US natgas prices hold steady as tropical storm lowers demand outlook

LSEG said average gas output in the U.S. Lower 48 states rose to 110.5 billion cubic feet per day (bcfd) so far in July, up from 110.0 bcfd in June, but remained below the monthly record high of 110.6 bcfd in December 2025.

Analysts said mostly mild weather during the spring allowed energy firms to stockpile more gas than usual. As they wait for a federal report on Thursday, analysts projected the amount of gas in storage likely rose to 6.5% above normal during the week ended July 17, up from 6.4% above normal during the previous week.

Meteorologists forecast the weather would remain mostly warmer than normal through August 5, forcing power generators to continue burning lots of gas to keep air conditioners humming. About 40% of U.S. power generation comes from gas-fired plants.

LSEG projected average gas demand in the Lower 48 states, including exports, would rise from 111.0 bcfd this week to 111.6 bcfd next week. The forecast for this week was lower than LSEG's outlook on Friday, while its forecast for next week was higher.
