The U.S. Energy Information Administration (EIA) reported that underground natural gas storage capacity for the Lower 48 states has remained relatively unchanged in 2019. Design capacity, which is the engineering estimates, has held consistent near 4.6 Tcf. Demonstrated peak capacity which is calculated as the total of the highest storage levels reached by each storage facility during any month during the most recent five-year period has declined slightly to ~4.4 Tcf. Michigan has the largest design capacity at 684 Bcf with Texas close behind at 526 Bcf. For the sixth year in a row, no new storage fields were completed. Click the link below to read more.
