How many data centers are in Maryland?

How much electricity do Maryland's data centers use?

We don’t publish a state total, and the reason matters: about eight in ten facilities here never disclose a capacity, so any sum would look like a census of Maryland'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.
