Researched with AI assistance, checked by scripts. These rows were researched by AI agents reading public operator, laboratory and vendor sources, appended by scripts and checked by automated validation; no subject-matter expert has reviewed them (how this site is made). A mechanical second-reader pass has since fetched every cited source: 1350 of 1540 systems have a readable citation that names them, and 64 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 | - Homer City Redevelopment develops the 3,200 acre gas-powered campus; AWS is the anticipated end user | Homer City Redevelopment | - | Reported | gevernova.combaxtel.com |
| Power | - Seven GE Vernova gas turbines for up to 4.5 GW of on-site generation | GE Vernova | 7 reported | Reported | gevernova.combaxtel.com |

The read
Proposed AWS data center campus at the Homer City Energy Campus in Indiana County, Pennsylvania, on the site of a former 2 GW coal plant that ran from 1969 to mid 2023. Homer City Redevelopment's April 2025 announcement with GE Vernova and Kiewit describes a gas-powered campus of more than 3,200 acres with up to 4.5 GW of generation from seven GE Vernova turbines, designed for AI and high-performance computing demand. Baxtel reports that Amazon confirmed talks with the developer in August 2026 with no definitive agreement, and that a preliminary land development plan filed on 28 August 2026 (PIT100 Masterplan) shows 36 data center buildings with AWS as the anticipated end user, built in phases to about 2036; county commissioners tabled the application after a 9 September meeting. The 4.5 GW is generation capacity, not data center load, and no accelerator type or count is public. AWS's other Pennsylvania campus is aws-susquehanna-campus.
