DigiPlex data center to heat 10,000 Stockholm households

DigiPlex, the leading Nordic data center operator, and Stockholm Exergi, (formerly Fortum Värme), the leading heating and cooling supplier of Stockholm, Sweden, have entered a large-scale heat reuse agreement. The agreement is the world’s first under which an operational data center, with an indirect evaporative air-to-air cooling solution, will be retrofitted to recover excess heat for the local district heating system. The agreement corresponds to heating up to 10,000 modern residential apartments.

“Every time we browse the Internet, stream a TV series or use the cloud, a process starts in a data center. If that data center is a power-hungry, fossil fuel-fired one that releases excess heat into the atmosphere, we as individuals are contributing to climate change. At DigiPlex, we are very proud to lead the industry by using the excess heat from our Stockholm data center to heat thousands of households. Digitization needs to support improved sustainability, and this partnership with Stockholm Exergi is a big leap forward, one that will enable residents’ digital activity to contribute to heating their own homes,” says Gisle M. Eckhoff, DigiPlex CEO.

“The agreement with DigiPlex is a strong validation of our waste heat recovery program and Stockholm Data Parks. The partnership with DigiPlex shows that heat recovery to district heating systems is also compatible with indirect air-cooling technology. It represents a key step towards our vision of using data center heat to build a more sustainable society. As part of our drive to make Stockholm fossil fuel-free, our objective is that 10 percent of Stockholm’s heating needs shall be provided by recovered data center waste heat,” says Anders Egelrud, Stockholm Exergi CEO.

Close to ninety percent of all buildings in Stockholm are connected to the district heating network. The Swedish capital is one of the few cities in the world where large-scale heat reuse from major data centers is possible.

“Digitalization must go hand in hand with the development of environmental technology. With Stockholm being in the absolute forefront of both fields this is a natural step for the city. Utilizing smart technological solutions to make the most of synergies between recovered data center heat and the city’s heating needs is a part of the environmental objective to become fossil fuel-free by 2040. I am determined to make Stockholm a major hub for sustainable data centers,” says Karin Wanngård, Mayor of the City of Stockholm.

10 biggest Stockholm tech startup stories of 2017

“Another year has passed and while we thought 2016 couldn’t be topped, 2017 has been chock-full of tech success stories. Stockholm’s tech scene has experienced yet another year of extraordinary growth and innovation. ”

Read more about the impact Stockholm Data Parks have on the city of Stockholm. We are at second place!


“The region has once again cemented its position as a worldwide tech leader with the emergence of more unicorns, the establishment of more international companies, and continued ingenuity within the sector.

It would be hard to gather the city’s many successes into a single article, so here are the top 10 hand-picked tech stories and developments to come out of Stockholm in 2017.

1. Stockholm: the ‘impact’ unicorn factory

Stockholm’s startup ecosystem is one of the best in the world (see point 7 below), so it’s no surprise that so many Stockholm-based companies have reached unicorn status.

A big part of that success, however, is Stockholm’s “pay-it-forward” ethos, whereby successful founders give back to the startup community.

This approach is perhaps best exemplified by Niklas Adalberth, co-founder of billion-dollar Swedish company Klarna, and his launch of the Norrsken Foundation, a new kind of impact investment fund that backs entrepreneurs using technology to solve the world’s most pressing challenges.

By the end of 2017, Stockholm’s Norrsken House – “Europe’s biggest hub for impact and technology” – was home to more than 120 companies that Adelberth reckons will define a new class of ‘unicorn’.

“Instead of getting a company to the valuation of a billion, we want it to positively influence one billion people. An impact unicorn,”he recently told TechCrunch.

2. Stockholmers bask in warmth of nearby data parks

The tech scene in Stockholm has been heating up, in every sense of the word.

As more data centers are established in the region, the intensive heat they generate is rapidly increasing too.

So as not to waste the surplus of heat, Stockholm has collaborated with infrastructure companies Fortum Värme, Ellevio, and Stokab to form Stockholm Data Parks. The project recovers heat that will then be used to supply 10 percent of the city’s residential heating demand, supporting the city’s objective to be fossil fuel free by 2040.

3. Stockholm gaming scene FTW

Stockholm’s gaming industry has long been one of the most competitive in the field and its success streak continued into 2017.

