ByggPartner’s 12 May 2025 MFN notice is Hall E in Falun, not a megawatt figureOn 12 May 2025 ByggPartner i Dalarna said it had a collaboration assignment to build a new wooden data hall — Hall E — for EcoDataCenter at Västermalm in Falun, valued at about SEK 300 million, ready in December 2026. The MFN notice does not state a megawatt.

Stockholm’s Akalla page is a heat-and-lease site file, not Barings’ 30 MWStockholm’s living Akalla project page records tomträtt to atNorth on Akalla 4:8 and to Ellevio on Akalla 4:7, with both construction starts in 2026. A dated Ellevio answer on 13 March 2026 says capacity in this part of Stockholm is good. Heat recovery next to Akallaverket is not a metered offtake and not Vanda 3.

Borlänge’s 24 September 2025 Hushagen paper is a SEK 200 million LOI, not 250 MWOn 24 September 2025 Borlänge said Fastighet AB Hushagen had signed a letter of intent to sell further Kvarnsveden industrial land to EcoDataCenter, with a bid of SEK 200 million. The same paper keeps land by the district-heat plant in municipal hands and names SEK 100 million of Borlänge Energi grid services over 20 years. An LOI is not a completed sale and not the groundbreaking access figures.

Conapto’s 5 December 2024 paper is an OCP Ready liquid-cooling stamp, not a new hall megawattOn 5 December 2024 Conapto said Stockholm 4 South had become the first data-centre in Europe to earn OCP Ready V2 for Hyperscale. The same notice says the certified hall is uniquely positioned to support high-density liquid-cooled workloads. A checklist stamp is not the later +8 MW or 28 MW papers.

atNorth’s 6 September 2023 SWE01 paper is a heat-recovery cooling design, not a 2026 megawatt-hourOn 6 September 2023 atNorth said SWE01, launched in 2022, was shortlisted for the Energy Awards in heating and cooling. The notice calls it one of the world’s first +10 MW halls whose primary cooling was designed for heat recovery, capturing 85 percent of the electricity as heat that can heat up to 20,000 homes. Designed and can are not a metered 2026 delivery.

Microsoft’s 26 August 2022 Staffanstorp paper is a withdrawn backup permit, not a new hallOn 26 August 2022 Microsoft Sweden said it had withdrawn its permit application for backup generating sets at the Staffanstorp data centre. The planned backup permit was for a facility of 70 MW supplied power. The company will keep operating and expanding only with the backup sets already on site. Seventy megawatts is a withdrawn permit figure, not IT load, and not the later unnamed Saft battery paper.

Borlänge’s 29 January 2026 Kvarnsveden note is a planbesked, not an adopted planOn 29 January 2026 Borlänge’s environment and planning board gave a positive plan notice for part of Kvarnsveden 3:392 and assigned a detailed plan. The applicant is EcoDC Borlänge AB. The notice lapses if a plan agreement is not signed within five years. A planbesked is not an adopted plan and not a new megawatt.

GleSYS’s 1 October 2020 Falkenberg start is dated heat delivery; 26 GWh stays potentialOn 1 October 2020 GleSYS said it had started supplying district heating to Falkenberg Energi from a newly built west-coast hall. The same release listed 3 MW utility power and said the venture had the potential to heat 1,700 residential buildings and may amount to as much as 26 GWh a year, 25% of Falkenberg’s district heat. Potential is not a measured ledger.

Conapto says Ellevio added 8 MW at Stockholm 4 South; 20-to-28 MW is a 24 October 2025 company sentenceOn 24 October 2025 Conapto said Stockholm 4 South would increase by 8 MW of power from Ellevio, scaling the site from 20 MW to 28 MW, ready from 1 January 2026. That is a company capacity sentence. It does not redefine the 2024 south-campus 24 MW wording already in this register, and it does not publish delivered heat.

DeepL says a liquid-cooled DGX GB200 SuperPOD is operational at EcoDataCenter in SwedenOn 11 June 2025 DeepL said it had deployed an NVIDIA DGX SuperPOD with DGX GB200 systems, the first such deployment in Europe, now operational at partner EcoDataCenter in Sweden. The notice describes a liquid-cooled, rack-scale design. That is a customer-and-cooling occupancy paper. It does not publish a Falun megawatt and does not replace the 2024 CoreWeave Blackwell notice.

