Norwegian energy giant Equinor has installed the first batteries for offshore wind in Peterhead.
The batteries are connected to the Hywind floating wind farm, and the grid.
Their capacity is the equivalent of more than 128,000 iPhones.
As the wind is not always blowing, energy storage technologies like batteries and other ways of storing electricity, is expected to become increasingly important to secure grid stability.
Sebastian Bringsvaerd, development manager for Hywind and Batwind, said: “The variability of renewable energy can to a certain extent be managed by the grid.
“But to make renewable energy more competitive and integrate even more renewables to the grid, we will need to find new, smart solutions for energy storage to provide firm power.
“How to do this in a smart and value creating way is what we are aiming to learn from Batwind.”
Batwind is fully financed by Hywind Scotland partners, Equinor and Masdar, and is a first step towards a scalable, global renewables energy storage system.
