Detailed Narrative
2024 Performance and Strategic Execution
Ameren achieved its key business objectives in 2024, investing approximately $4.3 billion in infrastructure and delivering adjusted earnings of $4.63 per share, surpassing its guidance midpoint. The company's strategic investments led to improved reliability, with grid improvements preventing over 3.5 million minutes of potential outage time during severe winter storms. This performance underscores the effectiveness of its 3-pillar strategy focused on infrastructure investment, regulatory advocacy, and operational optimization.
Economic Development and Sales Growth
The company anticipates significant economic growth opportunities, particularly from data centers, across its service territories. This has led to a revised weather-normalized retail sales growth expectation of 5.5% compounded annually from 2025 through 2029 for Ameren Missouri, a substantial increase from prior flat to 0.5% expectations. Ameren has signed construction agreements for 1.8 GW of new data center load, with a total capacity to serve 2 GW by 2032 and more thereafter.
Capital Investment Plan and Rate Base Growth
Ameren is rolling forward a robust 5-year capital plan of $26.3 billion for 2025-2029, representing a 20% increase over the previous plan. This plan is expected to drive a 9.2% compound annual rate base growth from 2024 through 2029. The increase primarily reflects accelerated generation needs to meet updated sales growth expectations and includes investments in Ameren Missouri's Smart Energy Plan, Ameren Illinois's Multi-Year Rate Plan, and MISO long-range transmission projects.
Missouri Resource Planning and Generation Strategy
In response to significant sales growth potential, Ameren Missouri updated its Preferred Resource Plan, aiming to serve 1.5 GW of additional demand by 2032. The revised plan calls for accelerating and expanding natural gas generation and battery storage, accelerating solar generation investment, potentially extending the life of the Sioux Energy Center, and investing in additional nuclear generation by 2040. This represents an addition of 2.3 GW of generation capacity by 2035 and approximately $7 billion of increased investment by 2035 compared to the 2023 IRP.
Transmission Opportunities
MISO approved a nearly $22 billion Tranche 2.1 portfolio, with Ameren selected to lead $1.3 billion worth of projects in Missouri and Illinois. An additional $6.5 billion of projects in the portfolio, including $1.8 billion in Illinois, will be open for competitive bid, for which Ameren believes it is well-positioned. Further Tranche 2.2 projects are expected to be developed, indicating a robust long-term transmission investment pipeline.
Regulatory and Legislative Landscape
Ameren is actively engaged in Missouri's legislative session, advocating for bills like the Power Predictability and Reliability Act and the Missouri First Transmission Act, which aim to support reliable energy and economic growth. The company also awaits a decision from the Missouri PSC on its 2024 electric rate review by May and plans to file for approval of a modified industrial tariff by Q2. In Illinois, the ICC approved the Multi-Year Rate Plan for 2024-2027, providing clarity on future investments.
Financing Strategy and Balance Sheet
To fund its robust investment plan, Ameren expects to issue approximately $600 million of equity annually from 2025 through 2029, partly through dividend reinvestment and employee benefit plans. The company also plans debt issuances totaling $500 million in Ameren Missouri, $650 million in Ameren Illinois, and $750 million at Ameren Parent in 2025. This financing strategy is designed to maintain strong balance sheet and credit ratings, with FFO to debt metrics expected to support Baa1/BBB+ ratings.
