Danube InGrid is one of the larger grid-modernisation programmes in Central Europe. It is a smart-grid buildout led by Slovakia's transmission system operator SEPS with the regional distribution operator Západoslovenská distribučná (ZSD, part of the ZSE/E.ON group), co-financed by the European Union under the Connecting Europe Facility. Its purpose is exactly the thing data center development usually waits for: reinforced high-voltage infrastructure and smarter distribution in the Bratislava region.
The programme is being completed on DC01SK's doorstep. A new switching station at Vajnory is publicly slated for completion at the end of 2026, and two 110 kV transmission lines cross land adjacent to the site, held in common ownership. Grid-adjacent here means named infrastructure with public timelines, physically next to the site.
On-site power today is a construction-ready ~3 MW, enough for site works and not for a campus. We say so plainly. The path toward roughly 200 MW is staged: a first uplift targeted within about ten months of a counterparty's commitment, further phases over roughly twenty-four months, worked through in active engagement with ZSD. Every element of the path is stated as built, permitted or planned.

Frequently asked questions
What is physically in place today, as opposed to slated?
On-site, construction-ready power today is ~3 MW, enough for site works and not for a campus, and we say so plainly. Next door, the infrastructure is named and dated: two 110 kV transmission lines cross adjacent land held in common ownership, and the Vajnory switching station is publicly slated for completion at the end of 2026. Every element of the power path is stated as built, permitted or planned; what it means for an occupier's programme is set out on For tenants.
Is any of the ~200 MW pathway contracted?
No contracted power is claimed on this site, and the pathway is not presented as an allocation. What is stated is ~3 MW construction-ready today, then a staged pathway toward roughly 200 MW worked through in active engagement with ZSD, with a first uplift targeted within about ten months of a counterparty's commitment and further phases over roughly twenty-four months. How the stages map to a specific requirement depends on the counterparty conversation; start at Request more info.
What is Danube InGrid, and why does it matter here?
Danube InGrid is a smart-grid buildout led by Slovakia's transmission system operator SEPS with the regional distribution operator ZSD, part of the ZSE/E.ON group, co-financed by the European Union under the Connecting Europe Facility, and one of the larger grid-modernisation programmes in Central Europe. It matters because it is being completed on DC01SK's doorstep: grid-adjacent here means named infrastructure with public timelines, physically next to the site.
