Analysis

Colorado's record: refinery outages and wide swings

The clearest event in Colorado’s weekly record is the Suncor refinery shutdown. Cold-weather damage shut the plant around Christmas 2022, and it restarted in stages from February 9, 2023, returning to near-full operation by the end of March. Colorado’s average rose from $3.07 in the week of January 9, 2023 to $3.90 in the week of February 6, while the U.S. average moved from $3.26 to $3.44. In the week of February 20, Colorado was 72.5¢ above the national average, the widest gap in its series. By April 3 it was back below the U.S. average.

Otherwise Colorado has usually been cheaper than the country as a whole. Its yearly average was below the U.S. average in most years since 2003, by as much as 25¢ in 2024. The exceptions were 2020 and 2021, when it ran 4¢ and 12¢ above, and 2023, when it averaged under a cent (0.5¢) above. The widest gap below the national average was 62.1¢, in the week of December 8, 2025.

Colorado’s record weekly average is $4.87, in the week of June 20, 2022, a week after the U.S. record and still below the U.S. average that week. The 2008 peak was $4.03 in the week of July 14, and the 2020 low was $1.64 in the week of May 11. The lowest price in the series is $1.04, in December 2001.

The state’s weekly moves are large in both directions. In 2026, Colorado began the year at $2.19, rose 63¢ in the single week of March 9, the largest one-week increase in its record, and peaked at $4.62 in the week of May 18. The two largest one-week declines in its record followed within weeks: 34.4¢ in the week of June 1 and 28.4¢ in the week of June 22, 2026.
