CAISO’s EDAM Is Not Just a Market Change. It’s an Operational Shift.

Website - CAISO EDAM Resources

The Extended Day-Ahead Market (EDAM) of the California Independent System Operator (CAISO) expands day-ahead optimization across the west, introducing:

 New day-ahead bidding and scheduling workflows

 New congestion, uplift, and transmission constructs

 New settlement determinants and cost allocation rule

 Financially binding outcomes one day ahead

Your EDAM success depends on more than compliance—it requires a system that can absorb market evolution without disruption, eliminate manual, error-prone workflows, and deliver transparent, auditable financial outcomes.
