Natural Gas Storage: +101 Bcf
EIA reports the second triple-digit build of the season.
The U.S. Energy Information Administration reported a weekly injection of 101 billion cubic feet (Bcf) into Lower 48 natural gas storage inventories for the week ending May 15, 2026 (Link). Total inventories now stand at 2,391 Bcf, 33 Bcf (6.6%) above year-ago levels and 149 Bcf (6.6%) above the 2021-2025 average for the same week.
Today’s storage report showed a net injection of 101 Bcf for the week ended May 15. This marks the second-largest build of the season so far, trailing only the 103-Bcf addition recorded four weeks prior. Storage inventories continued to grow at a faster pace than the five-year average while losing ground to year-ago levels. During the same week in 2025, inventories grew by 119 Bcf, meaning the surplus to that benchmark narrowed by 18 Bcf to its lowest point since February.
