Why this number

In Rhode Island, the cheapest heat last winter was natural gas at about $22.53 per million Btu delivered, then heating oil at $34.95 and a cold-climate heat pump at $41.11; electric resistance was the most expensive at $89.21 (EIA average prices, October 2025–March 2026, converted with the site’s standard efficiencies). For this winter EIA’s September outlook moves national heating oil +35%, natural gas -10%, propane -5% and electricity +3%; applied to Rhode Island’s own prices, natural gas stays cheapest at about $20.33. The calculator below ranks every option from the prices on your bills.

Rhode Island paid 30.44¢/kWh for electricity last winter — 34 of 35 on this list of 35 cold-weather states — and $2.14 per therm for gas (34 of 35); propane ran $3.63/gal (33 of 35) and heating oil $4.11/gal (31 of 35). Put on one basis, dollars per million Btu delivered, natural gas was the cheapest heat at $22.53 and electric resistance the dearest at $89.21 — a 67-dollar gap per MMBtu, or about $4,001 over a 60-MMBtu season.

Price basis: Rhode Island’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.

Electric resistance (COP 1.00) $89.21 $5,353 $91.52 (+3%)

The season column is an illustrative 60 MMBtu of delivered heat; in Rhode Island that puts natural gas at $1,352 and electric resistance at $5,353 for the winter. The this-winter column applies EIA’s national STEO change per fuel to Rhode Island’s own price (oil +35% is the large one) — direction, not a state forecast.

The prices behind the table

Rhode Island fuel and electricity prices behind the comparison, with source, basis and vintage
Price Last winter average (Oct 2025–Mar 2026) Latest published reading Source and basis
Electricity 30.44¢/kWh 28.29¢/kWh (July 2026) EIA Electric Power Monthly 5.6.A; winter average from the monthly editions
Natural gas $2.14/therm ($22.24/Mcf, 5 of 6 months reported) $25.75/Mcf (June 2026, shoulder-season price) EIA Natural Gas Monthly, residential price by state; 1 Mcf = 10.38 therms
Heating oil $4.11/gal $5.80/gal (week of 2026-03-30) EIA SHOPP weekly survey, Rhode Island, Oct 2025–Mar 2026 average
Propane $3.63/gal $3.76/gal (week of 2026-03-30) EIA SHOPP weekly survey, Rhode Island, Oct 2025–Mar 2026 average

Rhode Island’s winter gas average ($22.24/Mcf) sits close to its June figure ($25.75), so the seasonal fixed-charge effect that distorts most states’ summer prices is small here.

What Rhode Island’s utilities charge

Rhode Island's largest electric utilities and what resistance and heat-pump heat cost at each one's average price
Utility (largest by customers) Residential customers ¢/kWh (EIA-861 2024) Resistance $/MMBtu Heat pump at 17°F $/MMBtu
The Narragansett Electric Co 451,381 25.1¢ $73.56 $33.90
NextEra Energy Services, LLC 85,764 11.6¢ $34.00 $15.67
SmartEnergy Holdings, LLC 8,190 16.2¢ $47.48 $21.88

The statewide 30.44¢ hides a 13.5¢ spread between Rhode Island’s largest utilities, worth $39.56 per MMBtu on resistance heat and $18.23 on a heat pump. The ZIP lookup finds yours.

How Rhode Island homes are heated

Share of occupied housing units by main house-heating fuel in Rhode Island and the US, ACS 2019–2023 5-year (table B25040), 436,902 Rhode Island units
Main heating fuel Rhode Island homes US homes
Natural gas (utility) 53.4% 46.8%
Electricity 12.1% 40.8%
Propane (bottled, tank or LP gas) 4.9% 4.9%
Heating oil or kerosene 27.2% 4.1%
Wood 1.2% 1.4%

Natural gas heats 53.4% of Rhode Island’s 436,902 occupied homes against 46.8% nationally, with electricity at 12.1%, propane at 4.9% and heating oil at 27.2%. That lines up with the table above: natural gas was also Rhode Island’s cheapest heat last winter at $22.53 per MMBtu.

