nLighten data center in Stuttgart to feed excess heat into local heating network
nLighten and Wärmelösungen Synergiepark Stuttgart to supply it.schule and DEKRA buildings.
Start of network expansion in Synergiepark Stuttgart. Project will supply nearby public and commercial buildings through partnership with Wärmelösungen Synergiepark Stuttgart
5 February – Frankfurt – The nLighten data center in Stuttgart will soon feed excess heat into the local heating network, supporting the sustainable supply of the municipal it.schule, a training center for IT and media professions, as well as DEKRA buildings in the Möhringen district.
To make this possible, nLighten is partnering with Wärmelösungen Synergiepark Stuttgart, a joint venture between Stadtwerke Stuttgart GmbH and e-con AG. The companies have now signed the required cooperation agreement. This forward-looking project marks the beginning of an expanded heating network in Synergiepark Stuttgart and is expected to go live later this year. It is supported by funding from the German Federal Ministry for Economic Affairs and Energy.
A model project for the industry
The initiative demonstrates how data center operators can work with municipal and private sector partners to reduce their emissions. As nLighten powers its data center with renewable electricity, the recovered excess heat is not only sustainable, but also sets an example for the entire industry.
The excess heat from the data center will be sold to Synergiepark Stuttgart, which will process and distribute it. The local infrastructure is designed to deliver up to 1.8 megawatts of heat output.
A closed-loop water system serves as the heat transfer medium, capturing heat from the data center´s servers and using heat pumps to raise it to the temperature level required by the customers. As supplier, Synergiepark Stuttgart ensures a sustainable, resilient and cost-efficient heat supply for the area.
Andreas Herden, Managing Director Germany at nLighten, explains:
The heat reuse project in Stuttgart is another milestone for nLighten and demonstrates how data centers can become active shapers of the energy transition.
”Following our successful project in Eschborn, we are once again proving that Europe’s digital infrastructure can be designed not only to be powerful and connected, but also sustainable.”
Ulf Hummel, Managing Director of Wärmelösungen Synergiepark Stuttgart, said:
The excess heat project with nLighten creates an added value for everyone involved: it delivers climate-friendly heat for our customers, strengthens the data center’s sustainable business model, and represents an important step towards decarbonising Stuttgart’s heat supply.
”As a young company, Wärmelösungen Synergiepark Stuttgart set out to provide climate-neutral heat to the entire industrial area in Vaihingen and Möhringen. Connecting the data center is the reward for the many years of planning.”
