Public Service Company of Colorado and the Polis administration want to keep Unit 2 of the coal-fired Comanche Generating Station running a year longer than planned.

The Colorado PUC issued a split decision approving Public Service Company of Colorado’s application to join SPP’s Markets+, finding that market participation is in the public interest and will “provide a number of benefits.”

The development of SPP's Markets+ has picked up the pace with stakeholders agreeing on an interim governance structure and representation on the working groups that will handle much of the effort ahead.

The Colorado PUC voted to approve Public Service Company of Colorado's plans to join SPP’s Markets+, with commissioners split on whether the move is a step toward or away from full RTO participation.

Members of the Colorado PUC expressed differing opinions on whether PSCo joining Markets+ would be in the public interest.

With data centers contributing to surging load growth, a new report suggests that more Western utilities should adopt clean transition tariffs or even make the tariffs mandatory for certain large customers.

Tri-State asked the Colorado Public Utilities Commission to find it would be in the public interest for the power supplier to join SPP, saying integrating with the RTO would bring significant benefits.

The study, conducted by Aurora Energy Research, found EDAM could provide the Denver-based utility $11.2 million more in average annual savings from 2028 to 2040 compared with Markets+, rising to $13.2 million through 2060.
