U.S. natural gas storage capacity has remained flat over the past eight years

Underground natural gas working storage capacity in the Lower 48 states has remained relatively flat since 2012. We measure natural gas working storage capacity in two ways: design capacity and demonstrated peak capacity. Both measures of capacity were relatively unchanged in 2020 compared with 2019: design capacity increased 0.1% and demonstrated peak capacity decreased 0.2%. The largest regional year-over-year change was a decrease in demonstrated peak capacity in the Pacific region. More »
