Maine's own survey, alongside the EIA week above
Maine is one of the states whose energy office surveys delivered retail propane all year round and publishes the result, weekly in winter and every two weeks or so in summer, including through the months when EIA's national survey is silent. Maine Department of Energy Resources put the Maine statewide average at $3.46 per gallon on 5 October 2026, against the $3.546 EIA reading for the week ending 5 October 2026. The two are different surveys with different methods, so read the 9 cent gap as direction, not as a measured seasonal move.

What drives the Maine price
Maine sits in PADD 1A (New England) with residential prices well above the national average, reflecting the rail-and-truck supply chain that serves the whole region. Maine is also one of the few states with an independent published price series: the Maine Department of Energy Resources runs its own heating fuels survey alongside EIA's, weekly in the heating season and every other week from May to August, which makes Maine prices unusually easy to cross-check.
