Sollentuna

Sollentuna is the municipality north of Stockholm where Conapto runs Stockholm 3 North. Conapto’s data sheet states five server rooms with a total of 6 MW, renewable electricity from Vattenfall and heat recovery into Sollentuna Energi & Miljö’s district-heating network.

One operator file is documented here: Conapto Stockholm 3 North. The 6 MW on its data sheet is not defined as IT or facility power, so it is not added to Stockholm-city figures or to Conapto’s south campus.

The heat-recovery sentence names Sollentuna Energi & Miljö as the district-heating counterpart. A described integration is not a delivered megawatt-hour figure, and none is published here.

Sollentuna lies in electricity area SE3, like Stockholm. The area label does not allocate spare grid capacity to any plot; the local network owner’s written position does.

  • Is heat delivery to Sollentuna Energi & Miljö contracted and metered?
  • Which detaljplan covers the building?
