Batwind

Batwind - 1.2MW battery system launched for Hywind floating offshore wind farm

With Batwind in operation, it will for the first time be possible to store energy produced from an offshore wind farm.

The battery storage solution was presented in Peterhead, Scotland today by Batwind partners Equinor and Masdar. Electricity produced at the world’s first floating offshore wind farm Hywind Scotland, located 25 kilometers off the coast of Peterhead, will be transported via cables to an onshore substation where the 1 MW batteries are placed and connected to the grid.

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.

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.

Hywind development manager Sebastian Bringsvaerd said Equinor, along with project partner Masdar, are hoping to learn how to create “smart and value creating” storage solutions from the project.

“While there are many energy storage products and solutions in the market, the battery software solutions are less developed.

“We want to teach the battery when to hold back and store electricity, and when send power to the grid, thus increasing value of the power.

“It will be really exciting to see how we can develop the combined battery and software solution and make batwind as smart as possible.”

Hywind features five Siemens Gamesa 6MW turbines atop spar foundations and entered commercial operations last year.
