Stadtwerke Lübeck has launched its first self-operated data center in the northern German city of Lübeck. Built to strengthen the city’s digital sovereignty, the facility will support business-critical and sensitive applications for local companies and features multiple layers of redundancy.
While Stadtwerke Lübeck has not released details about the data center’s exact construction cost in euros, the firm did confirm to DCD that it had invested a “low single‑digit million [euro] figure.”
“The data center is a milestone for Lübeck,” said the CEO of the Lübeck Municipal Utilities Group, Dr. Jens Meier, in a statement. “With the data center, we are securing local data sovereignty, increasing the resilience of central systems, and creating a competitive advantage for businesses, public administration, and companies in critical infrastructure sectors.”
Demand for the data center’s services was reportedly so strong that nearly all available capacity was taken up by the end of its first development phase, according to the company. The project follows a survey conducted by Lübeck’s Chamber of Industry and Commerce in August 2022, in which half of the 156 member companies said they would consider using a regional data center, citing advantages such as data sovereignty, local support, and improved availability compared to foreign facilities.
The new municipal data center will be powered by two 100kW combined heat and power plants currently under construction in the area. While the data center will be the primary consumer of the electricity generated, excess power will be fed into the grid. At the same time, waste heat from the plants will be used to warm homes in the nearby Geniner Ufer district. Rooftop solar panels with a capacity of 180–200kWp will provide additional on-site generation, while heat produced by the servers will be repurposed to warm adjacent areas within the building.
Central systems in the data center have also been equipped with multiple redundancies to protect against interruptions in the network and the threat of cyberattacks. It was for this reason, a Stadtwerke Lübeck Gruppe spokesperson told Energate Messenger, that the launch date for the facility was delayed from September 2024 until this year. "At the same time, aspects of sector coupling were integrated more comprehensively into the overall concept - including the planning consideration of further expansion stages,” they said.
