Tight Spring Loads and Western Market Expansion

Wholesale power markets for the seven-day period ending May 29, 2026, reflected typical shoulder-season conditions, with a clear regional split between modest prices in Western and central markets and firmer prices in parts of the East. CAISO and the broader Western Energy Markets footprint continued to publish daily real-time and EDAM materials, with prices shaped by steep net-load ramps, solar output, congestion, and EDAM's early operating phase. ERCOT, SPP, MISO, AESO, IESO, NYISO, and ISO-NE were generally orderly, while PJM stood out for stronger real-time pricing and continued market-design pressure tied to large-load growth, resource adequacy, and investment incentives.
