Every number has a receipt.
Source, timestamp, and a link back to the original publication travel with every value, so your analysis holds up when someone checks it.
About Substralis
The source-backed European grid map for datacenter scouts.
A scout asking where can I put 200 MW of compute in Europe reads half a dozen connection registers, headroom maps, and market feeds at once — each in a different shape, none with a clean evidence trail. Substralis reads them the way the source intended and keeps the trail back to the publication on every value. Norway is live today; the rest of Europe lands country by country, as fast as the data lets us.
Why now
Power is the new constraint on where things get built.
Across 16 EU member states and Great Britain, over 1,700 GW of renewable and hybrid projects sit in grid-connection queues (Energy Storage Europe, December 2025). Datacenters compete for the same megawatts as industry, storage, and new generation. The scouts choosing where compute gets sited make decisions with consequences measured in years and hundreds of millions.
The data exists — every TSO and DSO publishes something — but in incompatible shapes, often as PDFs or PowerBI scrape targets. The EU's December 2025 grid-connections guidance pushes for transparent queue disclosure across the bloc and binding rules are expected late 2026 / early 2027. Substralis is the layer above the publications: source-backed, evidence-trailed, and ready the day each new feed opens up.
Principles
Three commitments behind every number on the map.
02
History, not just today.
Queues move through stages. We keep every change, so yesterday's portal refresh becomes a record you can query — not a screenshot you lost.
03
Faithful to each source.
Headroom, queues, and markets are published in different shapes. We preserve those differences instead of flattening them into a false average.
Who it's for
Datacenter scouts. And the people who fund their decisions.
The job starts the same way every time: a brief lands — find ≥100 MW within this region by this date — and the scout opens a dozen tabs to figure out where capacity might exist, how real the existing reservations are, and what just moved at each candidate node.
Substralis is the working surface for that scout, and the source trail the real-estate, infra, and finance approvers will ask for next. Norway is free; Great Britain and Denmark are paid launch markets. Sweden and Finland remain future-feature countries while their source intelligence matures (see per-country coverage).
The team
Built for teams that need to find real megawatts.
Substralis turns scattered European grid publications into a source-backed surface for datacenter site selection. If you want to talk about coverage, partnerships, or a walkthrough of the private terminal, write to us.
