Vattenfall is to develop its first hybrid wind-solar-storage energy park by adding photovoltaic and energy storage capacity at its Haringvliet wind farm project in the Netherlands.

The Swedish energy group says that the first stage of the building work for the project has started, with preparations being made for installation of six wind turbines in the north of Goeree-Overflakkee island between Middelharnis and Stad aan 't Haringvliet.

Once the 22 MW wind farm is completed, around 124 000 solar panels will be installed, adding 38 MW to the site, and will be later followed by installation of a 12 MWh battery unit housed in 12 shipping containers.

Vattenfall says that hybrid energy plants are in “important building block” in the energy transition and will help to reduce energy costs for consumers.

“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,” said Gunnar Groebler, Senior Vice President and Head of Business Area Wind, Vattenfall. “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.”
