Winter storm conditions risk shuttering Appalachia gas wells and pipelines in bitter cold, potentially forcing more electricity outages in the East. PJM warned that pressure will mount across regional grids as the nation's largest grid operator exports power while managing unprecedented demand.

A massive winter storm brought power outages to over 780,000 customers across the South and East, with PJM Interconnection forecasting record peak demand of 147,000 MW. The deep freeze threatens to cripple natural gas infrastructure and test regional grids serving tens of millions of Americans.

Avangrid activated the New England Clean Energy Connect transmission line, delivering 1,200 megawatts of Canadian hydropower to Massachusetts with potential benefits for Connecticut ratepayers.
