Residual DigiPlex data centre heat to warm Oslo residents

In Norway, DigiPlex, a leading data centre supplier, and Norway's largest district heating supplier, Fortum Oslo Varme AS, a company jointly owned by the Municipality of Oslo and Finland-headed energy utility major Fortum Oyj, have signed a Letter of Intent (LoI) on the recovery of heat from DigiPlex's data centre at Ulven in Oslo. The agreement contributes to new district heating production corresponding to the energy needs of approximately 5 000 Oslo apartments.

According to DigiPlex, a progressive data center industry must do what it can to reduce its environmental footprint and globally, data centres account for two percent of the world’s annual carbon dioxide (CO2) emissions and three percent of power consumption. In Oslo, district heating is already provided from renewable sources.

Every time we go online, stream a TV series or use a cloud service, a process starts in a data centre. We, as individuals, have a larger impact on climate change if these processes are initiated in a data centre operated on non-renewable energy and more so from one where waste heat is released into the atmosphere, said Gisle M. Eckhoff, CEO of DigiPlex.

With the statutory phasing out of fossil energy sources for heating and urban development, demand for district heating is increasing. With Fortum Oslo Varme planning to increase heat production, the company has sought out sources of renewable energy that are suitable for production.

At DigiPlex, we are proud to reinforce our leading role in our industry regarding climate change, using renewable power and the waste heat from our data center at Ulven in Oslo to keep the citizens of Oslo warm. Digitization must move towards a greener world, and our cooperation with Fortum Oslo Varme is an important step in that direction. From autumn 2019, when end users in Norway browse the web, they will be indirectly contributing to the heating of apartments in Oslo, said Gisle M. Eckhoff.

District heating is and will be in the future, an important part of the city’s infrastructure. District heating in Oslo covers approximately 20 percent of the capital city’s current heat demand.

The district heating system operated by Fortum Oslo Varme is a 600 km thermal energy distribution system in Oslo and is a great tool for moving energy from areas with excess to where energy is needed. We are very pleased to have signed this agreement with DigiPlex, said Eirik F. Tandberg, Managing Director of Fortum Oslo Varme.

With the increasing construction activity in Oslo and the ban on the use of fossil oil for heating, there will be an increased need for renewable sourcing in the years to come. Through planned increases in capacity at DigiPlex’ data centre, the volume of recovered heat supplied to the district heating system will increase.

This type of third party delivery into the district heating network benefits both the environment and the city’s population. Fortum Oslo Varme is already recovering energy from the sewage of Oslo, and by recovering the surplus heat from data centres, we further increase the share of recovered heat in our production and strengthen Oslo’s cycle-based energy system. By using resources already available, instead of letting them go to waste, we make district heating and energy use in buildings a part of the circular economy. Water-borne heating solutions in buildings are what makes this innovation possible,, Tandberg said.

Oslo Municipality is positive to the agreement. Norway is attractive for the establishment of data centres due to access to competitive green power and stable power grids.

The City Government of Oslo welcomes this agreement. The cooperation between Fortum Oslo Varme and DigiPlex is a good example of environmentally friendly industrial development, said Kjetil Lund (A), Vice Mayor for Business Development and Public Ownership in Oslo.

Data centre cooling

The Letter of Intent also includes delivery of cooling to DigiPlex’ facility.

In addition to using the waste heat from the data center to produce heat for Oslo, we will deliver cooling to DigiPlex. According to the agreement, Fortum Oslo will establish an energy production unit with associated heat pumps and pipelines on the site of DigiPlex here in Oslo, said Knut Inderhaug, Head of Customer at Fortum Oslo Varme.

DigiPlex says that it wishes to set the “standard for sustainable solutions” in the data centre industry. The company represents the new generation of data center providers that help enterprises with costeffective solutions through its innovative and environmentally-friendly facilities. DigiPlex operates its data centers exclusively on renewable power, with its Norway facilities drawing on Norwegian hydropower plants.

The reuse of waste heat is the next step in our journey towards a more sustainable society and sustainability is at the core of our business’ DNA. Our data centre in Oslo is already energy efficient, but the ability to utilize surplus heat to heat homes and commercial buildings will help customers further reduce their environmental footprint, said Eckhoff.

Echoff says that the company will continue to focus on the reuse of waste heat in all Nordic markets.

In addition to this agreement with Fortum Oslo Varme, we recently announced a heat reuse agreement in Sweden with the district heating company Stockholm Exergi, and in Denmark, we also aim to support a sustainable society in similar ways, ended Eckhoff.
