Utility infrastructure

Infrastructure is the backbone of every energy supply system. Besides the conceptual design and dimensioning of infrastructure systems, the approval planning on public or private ground is a particular focus of the activities of HGC.

The expertise of HGC ranges from house connection to long-distance supply, for supplying media like natural gas, biogas, hydrogen, compressed air and special gases. Even for the planning and construction of pipelines for transporting liquid media – such as drinking and industrial water, reservoir water and pipes for district cooling and district heating – provides HGC engineering services.

Another business segment is the planning and processing of infrastructure for optical fiber networks for telecommunication business.

Examples of projects from all areas can be found in our reference list.
