With a surge in interconnection requests from large load customers, Public Service Company of Colorado has fallen behind on processing applications, a situation that has sparked concern from state regulators.

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.
