Nlighten's data center in Stuttgart-Möhringen will integrate into a local district heating network, initially serving the It.Schule and Dekra. A cooperation agreement was signed in February 2026, with operations expected to commence within the year.

The project, a joint venture between Stadtwerke Stuttgart and E-Con, involves the latter providing technical planning, while the former manages commercial aspects. The system aims for up to 1.8 MW heat output, increasing as the data center operates. Nlighten emphasizes that waste heat utilization is a core component of its operations, with plans for similar projects at other German sites.
