Memphis may not have enough power to accommodate enormous AI facility

An environmental group is sounding the alarm about Elon Musk's xAI Colossus facility in Memphis, which they fear will strain the city's power grid.

The facility's projected energy consumption now exceeds one-third of Memphis' current peak power demand.

Stephen A. Smith, executive director of the Southern Alliance for Clean Energy, said the initial plans estimated a 150 megawatt power load. However, Musk recently announced the project's size has grown tenfold, pushing the projected energy demand to 1,000 megawatts, or one gigawatt.

Smith noted the massive, nonstop server farm is dedicated to artificial intelligence processing.

"Memphis could handle the 150 megawatts," Smith pointed out. "It's a fundamentally different request when you're going to require your own power plant to power one facility that really doesn't employ a lot of people."

Smith explained the new buildout will expand XAI's Memphis facility from 100,000 to 1 million GPUs, a 900% increase. He noted they are deeply concerned the company intentionally hid plans for a major expansion. He believes Musk secured waivers and infrastructure commitments from the Tennessee Valley Authority under false pretenses.

Smith emphasized there are significant environmental effects. Servers generate tremendous heat, requiring cooling with large amounts of water from Memphis' pristine aquifer. However, XAI said it plans to recycle water and manage cooling effectively, even with expansion. He added generating the power itself is a challenge because Memphis Light, Gas and Water and the TVA were not prepared to start up generation as quickly as XAI and Musk wanted.

"He brought in these portable fossil gas generating units and he sought a waiver from the Tennessee Department of Environment Conservation, so they're not being covered by an air-pollution permit right now," Smith stressed. "They've got a waiver for the first year, and so they are polluting the air in South Memphis."

Smith pointed out mobile units are less efficient, consume more fossil fuel and lack advanced pollution controls. Additionally, the noise from construction affects nearby neighborhoods. He argued XAI would need to be more transparent about how it is going to generate the power and control pollution and noise.
