The MALEG demonstrator was sent to the geothermal plant of “Fernwärme Haag GmbH” in Austria. The plant was installed and hydraulically hooked-up to the geothermal water supply line by a mixed team of scientists, engineers and technicians of different parties of the consortium. Fully automated operation could be successfully launched. The scientists have remote access to the system, which allows the modification of operation settings and the collection of measurement data, which will be used to teach the AI models in the coming project phase.
