Business Context and Reporting Period
This Form 8-K was filed on July 3, 2014, by Ameren Corporation and its subsidiary Union Electric Company (Ameren Missouri). The filing reports a material event regarding Ameren Missouri's intention to file an electric rate case with the Missouri Public Service Commission (MoPSC).
Key Financial Metrics and Request Details
- Revenue Request: Ameren Missouri filed a request to increase annual revenues for electric service by $264 million.
- Rate Base: The request is based on an electric rate base of $7.3 billion.
- Capital Structure: The filing assumes a capital structure of 51.6% equity.
- Return on Equity: The request seeks a 10.4% return on equity.
- Plant Additions: Gross plant additions since the last rate order total $1.4 billion.
- Net Energy Costs: The request includes $127 million related to increased net energy costs above base rates.
Material Changes and Investment Drivers
The rate request seeks recovery for increased net energy costs, rebates for customer-installed solar generation, and a return on additional infrastructure investments. Key investments driving the request include:
- Upgrades to electrostatic precipitators at the Labadie energy center to meet environmental regulations.
- Replacement of the nuclear reactor vessel head at the Callaway energy center.
- Construction of two new substations in St. Louis.
- Development of the O'Fallon energy center, Missouri's largest investor-owned utility solar facility.
Outlook, Risks, and Regulatory Timeline
Timeline: The MoPSC proceeding is expected to last up to 11 months, with a decision anticipated by May 2015 and rates effective in June 2015.
Regulatory Mechanisms: Ameren Missouri requested continued use of the Fuel and Purchased Power Cost Recovery (FAC) mechanism, which allows rate adjustments for 95% of changes in net energy costs without a traditional rate proceeding.
Risks and Uncertainties: Management states it cannot predict the level of any approved rate change or whether it will be sufficient to recover costs. Key risks include regulatory actions, changes in laws, fuel cost volatility, environmental regulations, and potential asset impairments.
Investor Verification Checklist
- Verify the final MoPSC decision on the $264 million revenue increase request expected by May 2015.

- Track the status of the $1.4 billion in gross plant additions and their cost recovery approval.
