US Natural Gas Update: Prices Rise on Hotter Forecasts for the South and West

US natural gas prices pared gains in after-hours trading on Friday but ended the session in positive territory as forecasts for hotter weather raised expectations for stronger gas-fired power generation and increased air-conditioning demand.The front-month Henry Hub contract and the continuous contract rose by 0.80% to $2.755 per million British thermal units.The Commodity Weather Group said Friday that forecasts had shifted hotter, with above-average temperatures expected across Texas, the Southwest and the Interior West through Sept. 4.The expected heatwave caused the Electric Reliability Council of Texas, or ERCOT, the state's largest power grid operator, to forecast that electricity demand from Friday through Tuesday would exceed its all-time record set in July.Overall, US electricity generation also remained above year-ago levels. The Edison Electric Institute said Lower 48 electricity output in the week ended Aug. 15 rose 2.36% from a year earlier to 101,498 GWh. Output over the 52 weeks ended Aug. 15 increased 2.24% year on year to 4,359,446 GWh.At the same time, strong domestic gas production continued to weigh on the market. Barchart, citing BNEF data, estimated Lower 48 dry gas production at 113.1 Bcf/d on Friday, up 4.4% from a year earlier. Lower 48 state gas demand was estimated at 80.9 Bcf/d, 2.7% higher year on year.Net gas flows to US LNG export terminals were estimated at 17.7 Bcf/d, down 2.6% from a week earlier. Trading Key said export demand remains limited due to a maintenance turnaround at Freeport LNG and slow capacity ramp-ups at Golden Pass.The Energy Buyers' Report said the market's fundamental backdrop remained relatively soft despite Friday's rebound, with inventories still at healthy levels and cooling demand gradually losing seasonal support.The latest data from the US Energy Information Administration showed utilities added 16 Bcf to underground storage in the latest week, below both the 19 Bcf injection a year earlier and the five-year average injection of 29 Bcf.Total working gas in storage stood at 3,169 Bcf, down 28 Bcf, or 0.9%, from year-ago levels but 185 Bcf, or 6.2%, above the five-year average for the same week.
