A Quarter of Americans at Risk of Winter Power Blackouts, Grid Emerge…

Large swaths of North America are at risk of blackouts and other energy emergencies during extreme cold conditions this winter, along with potential disruptions of power-plant fuels, according to a US regulatory agency.
The electric grids at most risk of supply shortfalls are in Texas, the central US system stretching from the Great Lakes to Louisiana, New England and the Carolinas, the North American Electric Reliability Council said in its seasonal assessment Thursday. Severe weather may stress grids by causing demand to soar while supplies of natural gas, coal and back-up fuel oil are all tight, leaving little room for error, according to the report.
The central US grid managed by the Midcontinent Independent System Operator has tight power supplies after a large number of generators shut last winter and its Gulf Coast plants haven’t done enough to protect against cold weather, NERC said. New England’s perennially constrained gas supplies are even more strained this year because Europe is scrambling for every molecule of the fuel to keep warm.
NERC’s warning touches at least a quarter of Americans, who are poised to see already high utility bills soar even more this winter. Electricity demand has rebounded faster than anyone anticipated after the Covid-19 pandemic shutdowns. Prices of gas, the No. 1 power-plant fuel in the US, are high because of below-average stockpiles and strong exports to Europe as Russia wages a war on Ukraine. A possible railroad strike also threatens to impact coal supplies.
Overall, though, the report is less dire than the one heading into last winter. The outlook for winter hydropower generation in the West has improved and the Southwest Power Pool has added new gas and wind generation. In Texas, efforts to prepare the gas infrastructure and power plants does reduce the risk of a repeat of the widespread blackouts during February 2021 that lasted for days and left more than 200 people, NERC said.
Remember: three blasts for white walkers.
