Gävleborg County

What is actually public in Gävleborg beyond two municipality names in a 2021 cloud-region opening? The county contains Gävle and Sandviken, two of the three municipalities Microsoft named when it opened the Sweden datacenter region on 16 November 2021. Facility megawatts are not published in the cited Microsoft materials. The third named municipality, Staffanstorp, sits in Skåne and in SE4. Treat the three sites as related cloud-region locations, not as one campus and not as a Gävleborg megawatt total. Since October 2026 the register also holds a data-centre building permit at Vallhalla west of Lingbo in Ockelbo, and EcoDataCenter's planned data centre at Norrsundet in Gävle, which is under environmental consultation.

Read the 16 November 2021 Microsoft opening text first. It names Gävle, Sandviken and Staffanstorp and describes Azure and Microsoft 365 as available. Then read the later community PDF as a company community document, not as a capacity disclosure. Then open the two municipality files so that Gävle and Sandviken stay separate plots. Then place each site by its local network: Nätområden.se puts the Gävle and Sandviken networks in SE3 and the Ockelbo and Hälsingland networks in SE2, so the county spans two bidding areas. Staffanstorp leaves this county file at that point; it belongs to Skåne.

A Microsoft region opening is not a municipal permit file and not a network-owner agreement. The cited materials do not name the network owner for each municipality. They do not publish a street-level plot. Boverket’s detaljplan guidance still applies if a reader wants to know what the municipality has actually adopted for a property. Svenska kraftnät’s indicative map, if consulted, remains a transmission-level indication for 2026 and does not show underlying-network capacity in Gävle or Sandviken.

What the named sources show is narrow and should stay narrow. Microsoft opened a Sweden datacenter region on a dated day and named three municipalities. Capacity remains undisclosed. Construction-job or community-investment figures that appear in company PDFs are company estimates. They are not an operating-staff census and not a megawatt series. No later primary Microsoft stage-change notice for these two municipalities is used in this register.

Common misreads are to treat “Sweden region” as a single Gävleborg campus, to assign a directory megawatt to Gävle or Sandviken, to add the two municipalities into one load, or to read a bidding area as spare power. Another misread is to import Staffanstorp’s SE4 price story into this county. A further misread is to treat community-investment language as proof of a measured local effect.

Ask which local planning or environmental documents name a site in Gävle and which name a site in Sandviken. Ask which network owner covers each municipality. Ask whether later PDFs describe operations or construction. Ask what is known about backup-fuel arrangements beyond the 2021 launch text. If the answer is that those facts are not in the cited pages, record the gap.

Mechanisms around Gävle and Sandviken stay ordinary even though the operator is a hyperscaler. A detaljplan is still a municipal instrument. A connection answer is still a network-owner paper. A bidding area still shows transmission constraints in the wholesale price and still does not reserve import on a cadastral unit. Svenska kraftnät’s indicative map, if opened, still does not show the underlying network. Community-investment language in a company PDF is still a company estimate, not a measured traffic, noise or employment series.

What this file refuses to do is as important as what it records. It refuses a directory megawatt. It refuses a merged Gävleborg campus. It refuses to treat the November 2021 opening as a 2026 stage-change notice. It refuses to relocate Staffanstorp. Readers who need a decision should leave with two municipal questions and two network-owner names, not with a county total.

Update 28 October 2026: in a press release, grid company Ellevio said it has signed connection agreements for data centres of around 400–500 MW in total and that Gävleborg accounts for the largest share of its active data-centre cases. The release gives no county split, no customer and no site, so no megawatt figure is assigned to Gävleborg or to any hall in this register.

Update 2 November 2026: on 16 October 2026 Västra Gästriklands samhällsbyggnadsförvaltning granted a building permit for a data centre with offices, switchgear and a transformer station on Vallhalla 1:125 (Fallåsvägen 51) in Ockelbo, case VGS-BYGG 2026-000365, and on 23 October a permit for a transformer station on the same property. The notices do not name the applicant. The plan description for the Vallhalla industrial area says a plan agreement was signed with Hyperco Oy, Sverige filial, and that Ellevio's Grönviken switching station is intended to supply the area. No megawatt figure is published.

Update 10 November 2026: EcoDataCenter states that it intends to apply for a permit under the Environmental Code for a data centre at Norrsundet in Gävle municipality and has consulted under chapter 6 of the Code, with comments requested by 11 October 2026. SMHI published its response to the scoping and Seveso consultation on 30 October 2026 (case 2026/2149/6.3.1). The consultation document has not been reviewed here and no megawatt figure is recorded.

This county brief proves that Gävleborg contains two of three named Microsoft Sweden-region municipalities and that facility megawatts are not in the cited sources. It does not prove a county capacity, does not invent a third Gävleborg hall, and does not move Staffanstorp out of SE4.

Questions for a concrete establishment

• What is publicly documented beyond municipality names and cloud-region availability?
• How should construction-job figures in community PDFs be separated from operating staff?
• Which network owner covers each named municipality?
• Which local planning or environmental documents, if any, identify the Gävle plot and the Sandviken plot?
• Has Microsoft published a later stage change for either municipality after November 2021?
• Are Gävle and Sandviken being kept as two files, or merged into one Gävleborg campus?
