The Blauwwind consortium behind the
Borssele 3&4 offshore wind farm in the Dutch North Sea is celebrating the project entering full operations. The construction of the 731.5 MW wind farm, with a total of 77 V164-9.5 Vestas turbines was completed on-time, with official commissioning on 6 January 2021.

“This is a great achievement of everybody involved”,
said Roeland Borsboom, project director and CEO for Blauwwind. “In difficult circumstances, partly due to the COVID-19 pandemic, we were still able to construct the windfarm at a swift pace, without noteworthy problems or incidents. The five partners, the project organisation and the (sub)contractors collaborated incredibly well, while I also would like to mention the smooth cooperation with both TenneT, the owner of the offshore substation Borssele Beta, and Østed, our neighbours of the Borssele I&II project. Today we proudly celebrate the hand-over of the project to the Blauwwind operations team”.

The Blauwwind consortium consists of Partners Group (45%), Shell (20%), DGE (15%), Eneco Group (10%) and Van Oord (10%). It was awarded the project in December 2016, with a subsidy bid of 5.45 eurocents per kWh representing a dramatic cost reduction at the time. Shell and Eneco Group have also secured 15-year Power Purchase Agreements (PPAs) from the Consortium, under which each will buy 50% of the power generated by the windfarm. Total expected power generation is 3,000 gigawatt hours (GWh) per year.
Shell Energy Europe Limited and Eneco have secured contracts to each sell 50% of the power produced.

Monopile installation began in October 2019 and first power was achieved on 7th August 2020. As the Balance of Plant contractor, Van Oord was responsible for the design, engineering, procurement, construction and installation of the 77 monopile foundations, 117 km of 66 kV inter array cabling and 77 MHI Vestas
V164-9.5 MW turbines.

The wind farm connects to the Borssele Beta platform, built and operated by TenneT, which converts power from 66Kv to 220 kV and transport power to the onshore electrical substation at Borssele. The connection was completed in July 2020.


O&M will be carried out from a permanently manned Service Operations Vessel which has her home base in Oostende.
