Introduction

On June 5th, 2024, the Greater Memphis Area Chamber announced that xAI, Elon Musk’s artificial intelligence company, would establish the world’s largest supercomputer facility, “Gigafatory of Commute” at the former Electrolux site in Southwest Memphis. [1] This ambitious project centered on the “Colossus 100k H100 training cluster” is touted as the world’s most advanced AI training system powering the AI model nicknamed “Grok.” The opening of this facility promises over three hundred jobs and adds a six-billion-dollar investment for the region. [2] While the economic benefits of this venture are undeniably significant, they come with a familiar and concerning environmental cost. South Memphis is a predominantly black area and has long struggled with a range of challenges, from economic hardship to a history of poor health outcomes, likely exacerbated by nearby industrial pollution. South Memphians have long been targeted by harmful industrial activities, including a steel mill, a now-closed coal plant, a utility-operated gas power plant, and an oil refinery. [3]  As a result, the community has borne the brunt of environmental injustices, facing high asthma rates and a failing grade from the American Lung Association. The purpose of this paper is to examine the environmental concerns posed by the new xAI facility for the residents of South Memphis. To highlight these concerns, the following issues will be discussed: (1) air pollution risks and permitting failure, (2) water usage and potential threats to the aquifer, and (3) energy consumption and its impact on the power grid.

I. Air Pollution Risks

One of the most pressing concerns regarding the development and operation of the xAI facility is its failure to secure the necessary permits and its plan to operate 15 to 20 gas turbines continuously. 4 Gas turbines harm the environment by producing significant amounts of pollution each year, and adding 20 turbines will increase health risks for the already vulnerable residents of South Memphis. The Environmental Protection Agency (EPA) has recently acknowledged the issues of gas turbines and the need for stricter monitoring of nitrogen oxide levels, as this pollutant significantly contributes to smog, which contains ground-level ozone and particulate matter.5 Nitrogen oxide poses serious health risks to those who breathe it in, as Smog can irritate the respiratory system, leading to symptoms such as coughing, throat irritation, and shortness of breath.6 For individuals with pre-existing conditions like asthma, emphysema, or chronic bronchitis, smog can exacerbate symptoms, trigger attacks, and reduce lung function.7 On a community level, smog reduces visibility and creates a haze that detracts from the aesthetic of cities and affects daily life.8 On November 22, 2024, the EPA created measures to halt nitrogen oxide levels and proposed new regulations to strengthen limits on its emissions from most new, modified, and reconstructed fossil fuel-fired stationary combustion turbines.9 These proposed regulations aim to reduce air pollution from gas turbines for nearby communities and would help mitigate the impact of xAI's gas turbines by lowering the amount of nitrogen oxide going into the air. 10

It is no secret that residents of South Memphis have faced significant health challenges over the past four decades in large part due to numerous factories producing harmful pollutants. In 2017, Shelby County facilities reported that sites in Southwest Memphis accounted for 94% of the 6.6 million total tons of six "criteria" air pollutants identified in the most recent National Emissions Inventory compiled by the EPA.11 The American Lung Association has also highlighted the area’s severe air quality problems by issuing the area of South Memphis an “F” rating for ozone levels.12 The reporting provided by the EPA and the American Lung Association helps to explain why the total population of South Memphis has high amounts of asthma, COPD, and lung cancer.

