xAI Colossus, Boxtown

What the ground held

Map: Boxtown and Westwood before the Colossus campus

Boxtown began in the years after 1863 as a community of emancipated freedmen on the southern edge of Shelby County, outside the boundaries of what was then the City of Memphis.¹ The name came from the houses the first residents built from discarded railroad boxcars; the surviving records name no single founder, because the community formed the way many freedmen’s settlements formed, as a gathering of people who had secured enough land and enough kin to support the building.² The surviving nineteenth-century records name the Rogers and White families. White’s Chapel African Methodist Episcopal Church, built in 1890 and still standing on Weaver Road, took its name from the latter.¹

The commercial life that grew up around the church followed the pattern that every Black settlement in the Jim Crow South followed. Families ran grocery stores, funeral homes, barbershops, and dry-goods stores because Memphis closed its white commercial districts to them, formally or informally. S.L. Jones opened a grocery at the intersection of Sewanee and Fields Roads in the 1930s and eventually expanded it into the Jones Big Star Markets chain on McLemore Avenue.¹ The neighborhood did not produce a commercial corridor on the scale of Beale Street, which sat ten miles north in the heart of Black Memphis, but it produced the institutions every freedmen’s settlement produced to sustain itself across a century of enforced self-reliance.

Memphis tried to annex Boxtown in 1968 and failed. The city succeeded on December 31, 1971, pulling roughly 21 square miles of South Memphis, including Boxtown, into the municipal boundary.¹ The annexation gave the city tax authority over the area and pulled its residents into city elections; the annexation did not, in the decades that followed, deliver the water and sewer connections, the paved streets, or the zoning protection that the city was simultaneously delivering to East Memphis and Cordova.³

What the zoning did not restrict settled in instead. The Valero Memphis refinery, originally built in 1941 and expanded repeatedly through the 1960s, sits a mile east of Boxtown on the Riverport industrial corridor. The Allen Fossil Plant, the Tennessee Valley Authority coal-fired power station that operated from 1959 until 2018, left its coal-ash ponds on the Mississippi River bluff immediately west of the neighborhood.⁴ The T.E. Maxson Wastewater Treatment Facility, which processes most of South Memphis sewage, sits a mile to the north. In the middle of the industrial ring, the 800-acre former Electrolux Home Products assembly plant complex, built with $20 million in state and local tax incentives in 2013 and closed in 2020 after only seven years of operation, sat empty through the early 2020s.⁵

The census tract that contains Boxtown, according to the 2020 decennial and the 2022 American Community Survey five-year averages that MLK50 published in 2021, reports a population that is 99 percent Black with nearly half of households reporting incomes under $25,000.³ The neighborhood sits inside the Memphis Sand Aquifer’s most sensitive recharge zone; the aquifer supplies all of Shelby County’s drinking water and is vulnerable to drawdown and contamination from the industrial uses layered above it.⁶

What xAI took

Map: The 550-acre xAI campus on the former Electrolux site

xAI incorporated in Nevada in March 2023. Elon Musk, the company’s founder and largest shareholder, announced in June 2024 that xAI had acquired the former Electrolux Home Products site at 3231 Paul R. Lowry Road in Boxtown for the company’s first training supercomputer, which he called Colossus.⁷ The announced plan called for 100,000 Nvidia H100 GPUs in the first training cluster, a figure the company expanded to roughly 200,000 by the end of 2024, and for up to 2,000 megawatts of eventual power draw across the campus.⁸ The company declined to publish a water or energy budget at announcement.

The Tennessee Valley Authority, which serves Memphis through Memphis Light, Gas and Water as the local distribution utility, had not committed to the 2,000-megawatt figure and could not have delivered it without substantial new transmission investment. To bridge the gap, xAI installed 35 natural-gas turbines on the Electrolux site in the second half of 2024 to generate onsite power for the first training cluster.⁷ The company did not apply for a Clean Air Act Title V major-source permit before installing the turbines. Company counsel took the position that a 364-day “operational waiver” available under Tennessee air-permit regulations covered the installation and operation of the turbines while the company pursued a permanent permit.⁵

Legal experts who reviewed the position, including attorneys at the Southern Environmental Law Center, have disputed the theory. Clean Air Act Section 165 requires a preconstruction permit for any new major source of regulated air pollutants, and thirty-five gas turbines collectively producing over 2,000 tons of nitrogen oxides annually plainly qualify as a major source.⁷ The Shelby County Health Department, which the Environmental Protection Agency has delegated air-permit authority over the Memphis area, took the company’s position at face value and did not halt operation during the informal review period that stretched from late 2024 into the first half of 2025.

