“Blackouts could increase by 100 times in 2030 relative to today's averages if the U.S. continues to shutter reliable power plants and fails to add firm capacity: in the 'plant closures' scenario annual loss-of-load hours rise from 8.1 hours per year today to 817 hours — 'more than 800 hours per year' — with 104 GW of firm capacity set to retire by 2030 and an additional 100 GW of new peak-hour supply needed, 50 GW of it attributable to data centers.”

2030 is in the future, and the figure is a scenario-conditional modeling result (the 'plant closures' case); clean energy analysts have disputed the modeling assumptions.
