Our workflow
Consultation
We assess your project, inspect the site if required and clarify technical conditions early – creating a sound basis for the decisions ahead.
Grid operator coordination
We align grid operator requirements, connection conditions and technical data, keeping the design compliant, traceable and ready for coordination.
Planning
We develop the plant layout, electrical design and protection and metering concept, then combine them in clear, implementation-ready documentation.
During construction
We support execution, review technical implementation and interfaces, and resolve site deviations before they affect the schedule.
Grid connection
We verify the final conditions, coordinate the grid connection and track open points through a reliable transition into commissioning.
Commissioning
We coordinate the final technical steps and verify documentation and prerequisites so your plant can begin operating safely and without unnecessary delays.
