In early 2026 several major Colorado Utilities will be joining the Southwest Power Pool’s (SPP) Regional Transmission Organization (RTO) as it expands into the Western Interconnection. The SPP will bring an organized market to Colorado and nearby states with the benefits of increased reliability and better economics, with a Brattle Group study predicting $49 million in annual savings. We will be joined by Steve Johnson of the SPP who will discuss what this means for Colorado utilities and ratepayers.
