I am an Ameren Missouri customer who will be directly impacted by this proposal. Every rate increase, service disruption, and corporate expansion decision Ameren makes affects all of us across the state. We’re already paying higher bills while facing unreliable service and frequent shutoffs. It’s deeply concerning that Ameren continues pursuing costly industrial projects instead of focusing on affordability, accountability, and fair treatment for the families who depend on them. I urge the Missouri Public Service Commission to listen to the voices of customers who are tired of footing the bill for corporate deals and infrastructure that primarily benefit large data centers and high-volume clients. We need investment in people *See attached

I am concerned about the gas plant being proposed to serve "large load customers" i.e. data centers, which have already received public backlash and resistance towards. Gas plants produce large amounts of methane, which are one of the greatest contributors to global climate change as well as many of the issues we have seen in Missouri. Many health issues can be attributed to these emissions, as well as the runoff that pollutes the river and ends up downstream into Missouri soil. It is time to start thinking about how we want to progress as a city. This means thinking long term and fossil fuels are a dated, unethical, unreliable, costly, and dangerous product that we should not be investing any more money into. We have to think of the future

Case # EA-2025-0238 The battery storage makes sense. The proposal for a natural gas thermal plant is sorely lacking in a number of ways. Ameren says nothing about the social costs of the greenhouse gas emissions from a natural gas plant; neither the CO2 from combustion, nor the methane leakage from the wells to the power plant. A tipping point for coral reefs has already been crossed, and other tipping points will be crossed as we go above 1.5 C of average global warming. The Ameren proposal lacks an alternative of solar panels for new generating capacity. Decentralizing the generation and storage of electricity would make the system more resilient to the impacts from increasing extreme weather events.

I do not support the building of a methane gas plant at Rush Island. SB4 is not written out to protect consumers from rate increases and I do not support the negative environmental impact a methane gas plant would have in the pursuit of powering "large load consumers" (ie: data centers). As a consumer I cannot believe this plan is moving forward with the overwhelming lack of support from Missouri constituents.

Solar and wind energy are cheaper than ever. Combined with battery storage, solar and wind could provide cheap, reliable, and safe alternatives to methane. Methane gas is also more expensive than solar or wind, so this new plant is likely to increase utility prices for all Ameren customers. This is the type of plant that failed in Texas in 2021, killing hundreds. Missourians have already shown their opposition to new data centers like the one in Midtown St. Louis. Building a costly new plant to serve a data center that will only increase pollution and health risks is likely to be hugely unpopular.

I am writing about the proposed Rush Island Gas Plant expected to serve large load customers like data centers. If Ameren must service data centers, they need to use cheaper and cleaner renewable energy sources, like wind and solar and battery storage. Natural gas or methane emissions trap over 82.times more heat than carbon dioxide emissions, increasing global warming and also pollution. The cost, the risks to health and environment are vital reasons to shift the plan to renewable energy sources. Thank you for your consideration. I will be following this matter.

"I would urge the PSC to reject any proposal to build an AI data center. They suck water out of the ground, decimate the land of the local communities and are only beneficials to the electric companies.

Ameren says the center is necessary for reliability, affordability, and sustainability. In reality, it supports none of these goals. Failure of gas infrastructure killed hundreds in Winter Storm Uri. Gas takes longer to build and is more expensive to operate than wind or solar. Finally, methane gas is a harmful fossil fuel, which when extracted, transported, and burned releases pollutants like VOCs and NOx, leading to childhood cancers, birth defects, and respiratory issues. On behalf of Missouri's people and our environment, I respectfully urge a "no" vote on the Big Hollow methane gas plant. Please see attached for fuller details and research sources.

Please do not approve the Rush Island proposal to build a gas plant to provide fuel for data centers. Methane gas is extremely bad for the environment, unreliable, and expensive. Methane emissions trap over 82.5 times more heat than carbon dioxide emissions. We are already dealing with the costs and impacts of too much carbon dioxide in MO. Data center demand should not impact Missourians' health. It is expensive, dangerous (killed people in Texas) and increases our reliance on imports. Methane gas is a limited resource. Solar and wind are not limited and can be produced in Missouri, while gas has to imported to the state. Ameren can and should do better. Renewable energy is both cheaper and more reliable than ever.

I strongly urge the PSC to reject the application as submitted. I do not support the negative environmental impact a methane gas plant would have in the pursuit of powering large load consumers. Gas plants produce large amounts of methane, which are one of the greatest contributors to global climate change. In addition, methane gas when extracted, transported, and burned releases pollutants like VOCs and NOx, leading to childhood cancers, birth defects, and respiratory issues. Ameren says nothing about the social costs of the greenhouse gas emissions from their proposed natural gas plant. Ameren needs to use cheaper and cleaner renewable energy sources. As a native Missourian, I strongly urge a "no" vote.

