CETO 5 – Perth Wave Energy Project

The Perth Project was the first demonstration of a complete grid-connected CETO system anywhere in the world, the only wave project to consist of three units operating together in an array and the only wave project globally to produce both power and freshwater.

The Project produced and sold both power and freshwater to the Australian Department of Defence to supply Australia’s largest naval base, HMAS Stirling, located on Garden Island. Our CETO 5 units were installed off Garden Island in late 2014, and the units were operated continuously for 12 months.

The desalination plant was part-funded through a $1.27m AusIndustry grant from the Clean Technology Innovation Program and involved the design and construction of a CETO Desalination Plant which desalinated seawater to produce freshwater.

Customer: Department of Defence
