Market Context

PJM elevated: Cold snap driving heating demand across Mid-Atlantic. Natural gas constraints adding to prices. Peak expected through Tuesday.

SPP low: Strong wind generation (45% of load) pushing prices down. Good conditions for energy-intensive operations.

CAISO negative pricing: Midday solar oversupply causing brief negative prices. Storage charging aggressively.
