For many decades, Maine has stood apart from much of the United States in how its residents heat their homes. The state has a chilly climate, along with a unique energy distribution infrastructure. Moreover, its long-standing reliance on imported petroleum products has kept heating oil in Maine at the heart of residential HVAC choices.
While some regions shifted toward natural gas or electrical heating, Mainers continued to rely on oil for fuel. Mainers continued to lean on fuel oil. It bears important implications for cost, energy independence, and regional identity.
Today, that dynamic is shifting slowly as new technology and energy policies reshape how families warm their homes. Understanding the past helps make sense of present decisions and future trends.
Maine's dependence on residential heating oil has its roots in infrastructure, geography, and the past. Until recently, Maine was one of the states that relied on heating oil for most of its energy in the country.
Roughly half of Maine households still rely on heating oil as their primary heating source, down from nearly 70 percent in 2010. This trend reflects both historical practices and changing adoption patterns for alternative energy sources like heat pumps. (The Portland Press Herald)
Infrastructure Limitations
Unlike many parts of the U.S. that are served by extensive natural gas utility infrastructure, much of Maine, especially the rural areas, lacks a comprehensive pipeline network of gas. This makes centralized gas heating less accessible and more costly to implement than in states with developed grid distribution.
Instead, home heating oil is delivered by truck and stored in above-ground residential heating oil tanks, usually 275-gallon capacity or larger. These tanks are regulated by state authorities to prevent leaks and environmental harm. (Maine.gov)
In the late 20th century, when oil was abundant and heating technology advanced, Maine, along with other New England states, invested large amounts in oil-fueled boilers as well as furnaces. Oil was affordable and efficient compared to the previous system of wood and coal. To add up on this, the utility infrastructure simply didn’t evolve in Maine the way it did around natural gas hubs in the Midwest and South.
Over time, this long-established infrastructure reinforced oil heating as the default choice for many homes. With time, installers became familiar with oil systems, homeowners became accustomed to them, and local companies built their businesses around service, fuel delivery, and tank installation.
Despite this, the reliance on heating oil in Maine has decreased significantly over the last 10 years due to the use of electric heating pumps as well as energy efficiency programs. Between 2018 and 2024, the share of Maine homes using heating oil as their primary heat source declined from about 62 percent to just over 50 percent.
This decline, the most visible reduction in decades, is attributed to state and federal incentives for heat pumps, broader awareness of energy efficiency, and the rising cost volatility of petroleum products.
Heat pumps, which can both heat and cool, offer efficiency advantages over traditional oil furnace systems.
Since heating oil is delivered and not distributed through a pipeline, pricing can vary significantly by region, supply chain conditions, and seasonal demand.
According to the Maine Department of Energy Resources, the statewide average price for delivered heating oil is approximately $3.30–$3.37 per gallon. The highs can exceed $4.10 per gallon in some regions.
These figures reflect statewide averages. The heating oil prices in Portland, Southern Maine, Augusta, Long Island, and other areas can be higher or lower depending on the supplier, delivery fees, and seasonal demand.
Do You Know?
Heating oil prices tend to rise sharply in late fall and winter as demand increases. Unlike utilities tied to grid infrastructure, oil prices respond directly to global crude markets, shipping costs, and refinery output cycles.
Home heating oil is a refined petroleum product similar to diesel but formulated for residential furnaces and boilers. It’s stored on-site in tanks and burned to heat air or water, depending on the system.
In Maine homes, heating oil is almost always stored in above-ground residential heating oil tanks, typically in basements or outside. These tanks require routine inspection, cleaning, and sometimes replacement to avoid leaks, corrosion, or safety hazards.
One of the most common questions that homeowners ask is whether oil is cheaper than electric heating.
In the long term, heat pump systems may reduce total heating costs, especially when combined with efficiency upgrades. The upfront installation of Maine heating oil costs can be higher than simply maintaining existing oil systems.
Heating oil is a major contributor to greenhouse gas emissions, whereas electric heat pumps that are powered by low-carbon or renewable electricity can drastically reduce the carbon footprint of your home. The state policies and regulations in Maine actively encourage this change, not just to cut the cost of energy but also to achieve climate targets.
State policy in Maine actively promotes this transition, not only to lower energy costs but also to meet climate goals. Reductions in oil reliance contribute to cleaner air and less vulnerability to fossil fuel price swings.

Maine's past with heating oil is a remarkable connection between geography, infrastructure, and culture. Although it is still a significant component of residential heating oil for homes, the heating system that uses oil is now being replaced by newer, more efficient alternatives. The homeowner must weigh tradition with costs, environmental impact, and the future of energy trends.

As of late 2025, the statewide average price for delivered residential heating oil in Maine ranges between $3.30 and $3.37 per gallon, with prices varying by region and supplier.
Heating oil costs depend on location, delivery timing, and supplier. On average, cash prices across Maine hover around $3.30 per gallon, with regional lows near $2.75 and highs exceeding $4.10 per gallon.
Maine imports most of its heating oil from outside the state, primarily from Canadian refineries and the broader East Coast fuel supply chain, due to limited local refining and pipeline infrastructure.
Most Maine homes use No. 2 home heating oil for residential furnaces and boilers. It is specifically refined for efficient, reliable cold-weather performance.
Heat pumps and electric systems can be cost-effective long-term due to efficiency and stable electric rates. However, heating oil remains a strong option in very cold climates or areas with high electricity costs, especially during extreme winter temperatures.
