GridU Webinar: Two Markets, One Grid What EDAM and Markets+ Mean for the West

The Western electricity market is undergoing its largest transformation in decades. CAISO’s Extended Day-Ahead Market (EDAM) and SPP’s Markets+ represent competing regional frameworks designed to improve dispatch efficiency, integrate renewable resources, and share reliability across a wider geographic footprint. These markets will impact scheduling practices, transmission usage, congestion costs, resource adequacy planning, and operational risk management. This webinar explains what these markets are, why they are being created, and what participation means for utilities, public power agencies, and energy market participants. We will walk through how the markets operate, how they differ, and how they may affect costs, reliability, resource adequacy, congestion, and operational risk.
