Elon Musk reportedly acquires mobile turbine operator as xAI faces pollution scrutiny

Elon Musk has reportedly acquired APR Energy, a supplier of mobile gas and diesel power equipment, as his AI company xAI seeks fast ways to supply electricity to its expanding data center operations.

Fred Lambert reports for Electrek that the transaction surfaced in a Federal Trade Commission early termination notice, rather than through a public announcement. Based on disclosures involving a minority investor, the deal appears to value APR Energy at more than $1 billion.

APR Energy operates a fleet with more than one gigawatt of generating capacity. Its equipment includes trailer mounted gas turbines and engines that run on natural gas or diesel. These units can be installed quickly and reach operating capacity in minutes, offering a faster alternative to building a permanent power plant or waiting for a grid connection.

The reported acquisition comes as xAI faces legal and regulatory pressure over gas turbines used to support its Colossus data center projects near Memphis, Tennessee. The sites train and operate Grok, xAI’s chatbot and AI platform.

Unpermitted turbines near Memphis

Disha Raychaudhuri and Valerie Volcovici report for Reuters that xAI has installed 59 natural gas turbines for its Colossus 2 project without federal clean air permits, according to correspondence between company representatives and regulators. At least 57 of those units are located in Southaven, Mississippi, close to the Tennessee border and the Memphis data center.

xAI had previously said it was operating 27 unpermitted turbines for Colossus 2 and argued that permits were not required. Mississippi regulators and xAI have said the equipment qualifies as portable or temporary, and therefore does not need an air permit under their interpretation. The U.S. Environmental Protection Agency has said that temporary turbines exceeding emissions limits still require permits, while also considering regulatory flexibility for portable units.

Reuters calculated potential annual emissions from 30 turbines at the Southaven site using manufacturer data and an assumed operating level of 80 percent capacity. The analysis found that the turbines could emit nearly 2,500 short tons of nitrogen oxides, 4,000 short tons of carbon monoxide and 22 short tons of formaldehyde each year.

Nitrogen oxides contribute to smog and can worsen respiratory illnesses. Formaldehyde is a carcinogen. The potential emissions would exceed the federal threshold that generally triggers permitting for major pollution sources.

Environmental justice concerns

Civil rights and environmental groups, including the NAACP, the Southern Environmental Law Center and Earthjustice, have sued to stop the turbine operations. They argue that the units should be regulated under the Clean Air Act and that the project adds pollution to communities already facing high respiratory disease rates.

Reuters’ analysis found that residents near the facilities are disproportionately Black. Within five miles of the project on the Tennessee side, about 94 percent of residents are Black, compared with 52 percent in surrounding Shelby County. In Mississippi’s DeSoto County, about 46 percent of residents within five miles are Black, compared with 33 percent countywide.

The U.S. Justice Department has also intervened in the dispute. In a court filing, it argues that restricting turbine operations could affect national security interests because xAI systems support U.S. military operations.

The reported APR purchase would give Musk access to a ready made fleet of mobile power equipment at a time when AI companies are competing for electricity. It also sharpens the debate over whether rapidly growing AI infrastructure can bypass the environmental reviews and grid planning normally required for large power projects.
