Extreme cold is forecast to cause significant disruptions to U.S. natural gas production, potentially cutting daily output by around 10%. This supply crunch has triggered a sharp rise in the price of benchmark natural gas futures at Henry Hub in Louisiana, which saw its biggest weekly increase since 1990—soaring 59% on Friday. Consequently, some residential consumers, including those in Pa., may face higher utility bills, with the timing and degree of impact varying by utility. Analysts expect large withdraws of natural gas from storage in the weeks ahead.
