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 4/4/25 were for an injection in the 57 to 58 Bcf range.

The total net injection was in line with the final estimates, with 57 Bcf being put into storage. 

Storage is now 450 Bcf below last year, and 40 Bcf below the 5-year average, which is within the 5-year historical range.