According to the Game Developer Index 2017, there are currently 2,596 game developers employed by 123 companies in the greater Stockholm region. Ranging from gaming giants including King, Mojang, and Paradox Interactive to smaller indie studios like Lionbite Games and Fatshark, the city is a veritable hub of gaming activity.

2017 was also the year that award-winning Stockholm-based developer EA DICE turned 25, while its best-known gameBattlefieldturned 15. With that kind of longevity for studios in the city, it’s little wonder Assassin’s Creeddeveloper Ubisoft decided to launch a 100-person development studio in Stockholm in August.

4. Stockholm named Europe’s second-best performing city

Sweden frequently appears at the top or near in global rankings for, well, almost everything.

The City of Stockholm is also no stranger to the top of various lists. And in December 2017, its booming tech community and advanced manufacturing sector earned it the title second best performing city in Europe by the Milken Institute, an independent economic think tank based in Santa Monica, California.

The accolade acknowledges the opportunities for prosperity within the city, measuring economic performance using “outcomes-based metrics including job creation, wage gains, manufacturing, and skilled service industry concentration.”

5. Feel the thunder: Stockholm IPO and exit boom rolls on

Stockholm’s stock exchanges were once again buzzing with new listings in 2017, continuing a trend from 2016.

According to year-end figures from Nasdaq, there were 96 new listings on Stockholm’s main market and the alternative First North market in 2017, including 71 IPOs.

Indeed, First North dominated Stockholm’s IPO scene, accounting for 80 percent of the total number of IPOs, proving it’s “a great platform” according to Adam Kostyál, Nasdaq’s Head of European Listings.

“Entrepreneurial companies can enter, mature, gain some experience and then take the next step,” he told Bloomberg.

There has also been exciting talk of Stockholm-based unicorn Spotify going public with a valuation of $20 billion, according to investment bank GP Bullhound.

6. Stockholm cruises toward Europe’s first 5G rollout

In September, Ericsson, Telia, and Intel deployed the first public 5G live network in Europe amid final preparations to launch 5G in Stockholm in 2018.

The fifth generation (5G) wireless connection has been built to keep up with increasing demand of devices that need a mobile internet connection, and will ensure speedy internet services.

Telia Company’s Global Head of Networks, Gabriela Styf Sjöman explained the company wants to early with 5G and “bring it to life in Stockholm, Tallinn and Helsinki in 2018”.

7. Stockholm snags fourth best startup ecosystem ranking

Stockholm has tied with Los Angeles for fourth place in SparkLabs Group’s annual analysis ranking the top ten cities with the best startup ecosystems.

It coincides with news that Stockholm-based e-commerce startup iZettle is approaching a $1 billion valuation, and will soon join Stockholm’s herd of unicorns which already includes household names like Skype, Spotify, and Klarna.

Stockholm’s multilayered startup ecosystem comprises venture capital, incubators and accelerators, corporate investors, educational institutions, industry events, co-working spaces, unicorns, meet ups, and government support. These individual factors combined are central to the city’s continued startup success.

8. Amazon Web Services (AWS) comes to Stockholm

In April, cloud computing giant Amazon Web Services (AWS) announced it would open three new data centers in the greater Stockholm region. The data centers that will comprise the new infrastructure region will be located in Västerås, Eskilstuna, and Katrineholm — all just around an hour by train from Stockholm.

“An AWS Region in Stockholm enables Swedish and Nordic customers, with local latency or data sovereignty requirements, to move the rest of their applications to AWS and enjoy cost and agility advantages across their entire application portfolio,” said Andy Jassy, CEO of AWS in a statement.

AWS joins Facebook as the latest in a string of internet giants that have establish data centers on Swedish soil.

9. Foreign investment keeps flowing to greater Stockholm

2017 was a major year of growth for the Stockholm region, with several international companies setting up in the capital and its neighbouring municipalities.

Just some of the major establishments throughout the year include German e-commerce company Zalando, which chose Brunna in Stockholm County for its first Nordic fulfillment center; Danish stone wool manufacturer ROCKWOOL, which plans to build a new facility in Eskilstuna; and next generation lithium-ion battery manufacturer Northvolt, which will open a new R&D facility in Västerås. (And let’s not forget that gaming studio from France-based Ubisoft mentioned above).

