    The Mutriku Wave Power Plant was commissioned as an Oscillating Water Column-based power plant to supply energy to the power grid. As a test site, it has been designed to allow testing and demonstration of PTO systems and, in particular:
    • air turbines;
    • air valves;
    • power generators & converters;
    • control strategies;
    • energy storage & power quality equipment;
    • sensors;
    • other ancillary equipment.
    The Mutriku test site has all the necessary licenses for conducting tests.
    To ensure suitable levels of safety for personnel and the environment, certain minimum technical requirements must be met. These are set out in the BiMEP Installation Guide.
