The invention concerns the field of renewable marine energy and relates to a power plant comprising a structure which can be built on a coastline, comprising multiple outriggers which are made of reinforced concrete and between which multiple motion transducers are arranged linearly. These transducers follow the rise and fall of the waves by sliding on guideways incorporated in the internal faces of the outriggers. This arrangement makes it possible to precisely direct the trajectory of the motion transducers while still protecting them against bad weather and other adverse meteorological conditions. The linear configuration of the motion transducers also makes it possible to capture the energy from a single wave several times, thus ensuring optimum, continuous and synergistic operation and a very high capture rate, irrespective of the climatic conditions or the height of the waves. The dimensions of this power plant can be adapted depending on the intended production capacity and according to the hydrodynamic conditions in the deployment zone.
