Frigid Temps Cut U.S. Natural Gas Supply as Demand Soars, Texas Faces Possible Shortfall

(Reuters) — U.S. natural gas output fell to a preliminary 11-month low on Sunday as frigid weather froze wells across the country, while gas demand for heating and power generation was on track to hit record highs.

In Texas the state's power grid operator, the Electric Reliability Council of Texas (ERCOT), forecast electric demand on Tuesday would top last summer's all-time high and warned power supplies could fall short on both Monday and Tuesday.

ERCOT on Sunday issued an appeal to the public calling for energy conservation from 6 a.m. – 10 a.m. CT (1200-1600 GMT) on Monday.

The operator asked Texas government agencies to implement all programs to reduce energy use at their facilities during that time.

"Operating reserves are expected to be low Monday morning due to continued freezing temperatures, record-breaking demand, unseasonably low wind," the grid operator said in a statement.

The drop in U.S. gas availability so far this week was the most in over a year, with supplies on track to fall by around 9.6 billion cubic feet per day (Bcf/d) from Jan. 8-14 to an estimated 11-month low of 98.6 Bcf/d on Jan. 14, according to data from financial firm LSEG.

That decline so far was small compared with gas supply losses of around 19.6 Bcf/d during Winter Storm Elliott in December 2022, and 20.4 Bcf/d during the February freeze of 2021.

In North Dakota, oil production was down by an estimated 250,000 to 280,000 barrels per day due to freezing weather, while gas output had fallen by 700 million to 800 million cubic feet per day, according to North Dakota Pipeline Authority.

Electricity supply and demand forecasts can change quickly, however, as power plant availability and weather patterns develop. The February 2021 freeze left millions in Texas without power, water and heat for days and resulted in over 200 deaths as ERCOT scrambled to prevent a grid collapse after an unusually large amount of generation shut.

Some of those power plants shut because they could not access enough gas supplies after frigid temperatures froze wells and other equipment, known in the energy industry as freeze-offs.

Demand Soars

U.S. gas demand, including exports, will reach 164.6 Bcf/d on Jan. 15 and 171.9 Bcf/d on Jan. 16, according to LSEG.

Those daily demand forecasts would top the current all-time high of 162.5 Bcf/d set in December 2022 during Winter Storm Elliott, federal energy data from S&P Global Commodities Insights showed.

In Texas, ERCOT forecast power demand would peak at around 85,564 megawatts (MW) on Jan. 16 at around 8 a.m. local time, which would top the current all-time peak of 85,508 MW set in August 2023.

ERCOT estimated power use could top supplies by around 1,000 MW during the mornings of both Jan. 15 and Jan. 16. Those estimates, however, are subject to change and do not account for steps the grid operator may take to boost supplies and reduce demand.

One of the states hardest hit by the freeze over the past few days is Oregon, where roughly 164,000 homes and businesses were without power on Sunday, according to PowerOutage.us.

Portland General Electric, the state's biggest power company, said in a post on social media platform X that restoration efforts would continue through the weekend. Portland General had about 126,000 customers still without power at midday on Sunday.

Next-day power prices at the Mid-Columbia (Mid-C) hub at the Washington-Oregon border soared to a record high of around $1,075 per megawatt hour (MWh), according to LSEG data going back to 2010.

That compares with Mid-C averages of $81 per MWh in 2023 and $52 from 2018 to 2022.

Northwest Pipeline, which supplies gas to states including Washington, Oregon, Idaho, Wyoming, Utah and Colorado, on Saturday declared force majeure following an outage at a gas storage facility but has since resumed operations, company notices said.

Officials at U.S. energy company Williams Cos, the pipeline's owner, said on Sunday challenges on the pipeline had been resolved and that its transmission systems were continuing to transport scheduled volumes.
