PORTLAND, Maine — Gas prices in northern New England have held about the same over the last week.

Prices are up in the region and all over the country compared to last year, but stayed the same in Maine and New Hampshire last week. GasBuddy’s daily survey said Monday that the average price in Maine was $3.10 per gallon. The price in New Hampshire was $2.98 per gallon.

Prices nosed up slightly in Vermont, where they increased 2.1 cents per gallon to $3.04 per gallon.

Maine’s average price was nearly 92 cents compared to a year ago. Patrick De Haan, head of petroleum analysis for GasBuddy, said the national average “hasn’t seen much meaningful direction as oil prices remain under their early-July levels thus far thanks to OPEC coming to an agreement on production over the weekend.”
