Every day, power market participants in the Western US must determine how much electricity they need for the following day and where it's going to come from. In response, California's grid operator on May 1 launched its Extended Day-Ahead Market, or EDAM, giving power providers a better way to coordinate to find the cheapest electricity. So how is it going so far? And what does it mean for grid reliability, emissions, ratepayers and power traders? Joining the podcast to address those questions will be Elliott Mainzer, president and CEO of the California Independent System Operator, and Scott Miller, executive director of the Western Power Trading Forum. They are interviewed by Kassia Micek, a reporter for S&P Global Energy who covers Western power markets, who joins co-host Dan Testa to talk about what's ahead for the region.
