"There is no extra gas in this market."
That's John Sims, president of Enstar Natural Gas, describing the state of Cook Inlet's gas supply to state lawmakers this month. He wasn't talking about prices. He was talking about physical volume, the actual molecules that heat most Anchorage homes through the winter, and telling the legislature's joint Resources Committees that the region could be short by 18 days worth of gas, or roughly 3 billion cubic feet, depending on how cold the season gets.
For decades, "the house has gas heat" has been close to the safest sentence a buyer could hear in Anchorage. It meant predictable bills, a familiar system, nothing exotic to explain to a lender or an inspector. That assumption is still true today. It may not be true for much longer, and the shift is happening on a timeline measured in months, not decades. If you're comparing homes right now, the heating system deserves a longer look than it's gotten in years.
The Shortage Behind the Sudden Urgency
The reason that calculus is worth revisiting isn't speculation. It's the specific, dated events piling up over the past several weeks. Enstar had been counting on new supply from the Cosmopolitan gas field to start flowing by September 1, a deadline now just over a week away, and Sims has told lawmakers it isn't on track. Enstar is also in arbitration with Cook Inlet producer HEX Operating over a contract dispute involving what's called discretionary gas, the supply beyond a guaranteed minimum that Enstar needs to refill storage before winter. Meanwhile, in July, the Regulatory Commission of Alaska rejected Enstar's request to build a new storage facility in Cook Inlet, a $240 million project that would have held 25 billion cubic feet, close to half the utility's annual demand, saying Enstar hadn't provided enough information to justify it.
Enstar is now paying its main supplier, Hilcorp, $8.78 per thousand cubic feet under an existing contract, and has offered $17.50 per thousand cubic feet, roughly double, to any producer willing to drill and sell more. Nobody has taken the offer. As Sims put it at a press conference at Anchorage City Hall in late July, the utility is looking at liquefied natural gas imports as a backstop, at prices around $22 per thousand cubic feet against the roughly $10.80 it pays today. Mayor Suzanne LaFrance, standing alongside Sims at that same event, put it plainly: "Energy costs hit every single household budget in our community."
Some of that pressure has already reached bills. The delivery portion of an Enstar bill rose roughly 23 percent starting in July 2025, and in a separate filing that same year, Enstar sought another 11 percent increase in the wholesale cost of the gas itself. The long-term fix that gets discussed most often, the $55 billion Alaska LNG pipeline project from developer Glenfarne, could theoretically bring North Slope gas to Southcentral as early as 2029 if it's built. The legislature's latest attempt to pass the tax incentives the developer says are necessary fell apart this month, its third failed special session on the topic. Whatever solves this permanently is still years away at best.
What to Actually Ask Before You Write an Offer
If you're comparing two homes that otherwise look similar, the heating system is worth a specific conversation rather than a passing glance. A few questions worth raising directly with the seller or their agent:
- Ask for actual Enstar billing history if the seller has it, not just an estimate. A winter's worth of statements tells you more than a listing description ever will.
- Find out the age and condition of the furnace or boiler, and whether it's been serviced on a regular schedule.
- Ask whether there's a backup heat source already in place, a wood stove, a secondary system, anything that reduces total reliance on gas during a supply-constrained winter.
- If a heat pump has already been added, ask how it's configured, whether it's supplemental or primary, and how the seller has used it.
- For homes on larger lots outside gas-served areas, confirm the current heating fuel and delivery arrangement rather than assuming.
None of this is about avoiding gas-heated homes. Most Anchorage housing stock is gas-heated, and that isn't changing this year or next. It's about treating the heating system as a real variable in your decision and your negotiation, rather than a box that's already checked the moment you see a furnace in the mechanical room.
A Few Questions I Hear Often
Does this mean I shouldn't buy a home with gas heat in Anchorage right now? Not at all. Gas still heats the overwhelming majority of homes here, and that isn't going to reverse on any near-term timeline. The point is to ask the same specific questions about fuel type, system age, and cost history that you'd ask about a roof or a foundation, rather than assuming the answer doesn't matter.
If I'm selling this fall, should I install a heat pump first? For most sellers, no, not purely as a listing strategy. The economics still favor gas for typical households today, per the UAA research. Where it makes more sense is for owners who plan to stay long enough to see the cost gap close, or who want the backup and cooling capability heat pumps provide regardless of the fuel math.
This is exactly the kind of shift that rewards a buyer or seller who has someone watching the utility filings and legislative sessions on their behalf, not just the comparable sales.
