Could a proposed North Dakota data center draw nearly as much power as Garrison Dam can generate?

Geronimo Power’s proposed Harmony Energy Park data center in Harmony Township, North Dakota, would initially require up to 540 megawatts of electrical service. The proposed demand is about 93% of Garrison Dam’s 583.3-megawatt installed generating capacity, according to figures cited from a U.S. Department of Energy research presentation.

The project would include two primary data center buildings and supporting infrastructure on a 640-acre site in Cass County. Geronimo Power says the facility could expand beyond its initial power allocation based on customer demand and utility requirements; the comparison concerns maximum power demand rather than annual electricity use or generation.