I am concerned about Ameren's proposal to build a gas plan on Rush Island to future support data centers requirements. Methane gas contained in natural gas is even more damaging than coal as its traps over 80% more heat than carbon dioxide emissions. A better strategy would be to make a comparable investment in solar and wind energy which would be healthier for residents of Missouri. It is cheaper and more reliable than ever and will continue to improve in the coming years. Using methane gas escaping from landfills is understandable, but not this plan. Please do not move forward with this plan.

Please do not approve the proposal for Rush Island Ameren Methane Plant, which plant is proposed explicitly to serve "large Load customers", and which would come with huge and lasting costs for all of us. Methane is expensive and unreliable, and its use gravely impacts our environment. Our region is already facing the increasing effects of an overheated planet. It is irresponsible to put on blinders and proceed with this type of fossil fuel development. Ameren has the option of considering clean, renewable, and affordable energy sources, sources which can serve data centers, without the heavy financial burden and severe health risks tied to the pending proposal.

If Ameren wants to serve data centers, they must do so with clean, cheap, reliable renewable energy, not asthma-inducing, planet warming, expensive methane gas. The energy costs of these data centes are not worth what they are providiing Missourians.

Ameren is seeking to expand its generation capacity in a way that counters Missouri energy independence by making us more dependent on imported fuels; will undermine long-term energy security and economic well-being through use of expensive natural gas; and will undermine clean energy initiatives while adding to air pollution and potent greenhouse gases which power catastrophic storms and wild temperature swings and are only getting worse. Missourians cannot foot the bill for dirty energy expansions that promise nothing but higher costs. Future generations do not deserve to be burdened with the economic and ecological debt this gas plant will create. Reject Ameren’s proposal and tell them to do better. We deserve it.

I urge the Commission to defer approval of Big Hollow until the Large-Load Customer Tariff is finalized and its cost-allocation safeguards are public; or condition approval to state explicitly that the plant may operate only as a reliability and grid-stabilization asset, not as pre-emptive infrastructure for unapproved private load commitments. Reliability investments must serve the public, not backfill contractual obligations to undisclosed hyperscale customers. Approving the Big Creek Hollow facility today before the tariff and the Big Creek facility today before the tariff and its cost-allocation safeguards are finalized would amount to pre-approval of those private interconnection agreements and the infrastructure built to serve them.

I ask the Commission to oppose the proposed Natural Gas Power Plant at Rush Island. Instead I suggest the Commission encourage Ameren to pursue cleaner energy production. Methane gas prices are extremely volatile; they change wildly depending on global politics. Methane gas is more expensive than solar or wind. This is the type of plant that failed in Texas in 2021, killing hundreds. There are better options for Missouri residents & the economy. Renewable energy, especially solar and wind, is cheaper than ever before, especially when combined with battery storage. Methane gas is a limited resource. Solar and wind are not limited and can be produced in Missouri, while gas has to imported to the state. Please protect consumers!

To Mo Public Service Commission: It is my pleasure to offer this letter of support in favor of Ameren new power generation project in Jefferson County known as BIg Hollow. For several years I have been concerned on what Ameren will do to replace the energy supply for our region once Rush Island had been shuttred. I am please with the forearm thinking and planning to bring back the energy manufacturing to our County. I whole heartedly support the proposeal project in our County. Respectfully submitted, Dennis J. Gannon County Executive, Jefferson County, Missouri

Ameren wrongfully removed me from the keeping current plan. I didn't know that a former friend who helped me canceled payment so I didnt know why I got a letter saying I was in danger of being removed from the program. I contacted ameren ensure I was still on the program and tell them how important it was for me to continue on the program and make sure everything was ok with it. They assured me everything was ok and then less than 10 days later they removed me from the program. The bills they send don't reflect the true amount due they reflect the actual bill, so it's very confusing and hard to understand. If they would of told me I would of paid it and things would of been fine but they set me up and now won't let me back on the program.

I do not support the addition of any new fossil-based resources to Ameren Missouri's (AMO) generation portfolio. This is going in the wrong direction for AMO's promised Clean Energy Transition commitments. In addition, it puts rate pressure on vulnerable customers especially without the promised SB4 customer protections in place. Rather than adding even more carbon-based resources, I urge AMO to explore additional BESS options, EE programs, renewable resources, pro-DER policies, nuclear energy expansion / license extension, and virtually any other option than planet-warming carbon resources to make load growth possible. Otherwise, it appears coal plant retirements are only a pretext to justify new capex to benefit AMO.

I urge the commission to reject the proposal for a simple-cycle natural gas plant at Rush Island. It boggles the mind that Ameren would continue to build fossil-fuel plants when the company has a stated goal of reaching net zero by 2045. Battery storage should be used to increase the reliability of cheap renewable power from solar and wind. Natural gas is a potent greenhouse gas when it leaks from pipelines, and less than half of the energy created when natural gas is burned is captured for power generation, meaning half of the gas burned will end up polluting our air and our atmosphere while generating zero benefit. Build renewables, get free power from nature, lower rates and stop enriching investors at the expense of the public!
