Common questions about power in Mower County
How long does it take to get power for a data center in Mower County, MN?
The median wait for a project still in the interconnection queue in Mower County is 1.0 years. Across the US, most large loads are quoted three to seven years depending on the market and whether network upgrades are needed. 2 projects in Mower County have reached energization and 8 were withdrawn, so the withdrawal rate here is a better guide to risk than any single quoted timeline.
How much capacity is available in Mower County, MN?
1.0 GW is currently requested across 5 active interconnection requests, and 300 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.

This page gives you the power half of that answer: what is queued, what has been energized, how long the wait runs, and which large load interconnection requests are already recorded nearby.
