3. Jurisdiction

The Commission's jurisdiction over the Advanced Metering Infrastructure (AMI) investment program arises from the utility's obligation to ensure that "[a]ll charges demanded or received by any public utility ... shall be just and reasonable"⁷ and from the statutory constraint that states that "no public utility shall change any rate ... except upon a showing before the commission and a finding by the commission that the new rate is justified."⁸ Since investment in a major program like AMI has substantial impacts on electric rates, the Commission's authority to review the costs and resulting rates is clear.

Similarly, the Commission has broad authority to modify its own decisions⁹ and the procedures for doing so are set forth in the Commission's Rules.¹⁰ When seeking to modify a decision, the request for modification:

... must concisely state the justification for the requested relief and must propose specific wording to carry out all requested modifications to the decision. Any factual allegations must be supported with specific citations to the record in the proceeding or to matters that may be officially noticed. Allegations of new or changed facts must be supported by an appropriate declaration or affidavit.¹¹
