no major UK-based wind turbine manufacturers: most are headquartered in Denmark, Germany and the USA. In 2014, Siemens announced plans to build facilities for offshore wind turbines in Kingston upon Hull, England, as Britain's wind power rapidly expands. The new plant was expected to begin producing turbine rotor blades in 2016. By 2019, blades were being shipped in large numbers. The plant and the associated service centre, in Green Port Hull nearby, will employ about 1,000 workers. The facilities will serve the UK market, where the electricity that major power producers generate from wind grew by about 38 per cent in 2013, representing about 6 per cent of total electricity, according to government figures. At the time there were plans to continue to increase Britain's wind-generating capacity, to 14GW by 2020. In fact, that figure was exceeded in late 2015. On 16 October 2014, TAG Energy Solutions announced the mothballing and semi closure of its Haverton Hill construction base near Billingham with between 70 and 100 staff redundancies after failing to secure any subsequent work following the order for 16 steel foundations for the Humber Estuary in East Yorkshire. In June 2016, Global Energy Group announced it had signed a contract in association with Siemens to fabricate and assemble turbines for the Beatrice Wind Farm, at its Nigg Energy Park site. It hopes in the future to become a centre for excellence and has opened a skills academy to help re-train previous offshore workers for green energy projects. During 2021, £900M were invested in UK offshore wind power manufacturing. The UK offshore wind industry occupied 19,600 people directly in 2021, while thousands others worked in related businesses. Specific regions Wind power in Scotland Wind power is Scotland's fastest growing renewable energy technology, with 5328 MW of installed capacity as of March 2015. This includes 5131 MWof onshore wind and 197MW of offshore wind. Whitelee Wind Farm near Eaglesham, East Renfrewshire is the largest onshore wind farm in the United Kingdom with 215 Siemens and Alstom wind turbines and a total capacity of 539MW. Clyde Wind Farm near Abington, South Lanarkshire is the UK's second largest onshore wind farm comprising 152 turbines with a total installed capacity of 350MW. There are many other large onshore wind farms in Scotland, at various stages of development, including some that are in community ownership. Robin Rigg Wind Farm in the Solway Firth is Scotland's
