Power systems

The transition towards an energy sector based on renewable energy sources requires intelligent solutions to ensure efficient and reliable transport of energy from the point of production to the consumer. A multi-disciplinary approach is called for. 
High power lines

The fundamental transformation of our energy system from energy production based on fossil fuels to renewable energy is still in its early years. However, an increasing number of large-scale renewable energy projects are now under construction with the aim to provide clean energy for millions of households.

This change in the composition of producing units towards a more decentralized and fluctuating power production demands a new perspective on the complete power transmission infrastructure by increasing capacity between regions. This development will be based on both high voltage AC and DC technology with an increase in offshore grid connections.

Ramboll’s approach

At Ramboll we acknowledge that the development of the energy sector requires a holistic approach in order to provide long-term solutions for the coming generations. We focus on providing solutions that can uphold the quality of supply throughout their entire lifetime.

For Ramboll, the technical solutions are only part of the delivery. It is clear that any project on the global market is characterised by increasing project complexity, demand for flexible solutions, greater focus on stakeholder involvement and decreasing cost (CAPEX & OPEX).

Ramboll’s consulting expertise

Ramboll can offer engineering consultancy services ranging from design of HV equipment and substation automation all the way to offshore platform design and onshore constructions including civil works.

Furthermore, Ramboll offers consultancy services for engineering and design of HV overhead lines. We provide solutions for mast design and predesign covering geotechnical and topographical investigations and cables.

Our HV cable competencies range from route planning, surveying and engineering to interface handling. We have experience working both offshore and onshore. We work in urban areas, remote areas as well as with offshore transmission cables or wind park array cables.
