Cost-effective and emissions-cutting Data Centres in Helsinki

Data Centres in Helsinki in a nutshell

• Electricity produced in Finland is 96% carbon-neutral, giving data centres a low carbon footprint from day one.
• Lowest electricity costs in Europe, with low cooling demand thanks to the Nordic climate.
• 99.9995% main grid transmission reliability — on average just one 30-minute outage per decade.
• Waste heat is a sellable asset: one data centre’s recovered heat can warm up to 20,000 apartments via Helen’s district heating network.
• Zoned, build-ready sites all within a 20 km (12.5 mile) radius of the city centre.
• Finland consistently ranks high in EU digitalisation, with smart grid 2.0 infrastructure and a Europe–Asia subsea cable link (up to 144 Tbit/s, under 20 ms to Central Europe).
• Established ecosystem: Telia, Equinix, and Digita already operate here; Microsoft and Google operate elsewhere in Southern Finland.

Why Helsinki for data centre companies?

Helsinki combines the three things data centre operators care about most: low operating costs, sustainability, and reliability. Electricity is the lowest-priced in Europe, and 96% of electricity produced in Finland is carbon-neutral (Finnish Energy, 2025), so cost savings and emissions reductions arrive together rather than as a trade-off.

The cool Nordic climate keeps cooling energy low year-round, while the same climate creates steady, year-round demand for the waste heat your facility produces — meaning recovered heat becomes revenue rather than a disposal problem. Add a national grid with 99.9995% transmission reliability (Fingrid, 2026), the EU’s most digitally advanced infrastructure, and direct subsea connectivity to Central Europe and onward to Asia, and Helsinki becomes a genuinely rare combination: a place where running a data centre is cheap, clean, and dependable at the same time.

Data centre zoning in Helsinki

The City of Helsinki has actively zoned dedicated sites for new data centre construction, all located within a 20-kilometre (12.5-mile) radius of the city centre. These sites are planned with the infrastructure operators need: available space, power capacity, data connectivity, electricity supply, cooling, and heat recovery connections. Because the zoning is already in place, operators avoid much of the planning uncertainty that slows projects elsewhere. Contact us for site-specific details on available space, power capacity, connectivity, cooling, heat recovery, and commissioning schedules.

Energy savings for data centres in Helsinki

• Lowest electricity prices in the EU and the Nordics, directly reducing your single largest operating cost.
• Low cooling energy use — the Nordic climate allows free-air cooling for much of the year, with backup systems drawing on cool ambient air in colder seasons.
• Waste heat as revenue: recovered heat is a sellable asset, sold into Helsinki’s district heating and cooling networks rather than wasted.
• Emissions reductions at scale: 1 MW of recovered waste heat cuts roughly 1,700 tonnes of CO₂ emissions annually. Helsinki needs about 7 TWh of heat energy each year to warm its homes and properties.
• Low-cost land is widely available across Finland.

Data centres collaborating with Helen

Helen is the energy company owned by the City of Helsinki, with over 100 years of experience in the energy sector and more than 550,000 customers across Finland.

For data centre operators, Helen is the partner that turns waste heat into value: heat recovered from your facility is fed into Helen’s district heating network and used to warm Helsinki. At best, a single data centre can heat more than 20,000 apartments, directly replacing fossil fuels. Helen’s energy production has been recognised as among the most efficient in the world, and the company is working toward 100% carbon-neutral production.

Helen already collaborates with data centre clients including Telia, Equinix, and Digita. There is room in the system for high-value operators who strengthen Helsinki’s competence and business clusters.

Existing data centres and related companies in the region 

Helsinki already hosts an established data centre community. Telia, Equinix, and Digita operate facilities in the Helsinki Metropolitan. Elsewhere in Southern Finland, global operators including Microsoft and Google (the latter since 2011) have established data centres.

A defining feature of the region is the partnership model: these operators sell their waste heat to local energy companies’ district heating and cooling networks, generating revenue while reducing local emissions. For Telia, recovered heat from a single data centre warms around 14,000 two-room apartments through Helen’s district heating network.
