Off-grid data centers aren't the panacea that some AI firms hoped

Axios Axios

Local backlash and reliability concerns are challenging the vision of an https://www.axios.com/technology/automation-and-ai" target="_blank">AI boom built quickly using large off-grid data centers.

Why it matters: If giant projects stumble, trillions of dollars in AI investment and the industry's plans to rapidly expand data centers could be at risk.


The big picture: In an effort to speed AI development, some companies are building data centers powered mainly by onsite generation rather than waiting years to connect to the electric grid.

  • There are 59 data centers with a combined capacity of about 90 gigawatts that plan to build their own power "behind-the-meter" using sources like gas turbines, generators and fuel cells, https://cleanview.co/reports/behind-the-meter-data-centers" target="_blank">according to a report from research firm Cleanview.
  • A smaller subset is trying to run large campuses mostly on behind-the-meter power as a way to move more quickly than the local utility and the grid can.
  • Infrastructure risk analysis firm Occam Edge https://occamedge.substack.com/p/dark-gigawatts" target="_blank">tracks 12 projects where onsite power is the primary serving supply, representing about 10.6 GW of announced capacity.

State of play: Recent hiccups are highlighting the challenges that come with bypassing the grid.

Local residents complained of burning lungs and 60-decibel level noise, and a supervisor called for new laws to regulate generators.

Catch up quick: Chief developers of this off-grid approach include OpenAI, and its partners Oracle and Crusoe, which have worked on OpenAI's Stargate campuses.

What they're saying: Critics argue off-grid data centers could prove https://www.distilled.earth/p/openais-stargate-data-centers-are" target="_blank">slower and more costly to deploy, https://occamedge.substack.com/p/dark-gigawatts" target="_blank">less reliable to run, and more expensive than expanding the electric grid.

  • "This is a flimsy way to deploy AI," says energy investor Jigar Shah, who https://www.latitudemedia.com/news/open-circuit-the-off-grid-data-center-fantasy/" target="_blank">predicts much of the bullish off-grid deployment figures won't materialize.
  • Power engineers are worried that off-grid data centers won't meet reliability targets, says Occam Edge founder and CEO Christian Okoye, who https://occamedge.substack.com/p/dark-gigawatts" target="_blank">compares "Dark Gigawatts" to the "Dark Fiber" of the dotcom bust.
  • "It's a time of desperation," says Josh Wong, founder and CEO of ThinkLabs AI, which helps utilities find more capacity on their current grids. "The [off-grid] business model is bolt-on."

Follow the money: Investors are lacking insight into the reliability of off-grid data centers, says Okoye.

  • Investors faced with the uncertainties of off-grid data centers could decide not to underwrite them.
  • S&P Global Ratings https://finance.yahoo.com/markets/stocks/articles/oracles-credit-risk-nears-18-151000986.html" target="_blank">recently downgraded Oracle's long-term issuer credit rating to BBB- from BBB, just one step above junk status, due to its massive data center spending, which includes investment in onsite power infrastructure.
  • Trillions of dollars are riding on whether large off-grid data centers can work as advertised, justify their added cost and win local support.

What's next: More high-profile problems building and running off-grid data centers could lead to a reckoning that the AI boom will be a lot more grid-powered than many AI companies hoped.
