Extended Day-Ahead Market (EDAM)
Building on the demonstrated economic, reliability, and environmental benefits of the Western Energy Imbalance Market (WEIM), the California ISO’s EDAM will optimize the use of existing transmission and resources in the much larger day-ahead timeframe across an expanded Western footprint.
EDAM will open the door to significantly improved economic benefits through the commitment of least-cost generation across the market’s broad geographic footprint and enable improved situational awareness across balancing authority areas, enhance reliability, and lower greenhouse gas emissions.
Currently, four entities have informed the ISO of their interest in joining the EDAM:
PacifiCorp,
Balancing Authority of Northern California,
Portland General Electric,
Los Angeles Department of Water & Power. Two additional entities, Idaho Power and
NV Energy, have indicated that they are leaning toward EDAM as their preferred day-ahead market.
