Danish pension provider PKA and Kirkbi A/S, the parent company of the Lego Group, will each take a 25 per cent share in the project.
Dong will provide operation and management services for the project, as well as selling the power on behalf of the other investors.
The Burbo Bank Extension will be situated in the Irish Sea, around four miles off the coast of Liverpool and is expected to be fully commissioned in the first half of 2017.
Lego Group chief executive and president Jørgen Vig Knudstorp said: “This investment is another substantial step for the Lego Group towards balancing our global energy consumption with renewable energy capacity. Our goal is to fulfil this by 2020 and beyond, as we want to make a positive impact on the planet our children will inherit.”
PKA chief executive Peter Damgaard Jensen said: “In the spring of 2015 we blacklisted 31 coal companies, which have since lost more than 60 per cent of their value. In the same period, the return on our offshore wind farms has been more than 7 per cent. … We are proud to be able to provide a good return to the pension savers and at the same time make a positive difference.”
The company recently announced it had made a final investment decision on Hornsea Project One, which at 1.2GW will be the world’s largest offshore wind farm when it is completed in 2020.
