Dong is planning a staggering 6.5GW by 2020 — roughly the same amount as the world’s current installed capacity.

But with lingering doubts about the future of support schemes in key markets such as the UK and Germany, why is the utility rushing into the sector with such bravado — risking 50% of its annual spending on gigantic turbines up to 100km from shore? And can Dong, already the world’s leading offshore developer, really afford to pay for it all?

According to Dong chief executive Henrik Poulsen, the company’s goal is “to maintain market leadership [in offshore wind], and help to develop the technology and industry”.
