Risk Factors Full Breakdown - Total Risks 20
- Manufacturing - Risk 1Our electric generation and electric and natural gas transmission and distribution facilities, including natural gas storage facilities, are subject to operational risks.
Our financial performance depends on the successful operation of electric generation and electric and natural gas transmission and distribution facilities, including natural gas storage facilities. Operation of these facilities involves many risks, including: - facility shutdowns due to operator error, or a failure of equipment or processes;- longer-than-anticipated maintenance outages;- failures of equipment that can result in unanticipated liabilities or unplanned outages;- aging infrastructure that may require significant expenditures to operate and maintain;- natural gas leaks or explosions near populated areas, including residential areas, business centers, industrial sites, and other public gathering places;- lack of adequate water required for cooling plant operations and to operate hydroelectric energy centers;- labor disputes;- disruptions in the delivery of electricity and natural gas to our customers;- inability to maintain reliability of our electric utility services as coal-fired energy centers are retired and renewable energy generation is placed in service, as well as our ability to meet generation capacity obligations, which could potentially increase if new data centers and/or other large primary service customers locate within our service territories;- disruptions to the global supply chain as a result of shortages for labor, materials, or equipment, tariffs and international trade relations, geopolitical conflict, delivery delays, and economic pressures, among other things;- suppliers and contractors who do not perform as required under their contracts, including those obligations that are affected by supply chain disruptions;- failure of other operators' facilities and the effect of that failure on our electric and natural gas systems and customers;- inability to comply with regulatory requirements or obtain permits, including those relating to environmental laws;- handling, storage, and disposition of CCR;- unusual or adverse weather conditions or other natural disasters, including but not limited to those that may result from climate-related risks, such as severe storms, droughts, wildfires, floods, tornadoes, earthquakes, icing, sustained high or low temperatures, solar flares, and electromagnetic pulses;- the level of wind and solar resources;- inability to operate wind generation facilities at full capacity resulting from requirements to protect natural resources, including wildlife, or other conditions limiting full capacity;- the occurrence of catastrophic events such as fires, explosions, acts of sabotage, which in recent years have increased in frequency and severity within the utility industry, acts of terrorism, civil unrest, pandemic health events, or other similar events;- accidents that might result in injury or loss of life, extensive property damage, or environmental damage;- ineffective vegetation management programs;- cybersecurity risks, including loss of operational control of Ameren Missouri's energy centers and our transmission and distribution systems and loss of data, including sensitive customer, employee, financial, and operating system information, through insider or outsider actions;- limitations on amounts of insurance available to cover losses that might arise in connection with operating our electric generation facilities, electric and natural gas transmission and distribution facilities, and natural gas storage facilities;- inability to implement or maintain information systems;- failure to keep pace with and the ability to adapt to rapid technological change, including generative and agentic artificial intelligence; and - other unanticipated operations and maintenance expenses and liabilities. The foregoing risks could affect the operations of our facilities, impede our ability to meet regulatory requirements, or expose us to an increase in litigation, which could increase operating costs, increase our capital requirements and costs, reduce our revenues, or have an adverse effect on our liquidity.
- Manufacturing - Risk 2Ameren Missouri's ownership and operation of a nuclear energy center creates business, financial, and waste disposal risks.
Ameren Missouri's ownership of the Callaway Energy Center subjects it to risks associated with nuclear generation, including: - potential harmful effects on the environment and human health resulting from radiological releases associated with the operation of nuclear facilities and the storage, handling, and disposal of radioactive materials;- continued uncertainty regarding the federal government's plan to permanently store spent nuclear fuel and, as a result, the need to provide for long-term storage of spent nuclear fuel at the Callaway Energy Center;- limitations on the amounts and types of insurance available to cover losses that might arise in connection with the Callaway Energy Center or other United States nuclear facilities;- uncertainties about contingencies and retrospective insurance premium assessments relating to claims at the Callaway Energy Center or other United States nuclear facilities;- public and governmental concerns about the safety and adequacy of security at nuclear facilities;- limited availability of fuel supply and our reliance on licensed fuel assemblies from primarily one NRC-licensed supplier of Callaway Energy Center's assemblies;- costly and extended outages for scheduled or unscheduled maintenance and refueling;- increased regulatory scrutiny and oversight resulting from more frequent outages;- uncertainties about the technological and financial aspects of decommissioning nuclear facilities at the end of their licensed lives;- the ability to continue to attract and retain qualified labor to operate the Callaway Energy Center;- the adverse effect of poor market performance and other economic factors on the asset values of nuclear decommissioning trust funds and the corresponding increase, upon MoPSC approval, in customer rates to fund the estimated decommissioning costs; and - potential adverse effects of a natural disaster, acts of sabotage or terrorism, including a cyber attack, or any accident leading to a radiological release. The NRC has broad authority under federal law to impose licensing and safety requirements for nuclear facilities. In the event of noncompliance, the NRC has the authority to impose fines or to shut down a unit, or both, depending upon its assessment of the severity of the situation, until compliance is achieved. Revised safety requirements promulgated from time to time by the NRC could necessitate substantial capital expenditures at the Callaway Energy Center. In addition, if a serious nuclear incident were to occur and result in serious injury, loss of human life, significant damage to property, environmental impacts, and impairment of our operations, it would adversely affect Ameren's and Ameren Missouri's results of operations, financial condition, and liquidity. A major incident at a nuclear facility anywhere in the world could cause the NRC to limit or prohibit the operation of any domestic nuclear unit and could also cause the NRC to impose additional conditions or requirements on the industry, which could increase costs and result in additional capital expenditures. While the Callaway Energy Center is in compliance with the current NRC standards relating to seismic design and risk, these standards also require Ameren Missouri to address periodic changes to seismic hazard data and evaluation methods for the impact of an earthquake on its Callaway Energy Center due to its proximity to a fault line, which could require seismic risk evaluation updates and installation of additional capital equipment.
