Today's Setup
the board in one read1,345 MW of U.S. nuclear is offline (1.4% of the fleet), down 93 MW from yesterday. Henry Hub gas is $2.82/MMBtu (cheap), so a supply loss has less price upside than usual. No ISO is forecast tight tomorrow, so losses would be largely absorbed. Biggest 30-day swing: MISO availability down 5.3 pts.
