Narrative Opinion Summary
The case involves an appeal by Noranda Aluminum, Inc. and the Missouri Office of the Public Counsel against a decision by the Missouri Public Service Commission (PSC) that granted Union Electric Company, operating as AmerenUE, a significant increase in annual revenue from Missouri customers. The primary legal issues addressed include the determination of the appropriate capital structure and return on equity (ROE) for AmerenUE, the implementation of a Fuel Adjustment Clause (FAC), and the recovery of expenses related to vegetation management and infrastructure inspections. The PSC's decision was initially reversed by a circuit court but was ultimately affirmed upon review, with the court finding that the PSC acted within its lawful authority and that its findings were reasonable and based on substantial evidence. The appeals court upheld the PSC's determination of a 10.76% ROE, the approval of the FAC, and the treatment of depreciation rates and recovery of specific expenses. The court emphasized the Commission's broad discretion in rate-setting and the presumption of validity of its orders, requiring challengers to prove any unreasonableness or lack of lawfulness in the Commission's decisions. The outcome affirmed the PSC's order, allowing AmerenUE to implement the approved rate adjustments and expense recoveries.
