Battery Batwind stores energy floating wind park

The world’s first floating wind park, Hywind, offshore Peterhead in Aberdeenshire, after Scotland, will store it’s renewable energy in a 1MWh lithium battery.

In 2018, Norway’s Statoil intents to test the battery which is named ‘Batwind’.


The battery should flatten the peaks and valleys in the generated energy and thus improve the efficiency of the offshore wind farm and reduce the cost of energy generated down.

The Norwegian energy company Statoil wants to test the battery concept at the floating Hywind wind farm which is now under construction. When the tests are successful, larger offshore wind farms can also be supplied by this green energy storage battery Batwind.

Peak demand

Batteries are one of new frontiers in energy investment. Renewables producers can tap into stored energy to instantly meet peaks in demand or compensate for periods of low wind and poor sunshine.

“Battery storage has the potential to mitigate intermittency of wind energy and optimize output,” Statoil said.

Wind Park

The pilot park will cover around 4 square kilometers, at a water depth of 95-120 meters. The average wind speed in this area of the North Sea is around 10 meters per second. The wind park has been verified through six years of successful operation of a prototype installed off the island of Karmøy in Norway.

Statoil has green ambitions

Stephen Bull, senior vice president for offshore wind, in the message of Statoil

‘(…) “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 realizing our ambition of profitable growth in this area.” (…)’

In order to develop the Batwind, Statoil signed an agreement with the Scottish government, Offshore Renewable Energy (ORE) Catapult and Scottish universities and companies.

The Scottish Minister of Energy Fergus Ewing

‘(…) “This will help maximize the renewable generation of the Hywind offshore wind farm, whilst informing the case for energy storage and demonstrating the technology’s ability to support renewables in Scotland and internationally.
A recent industry and Government report, produced by the Carbon Trust, concluded that if the energy market was adapted to appropriately recognize the benefits of electricity storage to the wider system, this could lead to savings of up to £50 a year on an average energy bill and a system wide saving of up to £2.4bn a year by 2030.”
