Recent economic study into the cost profile of power from tidal lagoons has found that a portfolio of three UK tidal lagoons, in operation by 2021, would deliver large-scale low carbon power at a significantly cheaper price than offshore wind.
Energy economists at Pӧyry, a management consultancy, identified a volume-weighted levelised cost of energy for the three lagoons as around £100 MWh.
Tidal Lagoon Swansea Bay released the following video that shows how the UK’s first three tidal lagoon power plants would deliver significantly cheaper power:
