Glustrom v. Colorado Public Utilities Commission
Annotate this CaseWith the approval of the Public Utilities Commission (PUC), in 2005 the Public Service Company of Colorado (Xcel) began constructing a coal-fired electric power unit known as "Comanche 3." When Xcel sought to recover a portion of its construction costs nearly four years later in a rate proceeding, Petitioner Leslie Glustrom intervened. Petitioner sought to introduce testimony that Xcel acted improperly and, consequently, should not recover its costs. The PUC excluded most of her testimony, a ruling that Petitioner challenged. Petitioner separately challenged the depreciation rate and the possibility that Comanche 3 might not be "used and useful" at the time rates went into effect. The PUC denied her challenges, and the district court affirmed. Upon review, the Supreme Court held that the PUC did not abuse its discretion when it struck substantial portions of Petitioner's testimony pursuant to the Colorado Rules of Evidence. Further, the depreciation rate approved by the PUC was established pursuant to law and in accordance with the evidence. Lastly, the PUC was free to exercise its discretion in departing from a strict application of the "used and useful" principle. Petitioner failed to meet her burden in showing why such a departure here would result in a rate that is unjust and unreasonable in its consequences.