This difficult situation has become increasingly concerning with the recent launch of a new facility operated by xAI as it is currently running gas turbines without the necessary permits from the Shelby County Health Department.13 The xAI facility has already deployed nearly 20 gas turbines, including four large units with a combined capacity of 100MW, to power its AI system Grok.14 There are plans to add 15 more gas turbines between June 2025 and June 2030, and the turbine application projects annual emissions of around 11.51 tons of hazardous air pollutants. 15 Over 5 years, this would amount to roughly 57.55 tons of hazardous pollutants which adds to an already extremely high level of ozone and particulate matter for the area. As a result of not obtaining permits from the Shelby County Health Department the lack of compliance by xAI is likely exacerbating air quality issues for the residents in South Memphis and causing them more symptoms and respiratory harm. According to Amanda Garcia, an attorney with the Southern Environmental Law Center, “Every day that the turbines are operating, they are polluting the air and doing significant harm to families in South Memphis.”16

To make matters even worse, there is a history of Elon Musk's companies, such as SpaceX and the Boring Company, being fined thousands of dollars for violating environmental law to circumvent regulation.17 This secretive behavior by xAI and by the City of Memphis has caused community apprehension of the tech company, leaving residents of South Memphis with more questions than answers. One of the reasons that xAI likely purchased this site in South Memphis is because it was zoned as “heavy industrial” which allows for many industrial activities without the need for permitting.18 This, however, does not provide xAI with the greenlight to do as they wish as this attempt at regulatory circumvention is of extreme significance for the area, as a large portion of the population suffers from asthma and other health problems. As a result of failing to get the necessary permits, symptoms of asthma and other health conditions are likely to steadily increase. This is truly unfortunate for residents of South Memphis as the community's concerns seem to be going unanswered and the hope that elected officials are prioritizing the well-being of the area is rapidly diminishing.

 The xAI facility, however, can address this issue by acquiring the proper permits from the county, by adhering to the newly proposed New Source Performance Standards (NSPS), and simply by being transparent with the local community. The new NSPS focus on implementing combustion controls and selective catalytic reduction (SCR), which are cost-effective and widely used technologies designed to limit emissions of nitrogen oxides (NOx).19 NSPS are authorized under Section 211 of the Clean Air Act and have historically succeeded in reducing pollutants from new industrial sources. All new sources must comply with the Best System of Emission Reduction (BSER), which mandates the use of state-of-the-art technology to minimize air pollutants.20 If xAI follows the law and obtains the necessary permits, the facility will be cleaner and safer for the residents of South Memphis. Even if xAI contends that they are not required to follow this procedure, findings from the Southern Environmental Law Center indicate that the facility has "installed" gas turbines.21 This suggests that new industrial systems are in place and that xAI is obligated to comply with the new NSPS to avoid violating the Clean Air Act. To operate gas turbines in the area, xAI must apply for the appropriate permits and adhere to legal requirements, as environmental tests and studies demonstrate that NSPS effectively limit environmental pollutants.

II. Water Usage and Threats to the Aquifer

If you’ve ever visited Memphis, you’ve likely heard that its tap water is some of the best in the United States. This reputation stems from the city's access to the Memphis Sand Aquifer, one of the oldest and largest clay-based aquifers in the country. With an estimated 57 trillion gallons of ancient, pristine water, this aquifer holds a water reserve that many cities can only dream of having at their disposal.22 The xAI facility requires unprecedented access to the Memphis Sand Aquifer, as its AI systems need vast amounts of water for cooling purposes. It’s estimated that the facility could demand up to 1.5 million gallons of water per day. 23 While the 1.5 million gallons would not inherently be an issue, Daniel Larson, the director of the University of Memphis’ Center for Applied Earth Science and Engineering Research or (CAESER) has concerns that the xAI system’s demand for water could accelerate contamination of the Memphis sand aquifer.24 The Memphis aquifer is typically shielded from contaminants by a clay layer, but there are 16 known breaches and 36 suspected breaches in Shelby County that allow the shallow, often contaminated groundwater to mix with the deeper Memphis Sand.25

