Today's Setup
the board in one read2,048 MW of U.S. nuclear is offline (2.1% of the fleet), up 882 MW from yesterday. Henry Hub gas is $2.79/MMBtu (cheap), so a supply loss has less price upside than usual. The grid looks tight tomorrow in SPP on the demand forecast, where any nuclear loss would bite hardest. Biggest 30-day swing: Florida Power & Light (FPL) availability down 26.9 pts.
