Australian wave energy developer Carnegie Wave Energy has announced that its next-generation commercial scale CETO unit (CETO 4) has been manufactured and delivered to its deployment location on Reunion Island, France.
CETO units operate submerged in the water, anchored to the ocean floor. They consist of an array of buoys tethered to seabed pump units, which are driven by the buoys as they move with the motion of the passing waves.
The pumps drive pressurised water onshore via a pipeline, which powers hydro-electric turbines.
The CETO unit will now undergo pre-deployment testing by French marine defence contractor DCNS, and once pre-deployment testing is completed, offshore installation is currently scheduled to take place during the Southern Hemisphere summer.
Successful testing and operation of CETO 4 is planned to be followed by a grid-connected 2 MW CETO project at the same site with plans for subsequent further expansion to 15 MW.

To date, the project has been two thirds funded by French Government grants, and the grid-connected project will receive a marine energy feed-in tariff.
