Vattenfall has opened its Energypark Haringvliet plant in Netherlands, which combines wind, solar and battery storage.
Haringvliet is the Swedish developer’s first project of this kind, the company said.
Combining the technologies will produce energy at a lower cost, make a more efficient use of available grid capacity, and have less impact on the environment, Vattenfall said.
It anticipates Haringvliet will serve as a blueprint for future projects.
Haringvliet is located 20km south of Rotterdam and consists of six wind turbines, 115, 000 solar panels and 12 sea containers containing batteries.
All three technologies jointly share the same grid connection.
The energy park is expected to produce approximately 140 gigawatt-hours of electricity annually, an amount equivalent to the consumption of 40,000 Dutch households.
Vattenfall head of business unit for onshore wind Sandra Grauers Nilsson said: “To reach our climate goals, we have to accelerate the energy transition.
“Energypark Haringvliet is a great example how to use available resources as efficiently as possible.
“It combines wind, solar and batteries in such a way that over the span of a year we supply more sustainable energy, at lower costs.
“And at the same time it has lowest possible impact on environment, grid and surrounding area.”
Wind and solar power complement each other well during different seasons and can share the same grid connection, leading to less power needed to be reserved in the grid.
The battery ensures that the net remains in balance, Vattenfall said.
Vattenfall head of solar Claus Wattendrup said: “The opening of Haringvliet is a great step for Vattenfall’s wind and solar business, a proof point for our competence to develop and build cross technology projects in Europe.”
