Opposition and litigation at this site
Nothing on record as of September 12, 2026. No lawsuit, organized opposition, or contested hearing over Idaho National Laboratory Collaborative Computing Center (C3) in Idaho Falls, Bonneville County, Idaho appears in the sources this registry tracks. That is an absence in our sources rather than a finding that none exists, and local opposition often predates any coverage a national dataset would pick up.
If you live near this site and something is happening that this page does not show, that is worth telling us. Send us the document and it goes in the record with the source attached. For sites where opposition is already established, see every contested site we track.
Notes on the record
High-performance computing data center on INL's Research and Education Campus (REC) in Idaho Falls -- distinct from INL's much larger remote desert 'Site' reservation (see the separate Aalo Atomics record in this batch). Houses DOE/INL supercomputers including Sawtooth, Hoodoo, and Bitterroot, supporting nuclear-energy modeling/simulation, materials science, and data science research; remote access is provided to Idaho university researchers via the Idaho Regional Optical Network. Built alongside the adjacent Cybercore Integration Center (80,979 sq ft) as part of a combined ~148,000 sq ft project; C3 itself is variously reported as 66,520 sq ft (general contractor JE Dunn) and 73,000 sq ft (engineering subconsultant AEI), and its power capacity is similarly inconsistent between fetched sources -- JE Dunn describes an '8MW High Performance Computing (HPC) Data Center with 2MW of redundancy' and a 'Day 1 installation of 4MW capacity,' while AEI's page states '1.5 MW total power'; these were not reconciled and no capacityMw field is recorded here pending a source that resolves the discrepancy. Completed circa 2022 per JE Dunn's project metadata. No exact street address was given in either source fetched.
What the record does not establish, and the document that would
In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.
- Power capacity in megawatts
- Cooling method and water use
- Tax abatements or other public subsidy
- Permanent jobs promised
- Land area
- How the community has received it
- Which utility serves it
Which document closes each gap
- Power capacity in megawatts
- The utility's large load service agreement, the interconnection request in the grid operator's queue, or the electrical site plan in the permit file.
- Cooling method and water use
- The water service agreement, any groundwater appropriation permit, and the mechanical narrative in the site plan.
- Tax abatements or other public subsidy
- The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
- Permanent jobs promised
- The economic development application or incentive agreement, which usually states a job commitment and a clawback.
- Land area
- The rezoning application, the plat, or the deed recorded with the county.
- How the community has received it
- Planning commission and governing body minutes, public comment records, and any petition or lawsuit filed in the county.
- Which utility serves it
- The electric service agreement or the utility's filing with the state public utility commission.
