A technique to analyse the economic viability of offshore farms composed of wave energy converters is proposed. Firstly, the inputs, whose value will be considered after in the economic step, will be calculated using a geographic information software. Secondly, the energy produced by each wave converter is calculated. On the other hand, the economic factors are computed. Finally, the restriction that considers the depth of the region (bathymetry) is be put together to the economic outputs, whose value depends on the floating WEC. The method proposed was applied to the Cantabric and Atlantic coast of the North of Spain, a region with a good offshore wave energy resource. In addition, three representative WECs were studied: Pelamis, AquaBuoy and Wave Dragon; and five options for electric tariff were analysed. Results show the wave energy converter that has the best results regarding its LCOE, IRR and NPV, and which area is best for the development of a wave farm.
