Norwegian paper group Norske Skog has ended its data centre cooperation with operator Green Mountain at the Saugbrugs mill in Halden and will look for a new industrial partner. The company says it still intends to develop an 80–100MW data centre opportunity on surplus land at the site in south-east Norway.
What happened
In a stock exchange announcement issued on the evening of 1 November, Norske Skog said its letter of intent with Green Mountain had expired on 31 October and that the two parties had agreed not to renew it. The release did not give a reason for the decision. Green Mountain had signed the letter of intent earlier this year to study the feasibility of a data centre at the Saugbrugs industrial site.
Chief executive Geir Drangsland said the group would keep exploring the opportunity and begin “the process of identifying a new partner”. According to Norske Skog, several data centre developers have already shown interest in a revised version of the project.
The site and the numbers
- Planned capacity: 80–100MW, according to Norske Skog.
- Location: land at Saugbrugs in Halden that is no longer used for fibre processing or paper production.
- Planning: Halden municipal council recently adopted a planning programme for data centre development on that land.
- Assets: the company highlights significant available power capacity and existing industrial infrastructure.
Norske Skog presents the data centre as one strand of a wider plan for Halden, alongside investment in its PM6 paper machine and the work of Norwegian Nuclear Decommissioning (NND), the state agency that earlier this year agreed to buy part of the Saugbrugs property. The company’s shares fell almost 5% on the day of the announcement.
Context: mills turning into powered land
Halden is the latest example of Nordic pulp and paper sites being marketed as data centre land. Former mills typically come with high-voltage grid connections, water access and industrial zoning, all of which are scarce for new developers. In Finland, Sesterce has announced plans for a large AI campus at a former paper mill in Jämsä, and several Norwegian and Swedish industrial sites are being repositioned in the same way.
The Norwegian backdrop is less straightforward than a few years ago. Data centre electricity use in Norway has risen sharply, and political parties have recently floated a temporary pause on new data centres, a debate this site covered on 2 November. A developer taking on Saugbrugs will need to fit within whatever grid allocation and permitting rules emerge from that discussion.
Why it matters for modular and edge in Europe
Brownfield industrial sites with existing power are one of the most natural homes for factory-built data halls and containerised capacity. Prefabricated modules can be dropped into cleared mill buildings or yards in phases, allowing an owner to monetise available megawatts long before a full campus is designed and financed. An 80–100MW site with an adopted planning programme and no anchor partner is precisely the kind of opportunity where phased, modular delivery can reduce up-front risk for a newcomer.
The collapse of the Green Mountain arrangement also shows that a letter of intent on powered land is not a project. Suppliers of modular systems in the Nordics should expect more sites to change hands, or partners, before construction contracts are signed.
