Sesterce Kaipola AI Campus
Also known as Sesterce Jämsä
Operated by Sesterce at Former Kaipola Paper Mill Site .
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.

The read
Sesterce's planned 10 billion dollar AI campus on the former Kaipola paper mill site in Jämsä, central Finland: a 200 MW first phase expanding to 600 MW, with a stated aim of more than 1 GW in Finland. Sesterce says it would reuse the mill's grid connection, water systems, buildings and logistics, use liquid cooling, and add 1 MW of new renewable generation to the Finnish grid for every MW consumed within ten years of operations starting, with construction expected to begin in 2026. The City of Jämsä's comment, quoted by Baxtel, is that the project is an opportunity only if it moves from plans to implementation. Only one trade source (Baxtel, 8 October 2026) was available, no Sesterce primary page was fetched, and no GPU type or count is given. Sesterce's earlier site is sesterce-marseille.
