Scheduled to launch on May 1, 2026, EDAM will expand the benefits of day-ahead market coordination across the West, improving reliability and optimizing resources for millions of customers.
EDAM’s Role: Optimizing Western Resources for Reliability
PacifiCorp is a Portland-based grid operator serving six Western states. PacifiCorp CEO Cindy Crane highlighted the importance of this step forward:
“A modern, coordinated day-ahead market in the West is vital to optimizing the region’s energy resources so we can continue to provide reliable and affordable power to our 2 million electricity customers across six states.”
MCG Energy: Ready for Day One
At MCG Energy, we’re proud to play a role in this transformation. Our platform will be fully integrated with EDAM from day one, ensuring our customers are ready to participate seamlessly as the market goes live.
This milestone underscores the momentum toward a more connected, resilient, and cost-effective energy future—and we’re excited to help our partners lead the charge.
From Real-Time to Day-Ahead: EDAM’s Evolution
EDAM builds on CAISO’s Western Energy Imbalance Market (WEIM), which has already delivered real-time coordination across the West. EDAM further enables day-ahead energy trading and resource optimization across multiple balancing authorities—an expansion designed to:
⚡ Improve grid reliability and resource efficiency
💰 Lower costs through broader market access
🌎 Support renewable integration across the Western Interconnection
Onboarding timelines are mapped out for 2026 activation.
By combining our proven technology with EDAM’s expanded framework, MCG Energy is helping energy providers like PacifiCorp unlock greater efficiency, reliability, and sustainability across the West.
MCG Energy customers won’t just be ready for EDAM—they’ll be positioned to lead in a more connected and resilient energy future.
