Vattenfall to build hybrid energy park at Goeree-Overflakkee

Visualisation Haringvliet hybrid energy park

Vattenfall is building a 60 MW hybrid energy park, consisting of solar panels, wind turbines and batteries at Haringvliet, at Goeree-Overflakkee. The project, involving a total investment of 61 million euro, is scheduled to be completed by September 2020. 

As a first step, Vattenfall will install 6 windturbines with a maximum height of 150 m in the north of Goeree-Overflakkee between Middelharnis and Stad aan ‘t Haringvliet. Preparatory work have already started. The wind turbines will have an estimated combined power rating of 22 MW which is the equivalent of the electricity consumption of around 27,000 households. Once the wind turbines have been installed, the solar farm can then be built, consisting of 124,000 solar panels with a total of 38 MW – enough to supply green electricity to around 12,000 households. The batteries – supplied by BMW and with a capacity of 12 MWh – will be installed in 12 shipping containers on the solar farm.

Through this project, Vattenfall combines wind turbines with solar panels and energy storage. Gunnar Groebler, Senior Vice President and Head of Business Area Wind, Vattenfall: “Vattenfall wants to enable fossil-free living within one generation and hybrid power plants are an important building block for us in the direction of 100% fossil-free power generation. The complementary wind and solar generation profiles reduce the load on the grid compared to a single generation technology. Hybrid systems provide less pronounced peaks and we see fewer total times without production. This leads to a more efficient use of the network infrastructure. In addition, the costs for grid connection are significantly reduced compared to stand-alone systems. This will reduce the cost of renewable electricity and ultimately benefit customers.”
