How much electricity do New Hampshire's data centers use?

We don’t publish a state total, and the reason matters: about nine in ten facilities here never disclose a capacity, so any sum would look like a census of New Hampshire's data center load while leaving out the sites that stayed quiet. Each facility page shows the figure its own source states. A single large campus can draw as much power as a small city.
