xAI is reportedly running eight converted jet-engine turbines in Mississippi to help power Colossus 2

What changed

The New York Times reported on 3 November, as summarised by TechCrunch, that xAI has installed eight converted jet-engine turbines at a site in Mississippi to help power its Colossus 2 data centre in Memphis, citing state permits and satellite imagery. The units come from ProEnergy, which rebuilds a GE aircraft engine to burn natural gas; ProEnergy's own website rates its PE6000 aeroderivative unit at 50.2 MW gross. TechCrunch notes such units are less efficient and pollute more than turbines built for conventional gas plants, and Tom's Hardware reports the Southern Environmental Law Center has challenged the Mississippi approval. xAI did not publish the installed capacity; this is a reported item and no total for the site is given here.
