Connecticut peak weeks

Across the five seasons in the table, Connecticut's highest weekly reading was $5.97/gal in the 2022-23 season. The latest EIA reading, $5.99/gal for the week of 2026-11-02, is above every weekly reading in those five seasons. Nationally, adjusted for inflation, the highest calendar-year average since 2001 was 2012 at $5.87/gal in August 2026 dollars (see the 25-year history).

vs the Northeast 8

Across the seasons in the table, Connecticut's season average sits within $0.11/gal of the eight-state mean at its widest. That is the gap against the mean of the states on this site, computed from the table above, not against PADD1A: PADD1A is New England only, so New York and Pennsylvania are not in it. 31% of CT homes heat with oil, the highest oil-heat penetration in the lower NE. CT DEEP publishes a separate weekly survey.
