Statoil launches Batwind: 1MWh battery storage for pilot offshore wind project

A new battery storage solution for offshore wind energy will be piloted in the world’s first floating wind farm, the Hywind pilot park off the coast of Peterhead in Aberdeenshire, Scotland. Statoil will install a 1MWh Lithium battery based storage pilot system in late 2018.

Hywind Scotland, located 25 km offshore Peterhead, will consist of five floating wind turbines. The 30 MW wind park is currently under construction and start of electricity production is expected in late 2017.


Batwind will be developed in co-operation with Scottish universities and suppliers, under a new Memorandum of Understanding (MoU) signed in Edinburgh on 18 March between Statoil, the Scottish Government, the Offshore Renewable Energy (ORE) Catapult and Scottish Enterprise.

Battery storage has the potential to mitigate intermittency and optimize output. This can improve efficiency and lower costs for offshore wind. The pilot in Scotland will provide a technological and commercial foundation for the implementation of Batwind in full-scale offshore wind farms, opening new commercial opportunities in a growing market.

Statoil has a strong position in offshore wind. By developing innovative battery storage solutions, we can improve the value of wind energy for both Statoil and customers. With Batwind, we can optimize the energy system from wind park to grid. Battery storage represents a new application in our offshore wind portfolio, contributing to realising our ambition of profitable growth in this area.

—Stephen Bull, Statoil’s senior vice president for offshore wind

A structured programme is now being established under the MoU to support and fund innovation in the battery storage area between Statoil and Scottish industry and academia. This program will be managed by ORE Catapult and Scottish Enterprise.



1 MWh is 2 minutes of a 30 MW windfarm.
This is why you can really only use batteries for load shaping an power quality, it is VERY expensive to shift large amounts of power in time.
