Natural Gas
Storage Report
The amount of natural gas available for usage is very important in the energy industry because, among other things, it is used for heating, and as a main fuel source for generating electricity at power plants to be consumed by both homes and businesses. By comparing current levels of natural gas storage to the levels of last year and the past five years, an assessment as to the state of natural gas supplies to meet demand can be made.

The total net withdrawal for the week ending 2/20/26 was 52 Bcf.

Storage is now 141 Bcf above last year, and 177 Bcf above the 5-year average, which is now above the 5-year historical range.
