Data centres will end up net suppliers of power to their communities, because a solar plant big enough to keep the machines running spills most of what it makes.

The binding constraint on AI is not chips but the physical plant around them — power, transformers, cooling and networking.

Musk says the binding constraint on AI is not chips but the physical plant around them — power, transformers, cooling, networking. Handmer says a data centre can build its own off-grid solar plant, keep the machines up 99.5% of the time and still have power left over for the town. One treats the grid as the wall; the other says you can step around it.
Rests on

Past a point it is cheaper to overbuild solar than to add batteries, because a battery kept for the rare bad day is barely used.

Data centres end up net power suppliers only because they are built the way Handmer says high-capex loads should be built: overbuild the array rather than buy batteries for the rare bad day. The spilled 75% that becomes the neighbourhood’s power is that overbuild.
