Wind turbines taller than the tallest buildings in Canary Wharf could be built offshore in the 2020s, as the industry uses bigger machines to cut costs, a leading manufacturer has said. MHI Vestas makes what are believed to be the biggest offshore turbines to be deployed commercially to date, with blades spanning a 164-metre (538ft) diameter and their tips reaching to 195 metres (640ft) above sea level. The 8-megawatt (MW) capacity machines are currently being installed by Dong Energy at its Burbo Bank Extension wind farm, off the coast of Merseyside. Anders Bach Anderson, senior product manager at MHI Vestas, said he believed wind turbines with blades spanning more than 200 metres (656ft) diameter, and with capacity of at least 12MW, were “likely” before 2030, and said they could potentially span in excess of 230 metres (755ft). Such machines could have a capacity of more than 15MW and tip heights reaching up to 260 metres (853ft) above sea level – taller than the One Canada Square, which at 235m (771ft) is the tallest building in Canary Wharf.
