The Crown Estate UK Wave and Tidal Key Resource Areas study (2012)[1] assessed the UK’s theoretical maximum resource for tidal stream, barrage and lagoon resource at 95 TWh/year (32 GW), 96 TWh/year (45 GW) and 25 TWh/year (14 GW) respectively. The Department’s Technology Innovation Needs Assessment [2] (TINA) published in 2012 estimated that tidal stream energy could practically deliver up to 20-30 TWh/year around 2050.
