Today's Setup
the board in one read417 MW of U.S. nuclear is offline (0.4% of the fleet), down 111 MW from yesterday. Henry Hub gas is $2.63/MMBtu (cheap), so a supply loss has less price upside than usual. The grid looks tight tomorrow in SPP (and 1 other ISO) on the demand forecast, where any nuclear loss would bite hardest. Biggest 30-day swing: NYISO availability down 1.0 pts.
