Wave energy

The world’s first wave energy farm, located off the coast of northern Portugal, is up and running and generating a total of 2.25MW, enough to power 1,500 homes.

Ocean Power Delivery (OPD) has supplied the first three Pelamis P-750 “advanced wave energy conversion technology” machines, with another 28 machines being planned along the Portugal coast within a year.

When complete, the entire farm will generate a total of 22.5MW for state-run power company Energias de Portugal, enough to power 15,000 homes.

This project is also expected to displace more than 60,000 tonnes of CO2 per year.

The Pelamis has a similar output to a modern wind turbine.  It is cylindrical, with four main tube segments that are linked by hinged joints.

The machine is semi-submerged and generates power from the wave-induced motion of the joints.

Future wave farm projects will consist of multiple interlinked machines connected to the shore by a submerged cable.
