Topic What EDAM & DAME Mean for CAISO: Market Changes and Data Impacts

On May 1, CAISO’s Extended Day-Ahead Market (EDAM) and Day-Ahead Market Enhancements (DAME) will go live. Together, these changes represent a major shift in how the Western day-ahead market operates.

EDAM expands participation beyond California into a broader regional footprint, while DAME introduces changes to how the day-ahead market clears within CAISO.
