US natgas prices climb 3% on record LNG flows, lower daily output

U.S. natural gas futures climbed about 3% to a one-week high on record flows to liquefied natural gas export plants and a decline in daily output, Reuters reported.

On its first day as the front month, gas futures for May delivery on the New York Mercantile Exchange rose 11.5 cents, or 2.9%, to settle at $4.065 per million British thermal units, their highest close since March 19.

For the week, the contract was up about 2% after sliding about 3% in the prior week.

Mild weather and low demand through mid-April should allow utilities to keep adding gas to storage in coming weeks with some analysts saying stockpiles were on track to increase in March for the first time since 2012 and only the second time in history.

Gas stockpiles, however, were still about 5% below normal levels for this time of year after extremely cold weather in January and February forced energy firms to pull large amounts of gas out of storage, including record amounts in January. [EIA/GAS] [NGAS/POLL]

Mild weather and ample hydropower in the U.S. West caused spot power prices at the South Path 15 (SP-15) hub in Southern California to turn negative for the first time since June 2024. Power prices at SP-15 first fell into negative territory in 2024, averaging below zero on 18 days last year, according to data from financial firm LSEG going back to 2001.

Next-day prices at SP-15 fell to minus $5.23 per megawatt hour. That compares with an average of $28.05 so far in 2025, $31.30 in 2024 and an average of $58.87 during the prior five years (2019-2023).

At the Mid-Columbia hub in Oregon, meanwhile, next-day power prices dropped to $6.57 per MWh, their lowest since May 2023.

SUPPLY AND DEMAND

Financial firm LSEG said average gas output in the Lower 48 U.S. states rose to 106.0 billion cubic feet per day so far in March from a record 105.1 bcfd in February.

On a daily basis, however, output was on track to drop about 2 bcfd over the past four days to a preliminary one-week low of 105.2 bcfd on Friday. Traders noted preliminary data was often changed later in the day.

Meteorologists projected temperatures in the Lower 48 states would remain mostly warmer than normal through April 12.

LSEG forecast average gas demand in the Lower 48, including exports, will slide from 108.5 bcfd this week to 102.9 bcfd next week before edging up to 103.3 bcfd in two weeks. The forecasts for this week and next were lower than LSEG’s outlook on Thursday.

Gas flowing to the eight big operating U.S. LNG export plants rose to an average of 15.8 bcfd so far in March, from a record 15.6 bcfd in February, as new units at Venture Global’s 3.2-bcfd Plaquemines LNG plant under construction in Louisiana entered service.

The U.S. became the world’s biggest LNG supplier in 2023, surpassing Australia and Qatar, as surging global prices fed demand for more exports due in part to supply disruptions and sanctions linked to Russia’s 2022 invasion of Ukraine.

Gas traded around $13 per mmBtu at both the Dutch Title Transfer Facility (TTF) benchmark in Europe and the Japan Korea Marker (JKM) benchmark in Asia.
