Engineering and management services for the development of transmission lines

HVDC & HVAC engineering and management services start from the design of overhead lines, including tower design, route- , insulator- and surge arrestor selection, and the SVC design.

Moving forward the completion of the project, engineering studies such as the sub-synchronous resonance and the insulation-coordination are provided.

The initial design is outlined to the detailed design in order to manage the entire project up to specification, bid evaluation, construction, testing, commissioning and final acceptance.


  • Engineering: route selection, cable rating, specification, environmental assessment, tendering, owner engineering, structure and civil job design, substation design
  • Construction Supervision: inspection and testing of materials and line components, foundation testing, site supervision and commissioning supervision.


For decades, we have played a major role in the complete preparation, analysis, design, construction management and inspection of energy structures, high voltage transmission lines and distribution systems worldwide. Our team have in-depth knowledge of network and substation design from 11 kV to 400 kV.

We enjoy an excellent working relationship with many TNOs and DNOs as well as with many international electrical utilities, who entrust us with much of the energy infrastructures’ development of their country.
