Cost modelling and design optimisation of tidal stream turbines [PDF]
, 2021 A newly developed cost model for tidal stream turbines is presented. The model is based on (a) an existing tidal stream turbine cost model, (b) published CapEx data from an operational tidal stream turbine array, and (c) wind turbine cost data. The new cost model is utilized to establish cost-effective tidal stream turbine design, with the aim of ...
