World’s first ‘smart’ energy-storage battery to be fitted to Peterhead offshore floating wind farm

Hywind Scotland, the world’s first floating wind farm, be equipped with a battery to store power from the wind farm in Spring 2018.

The purpose is to “teach” the battery when to hold back and store electricity, and when send power to the grid, thus increasing value of the power.

Statoil and its minority partner, the Arabian energy firm Masdar, has awarded a contract to Younicos to deliver a 1MW battery system that will be connected to Hywind Scotland.

The Batwind storage solution project is the first battery storage system connected to a floating wind farm.

The two 10-foot modular battery containers will be placed at the Hywind Scotland onshore substation in Peterhead, Scotland.

Whereas a standard battery will charge and re-charge, the purpose of the Batwind storage solution project is to understand how a battery can help increase the value of the produced electricity and how a battery best can work together with the wind farm and the grid.

Sebastian Bringsværd, Statoil’s head of Hywind Development, said: “Through Batwind we are including software – or a brain if you like – on top of the battery to ensure that the battery behaves the way we want it to behave.

“We want the battery to automatically know when to hold back and store electricity, and when to send it out to the grid. Battery energy storage systems have existed in the market for several years and are rapidly developing.

“With more renewables coming into production it will be crucial to handle storage to ensure predictable energy supply in periods without wind or sun. Batwind has the potential to add value by mitigating periods without wind – and by that making wind a more reliable energy producer year around. This could expand the use and market for wind and renewables in the future.”
