Data Center Signal is tracking 21 clips about Ameren data center developments across 2 states, including MO, IL.
Missouri’s new state energy plan calls for expanded nuclear power, transmission capacity and redevelopment of former industrial and power-generation sites as electricity demand rises. State officials cite expected growth from artificial intelligence data centers, while two data center projects in Montgomery County have generated community concerns.
A federal study says Missouri and other states will need major transmission upgrades as electricity demand rises, driven partly by the expansion of AI data centers. Missouri officials and consumer advocates are concerned that infrastructure costs could be passed on to residential utility customers, while federal officials say data center operators should pay their share.
Ameren is proposing an 11,000 MW energy plan over two decades, primarily with natural gas, to meet increasing demand from data centers in Missouri. The plan faces criticism from the Sierra Club due to environmental concerns about increased fossil fuel use.
Clean Cloud Energy is in preliminary talks with the Village of Mahomet, Illinois, for a potential data center project, the "Rising Edge Data Center." Developers claim the project will use zero water for cooling and not impact local energy, but environmental groups and the public remain concerned. Champaign County currently has a moratorium on data center development, and a task force is drafting new zoning regulations.
Ameren Missouri officials discussed the critical requirement for a power-use study for CRG's proposed $6 billion hyperscale data center in Festus. This study, which can take several months, is essential to determine electrical capacity and can be a deciding factor for the project's progression. Ameren also clarified that any necessary infrastructure upgrades would be fully funded by the customer.
Illinois officials, lobbyists, and industry groups are debating new statewide regulations for data centers amidst growing backlash. Proposals include requirements for closed-loop cooling, data centers to bring their own power, and changes to biometric privacy laws and tax incentives. A task force is meeting to address these issues before the fall legislative session.
St. Louis aldermen clashed over amendments to proposed data center zoning rules, which some sponsors believe weaken the original intent, particularly regarding renewable energy requirements. The approved amendments to Board Bill 49 mean it will return to the city's Planning Commission before a final vote. Alderwomen Anne Schweitzer and Alisha Sonnier expressed concern that the changes prioritize economic growth over well-being and environmental goals.
Ameren Missouri has requested a mid-2027 rate increase of $343 million, which would raise the average customer's electricity bill by $13, citing investments in infrastructure and growing demand from "large-load customers" like data centers. Consumer protection groups are scrutinizing the proposal, arguing that data centers should bear more of the costs for new generation needed to meet their significant energy demands. The Missouri Public Service Commission will review the request over the next 11 months.
Google and Amazon are investing billions in new data centers in New Florence, Missouri, with commitments to cover grid connection costs and fund community services. These developments occur under consumer protection laws, like Missouri's Senate Bill 4, which aim to prevent utilities from passing data center-related costs onto consumers. The article highlights the broader national trend of increasing electricity consumption by data centers and the financial implications for utilities and customers.
The Warrenton Planning and Zoning Commission approved the preliminary and final plat for the Warrenton Data Center on June 4. This follows prior approvals from the Board of Aldermen, which included specific conditions related to landscaping, lighting, noise levels, and generator placement. Ameren is involved in designing and constructing an electrical switchyard for the site.
Ameren Missouri is seeking Public Service Commission approval to add 400 MW of solar generation and 545 MW of energy storage across several Missouri counties. This expansion is partly driven by the anticipated electricity demands of new data centers from companies like Google and Amazon in the state. The Missouri Office of Public Counsel has expressed concerns that the solar facilities primarily benefit large-load customers.
The surge in AI demand is increasing data center construction costs and power consumption. In response, Constellation is investing $800 million to upgrade its Braidwood and Byron nuclear plants in Illinois, adding 158 megawatts to the grid by 2029. This initiative is part of a broader discussion among utilities and environmental groups on how best to meet the state's growing energy needs.
ComEd rates in Illinois are set to increase this summer, largely driven by rising demand for electricity, particularly from data centers supporting the artificial intelligence industry. The rate hike also stems from increased prices set by power-generating companies at a recent PJM Interconnection auction and the discontinuation of a temporary customer credit.
Constellation is investing $800 million to upgrade its nuclear power plants in Illinois, specifically Braidwood and Byron, to meet rising electricity demand driven by data centers. This initiative aligns with recent state government actions, including lifting a moratorium on new nuclear plant construction and executive orders to accelerate nuclear generation. Other utilities and environmental groups weigh in on the state's energy strategy, emphasizing grid reliability and the role of both nuclear and renewable sources.
Logan County's zoning committee has recommended a new 90-day moratorium on data center construction with a 3-2 vote. This decision followed extensive debate involving potential developer Hut 8, with warnings that a moratorium could jeopardize the project due to an expiring agreement with Ameren. The Logan County Board is now set to make a final decision on the proposed moratorium.
The Village of Dix, Illinois, unanimously approved a 180-day moratorium on new data centers, solar farms, and warehouses to establish new zoning and land-use regulations. This decision followed strong public concern over potential data center development in Jefferson County, driven by rumors and an interconnection application submitted to Ameren by a developer affiliated with RWE. Residents voiced opposition regarding high energy and water usage, noise, and pollution.
The Trump administration reversed federal soot standards, previously set to improve air quality in cities like St. Louis, to prioritize electricity demand from data centers and the AI boom. This decision ensures coal plants, like Ameren's Labadie Energy Center, can continue operating without costly upgrades, leading to renewed concerns from environmental activists about increased pollution and health risks. Data center growth is projected to create significant new electricity demand, which utilities like Ameren are preparing to meet, including for large projects like an Amazon Web Services facility in Montgomery County.
The AI boom and increasing data center electricity demand are reversing clean air gains in St. Louis, Missouri, due to reliance on coal-fired power plants like Ameren's Labadie Energy Center. Activists are concerned about increased pollution and health risks, especially after the Trump administration rescinded federal emissions standards.
The AI boom's electricity demand has led to the Trump administration rolling back clean air standards, impacting cities like St. Louis, Missouri. This decision has derailed decades-long efforts by activists to reduce coal pollution, notably from Ameren's Labadie Energy Center. Environmental groups and residents are expressing concern over the health implications and increased pollution.
AI-driven data center demand is prompting the rollback of clean-air regulations, leading to fears of worsening pollution in cities like St. Louis. This policy reversal keeps coal plants, such as Ameren's Labadie Energy Center, operating despite previously planned emission reductions. Activists are concerned about the health impacts on already polluted communities.
