Sollefteå

Is Hamre Industrial Park in Långsele a commissioned atNorth campus, or a 300 MW plan? Sollefteå is the municipality named by atNorth for SWE04. On 23 February 2026 atNorth confirmed plans to develop a 300 MW data center on a 50-hectare plot at Hamre, expected operational in H1 2028. That figure is announced or planned site power. It is not live IT load. The 2 September 2026 ownership notice does not convert the plan into energised load.

Read the atNorth Sweden pages first for the hectare figure, the Långsele / Hamre wording and the “under development” stage. Read the 2026 acquisition notice second as ownership, not as a construction milestone. Read SWE01 and SWE02 only to keep their Stockholm facts out of this file. Read SE2 third. Then ask Sollefteå municipality which planning documents cover Hamre Industrial Park.

Fifty hectares is land control or site description. A detaljplan, a bygglov and a startbesked are still municipal papers. A connection answer is still a network-owner paper. Transmission-level dialogue, if it exists, is still not the indicative map. Local heat investigations, if they exist, must be cited from a municipal or utility document. They are not invented from Stockholm Data Parks copy.

What the sources show: a named mega-site, a 50-hectare plot, Hamre / Långsele wording, and a 23 February 2026 notice of plans to develop a 300 MW data center, expected operational in H1 2028. What they do not show: live IT load, a reviewed detaljplan extract behind “fully zoned”, or a numbered connection agreement. The 2 September 2026 ownership notice does not change that metric.

Common misreads: reading hectares as IT load; assigning a directory megawatt; treating Equinix ownership as an operating IBX in Sollefteå; adding 12 MW from SWE01; treating site control as Q-status for construction; treating SE2 as reserved northern power.

Ask what public megawatt, if any, the operator has stated on the Sweden site pages. Ask which planning documents Sollefteå has published. Ask whether construction stage is documented or only site control. Ask what grid dialogue is public. Ask which environmental or heat investigations exist and who signed them.

SE2 is not shared with Gävle and Sandviken, which sit in SE3, and those Microsoft locations are not merged into Hamre. Norrbotten’s Meta campus and Boden company record sit in SE1. Stockholm metro sites stay in Stockholm. The only public numbers in this municipality file are 50 hectares and about 490 kilometres north of Stockholm. Those are land and distance. They are not megawatts and they are not an energization date.

The 300 MW sentence is now a dated announced row. It still is not live IT load. If atNorth later publishes commissioning or a numbered connection paper, add that paper with a date. A directory figure that differs from the 23 February 2026 wording stays outside the file.

A due-diligence memo should therefore hold the hectare sentence, the Hamre and Långsele wording, the under-development stage, the 2 September 2026 ownership notice, the municipal plan question and the network-owner question. Fifty hectares is land. Equinix as an owner name is ownership. Neither sentence is a megawatt. SWE01 figures stay in Stockholm. Local heat or environmental investigations, if they exist, must be cited from a Sollefteå or utility document rather than inferred from Stockholm Data Parks copy.

Update 4 November 2026: Enersense said on 3 November that E.ON Energidistribution has contracted it to build two new 130 kV overhead lines, each about 2.5 kilometres, between the Hamre and Nässe substations, with 35 new steel lattice towers. Enersense links the lines to atNorth's planned campus at Hamre. Work starts in November 2026 and is due to be completed in March 2029. In May 2026 E.ON said it had signed a 200 MW connection agreement with atNorth and gave autumn 2028 as the expected commissioning of the facility.

Update 5 November 2026: atNorth and Calentix said on 4 November that they have signed a project development agreement under which Calentix develops heat recovery from SWE04 to the Långsele district heating network, about 2 kilometres from the site; a possible second phase could supply the Sollefteå network about 10 kilometres away. Both networks are operated by Adven. Calentix gives 1.6 MW in the first phase with potential for about 20 MW, says a feasibility study completed in April 2026 found no regulatory or environmental obstacles, and targets a heat purchase agreement in 2027 and first heat delivery in the second quarter of 2029.

This municipality brief proves that Sollefteå has a named atNorth development with a hectare figure and an ownership notice. It does not prove megawatts, commissioning, or a second Sollefteå project.

Questions for a concrete establishment

• What public MW, if any, has the operator stated on the Sweden site pages?
• Which planning documents has Sollefteå published?
• Is Q-status for construction documented or only site control?
• What grid dialogue is public, as opposed to site marketing?
• Did the 2 September 2026 notice change stage or capacity in the text used here?
• Are SWE01 figures being added into this municipality?
