The Closed Distribution System Groen (Gesloten Distributiesysteem Groen, GDG) is the closed system (CS) through which eight wind farms from Windplan Groen, one solar farm and three large-scale battery projects connect to the high-voltage grid. All of the electricity is bundled through two cable circuits and fed into the public grid. As the grid operator made only a single connection available, a shared infrastructure was essential. This makes GDG a critical link for Windplan Groen, the largest onshore wind farm in the Netherlands.
Ventolines guided the development and delivery of this CS across all stages, such as development, engineering, legal structuring, contracting, financing, technical contracting and construction management. We have been responsible for the asset management of the network for the past three years.
During the development of Windplan Groen, the challenge arose of bringing together the electricity output of 86 wind turbines onto a single grid connection. The solution was a Closed System, a privately owned electricity grid in a geographically defined area, with no more than 500 connections and no household consumers.
This approach provided a reliable and efficient method of connecting the wind farms to the national high-voltage grid. In collaboration with our project partners, we also developed a bespoke Energy Management System (EMS) for the GDG.
The scale and complexity of the GDG are unique in the industry. Its successful commissioning marks a significant milestone in the implementation of Windplan Groen, and demonstrates that collaboration and technical expertise are essential to the energy transition. Ventolines is proud to have led this project, which forms the basis of the large-scale supply of sustainable electricity across Flevoland.