The county health department approved the air permit on July 2, 2025, after more than a year of public protest and public-comment hearings that Memphis Community Against Pollution, Young, Gifted and Green, and the NAACP Memphis branch had organized.⁷ The department issued a Code Orange air-quality alert for the Memphis metropolitan area on July 3, 2025, the day after it approved the permit.⁷ Sharon Wilson, a Texas-based air-quality investigator with Earthworks, published optical gas imaging data from the site that same summer documenting what she called “horrific amounts of pollution” leaving the turbines, including methane, nitrogen oxides, and formaldehyde.⁷

The Southern Environmental Law Center filed an administrative appeal of the July 2025 permit within the month, representing the NAACP Memphis branch, Memphis Community Against Pollution, and Young, Gifted and Green as co-appellants.⁵ The appeal is pending. MLK50 reporter Carrington Tatum, working the beat from the newsroom that Wendi C. Thomas founded in 2019, documented the flawed air-quality test that preceded the permit in a July 3, 2025 article; the test had relied on modeling assumptions the department had not validated against on-site measurement.⁹

By mid-2025 the campus drew roughly one million gallons per day from the Memphis Light, Gas and Water municipal system, which pulls entirely from the Memphis Sand Aquifer.¹⁰ MLGW did not meter the figure separately for xAI until 2025, and the number remained in dispute across several months of public-records requests.¹¹ The company subsequently broke ground on an $80 million Colossus Water Recycling Plant to pull treated effluent from the T.E. Maxson Wastewater Treatment Facility, a project Musk placed on hold in late 2025 until Colossus 2 completion.¹²

What the ratepayers paid and the aquifer lost

Map: MLGW grid, TVA transmission, and Memphis Sand Aquifer

The 150 megawatts of onsite generation the Shelby County Health Department has approved, running at the continuous duty cycle a training supercomputer requires, produces on the order of 1.3 million megawatt-hours of electricity each year. The United States Energy Information Administration reports that the average residential utility customer in the Southeast consumes roughly 14,800 kilowatt-hours annually, a figure that places Tennessee residential consumption somewhat above the 10,791 kilowatt-hour national average because of the region’s dependence on electric heating and summer cooling.¹³ On that ratio, Colossus in its currently approved configuration produces as much electricity as approximately 89,000 Tennessee households consume in a year.

The announced full-build figure of 2,000 megawatts, if ever delivered through a combination of onsite generation and TVA grid expansion, would carry an annual consumption on the order of 17.5 million megawatt-hours, equivalent to roughly 1.2 million Tennessee households. Memphis Light, Gas and Water serves approximately 431,000 electric customers across Shelby County, a customer count the utility publishes on its about page.¹⁴ In the 2,000-megawatt scenario, a single customer facility would consume approximately three times the electricity of the entire MLGW residential base. The transmission, generation, and ratepayer-cost implications of that scenario have not been disclosed in any public MLGW or TVA proceeding as of April 2026.

Water consumption at the approved one-million-gallon-per-day figure translates to approximately 365 million gallons per year. Tennessee residential customers consume roughly 90 gallons per day per person, or approximately 32,850 gallons per year, according to standard United States Geological Survey estimates.⁶ The Colossus campus at current operation consumes as much water as approximately 11,100 Tennessee households. If the 13-million-gallon-per-day figure xAI has described as its long-term cooling need materializes, the campus would consume on the order of 4.7 billion gallons per year, roughly 145,000 household-equivalents.¹⁰

Protect Our Aquifer, the Memphis-based nonprofit that emerged from the Byhalia Connection pipeline fight alongside Memphis Community Against Pollution, has published aquifer-drawdown modeling that describes how sustained industrial pumping at these magnitudes accelerates the Memphis Sand Aquifer’s vulnerability to contamination from the Mississippi River floodplain and from the coal-ash ponds the Allen Fossil Plant left behind.¹¹ The modeling has not been formally contested by the utility or by the state environmental agency.

