Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.
Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.
Reported lifecycle history
- Proposed
Lex Developments sought a conditional use permit for an AI data center, reported by BoiseDev as valued at $2.6 billion, at the former Hoku Materials polysilicon plant site (River Park Complex).
Underlying source - Cancelled
Pocatello City Council voted 4-1 to uphold the Hearing Examiner's denial of the conditional use permit, ending the local approval path as of retrieval.

Source notes
BoiseDev (14 May 2026) described the developer's application, later denied, as a $2.6 billion data center, with a headline of "$2 billion+"; it was not a built or committed project. As of October 2026, no investment figure is recorded: BoiseDev's valuation is a press figure that no other readable cited source corroborates. As of October 2026, no MW capacity or secured tenant was stated in the KIFI report. BoiseDev (14 May 2026) gives the site as 49 acres and reports an Idaho Power letter citing a load increase of more than 100 MW, with the site expected to use 100 MW by 2031. As of October 2026, none of the three cited sources names a secured tenant. This pin is a Pocatello city-centroid placeholder (approximate): as of October 2026, the KIFI report gives a street address for the former Hoku polysilicon site (1800 River Park Way), but neither BoiseDev nor KIFI gave parcel boundaries or coordinates, and OpenStreetMap has no feature for it. It is not a claim about where on the Hoku parcel the proposal sat, and it is not co-located with the FBI Grey Wolf Data Center (tracked separately as of September 2026), whose pin was corrected to its own OSM building POI 4.0 km north.
In February 2026 Idaho Power sent Lex principal Gus Shultz a letter about the site as 'Project IV West'. It described a 'significant load increase' of more than 100 MW, with the site expected to use 100 MW by 2031. The proposal covered seven 100,000 sq ft buildings. When the city's Water Pollution Control asked about wastewater discharge, Lex did not answer directly.