Google says it will invest at least €13 billion in Finland in 2027–2028; that is not HorndalOn 9 September 2026 Google announced plans to invest at least €13 billion in Finnish digital infrastructure over 2027–2028, naming Hamina, Kajaani, Muhos and Vaala, plus energy partnerships with Fingrid, Fortum and wind counterparties. The notice is a Finnish investment and siting story. It does not publish a Swedish megawatt and does not update Horndal’s 2026 groundbreaking.

atNorth’s 2 September 2026 notice names four Nordic mega sites; a name is not a live megawattThe same 2 September 2026 ownership notice that closed the CPP Investments and Equinix acquisition also lists four mega sites under development — Kouvola, Ølgod, Sollefteå and Haugaland — plus a Stockholm metro site. That is a naming pass. It does not publish a megawatt figure per plot, and it does not merge Sollefteå with Vertical Data’s later purchase agreement.

Fortum and EcoDataCenter publish a 10 MW Falun PPA; that is not a new IT-load rowOn 22 June 2026 Fortum said it had signed a power-purchase agreement with EcoDataCenter for the Falun data center, where CoreWeave is establishing advanced compute. The contract covers 10 MW in bidding area SE3 between 2026 and 2030, with guarantees of origin from Dalälven hydropower. A PPA envelope is not commissioned IT load and is not added to the 41 MW annual-report sentence.

Sollefteå council approves the Hamre agreement proposal; a vote is not a groundbreakingOn 23 February 2026 Sollefteå Municipality said the municipal council had voted, with a large majority, to approve the agreement proposal with atNorth and that the municipality would proceed with the sale of Hamre land. The notice is a dated council decision. It does not publish megawatts, does not record a building permit, and does not replace the same-day operator campus announcement.

EcoDataCenter reports construction start at Kvarnsveden; 250 MW is access at launch, not a commissioned hallOn 24 September 2025 EcoDataCenter said it had started construction of a mega campus at the former Kvarnsveden paper mill in Borlänge, with the first data center scheduled for completion in early 2027. The same notice says the campus will have access to 250 MW at launch, with potential to scale to 600 MW. Access and potential are not occupied IT load. The later Mistral partnership does not rewrite those figures.

CoreWeave and EcoDataCenter announce a Swedish Blackwell cluster; thousands of GPUs are not a megawattOn 28 August 2024 EcoDataCenter said CoreWeave would host one of Europe’s first large-scale NVIDIA Blackwell clusters in Sweden, using thousands of GPUs, with the clusters set to be operational by early 2025. Falun’s municipal chair is quoted. The notice publishes no megawatt figure. A GPU headline is not a capacity row, and early 2025 is a target.

Falu Energi & Vatten names EcoDC as a pellet-drying heat source; that is not a Stockholm megawatt-hourFalu Energi & Vatten’s pellets page, updated 11 November 2025, says the heat used to dry pellets comes from industrial surplus heat in Borlänge, the Ingarvet combined-heat-and-power plant, and EcoDC. EcoDataCenter’s Falun site page describes surplus energy turned into fuel via the CHP plant. Those are municipal-utility and operator heat sentences. They are not a measured Falun megawatt-hour ledger and not a Stockholm Exergi contract.

Stockholm Exergi describes a 2021 Conapto heat contract; household counts are not measured megawatt-hoursStockholm Exergi’s Open District Heating page, accessed on 12 September 2026, says the first Open District Heating agreement with Conapto was signed in 2021, that heat pumps raise rejected heat from about 30 °C to 70 °C, and that the first facility was enough to heat about 2,500 homes a year. A later Sätra hall, inaugurated in August 2024, has a contract to recover up to 10 MW of heat. Those are utility-described contract and capacity sentences. They are not a public metered ledger.

CoreWeave and Conapto announce a Stockholm colocation agreement; first capacity said to be online at Stockholm 4 SouthOn 24 June 2026 CoreWeave and Conapto said they had signed a colocation agreement covering two Stockholm campuses, with initial capacity already online at Stockholm 4 South. That is a commercial occupancy notice. It does not publish a megawatt figure, redefine the 2024 south-campus capacity sentence, or convert heat-recovery wording into delivered megawatt-hours.

