Common questions about power in Cass County
How long does it take to get power for a data center in Cass County, ND?
The median wait for a project still in the interconnection queue in Cass County is 2.3 years. Across the US, most large loads are quoted three to seven years depending on the market and whether network upgrades are needed. 1 projects in Cass County have reached energization and 13 were withdrawn, so the withdrawal rate here is a better guide to risk than any single quoted timeline.
How much capacity is available in Cass County, ND?
1.1 GW is currently requested across 4 active interconnection requests, and 200 MW has actually been built. A queued megawatt is a request, not deliverable capacity — most queued projects are never built. For deliverable offtake capacity at a specific substation you need a utility study, not a queue.
