Underground storage capacity for natural gas in the United States has stayed essentially flat between 2012 and 2020, and was little changed from 2019 to 2020, the U.S. Energy Information Administration (EIA) said on Thursday. Last year, design capacity, or the total working natural gas capacity for all active facilities in the Lower 48 states, rose by 4 billion cubic feet (Bcf), or by 0.1 percent compared to 2019. Demonstrated peak capacity, or the total of the highest storage levels reached by each storage facility during any month during the most recent five-year period, dropped by 8 Bcf in 2020 versus 2019, or by 0.2 percent, according to the EIA estimates. The largest regional annual change in either measure of underground natural gas working storage capacity was a decrease in demonstrated peak capacity in the Pacific region. In terms of design capacity, the increases last year occurred primarily in […]
