How Musk's Memphis AI Complex Became the National Symbol of Data Center Backlash

Two years ago, Elon Musk turned Greater Memphis into the proving ground for his AI ambitions, racing to stand up massive data centers and the gas-burning power plants needed to run them. That speed is now the problem. Residents living near the facilities, known as Colossus and Colossus II, describe a daily reality of turbine noise, rising utility bills and air pollution that nobody consulted them about before construction began. And their experience has become the reference point for a wave of opposition to AI infrastructure spreading well beyond Tennessee and Mississippi.

This week, New York Gov. Kathy Hochul signed a one-year moratorium on new AI data center construction in her state, a move that drew a public rebuke from President Trump, who is allied with Musk. Last week, New Jersey Gov. Mikie Sherrill signed legislation requiring data center operators to pay their fair share of electricity costs rather than passing those expenses on to residents and businesses. Both moves, along with a growing list of protests, lawsuits and local zoning fights around the country, trace back in some way to what happened in Memphis.

"When you think about what precedent Colossus has set, it hasn't been a great one," Jigar Shah, the former director of the U.S. Department of Energy loan program office, told CNBC. "It certainly is a case study for what not to do in most of the rest of the country. But from a capitalist standpoint, they got rewarded."

That reward is hard to miss. SpaceX, which acquired xAI in February and now houses the business under the name SpaceXAI, completed a record-setting IPO in June, with the Colossus facilities front and center in the pitch to investors. Google, Anthropic and Reflection AI have all signed deals to rent excess computing capacity at the Memphis-area sites, agreements collectively worth up to $2.32 billion a month, according to CNBC's reporting.

Noise, pollution and no consultation

None of that is showing up in the daily experience of people who live near the plants. Jason Haley, who lives in Southaven, Mississippi, within a mile of Colossus II, described the turbine noise as "like a form of torture." Residents told CNBC that SpaceXAI never sat down with them before breaking ground, even though the scale of the project made its impact on surrounding neighborhoods obvious from the start.

Haley helped form a group called the Safe and Sound Coalition last year to document noise levels and press both the company and local officials for changes. In March, Southaven Mayor Darren Musselwhite promised tougher enforcement on noise, but in emails reviewed by CNBC, he also told Haley he might want to consider selling his house. Musselwhite told CNBC he has "worked countless hours to mitigate noise concerns" and disputes ever telling a resident to move.

In June, Haley and other Southaven residents filed a proposed class action lawsuit against SpaceX alleging the company created a public nuisance through the noise generated by Colossus II. Neighbors near Microsoft's Fairwater Data Center in Mt. Pleasant, Wisconsin, filed a similar noise-based class action suit this month, an indication that the Memphis playbook is already being copied elsewhere.

A separate and more serious legal fight centers on air quality. In April, the Southern Environmental Law Center and Earthjustice sued SpaceXAI on behalf of the NAACP in federal court in Mississippi, alleging the company violated the Clean Air Act by running dozens of gas-burning turbines without the required permits or pollution controls. According to manufacturer spec sheets cited in the reporting, the type of turbines used at the site can emit thousands of tons of smog-forming nitrogen oxides annually, along with fine particulate pollution known as PM 2.5.

NAACP attorneys sought an emergency injunction in May to halt use of the turbines in Southaven. The U.S. Department of Justice intervened, asking the court to dismiss the case. In its motion last month, the DOJ argued that SpaceXAI's technology had been used in American military operations in Iran and was now critical to national security, and that the lawsuit threatened the country's economic and energy security. SpaceX maintains the turbines currently running are temporary and that permitted units with pollution controls are planned.

Abre' Conner, who leads the NAACP's Center for Environmental and Climate Justice, said companies like SpaceXAI tend to locate in areas that have already borne the brunt of industrial pollution, which she said deepens what she called "sacrifice zones" that residents have long fought to escape. In Whitehaven, Tennessee, a majority-Black community bordering the Colossus II fence line, longtime resident Loretta Thornton said she recently put savings into refinancing her home. Selling isn't realistic, she said, given housing costs and interest rates, and she doubts anyone would want to buy a house next to the plant anyway. "You just have to endure this," she told CNBC. "I know I cannot sell my property. Who will want to buy it, living beside this thing?"

The money doesn't always trickle down

Memphis Mayor Paul Young, who helped recruit the SpaceXAI project, points to $25 million in taxes the company paid during its first year of operation, making it the second-largest taxpaying property in Shelby County behind FedEx. Young said the city has tried from the outset to manage the downside while capturing the upside, though he acknowledged SpaceX has fallen short on some commitments, including a delayed water recycling plant meant to cut the facility's cooling water demands.

Several residents told CNBC their water and electricity bills have risen since SpaceXAI arrived. Memphis Light Gas & Water disputes any connection, telling CNBC that rates "have not been impacted" by the data centers and that a planned 4% electric rate increase over three years starting in 2024 was unrelated to data center load.

That tension, cities touting jobs and tax revenue against residents footing higher bills, is a familiar pattern. Data centers require enormous amounts of land, power and water to build and cool, but once operational they don't need large staffs, meaning the long-term employment and tax benefits can be more modest than the initial pitch suggests.

A national pattern taking shape

Public frustration extends well beyond Memphis. A Gallup poll from May found seven in 10 Americans oppose construction of AI data centers in their own communities, with 48% saying they are strongly opposed. The pushback spans projects from Microsoft, Meta, Google, OpenAI and other major cloud and AI providers, not just Musk's operation.

Even Musk has conceded the point. In an interview with JPMorgan CEO Jamie Dimon during SpaceX's IPO roadshow, he acknowledged that almost nobody wants a power plant nearby, and that doubling U.S. electricity capacity would mean doubling the number of power plants, something most communities resist.

The ripple effects are already visible in local politics and policy. Communities in Olive Branch and Jackson, Mississippi, have revised zoning rules specifically to avoid repeating Memphis's experience. In Utah, state Senate president Stuart Adams lost his Republican primary in June after backing a data center project tied to investor Kevin O'Leary, and two other local officials who supported it lost their own primary races. The NAACP has since published a guide advising communities on how to protect themselves from what it calls "dirty data" projects and how companies can structure deals to avoid the kind of conflict that erupted in Memphis.

Musk and SpaceX did not respond to CNBC's requests for comment on the backlash. SpaceXAI has acquired more than 1,100 acres in Greater Memphis for its data centers and power plant, and the original Colossus facility, built to train and run xAI's Grok chatbot, took just 122 days to come online, according to a September 2024 post from Musk announcing the milestone.

That speed built Musk an AI empire and helped fuel one of the biggest IPOs in recent memory. It also left a template that lawmakers, regulators and residents in other states are now studying closely, mostly to figure out how not to repeat it.
