Musk Confirms Second Memphis xAI Site Could Use One Gigawatt of Power

Samuel Hardiman, at The Daily Memphian earlier today:

MLGW’s maximum electricity demand of all time is about 3,500 megawatts, or three-and-a-half gigawatts. Its power use is weather dependent: In the summer, MLGW uses 2,800 to 3,000 megawatts, while during the winter, it’s 1,700 to 1,800.

It remains to be seen whether MLGW and the Tennessee Valley Authority, which provides energy to the region, have enough electricity to serve the new xAI investments. It is also not clear how many semiconductors, known as graphics processing units, or GPUs, the site would use to run the data center.

It’s unlikely that MLGW and TVA will have that sort of power available by the time the second site is operational, and there’s plenty of evidence to back that up.
