Netzkontor

Profile

The Netzkontor Group is a specialised service provider for critical infrastructure, with a clear focus on telecommunications and energy networks. Under its umbrella, the group brings together a broad range of services covering the entire life cycle of network infrastructure—from planning and construction supervision to installation, operations and network management.

The group’s origins lie in netzkontor nord, founded in 2008 and specialising in the planning and supervision of fibre‑optic network rollouts, as well as in its subsidiary OpenXS, which provides network management services based on long‑term contracts with fibre‑optic network operators. Comparable services are also offered to utilities and grid operators in the electricity market, positioning the group as a reliable partner for the expansion and operation of critical energy infrastructure.

As part of a consistently pursued buy‑and‑build strategy, the service portfolio has been selectively expanded. The acquisition of NKG Fiberservice added installation and fault‑repair services in particular, including work at network level 4 (in‑house infrastructure). In both planning and installation, activities have been further strengthened and scaled in recent years through additional strategic acquisitions.
