Perth Project

This project will be the first demonstration of a complete grid-connected CETO system anywhere in the world, the only wave project to consist of more than one wave unit connected together and the only wave project to produce both power and freshwater.

The project will sell 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 with the Project expected to be producing power in 2015.

In May 2012, the PWEP was awarded a $13.1 million Australian Federal Government grant from the Australian Renewable Energy Agency’s Emerging Renewables Program (ERP). This is matched with grant funding from Government of Western Australia’s Low Emissions Energy Development (LEED) Program. The WA funds will come from Carnegie’s existing $10 million State Government funding agreement which was previously used for the commercial CETO unit demonstration in 2011.

The CETO Desalination Plant is 50% funded through a $1.27m AusIndustry grant from the Clean Technology Innovation Program and involves the design and construction of a CETO Desalination Plant which will desalinate seawater to produce freshwater. The plant will be directly powered by CETO hydraulic energy from an offshore CETO system. The aim is to demonstrate that CETO wave energy driven seawater desalination has the potential to significantly and sustainably reduce the amount of electricity consumed, and hence the associated greenhouse gas emissions produced, by seawater desalination.

Objectives

As the PWEP is a demonstration not a commercial project, the key objectives are 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.
  • 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.
