Electrical Engineering as the Backbone of Production
Stable electrical networks, properly designed protection systems, and complete, traceable documentation are crucial for the availability, safety, and scalability of industrial plants. Our electrical engineering services cover the entire lifecycle—from the development of robust power concepts to the design of switchgear, protection, and grounding systems, and the sizing of cable and wiring routes.
We combine engineering expertise with reliable implementation: from basic and detailed engineering through UPS/emergency power systems, EMC-compliant plant concepts, and hazardous areas to commissioning, testing, and retrofitting of existing facilities. Through close integration with automation, instrumentation, and plant engineering, we create electrical infrastructures that operate reliably, are easy to maintain, and can safely accommodate future expansions.

Data and Digitalization
Data and digitalization are an integral part of our electrical engineering services.
We structure and digitize plant data—from planning and BIM models to audit-compliant documentation. In addition, we integrate concepts for the collection, processing, and transfer of operational and energy data—as the basis for transparent commissioning, efficient operation, maintenance, and future optimizations throughout the entire plant lifecycle.
Automation of Energy Systems
A modern power plant can only operate reliably when its electrical infrastructure, protection systems, and control systems work together seamlessly. In power centers, distribution facilities, and power plant environments, we automate the monitoring of load flows, protection trips, and grid switching—ensuring stable, efficient, and transparent operation.
