Ameren Missouri investing in reliable energy for when customers need it most

As energy demand and threats of extreme weather rise, strengthening the energy grid is more important than ever

ST. LOUIS, June 10, 2024 /PRNewswire/ -- Ameren Missouri, a subsidiary of Ameren Corporation (NYSE:AEE), has filed an application with the Missouri Public Service Commission to build an 800 megawatt simple-cycle natural gas energy center to serve as a reliable backup source of energy, ready to use when customers need it most. The Castle Bluff Energy Center is designed to bolster grid reliability and would be used to deliver energy on the hottest summer days, the coldest winter nights, and complement the increasing amount of renewable energy generation being added to the grid.

Castle Bluff represents a potential investment of approximately $900 million. The identified site already has existing infrastructure and transmission line access, reducing overall construction time and cost to customers. With timely regulatory approval, construction is scheduled to begin in 2026, with the energy center expected to be ready to serve customers in 2027.

"Customers across the state count on the reliable, affordable energy Ameren Missouri provides around the clock, and Castle Bluff will be one of the ways we're going to be able to meet their needs in the future," said Mark Birk, chairman and president of Ameren Missouri. "The on-demand energy Castle Bluff will provide will also help support the higher levels of renewable energy we're integrating in the coming years."

Having flexible backup energy sources, including Castle Bluff, will not only help with energy reliability, especially in the winter, but will also create hundreds of construction jobs, several permanent jobs and additional tax revenue for the region.

Although such forward-looking statements have been made in good faith and are based on reasonable assumptions, there is no assurance that the expected results will be achieved. These statements include (without limitation) statements as to future expectations, beliefs, plans, projections, strategies, targets, estimates, objectives, events, conditions, and financial performance.

• regulatory, judicial, or legislative actions, and any changes in regulatory policies and ratemaking determinations, that may change regulatory recovery mechanisms, such as those that may result from Ameren Missouri's petition to the Missouri Public Service Commission ("MoPSC") for a financing order to authorize the issuance of securitized utility tariff bonds to finance the cost of the planned accelerated retirement of the Rush Island Energy Center, any additional mitigation relief related to the operation of the Rush Island Energy Center that may be ordered by the United States District Court for the Eastern District of Missouri, and Ameren Missouri's proposed customer energy-efficiency plan under the Missouri Energy Efficiency Investment Act filed with the MoPSC in January 2024;
• our ability to control costs and make substantial investments in our businesses, including our ability to recover costs and investments, and to earn our allowed returns on equity, within frameworks established by our regulators, while maintaining affordability of services for our customers;
• the effect on Ameren Missouri of any customer rate caps or limitations on increasing the electric service revenue requirement pursuant to Ameren Missouri's election to use the plant-in-service accounting regulatory mechanism;
• Ameren Missouri's ability to construct and/or acquire wind, solar, and other renewable energy generation facilities and battery storage, as well as natural gas-fired energy centers, extend the operating license for the Callaway Energy Center, retire fossil fuel-fired energy centers, and implement new or existing customer energy-efficiency programs, including any such construction, acquisition, retirement, or implementation in connection with its Smart Energy Plan, integrated resource plan, or emissions reduction goals, and to recover its cost of investment, a related return, and, in the case of customer energy-efficiency programs, any lost electric revenues in a timely manner, each of which is affected by the ability to obtain all necessary regulatory and project approvals, including certificates of convenience and necessity from the MoPSC or any other required approvals for the addition of renewable resources and natural gas-fired energy centers;
• Ameren Missouri's ability to use or transfer federal production and investment tax credits related to renewable energy projects; the cost of wind, solar, and other renewable generation and storage technologies; and our ability to obtain timely interconnection agreements with the Midcontinent Independent System Operator, Inc., a regional transmission organization, or other regional transmission organizations at an acceptable cost for each facility;
• the inability of our counterparties to meet their obligations with respect to contracts, credit agreements, and financial instruments, including as they relate to the construction and acquisition of electric and natural gas utility infrastructure and the ability of counterparties to complete projects, which is dependent upon the availability of necessary materials and equipment, including those obligations that are affected by supply chain disruptions;
• advancements in energy technologies, including carbon capture, utilization, and sequestration, hydrogen fuel for electric production and energy storage, next generation nuclear, and large-scale long-cycle battery energy storage, and the impact of federal and state energy and economic policies with respect to those technologies;
• the effects of changes in federal, state, or local laws and other governmental actions, including monetary, fiscal, foreign trade, and energy policies;

Given these uncertainties, undue reliance should not be placed on these forward-looking statements. Except to the extent required by the federal securities laws, we undertake no obligation to update or revise publicly any forward-looking statements to reflect new information or future events.
