Common questions about power in Ada County

How long does it take to get power for a data center in Ada County, ID?

The median wait for a project still in the interconnection queue in Ada County is 3.5 years. Across the US, most large loads are quoted three to seven years depending on the market and whether network upgrades are needed. 14 projects in Ada County have reached energization and 51 were withdrawn, so the withdrawal rate here is a better guide to risk than any single quoted timeline.

How much capacity is available in Ada County, ID?

2.0 GW is currently requested across 11 active interconnection requests, and 531 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.

Is Ada County, ID a good site for a data center?

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. The other half — the state policy position, moratoriums and large load tariffs — is on our Idaho policy page.
