Our mission

Imagine a place where the energy is green and excess data center heat isn’t wasted. Imagine Stockholm.

Stockholm Data Parks is an initiative by the City of Stockholm, district heating and cooling provider Fortum Värme, power grid operator Ellevio and dark fiber provider Stokab.

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.

To make it happen, we target to make Stockholm an attractive hub for large data centers which employ heat recovery. We do it by bringing together, preparing and offering all the necessary infrastructure elements at attractive greenfield sites and sites for conversion suited for data center activity.

We believe it’s a win-win where the data center industry can reach the next level of cost efficiency and sustainability and at the same time be part of the City’s transition to a fully sustainable energy system.

Stokab is owned by the City of Stockholm and lays the foundation for IT use in Stockholm by providing a passive fiber-optic communications network in the region. The company has been tasked with expanding, maintaining and leasing connections to this network.

The network is open for all players on equal terms and Stokab is obliged to lease to all stakeholders who wish to gain access. Because it is unlit or ’dark’ fiber that is leased, customers are responsible for providing their own active equipment.

Karin Wanngård, Mayor of Stockholm City

“So far, data centers have been built with little consideration for the environment. We want to change that. We want future data centers to be even more cost efficient and truly green. With that objective, we are determined to make Stockholm a major hub for sustainable data centers. Together with other key players we have set up a partnership - Stockholm Data Parks - to make it happen.”
