6 is a number an order of magnitude too small unless you live in a desert. If you live in a city, it's probably closer to two orders.

To support 60 assuming ~50% utilization you'll need 1MW per 1 sqkm additional power. This isn't a small number. The grid anywhere is absolutely not ready for such a rapid increase of load. There isn't enough refined copper produced worldwide to upgrade the grid. I mean setting up a copper mine on 16 Psyche is not a batshit insane idea here.
