Ørsted is officially inaugurating the Borssele 1&2 offshore wind farm off the Dutch coast today (6 September 2021). With a capacity of 752 MW, it is currently the largest offshore wind farm in operation in the Netherlands.

Ørsted won rights to the
Borssele 1&2 site in July 2016, with an average bid strike price, excluding transmission costs, of EUR 72.70/MWh for the first 15 years of the project's operation. The project is jointly owned by Ørsted and Norges Bank Investment Management (NBIM). It consists of 94 Siemens Gamesa Renewable Energy SG 8.0-167 DD turbines. It is located 23 km off the coast of Zeeland (Westkappele), and is expected to provide power to over 500,000 households annually.

Construction for the project's onshore substation and installation of its offshore grid connection began in 2018. The turbine foundation installation started in January 2020 and was completed by June that year despite COVID-19. The 94 monopiles were fabricated by Sif and EEW SPC. The 94 transition pieces came from Bladt and EEW OSB. Installation was completed by DEME’s installation vessel

Installation of the turbines began in April 2020 and was completed using installation vessels
Sea Installer and Sea Challenger from DEME Offshore, were deployed to complete the installation. The wind farm generated first power that same month. This was followed by full commissioning of all the turbines in Novermber 2020.
