EcoDataCenter annual report: Falun C and D commissioned, 41 MW stated

EcoDC Holding’s 2025 annual report is the dated source for Falun C and D being commissioned and for the reported move from 29 MW to 41 MW as of the balance-sheet date. It also separates future E/F expectations from an 80 MW available-power statement.

EcoDC Holding’s 2025 annual report is the dated source behind the Falun update in this register. In the English extract used here, the company says data centers C and D were fully completed and commissioned and that total capacity at the Falun site increased from 29 MW to 41 MW as of the balance-sheet date.

That is a meaningful project-stage observation: two buildings are described as commissioned, and the report gives a dated capacity sentence. It is still not a complete measurement definition. The extracted wording does not tell the reader whether the 41 MW is IT load, facility load or another boundary. The register preserves the wording rather than converting it.

The report also says construction of E and F began in 2025. It expected F to be operational in the third quarter of 2026 and E at the end of the fourth quarter of 2026, after which the site would amount to 65 MW. Those are company expectations recorded in the report, not certificates that the later buildings were commissioned.

The 65 MW sentence must therefore remain separate from 41 MW. It is a future campus total if the stated E/F sequence enters operation, not an extra 24 MW to add to the commissioned figure. A later source would need to document the actual stage and retain the same metric boundary before the register changes the observation.

Falun’s operator site separately states 80 MW of total available power. That wording describes an available-power envelope and is not the same observation as commissioned C/D capacity or the report’s future E/F sentence. It is stored as a separate row and is not added to 41 MW or 65 MW.

The annual report also mentions EcoDC Borlänge AB working on a new facility and says work in Östersund was discontinued in autumn 2025. The Borlänge entry is therefore a development note connected to the Mistral/EcoDataCenter project record, not evidence of a commissioned hall or a published MW figure. Östersund is not presented as an active project in this register.

For an investor, the next question is not “what is Falun’s one true MW total?” It is which building is operating, which phase is a target, what boundary each figure uses and which written grid or commissioning evidence supports the current state. Ask for the source version, balance-sheet date, phase definition and any later operational update.

The useful reading order is annual report first, project page second and register status third. That order keeps a dated financial disclosure, an operator availability claim and an editorial stage label from being blended into one headline.

The balance-sheet date is important to the reading. A report published after a financial year can describe the position at that year-end, while a project page can describe a later availability statement. Those documents do not have the same as-of date. The 41 MW sentence is therefore a dated observation about the report’s stated position, not a live meter reading for the day a reader opens this article.

The move from 29 MW to 41 MW also needs to stay attached to the wording about C and D. It tells the reader that the company described a change in the Falun site’s capacity after those buildings were fully completed and commissioned. It does not identify the electrical boundary or prove that every part of the 41 MW was occupied by customers. The useful question is not whether the number sounds large; it is what the report means by capacity and which phase it covers.

The E and F statement has a different evidentiary status. The report says construction began in 2025 and gives expected operating periods in 2026. An expectation can guide a project conversation, but it does not close the event until a later source describes what actually happened. If one building enters operation before the other, a later update should preserve that asymmetry rather than promoting both to one campus status.

The 80 MW wording on the operator site is a third observation. “Available power” can be commercially important, but the page does not make it the same thing as commissioned C/D capacity or the future E/F total. The three rows can sit in one project profile because they describe the same campus from different angles; they cannot be arithmetically combined without a shared definition, date and scope.

The report’s references to Borlänge and Östersund reinforce the need for identity and stage control. Borlänge is described as a new-facility development connected to the broader EcoDataCenter story. Östersund is described as discontinued in autumn 2025. Neither statement changes the Falun 41 MW row. A project database should connect related records without turning a development company’s portfolio into one operating campus.

A decision-maker reading Falun should leave with four requests: the exact capacity definition, the building or phase boundary, the later evidence for E/F and the current relationship between available power and the network or facility load. If those documents are not public, the correct conclusion is not that Falun has no capacity. It is that the public file supports a dated commissioned observation, a separate future expectation and a separate availability claim.

A later source should be explicit about whether it is updating the report’s balance-sheet observation, the operator’s availability statement or the E/F forecast. “Falun has 65 MW” would be incomplete without saying whether it describes commissioned phases, a future campus total or a commercial envelope. The article’s value is to make that missing qualifier visible before a number enters a market comparison.

The report should therefore be cited with its publication date and balance-sheet context whenever the 41 MW figure is reused. If the source is later replaced, the old figure should remain in the history with its original wording. That preserves the difference between a historical observation and a current status while still allowing the project profile to show the latest supported row.

Why it matters

Falun shows why a dated project row is more useful than a headline total: commissioned buildings, future phases and available power can coexist without being additive.

What remains unknown

The extracted report wording does not define 41 MW as IT or facility load, and the cited material does not verify the later E/F target as a completed operating phase.
