Site selection

Reading order

Start with the cadastral identity and the person or company that can actually sell or lease. A marketed “data-center site” can be a hope attached to a fastighetsbeteckning. Confirm the boundary, remaining lease term and authority to bind before you rank cooling or fiber. Until title and those rights sit in the folder, later cells in the matrix are commentary on someone else’s land.

Name the network owner and the latest written position before you read a map colour. Ask whether that paper is an inquiry reply, a reservation or a signed connection agreement, and which import capacity, voltage and point of connection it describes. Svenska kraftnät’s indicative transmission-network capacity map does not replace that letter and does not show capacity in the underlying regional or local network.

Only then open the municipal plan file and the environmental topics the design would trigger. An översiktsplan is municipal guidance for the whole municipality. A detaljplan is the binding instrument for a defined area. Political enthusiasm is neither. Fiber, neighbours and expansion space come after those two legal layers, because a diverse duct does not cure a use that the plan forbids.

• Cadastral unit, seller or lessor, and authority to bind.
• Network owner, voltage, dated written position and what load it names.
• översiktsplan guidance and detaljplan status for the actual plot.
• Environmental topics the cooling, fuel and land design would trigger.
• Diverse fiber entries, neighbour uses and space for the next hall.

How Swedish site choice actually works

Several Swedish institutions speak to a plot, and they do not share one inbox. The municipality plans land use under the Planning and Building Act and later examines bygglov. The local or regional network owner answers a connection request at the property. Svenska kraftnät appears when the load reaches transmission questions. Energimarknadsinspektionen explains the four bidding areas. None of those letters is a substitute for the others.

SE1 Luleå, SE2 Sundsvall, SE3 Stockholm and SE4 Malmö exist so transmission constraints show up in the wholesale price. They do not allocate spare megawatts to a cadastral unit. A hydropower-rich national mix, as described on Energimyndigheten’s system pages, is useful context. It is not a yes to a hall outside Falun, Staffanstorp or Sollefteå. Separate the energy story from the connection offer.

Land-use permission and electrical permission travel on different clocks. A plot can sit in an industrial detaljplan and still wait for a reinforcement study. Another plot can have a constructive network letter and still need a new detaljplan, samråd and granskning before bygglov is even the right form. Treating the greener of those two stories as “the site is ready” collapses two files into a slogan.

Cooling, backup fuel and fiber change what “the same plot” means. Outdoor-air designs, evaporative systems and liquid loops ask different things of water, noise and neighbours. Two carrier logos on a slide are not two independent building entries. Expansion space is a second hall’s land, power and plan question, not a dashed line on a marketing masterplan. Write those differences as separate cells.

• Municipality — plan instruments and later bygglov, not the wires.
• Network owner — connection file at the property.
• Svenska kraftnät — transmission questions and indicative maps.
• Bidding area — wholesale price signal, not a reserved MW allocation.

What named primary sources show

Business Sweden’s Site Finder presents industrial land as a general investment tool. It is a starting catalogue, not a substitute for the network owner’s letter or for Boverket’s explanation of översiktsplan and detaljplan. Svenska kraftnät’s own framing of the transmission capacity map is that it does not replace the formal connection process and does not show underlying-network capacity. Energimarknadsinspektionen’s bidding-area pages define SE1–SE4 as market areas, not as plot scores.

Operator notices show how little a location name settles. Meta’s Luleå careers page describes an operator campus from 2013, outdoor-air cooling and local hydropower. It does not publish a current megawatt figure that this register can store. Microsoft’s 16 November 2021 Sweden-region text names Gävle, Sandviken and Staffanstorp and does not publish facility megawatts in the cited materials. AWS’s 12 December 2018 Europe (Stockholm) launch pages do not name the municipality on the cited texts.

Land steps and campus stories are also not interchangeable. evroc’s 3 February 2025 notice records a land and building-rights purchase at Arlandastad, a design of up to 16,000 GPUs and a stated investment intention; it does not state megawatts. atNorth’s Sweden pages describe SWE01 in the Stockholm metro and a 50-hectare development at SWE04 Sollefteå / Hamre Långsele. GleSYS documented a 1 October 2020 start of heat delivery in Falkenberg. Those are dated operator facts about those projects. They are not a ranking of Swedish municipalities and not a connection study for your shortlist.

Common misreads

The most expensive misread is to treat a green pin as a developable file. A pin can mean the municipality welcomes industry, that a landowner is marketing hectares, or that an operator already built somewhere in the same county. Those are three different facts. A welcome page that lists “good conditions for data centers” is marketing unless it cites an adopted plan, a dated network letter or a committee minute that names the project.

A second misread is to treat bidding-area price or a national generation mix as local spare capacity. SE1 can be cheap in a given hour while the regional wire to the plot is constrained. The reverse is also possible. EcoDataCenter’s Falun file in this register keeps several megawatt sentences on separate rows — commissioned buildings, a later campus sentence, a marketing “available power” figure — and does not add them. Do not import that discipline and then invent a municipal spare-MW total from a map colour.

A third misread is to copy another operator’s location logic onto your plot. Meta’s outdoor-air story is about that Luleå campus. Microsoft’s named municipalities are about that 2021 region. AWS’s unpublished municipality on the cited launch pages is a source gap, not a hint. atNorth’s Sollefteå hectare figure is a development description. None of those sentences answers your detaljplan, your noise case or your connection offer.

• A Site Finder pin is not a connection study.
• A cheap SE1 hour is not reserved capacity at the plot.
• A municipal welcome is not a detaljplan.
• An operator campus in the same bidding area is not your file.
• Unknown megawatts stay unknown; they are not stored as zero.

What to ask next

Ask questions that produce a dated paper, not a warmer meeting. For each shortlisted plot, the useful product is a one-page matrix with six cells filled or marked missing: grid, plan, environment, fiber, neighbours and expansion. Assign a named specialist where the cell is legal or technical. An empty cell is a finding. A verbal assurance without letterhead is still empty.

When the counterpart is a municipality, ask which office handles the case, which committee adopts a detaljplan or grants bygglov, and which minutes already name the project. When the counterpart is a network owner, ask for the latest written position and which reinforcements, if any, sit on the critical path. When the counterpart is a landowner, ask who can sign and which easements already cross the land.

• What is the fastighetsbeteckning, and who can bind it this quarter?
• Which network owner wrote last, on which date, about which megawatts?
• Is there an adopted detaljplan, a pending plan, or only an översiktsplan?
• Which environmental investigations has anyone actually commissioned on this land?
• How many physically diverse building entries exist, and who owns them?
• What land, power and plan would a second hall require?

What this does and does not prove

This page is orientation for comparing Swedish plots. It explains why a matrix of dated papers beats a national ranking, and why bidding areas, Site Finder pins and operator campuses answer different questions. It does not recommend a municipality, score Sweden against the rest of the Nordics, or convert a missing cell into a zero. It is not a site-selection report, a valuation or a permit decision.

Nothing here allocates capacity, adopts a detaljplan or binds a network owner. If a figure is unpublished on the cited primary page — Meta’s current Luleå megawatts, Microsoft’s facility megawatts, AWS’s municipality on the 2018 launch texts — this register stores the gap. Counsel, a grid consultant and a planner who have read the actual files still have to close the cells that matter for your case.

• Proves: which questions belong in a Swedish comparison file.
• Does not prove: that any named plot is available or connectable.
• Does not prove: a universal Swedish time-to-power or spare-MW map.
• Does not replace: network-owner letters, plan documents or legal advice.
