About the project
Blauwwind is working on the construction of the Borssele III & IV offshore wind farm, which will have an installed capacity of 731.5 MW. Covering 146 km2, the wind farm will comprise 77 turbines, producing enough power to provide around 825,000 Dutch households with renewable electricity.
In 2013, some 40 parties came together to finalise the Dutch Energy Agreement for Sustainable Growth, which states that to realise 16% renewable power production by 2023 a total of 4,450 MW of offshore wind power needs to be generated.
North Sea locations
To realise the Energy Agreement for Sustainable Growth, the Dutch government has selected a number of areas of the North Sea where offshore wind farms can be constructed.
In this process, the Dutch government facilitates all the conditions that are necessary to construct a wind farm: favourable location, appropriate permits and connection to the national energy grid via TenneT. The Borssele III & IV offshore wind farm will be connected to the grid via the TenneT Borssele Beta offshore substation.
Research and subsidy
In addition, the Dutch government has carried out research into the composition of the site, the seabed, the wind speeds and metocean data, which has helped prevent delays in construction following approval of the permit. The government is also providing subsidies for the construction of wind farms.

Tender bid submitted
The Blauwwind consortium submits a tender for the right to develop, construct and operate the Borssele III & IV offshore wind farm.
Tender bid won
The Dutch government announces that the Blauwwind consortium has won the bid for the Borssele III & IV offshore wind farm.
Financial close achieved
Agreement is reached on project financing, enabling the project to progress to the construction phase. Partners Group officially joins as fifth shareholder.
Royal Netherlands Navy clears unexploded ordnance
During a seabed survey, two pieces of unexploded ordnance from WWII are identified at the construction sites. These are cleared with support from the Dutch Navy.
Foundation installation commences
Installation of monopile foundations commences. The monopiles are loaded onto the Aeolus at the assembly yard at Maasvlakte and installed 25 km off the coast of Zeeland.
Archaeological investigation completed
During an earlier seabed survey, two cannons were retrieved. Following relevant research, the cannons are to be restored and displayed in Vlissingen.
Cable installation commences
The first inter-array cable (the cable joining individual wind turbines) is successfully installed using the cable laying vessel Nexus.
Offshore substation topside installed
The offshore substation will enable Blauwwind to connect the wind farm to the onshore electricity grid operated by TenneT.
Foundation installation completed
The last foundation is installed by the Aeolus. Following some modifications to the vessel, it will commence turbine installation. The turbines will be loaded in Vlissingen.
Start of wind turbine installation
V164-9.5 MW MHI Vestas turbines will be loaded onto the Aeolus at Vlissingen and installed offshore.
Van Oord, MHI Vestas, TenneT and Blauwwind will work together to safely commission the wind farm. Power generation will then commence.
