This paper develops a methodology to determine the economic feasibility of implementing offshore wave energy farms on the Portuguese continental coast. This methodology follows several
phases: the geographic phase, the energy phase, the economic phase, and the restrictions phase. First,
in the geographic phase, the height and the period of the waves, the bathymetry, the distance from
the farm to the shore, from farm to shipyard, and from farm to port, are calculated. In the energy
phase the energy produced by each wave energy converter is determined, and in the economic phase,
the parameters calculated in the previous phases are used as input to find the economic parameters.
Finally, in the restrictions phase, a limitation by the bathymetry will be added to the economic maps,
whose value will be different depending on the floating offshore wave energy converter (WEC). In this
study, three wave energy converters have been considered, Pelamis, AquaBuOY, and Wave Dragon,
and several scenarios for electric tariffs have been taken into account. The results obtained indicate
what the best WEC is for this study in terms of its levelized cost of energy (LCOE), internal rate of
return (IRR), and net present value (NPV), and where the best area is to install wave energy farms.
