have encountered significant technical issues and project overruns that have resulted in significant increases in project costs. These issues have resulted in new UK nuclear projects failing to secure project financing. Similarly, SMR technology is not currently economically competitive with offshore wind in the UK. Following the Fukushima nuclear disaster public support for new nuclear has fallen. In response, the UK government increased its previous commitment for 40GW of Offshore wind capacity by 2030. As of 2020, this represents a 355% increase over current capacity in 10 years. It is expected the Crown Estate will announce multiple new leasing Rounds and increases to existing bidding areas throughout the 20202030 period to achieve the government's aim of 40GW. Scottish offshore In addition to the 25GW scoped under the Round 3 SEA, the Scottish Government and the Crown Estate also called for bids on potential sites within Scottish territorial waters. These were originally considered as too deep to provide viable sites, but 17companies submitted tenders and the Crown Estate initially signed exclusivity agreements with 9companies for 6GW worth of sites. Following publication of the Scottish Government's sectoral marine plan for offshore wind energy in Scottish territorial waters in March 2010, six sites were given approval subject to securing detailed consent. Subsequently, 4sites have been granted agreements for lease. The complete list of sites including power updates and developer name changes: In 2022 Crown Estate announced the outcome of its application process for ScotWind Leasing, the first Scottish offshore wind leasing round in over a decade and the first ever since the management of offshore wind rights were devolved to Scotland. 17 projects were selected with a capacity of 25 GW. List of operational and proposed offshore wind farms Onshore The first commercial wind farm was built in 1991 at Delabole in Cornwall; it consisted of 10turbines each with a capacity to generate a maximum of 400kW. Following this, the early 1990s saw a small but steady growth with half a dozen farms becoming operational each year; the larger wind farms tended to be built on the hills of Wales, examples being Rhyd-y-Groes, Llandinam, Bryn Titli and Carno. Smaller farms were also appearing on the hills and moors of Northern Ireland and England. The end of 1995 saw the first commercial wind farm in Scotland go into operation at Hagshaw Hill. The late 1990s saw sustained growth as the industry matured. In 2000,
