Rabbalshede Kraft has commissioned a 20MW/20MWh battery storage unit at its 46MW Femstenaberg wind farm in southern Sweden, creating the company’s first fully integrated energy park.
The facility stores excess power during high-wind periods and supplies electricity when demand rises, while also providing balancing and frequency regulation services to the Swedish grid, according to the company.
Rabbalshede Kraft said the hybrid system will enable optimised production and support system flexibility.
“This is a milestone for Rabbalshede Kraft and for Swedish energy supply,” said Tobias Lundberg, business developer at Rabbalshede Kraft.
“With our first energy park, we are showing what the future of electricity production looks like – where storage, wind and soon also solar work together to create a robust and fully renewable system, which can deliver sustainable energy, when it is needed most,” said Lundberg.
The developer said the project marks the start of further investment in hybrid renewable parks combining wind, storage and solar to advance Sweden’s clean energy transition.