The challenge for residents of South Memphis is that the xAI facility is situated near the Davis Wellfield, which sits directly above shallow groundwater contaminated with arsenic.26 This contamination dates to the Tennessee Valley Authority’s (TVA) coal ash ponds, which have been leaking hazardous materials into the ground for decades.27 The coal ash was a byproduct of burning coal for electricity and contains harmful substances like arsenic, lead, and mercury.28 As the xAI facility requires massive amounts of water, the potential for further disruption to the groundwater system increases, furthering fears that the xAI facility's extensive water usage could exacerbate contamination in an already vulnerable area, threatening both the environment and public health.29 If the xAI facility engages in excessive water pumping, which it likely will, then this facility could accelerate the downward migration of contaminants through the known 16 breaches and further pollute the Memphis Sand Aquifer.30

This situation could be mitigated if xAI, the TVA, and other industrial facilities in the area collaborate to establish a shared water reuse facility at the local wastewater plant. Such a solution would allow for the safe recycling of water, reducing the strain on the Memphis Sand Aquifer and minimizing the risk of further contaminating the groundwater. Protect Our Aquifer supports this resolution, emphasizing that proactive cooperation to address the issue now, before it escalates into a crisis, would be a win for the residents of South Memphis and the long-term health of the aquifer.31 The xAI facility does recognize the need for aquifer management and has plans to reduce aquifer strain by constructing an 80-million-dollar greywater facility called “Colossus Water Recycle Plant” which hopes to reduce strain on the aquifer by 9%.32

Many residents in South Memphis also have concerns about xAI managing the greywater facility, particularly because of the company’s history of avoiding necessary regulations. For instance, xAI bypassed the required permits for its gas turbines, which has led to distrust among the community.33 Additionally, while the greywater facility shows promise, it is still waiting on the necessary permits and funding. Delays in obtaining these permits could lead to a prolonged dependency on the aquifer, potentially worsening risks tied to over-extraction. While waiting for the facility’s construction, South Memphis residents must depend on Memphis Light, Gas & Water’s existing wells to meet water demand until the greywater facility is ready in 2026-2027.34

Another main concern is the high-power demand from the Tennessee Valley Authority, which places additional stress on an already fragile electricity grid and water system. This vulnerability was highlighted by the 2022 blackouts and boil water advisories.35 Without enforced mitigation measures should the greywater facility fail, xAI’s operations could worsen existing vulnerabilities in the region.36 The aquifer’s recharge rate is not easily determined and over-extraction in the West Tennessee recharge zone may lead to depletion rates that outpace the aquifer’s natural replenishment.37 The fear is that xAI will use too much water, the aquifer will not replenish fast enough, and contaminants will permanently alter the aquifer’s pristine condition.38 The xAI facility needs to pay close attention to what its dumping into the water supply and strive towards getting the Colossus Water Recycle Plant operational as soon as possible.

IV. Energy Consumption and its Effects on the Power Grid

Artificial Intelligence is the undeniable future of our world, and we have no choice but to embrace it. To support and sustain this new era, we need a powerful and efficient grid that can meet the demands of an AI-driven world. As xAI expands its operations in Memphis, the demand on the local power grid will undoubtedly increase. The Grok AI model will require vast amounts of computing power, which in turn necessitates significant energy consumption.39 This will put major pressure on Memphis Light, Gas, and Water (MLGW), the utility company responsible for providing electricity to the area, to ensure the grid can meet these new energy demands.40

The xAI facility will require large amounts of power, with the initial phase requiring 150 MW of power, approved by the Tennessee Valley Authority Board.41 Dough McGowen, current CEO of MLGW, states that the 150 MW of power equates to the power needs of approximately 100,000 homes.42 Both the TVA and MLGW have confirmed that this energy output is sustainable for the power grid, but many residents have grown concerned as xAI’s original demand of 150 MW has been doubled to 300 MW at the beginning of this year.43 This new doubled demand also required the building of a second substation as well as additional transmission upgrades with projections suggesting a potential 1,500 MW load if expansion continues.44 As the xAI facility continues to progress in development, MLGW facilities and infrastructure will be extremely tested as the peak energy demand is around 4,500 MW of power across the Shelby County area.44 The TVA’s regional capacity has also shown that its peak strain was around 33,427 MW during the 2022 winter storm month.45 MLGW has responded to the power increases this year by upgrading nearby substations from 8 MW to 50 MW at a cost of around $750,000, and xAI has invested 24 million for the remainder of the 150 MW substation and its construction. 46

