Commissioning of Windpark Fryslân has been pushed backed due to the turbulent weather, the complex logistics of the project, and COVID-19, according to project developers. Contractor consortium Zuiderzeewind is expected complete the installation of the wind turbines in the third quarter of 2021.

Windpark Fryslân, which was originally expected to be fully constructed at the beginning of this Summer, consists of 89 Siemens Gamsea SWT-DD-130 wind turbines and is being built in the IJsselmeer near Breezanddijk. It will be the largest inland water wind farm worldwide. When full operations are achieved, the wind farm is expected generate around 1.5 terawatt hours (1,500,000 megawatt hours) of power annually, enough green electricity to power approximately 500,000 households.

Since the construction of the first wind turbines,
Windpark Fryslân has been supplying energy to Eneco customers under a 15-year PPA. In their contract, Eneco and Windpark Fryslân have agreed that large consumers of energy in the province of Fryslân will also have the option of purchasing sustainable energy from the wind farm.

Construction continues at the site with the developers celebrating the recent completion of the projects array cables. The connection with the Oudehaske high-voltage substation near Heerenveen, two 55-km-long underground 110-kV cables, has now been put into operation. In addition, the nature island at Kornwerderzand has been constructed and a start has been made with the monitoring of the nature around the wind farm.

Each wind turbine consists of three tower parts, the nacelle and the rotor. Due to the limited width of the locks around the IJsselmeer, the parts are shipped to the IJsselmeer and assembled there. The tower parts and the nacelle come to the IJsselmeer via Amsterdam. The three rotor blades are transported to the port in Oude Zeug. There are two installation platforms in the IJsselmeer, the Sarens Soccer Pitch and the Tom-Wim. Working with two platforms, Zuiderzeewind can install two wind turbines at the same time. After construction, every wind turbine is inspected from foundation to nacelle, after which it is put into operation.
