Stockholm

Which Stockholm district is actually in the file, and which megawatt sentences share a definition? The municipality covers inner-city halls and several districts used in this register: Kista, Akalla, Västberga, Sköndal, Mariehäll and a south campus. Districts are not interchangeable for fiber or power. Stockholm Data Parks names the City, Stockholm Exergi, Ellevio and Stokab as an invitation to recover heat. Prepared or described heat is not delivered heat. Residual grid capacity is not inferred from the cluster.

Read district by district, not as one hall. Kista holds atNorth SWE01 and Digital Realty’s Kista buildings. Akalla holds SWE02 as a development with a fourth-quarter 2027 target live date and Digital Realty STO6. Sköndal holds Equinix SK2. Mariehäll / Bromma holds Equinix SK1. Västberga holds GleSYS Stockholm. Södermalm holds Bahnhof Pionen; Lugnet holds Bahnhof Thule. The south campus holds Conapto Stockholm 2 South and 4 South. STACK STO01 is pinned at municipality level because the extract used here does not publish a district. Arlandastad is not in this municipality; it is Sigtuna. AWS is not pinned.

Stockholm Data Parks is the municipal-and-utility pattern: green electricity language, excess-heat-as-resource language, and named partners. atNorth SWE01 describes capturing heat outputs and recycling residual heat through the district-heating plant with Stockholm Exergi. Conapto’s 5 September 2024 opening release states heat recovery to Stockholm Exergi in related materials. Those are operator sentences. This register does not publish a Stockholm delivered-heat megawatt-hour figure. GleSYS’s 2020 Falkenberg start remains the dated delivery-start contrast on the west coast.

Megawatt hygiene in this municipality is mandatory. SWE01: 12 MW site power capacity, designed, operator-stated; occupied IT load unknown. SWE02: 30 MW site power announced 29 January 2026 and restated on the SWE02 page; not treated as live IT load. Equinix SK1 and SK2: no retail megawatt on the cited pages. Digital Realty: 22.7k m² colocation space, campus megawatts not on that page. STACK: 18 MW on a market page, definition unclear. Bahnhof: megawatts not disclosed. Conapto: 24 MW campus in the 2024 release; 4 MW on the Stockholm 2 South sheet, not added. GleSYS Stockholm: megawatts not disclosed. Do not sum those rows.

Mechanisms still apply inside the city. Ellevio is named on the Data Parks page as grid operator; that is a counterpart name, not a reserved import. Stokab is dark fiber, not power. A detaljplan and a bygglov still sit with the City. SE3 still does not allocate spare megawatts to Kista or Sköndal. Svenska kraftnät’s indicative map still does not show the underlying network.

Common misreads: treating every Stockholm operator as if it sat in Kista; adding 24 MW and 4 MW; treating SWE02 as operational; treating Data Parks copy as a heat contract; treating 12 MW or 18 MW as grid agreements; pinning AWS; folding Arlandastad into this municipality; treating meet-me-room richness as residual power.

Ask which district and which meet-me rooms are actually used. Ask whether heat reuse is contracted with Stockholm Exergi or only described as a capability. Ask which megawatt figures on operator pages share a definition. Ask which network-owner paper exists for the plot. Ask which detaljplan covers the building, not the cluster slogan.

This municipality brief proves that Stockholm contains the densest reviewed colocation set in this register, with mixed evidence quality and a heat-recovery invitation pattern. It does not prove a municipal megawatt total, does not prove delivered heat, and does not invent districts or halls outside the reviewed set.

Questions for a concrete establishment

• Which district and which meet-me rooms are actually used?
• Is heat reuse contracted with Stockholm Exergi or only described as a capability?
• Which MW figures on operator pages share a definition?
• Is SWE02 being treated as operational before a commissioning source?
• Are 24 MW and 4 MW being added, or kept as campus versus phase rows?
• Which detaljplan and which network owner cover the specific building?
