Phase 1 seed dataset, compiled by hand. These rows were built from public operator, laboratory and vendor sources. A mechanical second-reader pass has since fetched every cited source: 1092 of 1153 systems have a readable citation that names them, and 40 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

What this machine is made of
One row per supplier relationship. “Supplier at build” is the company that shipped the part at the time; where that company has since been acquired, the parent it rolls up to today is shown beside it. That distinction is what makes ticker-level aggregation possible across a thirty-year dataset.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| Integrator | - Meta designs, builds and operates the 1 GW Lebanon, Indiana AI data center with closed-loop liquid cooling | Meta Platforms | - | Reported | about.fb.com |
AI datacenter metrics
Figures beyond an accelerator count, each with who stated it. What can and cannot be compared across AI datacenters.
| Metric | Value | As of | Basis | Note | Source |

| Grid | Boone REMC | - | planned | 2026-10 | Operator stated | Distribution co-op, called Boone Power in the info sheet, named alongside Wabash Valley Power Alliance for the Lebanon campus; no MW stated. | datacenters.atmeta.comabout.fb.com |
| Wind and solar | - | 409 | contracted | 2026-10 | Operator stated | Meta says four Indiana projects it supports add 409 MW of new clean energy to the grid. Used to match its electricity use; not a direct supply to the site. | datacenters.atmeta.com |
How AI campuses are powered: capacities are what the operator, utility or filing states, not what has been delivered.
The read
Meta's 1 GW AI data center campus in Lebanon, Boone County, Indiana, its second Indiana site, announced at groundbreaking on 11 February 2026 with more than 10 billion dollars of investment, a water-efficient closed-loop liquid-cooled design and about 4,000 construction jobs at peak. Meta does not give an operational date or hardware; trade coverage gives late 2027 or early 2028 for full operation, which is not recorded as a fact here. The only fetched source is Meta's own announcement, so the tier is reported.

Source check
We fetched this system's own citations and recorded whether each page actually mentions it. This is a corroboration signal, not a fact check, and it is published so you can see how well the sourcing holds up rather than take it on trust.
