Power generation and transmission

Manage the transformation of the energy industry

Power plants and substations are our core expertise. Trust in our knowledge when it comes to safeguarding your power supply.

EQOS Energie ensures a dependable and secure energy supply – around the clock. Our customer projectsextend from the North Sea to the Alps, from the Danish to the Italian border. The transformation of the energy sector poses new challenges for the distribution networks: Large amounts of wind-generation energy need to be transported from Northern Germany to the southern part of the country. In Austria, there are a great number of hydroelectric power plants and the energy they generate must be sent where it is needed. Therefore, we support customers in the energy sector during the maintenance and expansion of the transport networks. This includes upgrading existing substations and lines as well as the construction of new facilities and connections. But we also offer our electrotechnical services for the climate-friendly expansion of district heating networks to ensure the supply of citizens.
