Ramboll carried out site development for a potential offshore wind farm on Mejlflak in Aarhus Bay, Denmark. Ramboll's contract with Havvind Århus Bugt A/S included geophysical/geotechnical investigations and the entire EIA process including economic assessments.
120 MW in the Aarhus Bay
The wind farm is located in Aarhus Bay close to Mejlflak. It has a capacity of maximum 120MW, equivalent to the annual electricity consumption of approximately 120,000 households. The company behind the wind farm is Havvind Århus Bugt A/S, which consists of five energy companies around Denmark's 2nd largest city Aarhus – Brabrand Elselskab, Galten Elværk, NRGi, Viby Elværk, Østjysk Energi and Vindmøllelaug Århus Bugt.
Ramboll's services included geophysical/geotechnical investigations, the entire EIA process including Natura 2000 impact assessment, visualisation and pre-feasibility studies including economic assessments.
The site is close to internationally environmentally protected areas and is visible from both the mainland of Jutland and the island of Samsoe. This presented a challenge for the EIA process and the public acceptance of the project in general. Further, ship impact from heavy ship traffic in the area was a factor that had to be considered.
Offshore expertise entrance to wind farm market
Strategically this project was very important to Ramboll. After winning the site investigations for the Anholt Offshore Wind Farm in 2009, the Mejlflak project placed Ramboll as one of the leading consultancy companies in Denmark within site development and environmental assessment of offshore wind farms.
By combining offshore experience from different departments, Ramboll delivered a multidisciplinary consultancy service that is unique.
