.17; it is per unit of heat, so Oregon’s fixed monthly charges and equipment prices sit outside it.
Is a heat pump cheaper than gas in Oregon?
At Oregon’s last-winter averages of 15.15¢/kWh and $1.60/therm, a heat pump needs a COP above 2.64 to beat a 95% furnace. Against Oregon’s required COP 2.64, the NEEP medians (3.20/2.17/1.90 at 47/17/5°F) mean the heat pump wins on mild days and loses in a cold snap in Oregon; the balance point is about 31°F (COP 2.64 needed).
How much will heating oil and propane cost in Oregon this winter?
Nobody publishes a Oregon forecast; applying EIA’s September STEO national changes (+35% oil, -5% propane) to Oregon’s last-winter $3.94 and $2.56 per gallon gives roughly $5.30 and $2.44 — the ’this winter’ column. Oregon’s weekly SHOPP readings resume in October; the Winter Fuels Outlook (October 6) adds household expenditure on top.
Where do the Oregon prices on this page come from?
15.15¢/kWh is the EIA Electric Power Monthly average for Oregon over the October 2025–March 2026 editions (15.97¢ in July 2026); the share of homes on each heating fuel is Census ACS 2019–2023 5-year table B25040; $16.61/Mcf is the Natural Gas Monthly winter average (6 months), converted at 10.38 therms per Mcf; oil $3.94 and propane $2.56 per gallon are SHOPP season averages, regional or national where marked; degree-days are the STEO Pacific series. Only the ’this winter’ column is an estimate.
How we calculated this
Worked for Oregon at last winter’s averages: gas 10 × $1.60 ÷ 0.95 = $16.84/MMBtu; propane 10 × ($2.56 ÷ 0.91452) ÷ 0.92 = $30.43; oil 10 × ($3.94 ÷ 1.385) ÷ 0.85 = $33.47; resistance 293.07 × 0.1515 = $44.40; heat pump $44.40 ÷ 2.17 = $20.46. The this-winter column multiplies each by EIA’s national STEO change for that fuel (electricity ×1.026, gas ×0.903, propane ×0.953, oil ×1.345).Sources: U.S. Energy Information Administration (EIA) electricity rates · DSIRE incentive records · public IRS/OBBBA guidance.
