Natural Gas
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.
Final estimates for week ending 1/9/26 were for a withdrawal in the 90 to 91 Bcf range.
The total net withdrawal came in way below the final estimates, with 71 Bcf being taken out of storage.
Storage is now 33 Bcf above last year, and 106 Bcf above the 5-year average, which is within the 5-year historical range.
