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

Conapto’s 5 September 2024 release says Stockholm 4 South opened and describes a 24 MW south-campus figure. The related 4 MW Stockholm 2 South phase figure is kept separate, and the release is treated as an operator claim rather than an inspection certificate.

On 5 September 2024 Conapto announced that Stockholm 4 South had officially opened. The release said that, together with Stockholm 2 South, the south campus offered 5,200 square metres of computer rooms and 24 MW of power. The opening statement is the dated source for the event in this register.

The 24 MW wording describes a campus-level operator claim. The release does not define the figure as IT load, facility load, contracted import or occupied load. It is therefore useful as a dated observation with a boundary gap, not as a number to compare directly with every other Swedish MW row.

The related Stockholm 2 South data sheet says that phase has five computer rooms with a total capacity of 4 MW. That is a phase-level figure and is stored separately. It is not added on top of the 24 MW south-campus statement because the campus wording may already include the phase.

The operator’s related materials also describe heat recovery toward Stockholm Exergi and renewable-electricity matching through Vattenfall. Those are important sustainability and service claims, but they are not the same evidence as an occupied-load reading or a municipal decision. Keep the commercial relationship, energy procurement description and capacity metric on separate lines.

For a customer or investor, “open” also needs a scope. Ask whether it means the building was physically complete, customer space was available, power was energised, or the operator made the public opening announcement. A press release can establish what the operator said on a date; it does not automatically provide an inspection certificate or the current occupied load.

The next useful documents are the current facility or phase data sheet, the capacity definition, the network or utility position, and any later operating evidence. If the project file needs a sustainability claim, ask for the period and boundary behind heat delivery and renewable matching rather than repeating the headline.

DataCenterSweden records the 5 September 2024 opening as an operator-reported event connected to the Conapto south-campus project. It keeps 24 MW and 4 MW as non-additive rows and does not infer a Swedish total from them. That is the important reading discipline: a phase can sit inside a campus, and an opening statement can coexist with an unknown occupied load.

The article is therefore useful for locating a dated Stockholm colocation milestone, not for answering how much IT capacity is available today. Those are different buyer questions and require different documents.

The opening date and the capacity sentence answer different questions. Conapto’s release is the dated source for what the operator said opened on 5 September 2024. The 24 MW figure is described in the context of the south campus together with Stockholm 2 South. The release does not define whether that figure is IT load, facility load, contracted import or another commercial boundary. The article therefore reports both facts without turning them into a single verified operating metric.

The 4 MW figure in the Stockholm 2 South data sheet has a narrower phase boundary. It can be useful to a reader comparing the individual phase with the campus description, but it cannot be added mechanically to 24 MW. The campus sentence may already include Stockholm 2 South. The data model must therefore preserve phase and campus scope, publication date and wording, even when both sources use the word capacity.

Square metres create a similar risk. The 5,200 square metres of computer rooms is a physical-space statement about the south campus in the release. It does not tell the reader how much of that space is occupied, energised, customer-ready or assigned to one phase. Space, power and occupied IT load are related but not interchangeable. A customer question about available room needs a current facility response, not an arithmetic subtraction from the press figure.

The heat-recovery and renewable-electricity statements are useful service context. They identify commercial or technical relationships that a customer may want to investigate. They do not establish a measured annual heat volume, a municipal permit or a network agreement. A source that says heat is recovered can support that the operator describes a recovery arrangement; it cannot silently become a statement that a defined number of megawatt-hours was delivered.

“Officially opened” should also be kept in quotation with its source. In an operator release it establishes a public opening announcement. It does not necessarily identify the date of physical completion, the date of energization, the date customer space became available or the date an independent inspection closed. Those events may coincide, but the cited material does not prove that they do.

The next evidence request is consequently practical: current phase data sheet, exact capacity definition, scope of the 24 MW campus sentence, relationship between 4 MW and 24 MW, network or utility documentation, and measured operating or heat-delivery evidence for the relevant period. Until those sources are available, the reliable headline is a dated operator-reported opening with non-additive campus and phase observations, not a claim about today’s occupied Stockholm IT capacity.

A later facility update should say whether it updates the campus statement, the Stockholm 2 South phase or a different building. Without that scope, a new number can appear to contradict the release when it actually describes another boundary. The editor should preserve both observations and add a note about comparability rather than choosing the most recent-looking number.

For a customer, the most useful next step is a current answer from the operator for the required room, power and service boundary. For a public register, the useful next step is a dated source that names what opened, what is offered and what is measured. The release supports a public opening event. It does not, on its own, turn a campus headline into a live inventory of occupied IT capacity.

Why it matters

It adds a dated Stockholm colocation opening and shows why a campus figure and a phase figure must remain non-additive.

What remains unknown

The cited material does not define 24 MW as IT or facility load and does not state the current occupied load or a separate grid agreement.
