Weekly briefing
Nuclear Supply Outlook
Week of Jul 30, 2026 · auto-generated each Monday from the morning data. Nuclear availability 99.6; ERCOT/SPP tight.
The number
The U.S. nuclear fleet sits at a Nuclear Availability Index of 99.6, little changed on the week, with 417 MW offline, 0.4% of capacity.
Market context
Henry Hub gas is $2.63/MMBtu (cheap), which scales how much a supply loss moves power price. The grid looks tight tomorrow in ERCOT, SPP, where a nuclear loss would bite hardest.
The weeks ahead (which units come off line next, with dates) and the overrun risk watch are part of NukeGryd Individual and up.
