Rural Alaskans across remote villages and hub communities are confronting fuel prices that could double this year and potential supply shortages that threaten heating, electricity and transportation, according to fuel distributors and local officials.

Gas and heating fuel already cost $17.50 per gallon in Ambler, a Northwest Alaska village. Unleaded gas in Bethel, a Western Alaska hub, reached $6.72 per gallon. Rural utilities paid $3.10 per gallon for diesel last year. That price could top $6 per gallon this year, distributors say.

A war in Iran has disrupted fuel supplies and driven prices higher. Fuel distributor Custard warned in a March 31 letter of a credible supply gap for rural Alaska deliveries and described the potential outcome as a "survival scenario" if shortages materialize during the coming winter heating season.

Ingemar Mathiasson, energy manager for the Northwest Arctic Borough, is among local officials and vendors reporting credible shortages. Residents have provided accounts of struggling to afford heating, food and essentials.

Alaska Center for Energy and Power economist Steve Colt's data shows rural Alaskans use about 1,200 gallons of fuel per person each year for heating, transportation and electricity. A 50% price increase would add roughly $6,000 per person in annual fuel costs. That totals $450 million statewide in additional expenses.

The fuel supply disruption compounds existing challenges in communities where prices already strained household budgets.

Sen. Lisa Murkowski has raised concerns that decreasing national fuel prices could create additional difficulties for rural Alaska by reducing state oil revenue that funds subsidy programs helping offset high fuel costs in remote areas.

Fuel prices in rural Alaska have long exceeded urban rates because of transportation costs and limited infrastructure. Villages accessible only by air or barge face the highest prices.

Rural communities typically receive fuel deliveries during brief summer barge windows. Missing those deliveries or facing severe shortages could leave villages without adequate fuel for heating and power generation.

Local officials continue monitoring fuel supplies and prices as the summer barge season approaches. Communities face decisions about fuel purchases and rationing strategies if prices remain high or supplies fall short of needs.
