Case Studies
Mutriku Wave Power Plant, Spain
The Mutriku Wave Power Plant is a commercial wave energy power plant located in the Basque Country, Spain. It has a capacity of 2 MW and was commissioned in 2011. The plant uses Oscillating Water Column (OWC) technology, which converts the energy of ocean waves into electricity by capturing the movement of air in a chamber.
The plant has been operating successfully for over a decade and has generated over 100 GWh of electricity. It has also helped to reduce Spain’s reliance on fossil fuels and greenhouse gas emissions.
Pico Pico Wave Power Plant, Portugal
The Pico Pico Wave Power Plant is a wave energy pilot plant located on the island of Pico, Portugal. It has a capacity of 0.25 MW and was commissioned in 2010. The plant uses Pelamis technology, which consists of a series of articulated segments that float on the surface of the water and move in response to ocean waves.
The Pelamis segments are connected to a generator, which converts the energy of the moving segments into electricity. The plant has been operating successfully for over a decade and has generated over 1 GWh of electricity. It has also helped to reduce Portugal’s reliance on fossil fuels and greenhouse gas emissions.
