Largest U.S. power grid currently in emergency. Live nationwide temperature map.

(Bloomberg) — A deep freeze is gripping the US in the wake of the worst storm so far this season, leaving the country’s biggest electric grid in emergency status and bracing for record wintertime demand.

PJM Interconnection LLC, which serves 67 million people from New Jersey to Chicago, issued a grid emergency for Tuesday and warned demand may exceed record levels for winter. With another burst of frigid air expected Friday, electricity demand could continue to test the system through the end of the month.

PJM generation outages surge
Spot electricity prices rise to several hundred dollars per MWH
BOSTON/HOUSTON, Jan 25 (Reuters) – Power plant outages surged along the eastern United States on Sunday as constricted natural gas supplies and frigid temperatures cut the electricity output of the region’s generation fleet.
The PJM Interconnection, the largest U.S. regional grid that serves 67 million people in the East and Mid-Atlantic, reported nearly 21 gigawatts of generation outages, with most of that capacity being forced offline. Those outages represented about 16% of PJM’s Sunday afternoon demand of 127.4 GW.
