Heating Oil Price History in Rhode Island & Massachusetts

The retail market for home heating oil across New England is historically characterized by a distinct seasonal price cycle. This predictable pattern is dictated by a high concentration of residential space-heating consumption during the cold winter months, traditionally spanning October through March, which causes regional demand curves to shift dramatically.

To monitor these shifts, the US Energy Information Administration (EIA) compiles a residential heating oil price series as part of its State Heating Oil and Propane Program. This EIA weekly price series tracks markets continuously from October through March, shifting to a monthly collection on the second Monday of each month during the April-through-September shoulder and off-season.

Historically, residential heating oil prices fall to their lowest point-in-time levels during the late spring and summer months (June through August) when heating demand disappears. Prices then escalate into autumn and peak during the mid-to-late winter months of January, February, and March as freezing temperatures draw down regional stocks.

A look at historical baseline years illustrates this demand-driven escalation. During the 2017–2018 winter heating season, the price per gallon climbed from the October start to the late-winter March peak in this standard seasonal pattern, as documented in the EIA New England Dashboard:

Over the last several winter seasons, retail heating oil prices in Massachusetts and Rhode Island have departed significantly from historical averages due to extreme volatility — a multi-year trend heavily impacted by global supply shocks, beginning with post-pandemic reopenings and the 2022 Russia-Ukraine war.

The EIA Massachusetts Weekly Heating Oil Prices series and the EIA Rhode Island Weekly Heating Oil Prices series capture the major intervals across these seasons:

Retail prices paid by New England homeowners are the final output of a complex supply chain shaped by global oil benchmarks, refining economics, local weather, and physical infrastructure.

Global crude benchmarks. Crude oil is the single largest cost component of residential heating oil. According to the EIA Heating Oil Prices and Outlook breakdown, from the winter of 2012–2013 through 2021–2022, crude acquisition cost averaged 48% of the retail price of a gallon of heating oil, with distribution and marketing (37%) and refinery processing (15%) making up the rest. Because of this, retail rates are highly sensitive to global crude-benchmark prices, and markets embed a risk premium the moment a geopolitical crisis threatens oil-producing regions or maritime chokepoints, well before any physical disruption.

Refining economics. Heating oil is chemically No. 2 distillate — virtually identical to on-highway diesel and jet fuel, all refined from the same crude fraction and competing for regional refining capacity. As the EIA analysis of factors affecting heating oil prices explains, when supply configurations tighten, refiners shift yields to satisfy broader distillate demand, keeping wholesale replacement costs elevated and pushing retail prices up.

Weather (heating degree days). Localized weather dictates the velocity of demand, quantified as heating degree days (HDD) — the amount the mean daily temperature falls below 65°F. In southern New England, sudden storms or cold snaps trigger thousands of simultaneous automatic and will-call delivery requests, which can temporarily overwhelm local trucking and terminal racks and create localized price spikes even when global crude is stable.

Regional inventory. The US Northeast depends heavily on distillate for space heating but has almost no local refining. No refined-product pipeline from the Gulf Coast reaches New England — the major pipelines terminate at New York Harbor — so New England (PADD 1A) supply arrives almost entirely by tanker and barge to coastal terminals, from New York Harbor, Canadian, and overseas refineries. New England is therefore vulnerable to inventory depletions — when winter weather slows or blocks marine transit, terminal stocks draw down fast.

The common advice — buy in the summer off-season for the lowest annual price — is historically valid under normal conditions. In the low-demand months (April–September), wholesale margins compress and dealers compete for a smaller pool of orders, lowering point-in-time prices; filling a tank in summer also keeps interior walls free of condensation, reducing corrosion risk.

But it isn't foolproof. The clearest example is 2008: crude oil peaked near $145 per barrel in July 2008, and Northeast residential heating oil peaked in the high-$4/gal range that same summer — so a homeowner who topped off their tank then locked in the year's high. As the financial crisis collapsed demand through late 2008, residential heating oil fell by roughly half, to around $2.30/gal by early 2009, rewarding those who had waited (see the EIA residential heating oil price history and EIA crude oil spot prices). Two of the sharpest moves in the whole record, 2008 and 2022, came from outside the heating market entirely. (What that means for when to actually buy is the subject of its own guide.)

One more thing the history makes obvious: at any single moment, the price spread among competing dealers in the same delivery zone is frequently larger than the entire seasonal swing. Service model is the usual explanation for a gap that size — the full-service vs COD guide breaks it down — and what to do about it is covered in the best time to buy guide. This page is about what prices have done; those two are about what to do next.
