The Governor’s Energy Office (GEO) conducts a survey of heating fuel prices obtained from delivered fuel retailers statewide. This survey provides the current Maine cash prices, in dollars, rounded to the nearest penny. Prices are updated each week during the heating season (September through April) and every other week during the off season (May through August).
Maine Retail Heating Fuel Prices as of July 21, 2025
| Fuel Type | Statewide | Southwest / West-Central |
Southeast / Greater Portland |
Central | East / Downeast | Northern |
|---|---|---|---|---|---|---|
| Heating Oil - Average | $3.40 | $3.42 | $3.52 | $3.32 | $3.41 | $3.34 |
| Heating Oil - High | $4.60 | $4.60 | $4.60 | $4.60 | $4.60 | $3.45 |
| Heating Oil - Low | $2.95 | $2.95 | $3.04 | $2.95 | $2.99 | $3.10 |

Propane |
$3.02 | $3.21 | $3.45 | $2.84 | $2.88 | $2.83 |
*Please Note: The price for the various delivered heating fuels are statewide averages, and prices in a given geographic region of the state may be considerably higher or lower than this average. These statewide averages are spot cash prices, and not ‘pre-buy’, introductory, or otherwise discounted prices. Average propane prices are 30-day cash/credit prices, based on consumption of at least 900 gallons a year. Households using propane just for cooking or hot water generally pay a higher per gallon price.
The Governor’s Energy Office has developed a guide to assist consumers in obtaining the best propane price for their household and location. The guide can be accessed here - Propane Pricing: A Guide for Maine Consumers (PDF).
Average Heating Cost by Fuel Type and System
Below is a dashboard that compares the statewide average cost in dollars per million Btu (MMBtu) of various heating fuels when taking into account heating system efficiencies. Heating costs are estimated in dollars per MMBtu for a comparison between different heating systems using different fuel sources. The dashboard is updated to reflect current Maine energy prices included in the table above. Prices below are based on statewide averages and may vary depending on building efficiency (i.e., weatherization), weather, and other factors such as the heating fuel provider in your local area. The dashboard is intended to help consumers compare the average cost of heating based on various fuel inputs and heating systems and does not consider the cost of installing a new appliance.
Notes
- Firewood: Prices are based on an informal survey of dealers across the state and include (1) a minimum of 2 cord purchase of partially seasoned wood and (2) local delivery charges.
- Wood pellets: Prices are based on an informal survey of dealers across the state and include (1) average prices per ton, (2) Maine produced pellets in 40lb bags, and (3) local delivery charges. Bulk pellet prices may be slightly higher.
- Natural gas: Prices include minimum monthly fees and are dependent on location as natural gas and electricity delivery companies operate only in selected areas of the state. Natural gas prices in Maine vary across service areas.
- Electric heating: Electric system prices (heat pumps and electric baseboard) do not include monthly minimum electricity fees. Generally, residential consumers pay the same monthly minimum electricity fees regardless of whether they use fossil fuel heating systems, electric heating systems, or a combination of both. These monthly fees will also vary for those customers in consumer owned utilities.
- Heating system efficiencies: The system and distribution efficiency of each heating system is derived from Efficiency Maine. Efficiency Maine maintains a similar page which estimates annual costs.
- Water heating: For operating costs associated with various water heating appliances, visit Efficiency Maine’s water heating costs webpage.
