Electricity areas

Reading order

Read the official area names first. Energimarknadsinspektionen publishes the four bidding areas and the logic that they exist so constraints appear in price. Then place the municipality you care about on that map: Luleå and Boden in SE1, Gävle and Sandviken in SE2, Stockholm and Falun in SE3, Staffanstorp and Falkenberg in SE4. Those assignments follow the official names, not a DataCenterSweden score.

Only after the place is seated should you read hourly price differences, and only as wholesale-market facts. A cheap hour in SE1 does not prove that a new hall can connect next year. Then open the 2026–2027 review as a dated government assignment, not as a done redesign. Keep the network owner’s connection file in a fourth folder. Area, price, review and connection are four objects.

• Seat the municipality in SE1–SE4 using the official area names.
• Treat price spreads as hourly wholesale facts, not as spare MW.
• Read the May 2026 assignment and the 29 January 2027 due date as open work.
• Keep the network owner’s letter out of the area folder.

Why four areas exist

Bidding areas are a market mechanism. When transmission between parts of the country is constrained, the wholesale price can separate so that the constraint is visible to producers and consumers in each area. SE1 Luleå, SE2 Sundsvall, SE3 Stockholm and SE4 Malmö are those Swedish areas. The names are the official area names. They are not a ranking of how easy it is to build a hall.

A project in Luleå or Boden therefore trades in SE1. A project in Gävle or Sandviken trades in SE2. Stockholm, Falun and Arlandastad sit in SE3. Staffanstorp and Falkenberg sit in SE4. That seating tells you which hourly price series to look at. It does not tell you whether the regional or local network can accept the load, and it does not tell you what Svenska kraftnät would say about a transmission-level tap.

Price differences between areas can be large or small depending on the hour. A single print is not a year. A year is not a connection study. Network tariffs are a further layer charged by the owner of the wires and are not the bidding-area price. Skatteverket’s energy-tax rules are a further layer again. The area map explains one component of wholesale formation. It does not print the bill.

How to read the four areas

Read the area as a price zone, then read the municipality as a planning and connection file. Meta’s Luleå campus sits in SE1; that does not transfer a hydropower sentence onto a Boden plot as allocated power. Microsoft’s named sites split across SE2 (Gävle, Sandviken) and SE4 (Staffanstorp); that split is a reminder that one operator region is not one bidding area. AWS Europe (Stockholm) is named for a region, not for a published municipality, and sits in the SE3 conversation only as a market label.

Falun, in SE3, is a useful check on the “north is cheap, therefore connectable” slogan. EcoDataCenter’s Falun file is an operator campus with dated megawatt sentences that belong in the capacity note, not in this area note. Falkenberg, in SE4, is a useful check on the opposite slogan that the south cannot host halls. GleSYS operates there; the area still does not publish spare megawatts for the next industrial plot. Sollefteå developments sit in the SE2 geography and still need their own network-owner file.

What named primary sources show

Energimarknadsinspektionen’s bidding-area pages are the plain statement of SE1–SE4 and of why the areas exist. Svenska kraftnät’s analysis pages record the authority’s work on the area construct. Neither page is a connection queue for Luleå, Falun or Staffanstorp. The government press notice of 29 May 2026 records an expanded assignment to Svenska kraftnät to analyse alternative divisions, with a report due 29 January 2027.

An EU-wide review reported in April 2025 did not propose changing Sweden’s four areas. That sentence is a dated European outcome, not a Swedish redesign. Until the 2027 report is published and any later legal change is made, SE1–SE4 remain the operative areas. DataCenterSweden does not treat the assignment as if the map had already moved.

Svenska kraftnät’s indicative transmission-network capacity map is a different artefact. It can be read beside the area map as a transmission-level prompt for a load near Gävle or Falkenberg. It still does not replace formal connection and still does not show underlying-network capacity. Do not merge the two maps into one slide that says SE1 has room.

Open review, not a done deal

The May 2026 assignment is real work with a real due date. It is not a connection offer for a hall in Luleå, and it is not a promise that SE4 will disappear before a Staffanstorp project reaches energization. Readers who need a price scenario for 2027 still have to label the area map as today’s operative map and the review as open. Inventing a new Swedish area set before the report exists would be a fabrication.

If a land brochure says “Sweden is moving to fewer areas, therefore this plot is safer,” ask for the statute, not the slogan. The April 2025 EU-wide review did not propose changing the four Swedish areas. The later national assignment may or may not lead to a legal change after January 2027. Until it does, contracts, tariffs and market systems still run on SE1–SE4.

Common misreads

The first misread is to treat a cheap SE1 hour as proof that Boden or Luleå can connect a new hall. Price is not allocation. The second is to treat a dear SE4 hour as proof that Falkenberg or Staffanstorp cannot host a hall. GleSYS already operates in Falkenberg; Microsoft named Staffanstorp in 2021. Neither fact publishes the next plot’s spare megawatts, and neither fact is cancelled by an hourly print.

The third is to treat the 2026–2027 review as if the map had already changed. The fourth is to treat the official area name “Stockholm” as if it named AWS’s unpublished municipality or every hall in SE3, including Falun. The fifth is to add EcoDataCenter’s dated Falun megawatt sentences into an “SE3 capacity” total. Bidding areas do not sum operator campuses.

What to ask next

Ask which bidding area the property sits in, using the official map, and write the area code on the file. Ask which hourly series you are actually using for a cost scenario, and for which period. Ask the network owner the connection questions in the grid-connection note — those answers will not come from Energimarknadsinspektionen’s area page, whether the plot is in Boden or Staffanstorp.

Ask whether anyone in the pack is treating the May 2026 assignment as a completed redesign. If they are, ask for the statute that changed SE1–SE4. Until 29 January 2027, and until any later legal step, the honest label is that the review is open. Then open the electricity-cost note for the rest of the bill stack.

• Which official area contains this municipality?
• Which period and which hourly series sit in the price scenario?
• Has any statute changed SE1–SE4 since the April 2025 EU review?
• What written connection position exists besides the area map?

What this does and does not prove

This note proves that SE1–SE4 are wholesale bidding areas named Luleå, Sundsvall, Stockholm and Malmö, and that they exist so transmission constraints appear in price. It proves that Luleå and Boden, Gävle and Sandviken, Stockholm and Falun, Staffanstorp and Falkenberg seat in those areas as geography, not as allocated megawatts. It proves that a government assignment of 29 May 2026, due 29 January 2027, is open work, and that an April 2025 EU-wide review did not propose changing Sweden’s four areas.

It does not prove spare capacity at any plot. It does not prove next year’s invoice. It does not prove that the area map will change, and it does not prove that the area map will stay. It does not convert operator openings — Meta in Luleå, Microsoft in Gävle, Sandviken and Staffanstorp, AWS Europe (Stockholm) — into an area-level megawatt census. Those remain operator rows with their own wording.