The Tennessee Department of Environment and Conservation has not required cumulative-impact analysis of the xAI campus, the Valero refinery, the Allen Fossil ash ponds, and the Maxson wastewater facility as a single exposure profile for Boxtown residents. The Shelby County Health Department has not required it either. Memphis Community Against Pollution, Young, Gifted and Green, and the Southern Environmental Law Center have requested cumulative-impact analysis in every filing. The requests remain pending.⁵

Who fought back

Map: Boxtown's organizing and civic infrastructure

The organizing tradition that confronted xAI in 2024 and 2025 began, in its current institutional form, in 2020. That year Plains All American Pipeline and Valero Energy announced the Byhalia Connection, a forty-nine-mile crude-oil pipeline that would cross the Memphis Sand Aquifer on a route through Boxtown, Westwood, and the surrounding freedmen’s settlements on its way to the Valero refinery.¹⁵ A Plains executive, captured on a recording the Memphis Flyer later obtained, called the route “the path of least resistance.”¹⁵

Resistance gathered quickly. KeShaun Pearson, a Memphis educator and Boxtown resident, founded Memphis Community Against the Pipeline in October 2020. The organization paired door-to-door canvassing with city-council testimony, with aquifer-science briefings that Protect Our Aquifer’s Sarah Houston and Ward Archer led, and with legal support from the Southern Environmental Law Center. The Sierra Club Tennessee Chapter joined as a coalition partner. The Memphis City Council passed an ordinance restricting pipeline routing over the aquifer in late 2020; the Shelby County Commission followed. Plains All American and Valero canceled the Byhalia Connection on July 2, 2021.¹⁵

Memphis Community Against the Pipeline rebranded as Memphis Community Against Pollution in 2022 and carried the same coalition structure into subsequent fights. When xAI acquired the Electrolux site in June 2024, MCAP was the first organization present in Boxtown. Pearson, now president of the renamed organization, gave the first neighborhood press conferences, organized the first community hearings, and recruited the Boxtown residents whose testimony anchored the Shelby County Health Department’s public-comment record across 2024 and 2025.¹⁶

Young, Gifted and Green, the youth-led environmental-justice organization that LaTricea Adams had founded in 2016 as Black Millennials for Flint, joined as co-organizer in 2024. Adams had grown up in the Hyde Park and South Memphis neighborhoods adjacent to the industrial corridor. The organization paired multi-city fellowship programs with on-the-ground Memphis organizing and brought a youth voice into the permit hearings that the health department had previously treated as an older homeowners’ concern.¹⁷

The Southern Environmental Law Center took the legal lead. SELC attorneys filed public-records requests, commented on every permit revision, and eventually prepared the July 2025 administrative appeal of the air permit on behalf of the NAACP Memphis branch, Memphis Community Against Pollution, and Young, Gifted and Green.⁵ The NAACP national office and the Memphis branch joined as co-appellants and, in February 2026, as co-plaintiffs on the federal Clean Air Act notice that the coalition filed concerning xAI’s Southaven, Mississippi expansion.⁵

MLK50: Justice Through Journalism, the nonprofit Memphis newsroom that Wendi C. Thomas founded in 2019 to cover poverty and racial justice, carried the investigative weight. Carrington Tatum’s July 2025 reporting on the flawed air-quality modeling that preceded the permit made the technical record legible to a general Memphis audience.⁹ The Commercial Appeal, the Memphis Flyer, and the national press that Bloomberg and The Guardian subsequently directed at the story built on the MLK50 reporting.

The coalition has not stopped Colossus. The thirty-five turbines are still running as of April 2026, and Colossus 2 in Whitehaven is under active construction. The coalition has, however, built a documentary record that closely resembles the record the Cooper Square Committee built against the Lower Manhattan Expressway and the record the Black Bottom Archives is now using in the I-375 removal negotiations in Detroit.

What the atlas’s historical cases offer

Map: Historical parallels from the atlas

The Overtown essay in this atlas documents how Black civic institutions in Miami kept a decade-long record of the I-95 clearance plans before the first demolition began in 1964. The essay traces how the Miami Times, the Overtown Advisory Board, and the Colored Board of Trade produced block-by-block documentation of who lived where, who owned what, and who operated which businesses, in a record the state eventually had to confront during the belated community-benefit negotiations of the 2000s and 2010s. The atlas’s reading of Overtown is that the documentary record was the precondition for every subsequent repair, however incomplete.