What the numbers say about Rhode Island

At last winter’s average prices, the cheapest way to heat a home in Rhode Island was natural gas at about $23 per million Btu delivered, and the most expensive was electric resistance at $89 — a 4.0× spread between the two columns. Gas beat a cold-climate heat pump at 17°F (COP 2.17) by $18.58/MMBtu, and at 47°F (COP 3.2, $27.88) the heat pump still trails. At Rhode Island’s winter rates the economic balance point lands above 47°F (COP 3.96 needed against 3.20 available), so the furnace is cheaper at every rated temperature. Heating oil averaged $4.11/gal across 26 SHOPP survey weeks and finished the season at $5.80 on March 30, 2026; EIA’s September outlook puts national oil +35% for this winter, which would carry Rhode Island’s figure to roughly $47/MMBtu. Propane averaged $3.63/gal in the state survey, with a national -5% outlook for this winter.

Heating degree-days: Rhode Island’s own figure and the EIA division forecast

Rhode Island itself logged 5,254 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 New England census division degree-days, the only one with a forecast for the coming winter; it groups Rhode Island with its neighbours and is not a Rhode Island figure:

EIA STEO New England census division heating degree-days (not a state figure): last winter actual and this winter forecast, month by month
Last winter (actual) HDD This winter (STEO forecast) HDD

Mar 2026 841 Mar 2027 852
Oct–Mar total 5,608 Oct–Mar total 4,975

January in the EIA New England census division (the coarse series that groups Rhode Island with its neighbours) averaged about 23°F last winter (65°F minus degree-days per day) and is forecast at 29°F for January 2027, a season move of -633 degree-days. Degree-days set how much heat Rhode Island needs, the table above sets the price per unit, and the bill jump calculator multiplies the two.

Heating oil prices in Rhode Island

EIA’s weekly SHOPP survey priced residential No. 2 heating oil in Rhode Island at $3.64/gal in the first October week of the 2025-26 season and $5.80 in the final March week — a season average of $4.11, low $3.61, high $5.81, against a national average of $4.01. The survey resumes in October 2026; the weekly tracker carries every state.

Where the heat pump crosses over in Rhode Island

At last winter’s averages of 30.44¢/kWh and $2.14/therm, a heat pump beats a 95% gas furnace whenever its COP exceeds 3.96. Rhode Island’s economic balance point on the NEEP median curve is above 47°F (COP 3.96 needed against 3.20 available), so the furnace is cheaper at every rated temperature; the crossover tool runs seven named units at Rhode Island’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 Rhode Island fresh state propane and heating-oil readings on the weekly tracker .

Frequently asked questions

What is the cheapest way to heat a home in Rhode Island?

On last winter’s EIA average prices, natural gas at about $22.53 per million Btu delivered, against heating oil at $34.95 and a cold-climate heat pump at $41.11. Rhode Island’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 Rhode Island’s fixed monthly charges and equipment prices sit outside it.

Is a heat pump cheaper than gas in Rhode Island?

At Rhode Island’s last-winter averages of 30.44¢/kWh and $2.14/therm, a heat pump needs a COP above 3.96 to beat a 95% furnace. Against Rhode Island’s required COP 3.96, the NEEP medians (3.20/2.17/1.90 at 47/17/5°F) mean the heat pump loses at every rating point in Rhode Island; the balance point is above 47°F (COP 3.96 needed against 3.20 available), so the furnace is cheaper at every rated temperature.

How much will heating oil and propane cost in Rhode Island this winter?

Nobody publishes a Rhode Island forecast; applying EIA’s September STEO national changes (+35% oil, -5% propane) to Rhode Island’s last-winter $4.11 and $3.63 per gallon gives roughly $5.53 and $3.46 — the ’this winter’ column. Rhode Island’s weekly SHOPP readings resume in October; the Winter Fuels Outlook (October 6) adds household expenditure on top.

Where do the Rhode Island prices on this page come from?

30.44¢/kWh is the EIA Electric Power Monthly average for Rhode Island over the October 2025–March 2026 editions (28.29¢ in July 2026); the share of homes on each heating fuel is Census ACS 2019–2023 5-year table B25040; $22.24/Mcf is the Natural Gas Monthly winter average (5 months), converted at 10.38 therms per Mcf; oil $4.11 and propane $3.63 per gallon are SHOPP state season averages; degree-days are the STEO New England series. Only the ’this winter’ column is an estimate.

How we calculated this

Worked for Rhode Island at last winter’s averages: gas 10 × $2.14 ÷ 0.95 = $22.53/MMBtu; propane 10 × ($3.63 ÷ 0.91452) ÷ 0.92 = $43.13; oil 10 × ($4.11 ÷ 1.385) ÷ 0.85 = $34.95; resistance 293.07 × 0.3044 = $89.21; heat pump $89.21 ÷ 2.17 = $41.11. 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).