Environmental advocates take a differing approach with organizations such as the Southern Environmental Law Center (SELC) arguing that prioritizing industrial users like xAI during peak demand could leave residential customers vulnerable, especially during extreme weather.47 SELC states that this approach goes against TVA’s mission to focus on the public's welfare and that the 2022 weather situation showed that adding hundreds of megawatts without new generation capacity could lead to system failures, especially since xAI’s temporary turbines, are being supplied 35-50 MW of power until permanent connections are made.48 The Southern Alliance for Clean Energy also highlights similar concerns by explaining that the math is “simple and alarming” as xAI proposed 100,000 CPUs which use 150 MW of power each totaling 1,000-1,500 MW of power which is a very large portion of the peak demand of the City of Memphis, further utilizing an already stressed system as Memphis has the highest energy burden of any metro in the United States.49 SACE estimates that scaling from 150 MW of power to 1500 MW of power is equivalent to powering 1 million homes and could require a 1-1.5 GW power plant, which could cost around 1.5-2 billion dollars.50 MLGW and TVA need to proceed with caution in planning this expansion, as the Southern Alliance for Clean Energy warns that if things go wrong, Tennessee could become reliant on fossil fuels through 2050.51 This would undermine the TVA’s goal of reducing greenhouse gas emissions of 70% by 2035.52

Memphis leaders have also voiced concern over the energy situation with councilwoman Yolanda Cooper-Sutton stating, “We can’t get good electricity on a good day.”53 Many residents, particularly those located in South Memphis resonate with this statement as frequent power outages are an all too familiar occurrence. The continual expansion of xAI and its goal of reaching 1,500 MW by 2030 would unequivocally alter the TVA and MLGW power grid over the next several decades.54 This 1,500 MW demand is roughly a third of Memphis’s current peak of 4,500 MW and risks weighing taxpayers with billions in costs for the construction of new fossil fuel plants if TVA and MLGW fail to adapt to these significant power changes.55 The power grid will likely require significant upgrades to meet the growing demands of xAI and its operations. MLGW and TVA should prioritize the needs of Memphis and Tennessee residents over the requirements of the xAI facility to ensure reliable and effective service for the community.

Conclusion

Residents of South Memphis deserve clean air, clean water, and reliable electricity. The xAI facility has incredible potential to push forward the development of artificial intelligence and the City of Memphis stands to gain significantly from the advancements in this field. However, this potential cannot come at the expense of the community’s well-being. One of the largest concerns with xAI’s development is the company's lack of transparency. The people of Memphis, particularly those in South Memphis, have not been fully informed about the potential environmental and health impacts of the facility. There is a growing concern noted by environmental groups that the facility could increase pollution or strain local resources, but the conversation around this has been minimal. xAI needs to communicate openly with the community about how the facility is operating and how it will impact the environment. If xAI commits to protecting South Memphians and the environment, then the facility has an opportunity to set new standards of how large-scale industrializers operate. Memphis needs to make sure xAI is held accountable and that they are following EPA guidelines and obtaining required permits and xAI needs to do a better job of listening to the concerns of experts who warn about potential environmental damage.

If xAI can develop a meaningful partnership with MLGW, TVA, and the residents of South Memphis, the city can become the center of one of the most groundbreaking technological advances of our time. This collaboration would allow Memphis to grow both economically and technologically, while ensuring that its residents’ needs and concerns are met. Memphis can truly become a global leader in artificial intelligence, but it needs to do so in a way that respects the people who live here and the environment they depend on. If everyone involved works together, we can make sure that Memphis thrives as a city of innovation and sustainability, benefiting both the people who live here today and the generations to come.