Boxtown’s documentary record is older than MCAP but narrower. The Rogers and White families kept their genealogies in White’s Chapel AME Church records. The Jones Big Star Markets kept their commercial archive until the chain closed in the 1990s. The Boxtown Neighborhood Association kept meeting minutes across the annexation period. What the neighborhood did not have until 2020 was an organization whose explicit job was to document the mechanisms of destruction in real time and to publish the documentation in a form that lawyers, reporters, and future organizers could use. MCAP is now that organization.

The Black Bottom and Paradise Valley essay documents a second historical case. The Detroit freeways and the Gratiot Redevelopment Project erased a Black neighborhood in the 1950s and 1960s under planning documents that used the word “blight” to disguise the racial targeting of clearance. The Black Bottom Archives, founded in 2015, has since assembled the oral histories, family photographs, and business records that the historical organizers, pressed by the immediate demolitions, did not have time to collect. The archive now anchors the I-375 removal negotiation that Detroit People’s Platform is leading.

The Boxtown case sits between the Overtown and Black Bottom cases in time. The industrial layering that preceded xAI is largely documented, because the Memphis Sand Aquifer’s protection has required state and federal environmental review since the 1970s. The xAI layer itself is being documented as it happens, which is a rare luxury for the communities the atlas records. Memphis Community Against Pollution, Young, Gifted and Green, and the MLK50 newsroom are writing the first draft of Boxtown’s Colossus record in a form on which the subsequent repair negotiation, whenever it comes, will be able to draw.

The transferable lesson is specific. The Miami civic institutions documented the displacement plans for ten years before the bulldozers arrived. The Detroit archivists documented the displacement for sixty years after the bulldozers had departed. Boxtown is documenting the displacement as the first turbines are running. The documentation is not a substitute for stopping the campus; the coalition’s intent is to stop it. The documentation is what survives if the campus is not stopped, and what grounds any subsequent remedy.

What present organizers should borrow

The MCAP coalition template, tested in the Byhalia Connection victory and carried into the Colossus fight, is specific enough to name.

The first element is the plaintiff stack. MCAP organizes the neighborhood residents. Protect Our Aquifer runs the aquifer science. The NAACP branch provides legal standing and national reach. Young, Gifted and Green brings youth organizing and a multi-state network. The Southern Environmental Law Center carries the litigation. The Sierra Club Tennessee Chapter carries the coalition footprint into state environmental hearings. Each organization occupies a distinct role; none of them tries to do all of the roles; and the coalition distributes credit rather than concentrating it in a single spokesperson.

The second element is the press spine. MLK50: Justice Through Journalism carries the Memphis-specific investigative work. The Commercial Appeal and the Memphis Flyer carry the metro coverage. National press picks up the story only after the local record is established. KeShaun Pearson, LaTricea Adams, and the attorneys at SELC speak on the record by name, so future researchers can follow the thread through named sources rather than through anonymous officials or unnamed “community concerns.”

The third element is the factual archive. Every public-records request, every public-comment letter, every deposition, and every air-quality measurement the coalition has commissioned lives at memphiscap.org, younggiftedgreen.org, and selc.org, with cross-references to the Memphis-Shelby County Library’s local-history collection. The archive is the Cooper Square Committee’s Alternate Plan updated for the data-center fight, and it is the Black Bottom Archives’ oral-history method extended into real-time documentation.

Any community now facing a hyperscale data-center siting, a pipeline routing, a generator installation, or a transmission-corridor condemnation can adopt the structure. The specific agencies, utilities, and statutes vary by state. The coalition template does not vary. MCAP has published the template in the form of its campaign documentation and is available to consult with other communities directly.¹⁶

The atlas records the Colossus campus for what it has taken so far: the air quality of a freedmen’s settlement that spent a century under the combined load of a refinery, a coal plant, and a wastewater facility; the first metered drawdown from the Memphis Sand Aquifer for a single private customer; the ratepayer exposure that a 2,000-megawatt TVA allocation would create; and the zoning precedent that treats 364-day “emergency” waivers as routine for new hyperscale facilities. The atlas also records what Boxtown has built in response: a coalition that beat a crude-oil pipeline in 2021 and is fighting a supercomputer in 2026, with the same organizers, the same method, and an expanded archive.
