3 data centers and projects on our map in Idaho, including 2 projects we track in detail. Each one links to its source. Below: where they are by county, the projects in the news, and the latest reporting from both sides.
See Idaho on the map. Existing facilities come from OpenStreetMap, a community-maintained public map that is incomplete; proposed, under construction and blocked projects are tracked one by one from news, filings and official records.
