Business Context and Reporting Period
This Form 8-K is a current report filed by Ameren Corporation and Union Electric Company (Ameren Missouri) on July 1, 2016. The filing details a regulatory event where Ameren Missouri submitted a request to the Missouri Public Service Commission (MoPSC) to increase annual electric service revenues.
Key Financial Metrics and Request Details
- Revenue Request: Ameren Missouri seeks approval to increase annual revenues by $206 million, representing an average 7.8% increase in base rates.
- Infrastructure Investment: The request includes $74 million related to nearly $1.4 billion in gross electric infrastructure investments placed in service since the last rate case true-up date.
- Cost Components: The $74 million infrastructure recovery includes $39 million for depreciation, $25 million for return on rate base, and $10 million for increased property taxes.
- Volume and Transmission Impacts: The request includes $51 million to offset reduced customer sales volumes (primarily due to Noranda Aluminum idling) and $34 million for increased transmission charges.
- Expense Adjustments: The filing reflects decreases in pension and post-employment benefit expenses ($24 million) and solar rebate expenses ($15 million), offset by increased net energy costs ($23 million) and income taxes ($15 million).
- Rate Base and Return: The request is based on a $7.2 billion electric rate base and a 9.9% return on equity with a capital structure of 51.8% equity.
- Lost Cost Recovery: Ameren Missouri requested amortization over ten years of an estimated $81 million in lost fixed cost recovery due to lower sales from Noranda between April 2015 and May 2017.
Material Changes and Regulatory Context
The primary material change is the filing of a new electric rate case following the idling of operations at Noranda Aluminum's smelter in March 2016 and Noranda's subsequent Chapter 11 bankruptcy filing. Ameren Missouri states it has not and will not fully recover its revenue requirement until rates are adjusted to reflect Noranda's actual sales volumes. The filing also requests the continued use of existing regulatory tracking mechanisms for fuel, purchased power, pension, and tax positions, plus a new tracking mechanism for transmission charges.
Outlook, Risks, and Contingencies
Timeline: The MoPSC proceeding is expected to last up to 11 months, with a decision anticipated by late April 2017 and new rates effective in late May 2017.
Uncertainties: Ameren Missouri cannot predict the final approved rate increase, the effective date, or whether the approved increase will be sufficient to recover costs and earn a reasonable return.
Key Risks: The filing highlights significant risks including regulatory actions, changes in laws, technological advances affecting demand, fuel cost volatility, capital market disruptions, and the specific financial impact of Noranda's bankruptcy and smelter idling. Additional risks include environmental regulations, cyber attacks, and equipment failures.
