The study, carried out bymanagement consultants Pӧyry for developer Tidal Power Lagoon (TPL), found thatthe energy plants – concrete-walled structures in whichincoming tidal flow is trapped and later released through turbines to generateelectricity – could produce power at a levelised cost of energy(LCoE) as low as £90/MWh ($148/MWh). That is a LCoE similar to onshore wind, large-scalesolar PV, nuclear and gas-fired generation.
