All DCs should be assessed for their impact on power supply and related utilities, and regulated to reduce impact on the community. All of them.

There's some potential to use aspects of temperature control to manage power if you can e.g. soak energy into heat or coolth, and time-shift the energy investment. Regarding electrical power to racks, I don't thing DC's have much options for load shedding or surge, but perhaps hyperscalers do actually have a way to do this?
