UPDATE 1-US natgas prices edge up to 14-week high on lower output, Texas heat

(Adds latest prices) By Scott DiSavino May 7 (Reuters) - U.S. natural gas futures rose about 1% to a 14-week high on Tuesday on a decline in output, an increase in feedgas to liquefied natural gas (LNG) export plants and forecasts for hot weather in Texas that should boost air conditioning demand. Limiting gains was a forecast calling for demand to decline more than expected over the next two weeks and an ongoing oversupply of gas in storage. Analysts forecast gas stockpiles were about 34% above normal for this time of year. Front-month gas futures for June delivery on the New York Mercantile Exchange rose 1.2 cents, or 0.5%, to settle at $2.207 per million British thermal units (mmBtu), their highest close since Jan. 29 for a third day in a row. That kept the front-month in technically oversold territory for a third straight day for the first time since January 2024. U.S. gas production was down about 11% so far in 2024 after several energy firms, including EQT and Chesapeake Energy , delayed well completions and cut back on other drilling activities after prices fell to 3-1/2-year lows in February and March. EQT is currently the biggest U.S. gas producer and Chesapeake is on track to become the biggest producer after its merger with Southwestern Energy. In the spot market, meanwhile, U.S. power and gas prices turned negative in Texas, California and Arizona as pipeline maintenance trapped gas in the Permian Shale in West Texas amid low demand for energy and ample hydropower in the West. In Texas, the Electric Reliability Council of Texas (ERCOT) issued a Weather Watch for Wednesday "due to unseasonably high temperatures, high levels of expected maintenance outages during the spring shoulder months, and the potential for lower reserves." SUPPLY AND DEMAND Financial firm LSEG said gas output in the Lower 48 U.S. states fell to an average of 96.9 billion cubic feet per day (bcfd) so far in May, down from 98.1 bcfd in April. That compares with a monthly record of 105.5 bcfd in December 2023. On a daily basis, output was on track to drop by around 3.1 bcfd over the past four days to a preliminary 15-week low of 94.7 bcfd on Tuesday. Meteorologists projected weather across the Lower 48 states would go from mostly near normal now through May 14 to warmer than normal from May 15-22. LSEG forecast gas demand in the Lower 48, including exports, would slide from 92.6 bcfd this week to 90.4 bcfd next week. Those forecasts were lower than LSEG's outlook on Monday. Gas flows to the seven big U.S. LNG export plants rose from an average of 11.9 bcfd in April to 12.4 bcfd so far in May with the return of Freeport in Texas from maintenance and inspection work. That compares with a monthly record of 14.7 bcfd in December. The amount of gas flowing to the 2.1-bcfd Freeport plant was on track to hold near a two-month high of 1.4 bcfd for a third day in a row on Tuesday, up from an average of 0.4 bcfd in April.