As Stockholm continues to grow at an unprecedented rate so do the job opportunities and the need for labour, setting up for an even more noteworthy 2018. Watch this space…

10. Urban farming crops up in Stockholm

Just because Stockholm is a city doesn’t mean it can’t have a flourishing agriculture industry!

Odlande stadsbasarer (Cultivating City Bazaars) is a new innovation project supported by Stockholm and run by 20 partners consisting of municipalities, property owners, innovation companies, and social companies.

Small-scale production and cultivation of vegetables will be tested in two pilot projects, one in an unused industrial space in Stockholm and the other in the H+ housing district in Helsingborg. The concept will be discussed at “Swedish Foodtech The Big Meet”, a food tech event taking place in Stockholm in June 2018.

Among other notable food tech innovations in the city, Stockholm-based startup Karma helps restaurants, grocers, and cafes to reduce edible food waste by selling the surplus to consumers at a lower price. The app was recently named one of the hottest Stockholm startups of the year by Wired.”

Participants at the DCD>Energy Smart event invited to visit the world’s largest data center heat recovery plant and Ericsson’s new global ICT center

At the DCD>Energy Smart confernce in Stockholm on March 13, two special site visits exploring two paths of building a sustainable city will be arranged for interested participants in the afternoon the day before the conference.

One of the visits will be to Ericsson’s new global ICT center where the world’s largets heat recovery plant with an initial capacity of 5 MW has been installed, soon to be expanded to 10 MW. At the visit, participants will be guided through the Ericsson data center and the cooling and heat recovery plant.

“Through the adoption of various energy efficiency measures, the data center industry together with the energy utilities can build scalable, flexible, and green data centers which are dynamic in their infrastructure,” says Jan Sjögren, head of global ICT centers building operations at Ericsson who will be guiding at the site visit and speaking at the event. “There is a great opportunity for the data center to recycle their waste heat, where we can potentially save on energy cost whilst generating profits as producers.”

The other site visit will be at Fortum Värme’s new Combined Heat and Power plant. Named KVV8 and recently launched, it is one of the world’s largest biomass CHP plants right in the center of Sweden’s capital. This facility is at the core of making Stockholm entirely fossil fuel free, together with other initiatives such as the extensive heat recovery and reuse from local data centers in the city. KVV8 has a production capacity of 350 MW heat and 150 MW power from biofuel.

Neues Rechenzentrum in Stockholm beheizt 10.000 Wohnungen

Das IT-Unternehmen Borderlight, das mit Kunden der öffentlichen Hand und der Industrie zusammenarbeitet, wird in Stockholm ein 5 MW Rechenzentrum bauen – und das Energieversorgungsunternehmen Fortum Värme wird die Abwärme rückgewinnen. Das Datacenter wird bewusst so für die Wärmerückgewinnung konzipiert, dass die wiedergewonnene Wärme für das Beheizen von 10.000 modernen Wohnungen reicht.

Rechenzentren verbrauchen riesige Mengen an Energie, die in Wärme verwandelt und meist in die Atmosphäre geblasen wird. Die Datacenter von Borderlight sind hingegen bewusst so konzipiert, dass so viel wie möglich der verbrauchten elektrischen Energie als Fernwärme genutzt werden kann. Einzigartig daran ist, dass mehr Wärme auf einer kleinen Fläche erzeugt wird, als sonst üblich. Mit anderen Worten: die Bladeserver – die eigentlichen Gehirne in Rechenzentren – werden mit einer Rack Dichte von bis zu 100 kW pro 19-Zoll-Rack gebaut. Das ist ungefähr zehnmal mehr als der Durchschnitt für herkömmliche Rechenzentren.

„Rechenzentren sind bereits heute sehr große Verbraucher an elektrischer Energie. Und der Verbrauch steigt stetig, im selben Maße, wie in der Gesellschaft zentralisierte Datenspeicherung benötigt wird. Wärmerückgewinnung in Rechenzentren erschließt eine ganz neue Energiequelle mit einem niedrigen ökologischen Fußabdruck, denn die so wiedergewonnene Energie, die sonst verschwendet worden wäre, ersetzt herkömmliche Fernwärmeproduktion. Die neue Energiequelle ist darüber hinaus äußerst zuverlässig, 24 Stunden am Tag, 365 Tage im Jahr. Die Unternehmen Borderlight und GoGreenHost haben einen festen Kundenstamm sowohl im öffentlichen Sektor als auch im Export von Speicherleistung mit großem Ausbaubedarf. Das Ziel ist, mit Fernwärme-Unternehmen in Schweden Verträge über 30 MW in diesem und weiteren 60 MW im kommenden Jahr zu unterzeichnen, verteilt auf Anlagen mit 1 bis 6 MW. Wir rechnen mit 6 bis 12 Monaten vom Baubeginn bis zur Inbetriebnahme“, sagt Sten Oscarsson, Geschäftsführer von Borderlight und GoGreenHost.

