Summary
- YIT’s approximately €300m contract covers a new data centre building at atNorth’s FIN04 campus in Kouvola.
- The design-and-build scope includes civil, structural, architectural, MEP, and commissioning work.
- Construction starts immediately, with completion expected by the end of 2027.
YIT has secured an approximately €300 million contract to design and construct a new data centre building at atNorth’s FIN04 campus in Kouvola, Finland.
The Finnish contractor’s remit covers design, civil, structural, and architectural work, alongside the mechanical, electrical, and plumbing systems and the building’s final commissioning. Construction is beginning immediately, while completion is scheduled for the end of 2027.
YIT will record the contract in its third-quarter order book, turning part of atNorth’s proposed 430MW campus from a development programme into a defined construction package with an agreed value and delivery scope.
MEP delivery carries the programme
Although the contract value is substantial, neither company has disclosed the IT load attached to the individual building. The 430MW figure applies to the planned campus as a whole, rather than the facility covered by YIT’s contract, and the eventual capacity will depend on how atNorth phases its substations, data halls, and customer deployments.
YIT’s responsibility for MEP systems places the contractor across the interfaces most likely to govern the programme. Electrical distribution, cooling plant, controls, fire protection, security, and tenant equipment must be coordinated with the structure before installation begins, while the completed systems will have to operate together under full load, component failure, maintenance, and emergency conditions.
Commissioning extends beyond confirming that individual pieces of equipment switch on. Integrated systems testing will need to show that generators, UPS equipment, switchgear, cooling systems, controls, alarms, and networked building systems respond correctly when normal power is lost or plant is taken out of service.
As rack densities rise, designs agreed early in the construction programme can be overtaken by the hardware eventually installed. A building completed in late 2027 may receive servers with materially different electrical and thermal requirements from those available when its principal plant was specified, forcing the design team to retain enough flexibility without oversizing every system.
Long-lead electrical equipment will exert its own pressure on the schedule. Transformers, high-voltage switchgear, generators, busway, UPS systems, chillers, and heat-rejection equipment all compete for manufacturing slots, while changes to one package can alter cable routes, equipment-room layouts, structural loads, and commissioning plans elsewhere in the building.
Heat reuse moves into the site design
atNorth says FIN04 will operate on renewable electricity and will be capable of supplying recovered heat to the local district-heating network. Finland offers a practical environment for heat reuse because district-heating infrastructure is already widely established, although a technically recoverable source still needs a connection, suitable temperatures, commercial terms, and an offtaker.
Heat pumps may be required to raise the temperature of the data centre’s cooling-water return before it can enter the local network. Those systems add capital cost and electrical demand, while the commercial arrangement has to allocate responsibility for pumping, metering, maintenance, availability, and periods when the network cannot accept the available heat.
A campus developed in stages can also produce an uneven heat profile. Early buildings may operate below their design loads while customers install hardware, leaving less heat available than a district-heating project expects, whereas later phases could produce more than the network can absorb during warmer months.
Finland continues to attract projects through its renewable generation, cooler climate, industrial land, and district-heating systems, yet the market is becoming less forgiving of headline campus figures without matching evidence on power delivery. Grid connections, substations, skilled labour, environmental permits, and specialist equipment now determine how quickly announced megawatts become usable capacity.
The YIT contract provides a clearer delivery marker than a land purchase or early planning statement. Its progress can be measured against a defined completion date, a disclosed construction value, and a scope that runs through to commissioning, while the remaining questions sit around the building’s capacity, customer programme, power phasing, and heat-offtake arrangements.
