Differences Between Eastern and Western Grids

People in Power Episode 20: Abigail Sawyer talks with Carrie Simpson, vice president of markets for the Southwest Power Pool, about her experience in energy, which goes back to the early 2000s when she worked as an energy trader for Enron. Since then Carrie has been involved in power markets in both the Western and Eastern Interconnection. She is anticipating the expansion of SPP’s RTO—which will be the first organized wholesale market to operate in both interconnections—and also preparing for SPP’s day-ahead market offering, Markets+, which will begin serving entities in the Western Interconnection in October 2027.