Google reports groundbreaking at Horndal on 2 June 2026; completion targeted for 2028On 2 June 2026 Google said it had broken ground on a data center in Horndal, Avesta Municipality. The company pages used here describe an air-cooled facility designed for off-site heat recovery, about 100 direct jobs and a EUR 5 million community fund. They do not publish a megawatt figure. Construction under way is not commissioning.

Heat-recovery readiness is not delivered heat: Horndal, Hamina and the Swedish fileGoogle’s 2 June 2026 Horndal notices say the new hall is being built ready for off-site heat recovery. The same press page says the Hamina, Finland, project is already supplying about 2,000 households. Those are different evidence states. A Swedish file that copies the Finnish supply sentence onto Horndal invents a delivery that the source did not claim.

Sollefteå reports an E.ON 200 MW connection agreement for atNorth in LångseleOn 28 May 2026 Sollefteå Municipality said E.ON Energidistribution and atNorth had signed a 200 MW electricity-connection agreement for the planned AI facility in Långsele. The municipal notice is a reported distribution-network event. It is not a Svenska kraftnät reservation, not the operator’s 300 MW campus announcement, and not evidence that a hall is energised.

Microsoft says Denmark East is open; a Danish region is not a Swedish capacity updateOn 26 March 2026 Microsoft announced the official opening of Denmark East, with campuses named in Høje Taastrup, Køge and Roskilde. The notice is a Nordic-neighbour region event. It does not restate Microsoft Gävle, Sandviken or Staffanstorp, and it does not publish a Swedish megawatt figure.

atNorth confirms plans for a 300 MW Sollefteå campus; H1 2028 is a target, not operationOn 23 February 2026 atNorth said it planned to develop a 300 MW data center at Hamre Industrial Park in Långsele, Sollefteå Municipality, on a 50-hectare plot called Hamre 1, expected to be operational in the first half of 2028. The notice is an announced site-power and land plan. It is not a construction start, a commissioning certificate or a defined IT-load reading.

Mistral AI and EcoDataCenter announce a €1.2 billion Borlänge partnership; 2027 is a schedule, not a hallOn 11 February 2026 Mistral AI and EcoDataCenter said they would invest €1.2 billion in Swedish digital infrastructure through a partnership to build an AI-focused data center at EcoDataCenter’s Borlänge site, scheduled to open in 2027. The primary notice does not publish a megawatt figure. An investment intention is not commissioning.

Sollefteå says it intends to sign a Hamre development agreement with atNorthOn 5 February 2026 Sollefteå Municipality said it and atNorth had prepared an agreement for a large-scale high-density data center and that the most advantageous location was the already-planned Hamre 1 land. The notice is a municipal intention. It does not by itself prove that the council signed, that construction started, or that megawatts were reserved.

atNorth announces SWE02 in Stockholm: 30 MW metro site, target go-live Q4 2027On 29 January 2026 atNorth said it would build SWE02, a 30 MW metro data center close to SWE01, scheduled to go live in the fourth quarter of 2027 and enabled for heat reuse with Stockholm Exergi. The notice is an announced site-power and design intention. It is not evidence that 30 MW is energised, occupied or delivered as heat.

AWS European Sovereign Cloud is generally available in Brandenburg; Stockholm remains a separate RegionOn 15 January 2026 Amazon said the AWS European Sovereign Cloud was generally available, with its first Region in Brandenburg, Germany, physically and logically separate from other AWS Regions. Planned sovereign Local Zones are named for Belgium, the Netherlands and Portugal. The notice is a sovereignty-product event. It does not open a Swedish sovereign region or add megawatts to Europe (Stockholm).

Microsoft’s 30 April 2025 European commitments: a 40 percent capacity plan is not a Swedish MW rowOn 30 April 2025 Microsoft said it planned to increase European datacenter capacity by 40 percent over the next two years, expanding operations in 16 European countries, and that combined with recent construction the plans would more than double European capacity between 2023 and 2027. The notice does not name a Swedish megawatt figure or a new Swedish campus event.
