Perth 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 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. The first next generation CETO 5 unit was installed off Garden Island in late 2014, and all three CETO 5 units were in operation for over 13,000 cumulative hours.

The Perth Project was supported by a $13.1 million Australian Federal Government grant from the Australian Renewable Energy Agency (ARENA) and $10m in grant funding from Government of Western Australia’s Low Emissions Energy Development (LEED) Program.

The CETO 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.


As the PWEP was a demonstration rather than a commercial project, the key objectives were mainly focused on demonstrating the viability of the CETO technology and learning from the experience of deploying and operating multiple CETO units and the complete CETO system.

Project Objectives

  • Demonstration of a larger capacity CETO unit than any CETO unit developed to date.
  • Long term operation and survivability spanning four seasons.
  • The production of utility-compliant electricity by generating and exporting power to the grid for a sustained period.
  • The production of main water-compliant desalinated freshwater for a sustained period.
  • Verification of the accuracy of Carnegie’s computational CETO system modelling against the measured Project performance.
  • Confirmation of the feasibility of the deployment, operation and recovery of the Project’s major elements including pipeline, CETO units and foundations.
  • Recording of the environmental interactions of the Project in order to demonstrate and verify that it has minimal impact.
  • Demonstration of Carnegie’s ability to plan, resource and execute a commercial scale CETO project.
