Compute and storage on a single grid connection.
Dalsbruk on Kimitooen pairs a battery energy storage system with a managed datacenter behind the same 10 kV connection. The site is designed so that a grid down-regulation signal can be answered with a combination of battery charging and compute-load adjustment, split by state-of-charge and thermal headroom. To the system operator, the site is designed to present as a single responsive asset. To the compute customer, it is infrastructure hosted on a grid where flexibility is a built-in revenue line.
That pairing is the thesis behind the site. Nordic power prices rank among the cheapest green electricity in Europe, Finland hosts one of the continent's deepest balancing-reserve markets, and managed compute workloads — within a defined envelope — can absorb flexibility without impact on tenant operations.
6 MWh installed, 18 MW engineered.
The site is engineered to a nameplate of 18 MW / 18 MWh of Huawei LUNA2000 Smart String ESS. The first 6 MW / 6 MWh are installed and grid-connected. Commissioning is underway. The remaining capacity is engineered and pre-positioned — same switchgear, same cable runs, same layout — ready to be energised as subsequent phases of the Dalsbruk build-out are completed.
The installed capacity is grid-connected and designed and ready for dispatch. The engineered expansion follows in increments as each phase of the build-out is completed.
Why the pairing matters.
A standalone battery is a useful asset. A standalone datacenter is a useful asset. Co-locate them behind the same grid connection and the two cover each other's limitations. The battery is designed to handle fast, short-duration calls. The compute load is designed for slower, longer-duration down-regulation without cycling the battery. The datacenter's thermal profile is engineered for a heat-recovery loop serving the municipality and neighbouring industrial users. Each additional asset on the site is designed to increase the value of the others.
Dalsbruk is the first site where this model is engineered end-to-end. The Nordic grid needs flexibility; the site needs green power; the local district heating network needs winter thermal energy. The site sits at the intersection of all three, designed to serve all three from a single 10 kV connection.
What comes next.
As each phase of the Dalsbruk build-out is completed, incremental capacity arrives as a step on the ramp — not as a new project.
For those evaluating Nordic sites where grid services are a core feature rather than an afterthought, Dalsbruk is the reference case.