Die technische Lösung in den Datacentern kommt von GoGreenHost, der Schwestergesellschaft von Borderlight. In deren neuer Technik ist die Wärmerückgewinnung direkt in die Serversysteme integriert und die Wärmepumpen wurden neu designed. Die Abwärme wird so direkt auf die benötigte Temperatur für Fernwärme gebracht, die vom Energieversorgungsunternehmen Fortum Värme gekauft und an Stockholmer Privathaushalte geliefert wird. Der Stromanbieter Ellevio wiederum, beliefert die Datacenter mit Strom.

„Das neue Rechenzentrum bedeutet einen riesigen Schritt nach vorn für die Wärmerückgewinnung in Stockholm. Unter dem Namen ‚Öppen Fjärrvärme’ (= Offene Fernwärme) vermarktet ein Stockholmer Konsortium das Wärmerückgewinnungsangebot aus Handel und Industrie. So werden mit der Abwärme aus gewerblichen Kühl- und Tiefkühltruhen, aus Rechenzentren und anderen Abwärmequellen schon heute 20.000 moderne Wohnungen beheizt, anstatt die Abwärme in die Luft zu blasen. Mit dem neuen Rechenzentrum können wir diese Zahl in einem Schritt enorm weiter erhöhen. Außerdem siedelt sich Borderlight wegen der Wärmerückgewinnung bewusst in Stockholm an. Das ist ein fantastischer Erfolg für ‚Öppen Fjärrvärme’ und unsere großen Investitionen in ‚Stockholm Data Parks’“, so Erik Rylander, Sprecher für ‚Öppen Fjärrvärme’ beim Energieversorgungsunternehmen Fortum Värme.

Der regionale Energieversorger erzeugt energiesparend Fernwärme, Fernkälte und Strom und ist ein Joint Venture des Energieversorgungsunternehmens Fortum und der Stadt Stockholm. Zusammen mit seinen Kunden und den Stockholmern hat Fortum Värme einen Beitrag dazu geleistet, dass Stockholm als eine der weltweit nachhaltigsten Hauptstädte gilt.

Borderlight bietet öffentlicher Hand und Industrie betriebssichere Dienstleistungen
Borderlight liefert seit ca. 16 Jahren betriebssichere IT- und Telekommunikationsdienstleistungen an die öffentliche Hand und ist einer von fünf Dienstleistern, die ein Rahmenabkommen für Telefonie und IT-Kommunikation mit der staatlichen Einkaufszentrale Schwedens für alle Behörden sowie ca. 50 Prozent der schwedischen Kommunen und Landkreise haben ( Das Unternehmen hat einen jährlichen Umsatz von ca. 100 Millionen SEK (rund 11 Millionen EUR) und ein durchschnittliches EBITDA von 45 Prozent in den vergangenen zehn Jahren.

GoGreenHost entwickelt neue Technik für die Abwärmeverwertung in Rechenzentren
GoGreenHost entwickelt, baut und verwaltet großtechnische, verteilte Rechenzentren mit 1 bis 6 MW je Standort, die über Glasfaserleitungen zusammengekoppelt sind. Hierbei kommt selbst entwickelte Technik zur Rückgewinnung von verbrauchtem Strom zum Einsatz, so dass die Abwärme effektiv auf die für die Fernwärme benötigte Temperatur gebracht wird.

Mithilfe der Glasfasertechnik können so Rechenleistungen dort erbracht werden, wo die Abwärme mit passender Temperatur von dem jeweiligen Fernwärmenetz optimal genutzt werden kann. Die Rechenleistung kann durch das Glasfasernetzt auch flexibel dorthin verlegt werden, wo gerade ein entsprechender Bedarf an Fernwärme besteht, um simultan den Energieverbrauch zu optimieren und einen sicheren Betrieb zu gewährleisten.
