Western States Implement Extended Day-Ahead Market to Enhance Energy Planning
Western states in the U.S. are launching a new regional energy market known as the Extended Day-Ahead Market (EDAM). This initiative allows utilities to plan power demand a day in advance, leveraging forecasts of renewable energy sources like wind and solar. The system builds on an existing real-time electricity trading market that has been operational since 2014. According to supporters, this market has already saved customers nearly $7 billion by enabling utilities to trade excess power in short time windows before demand spikes. The new market aims to provide utilities with more time to plan, thus improving the balance of supply and demand, especially during extreme weather events. Rocky Mountain Power, Wyoming's largest utility, is among the first participants, with more Western utilities expected to join in the coming years.
