"US Faces Winter Blackout Risks From Data Centers’ Power Needs"

From Bloomberg, November 18:

Rising electricity demand from data centers is raising the risk of blackouts across a wide swath of the US during extreme conditions this winter, according to the regulatory body overseeing grid stability.

Power consumption has grown 20 gigawatts from the previous winter, the North American Electric Reliability Corp. said Tuesday in its winter assessment. A gigawatt is the typical size of a nuclear power reactor. Supply hasn’t kept up.

As as result, a repeat of severe winter storms in North America that unleash a polar vortex, of which there have been several in recent years, could trigger energy shortfalls across the US from the Northwest to Texas to the Carolinas. All regions have adequate resources in normal conditions.

“Data centers are a main contributor to load growth in those areas where demand has risen substantially since last winter.” Mark Olson, manager of the reliability assessment, said in an emailed statement.

America’s power grid has been facing rising blackout risks for years as aging infrastructure is increasingly stressed by severe storms and wildfires. Now the data center boom, driven by the spread of artificial intelligence, is adding to the strain by supercharging US electricity growth after being stagnant for two decades....
