An arctic blast pushed natural gas spot prices to a record $175 per dekatherm in North Carolina and Virginia, up from about $3 average, after temperatures fell below 10 degrees in Charlotte.

The spike is driven by transport bottlenecks rather than supply shortage, so it signals regional delivery constraints that can recur during cold snaps and lift Southeast energy costs.
