Natural Gas Storage: +56 Bcf

Mild weather limited demand and allowed for an above-average build to start August.

The U.S. Energy Information Administration reported a weekly injection of 56 Billion Cubic Feet (Bcf) in Lower 48 natural gas storage inventories for the week ending August 8, 2025 (Link).  Total inventories now stand at 3,186 Bcf, 79 Bcf (2.4%) below year-ago levels and 196 Bcf (6.6%) above the 2020-2024 average for the same week. 

The weekly addition into natural gas storage reported today landed in line with consensus expectations as market participants had been looking for a larger-than-normal build resulting from widespread mild temperatures that weighed on natural gas demand for power generation during the report week. The reported 56-Bcf build highlighted the role heat plays in driving natural gas demand during summer, especially when contrasted with the previous week’s paltry 7-Bcf injection that coincided with intense heat across major population centers. The outsized build reported today helped to narrow the deficit to year-ago levels to only 79 Bcf, the closest 2025 inventories have been to the corresponding week in 2024 since January. The surplus to the five-year average for the same week increased and is also at a level last seen in January.
