The dismantling of nuclear power plants is a highly complex and demanding task. Special tests and approvals are required. Often, temporary arrangements or new components are needed to ensure the remaining operations and to optimise energy or operating costs.

Generating electricity from sunlight is an important step towards sustainable power generation. Photovoltaics is not only worthwhile for industrial and commercial customers, but also makes sound business and environmental sense for communities.

Wind energy is one of the mainstays of renewable energy in Germany. The challenges lie in connecting the wind farm to the main grid — especially when they are offshore. Our many years of experience in transmission networks and distribution grids as well as in substation construction make us a reliable partner for connecting onshore and offshore wind farms — at all voltage levels.

Our Center of Compentece for Geo-Information Technology (CeGIT) carries out comprehensive planning services for the realisation of construction projects for you as network operator — whether this involves single packages or the complete solution up to completion of the project. The CeGIT range of services encompasses medium to extra-high voltage lines. We plan cable and overhead line projects and also implement fibre optic cable, water and gas routings.

EHV/HV overhead lines are just as individual as they are complex. Various country and business-specific standards paired with constant changes in network structures require in-depth expertise and high levels of flexibility in power line construction.

Close to cities, industrial areas, wind farms – everywhere, where EHV/HV voltages cannot be transmitted via overhead lines, that`s where underground cables are used. Just as for overhead line construction, we are also a skilled and experienced partner in constructing EHV/HV cables systems.

As a collection and distribution point, substations are one of the most complex elements of the transmission network. The constantly increasing demands of network operators, energy suppliers and decentralised generators require specialist knowledge in the construction and modernisation of these facilities. With our many years of our experience and our cross-vendor product expertise, we are the right partner for EHV/HV substations.

Distribution grid stations in local networks are the interconnections between the medium voltage and low voltage networks. In industry, distribution grid and transformer stations provide secure electrical supply for businesses. We plan, deliver, install and refurbish MV/LV installations and stations of all types using supplies from all manufacturers.
