Can the Utah Public Service Commission regulate municipal utilities serving customers outside city boundaries? Heber Light & Power Co. v. Utah Public Service Commission Explained

In Heber Light & Power Co. v. Utah Public Service Commission, the Utah Supreme Court addressed whether the Public Service Commission has jurisdiction to regulate municipal interlocal entities that provide electrical service outside their municipal boundaries.

Background and Facts

Heber Light & Power Company, an interlocal entity comprised of several municipalities, had been providing electricity in the Heber Valley for nearly a century. Rocky Mountain Power, which held a Certificate of Public Convenience and Necessity for unincorporated Wasatch County, filed a complaint alleging that Heber Light was improperly serving customers outside its municipal boundaries within Rocky Mountain’s exclusive service territory. When Heber Light moved to dismiss for lack of subject matter jurisdiction, the Commission denied the motion, prompting Heber Light to seek extraordinary relief from the Utah Supreme Court.

Key Legal Issues

The court addressed two primary issues: whether the Commission’s order constituted final agency action subject to appellate review, and whether the Commission had statutory authority to regulate municipal interlocal entities providing electrical service beyond their municipal boundaries.

Court’s Analysis and Holding

The court found the Commission’s order was not final agency action under the three-part test, as it was merely a preliminary denial of a motion to dismiss. However, the court granted extraordinary relief because requiring Heber Light to participate in proceedings before an agency lacking jurisdiction would not constitute a “plain, speedy, and adequate remedy.” Applying principles of statutory interpretation, the court emphasized that administrative agencies possess only those powers expressly granted by statute. The Commission’s authority extends only to “public utilities,” and governmental entities organized under the Interlocal Cooperation Act do not fall within that definition. The 1989 legislative amendment specifically removing “governmental entities” from the definition of “person” in the public utility code demonstrated clear legislative intent to exclude such entities from Commission jurisdiction.

Practice Implications

This decision reinforces that Utah agencies cannot expand their jurisdiction beyond express statutory grants. When agencies act outside their authority, practitioners should consider seeking extraordinary relief rather than exhausting administrative remedies. The ruling also highlights the importance of careful statutory construction in determining agency jurisdiction, particularly when legislative history shows intent to limit agency authority over specific entities.
