US energy companies added 64 billion cubic feet of natural gas to storage during the week ending September 25, 2026, matching expectations but remaining below the five-year average build of 80 bcf. Total inventories reached 3.415 trillion cubic feet, 3.9% below year-ago levels and about 2.4% above the five-year average for the period. Natural gas prices fell below $3.00 per MMBtu to a one-week low as traders weighed record Lower 48 production and mostly mild weather against stronger LNG feedgas demand. Preliminary estimates indicate a further 79 bcf storage build for the week ending October 2.
