The "world's first community-owned tidal power generator" became operational in Bluemull Sound off Yell, Shetland in early 2014. This 30 kW Nova Innovation device feeds into the local grid, and a 100 kW tidal turbine was connected in August 2016. At the opposite end of the country a 2010 consultants' report into the possibility of a scheme involving the construction of a Solway Barrage, possibly south of Annan, concluded that the plans "would be expensive and environmentally sensitive." In 2013 an alternative scheme using the VerdErg Renewable Energy spectral marine energy converter was proposed for a plan involving the use of a bridge along the route of an abandoned railway line between Annan and Bowness-on-Solway.
