Conapto says Stockholm 4 South is open; south campus stated at 24 MW

A 5 September 2024 Conapto release is the dated opening claim used for Stockholm 4 South.

Conapto said Stockholm 4 South had officially opened and that, together with Stockholm 2 South, the campus offered 5,200 m² of computer rooms and 24 MW of power. Heat recovery to Stockholm Exergi and 100% renewable electricity via Vattenfall 24/7 matching are operator-stated in related materials.

A Stockholm 2 South data sheet states five computer rooms with a total capacity of 4 MW. That phase figure is stored separately and is not added on top of the 24 MW campus figure.

The release is treated as an operator commissioning claim, not as an inspected certificate.

Why it matters

It adds a dated Stockholm colocation campus figure that can be shown with its definition limits.

What remains unknown

IT versus facility definition for 24 MW, and occupied load, are not in the release.
