Green Computing Redefined

Connect to the world from Stockholm. With a market of more than 350 million people within a roundtrip delay of 30 milliseconds, covering all major cities of Northern Europe, the Baltic states and western Russia, Stockholm has the prerequisites to become a major hub for green data centers.

In Scandinavia, the colocation market is highly concentrated around the Stockholm area. There are many reasons why. Stockholm is the main business and finance center in the Nordics and the majority of Global 2000 companies present in the Nordics have their regional headquarters in Stockholm.

Our vision is a data center industry where no heat is wasted. We see data center excess heat as a valuable resource that can be part of fighting climate change. The City’s objective is to be entirely fossil fuel free by 2040, and we invite data centers to play a key role in this transition.

 

Why Stockholm?

Stockholm’s competitive advantage rests on its long tradition of technological innovation. Known as Europe’s “unicorn factory,” Stockholm has more $1 billion-plus companies per capita than anywhere outside of Silicon Valley with companies like Skype, Spotify, Klarna, King, Mojang and iZettle. Stockholm’s tech scene has developed over decades into what today is a world-class, mature startup hub. In summary, Stockholm has one of the best ecosystems in the world and one of Europe’s most important tech communities.

The Stockholm region was declared the ‘most competitive’ in the European Regional Competitiveness Index 2019, where it outperformed 267 other regions across the EU. Stockholm was the only region to score a perfect 100 on the index and was praised for its strength in health, human capital and innovation. Stockholm was also declared the world’s smartest city in 2019.

Stockholm is aiming to become a world leader in developing, commercializing and applying new energy and environmental technology. The reputation as a green and innovative city attracts young talents from around the world.

Thanks to the unique dark fiber network already in place, connectivity within Stockholm is exceptionally easy and accessible.

  • Tailor made renewable electricity contracts
  • Dark fiber at the premises
  • Dedicated support through build process

Unparalleled sustainability

Combining low electricity CO2 content with waste heat recovery, you can now build a truly green data center. In Stockholm Data Parks, your data center can even become climate positive thanks to heat recovery.

We believe that green data centers of the future will source sustainable electricity to minimize their environmental impact. In this transition, Stockholm Exergi is making the same commitment, adding renewable capacity to the system for its electricity use in Stockholm Data Parks. With heat recovery, fuel resources used for incineration can be conserved and CO2 emission reduced.

With a data center load of 10 MW, around 20 000 modern residential apartments (55 kWh/m2 per year) could be heated.

During the Spring of 2020, Stockholm Exergi closed the last coal-fired heat production in Sweden. The shutdown has been enabled by a range of measures including the launch of Open District Heating and Stockholm Data Parks to promote large-scale heat recovery.

With the coal plant closed, heat recovery continues to be an essential part of Stockholm Exergi’s strategy for a sustainable future. First, already existing and planned data centers with heat recovery make up an essential part of the heat production capacity that made the closure of the coal plant feasible.

Moving forward, future heat recovery projects will accelerate the transition towards net-zero emissions in multiple ways. Heat recovery will:

  • Free up biofuels currently used by Stockholm Exergi, thereby helping replace usage of fossil fuels on other markets
  • Allow Stockholm Exergi to produce more renewable electricity in its Combined Heat and Power plants, since less heat has to be produced in these plants
  • Reduce the operational hours of less efficient heat pumps in Stockholm Exergi’s heat production portfolio
  • Reduce the need to build new or upgrade existing heat production plants, thereby avoiding emissions during the construction phase

Low cost electricity

Following recent change in electricity taxation for data centers, Sweden now has the lowest electricity prices anywhere in the EU.

Large-scale heat recovery

We recover your excess heat and reuse it to keep the citizens of Stockholm warm.

Stockholm is ideally suited for heat recovery. Many heat recovery projects performed elsewhere do not meet the prerequisites for successful heat recovery. The first challenge is the sheer quantities of heat that need to be handled. A 10 MW data center load corresponds to the heating need of around 20 000 modern residential apartments. Thus, the possibility to fully reuse heat locally, or in the same building as the data center, is not feasible.

The other critical factor to consider is the risk related to the data center relying on a single building or limited residential area for absorbing data center heat.

Only if the data center is connected to a vast network of buildings can heat recovery be performed on a large scale at reasonable risk. With Stockholm’s 12 TWh/year district heating system, sufficient heat demand exists to accommodate heat recovery from data centers of any size (corresponding to 150 data centers with a load of 10 MW).

Stockholm Exergi has more than 25 years’ experience of recovering heat from data centers.

Prepared power

For all sites made available in Stockholm Data Parks, sufficient power is either available or already planned for. This to ensure shortest possible time to market for the investor of the data center.

Redundant power supply can be provided to all sites and means that all loads can be restored if any single component fails. Ellevio’s distribution network has more than 99.98% in historical availability.

Green electricity

Run your data center on renewable electricity. We offer you long-term contracts with tailor-made risk profiles. We help you to build a portfolio with the right level of hedging, and where you can purchase guarantees of origin to determine your mix of renewable electricity. Should you wish to match your electricity need by adding renewable capacity to the system, we will develop a solution based on your specific preferences.

Ready to connect

With the world´s largest open fiber network we connect all sites with dark fiber cables. We connect the site with a cable then supply the market with pairs of fiber to lease. Our network is open for all players on equal terms and Stokab is obliged to lease to all stakeholders who wish to gain access.

We look forward to hear from you! Find out more
