World first wave energy project gets switched on

  •  Australian Minister for Industry and Science opens Perth Wave Energy Project
  • First Electricity exported into state electricity grid at HMAS Stirling
  • World's first grid connected wave energy array
  • Project to generate clean electricity and zero emission desalinated water
  • Perth Wave Energy Project to supply power and fresh water to HMAS Stirling

A world-first wave energy project was switched on yesterday at Garden Island.

The project will provide renewable electricity for the Federal Department of Defence, powering HMAS Stirling, Australia’s largest naval base. The desalination component will be able to supply up to one-third of Stirling’s freshwater needs.

Energy Minister Mike Nahan said Australian company Carnegie Wave Energy had developed a world-first grid-connected wave energy generator and desalination plant capable of producing both electricity and fresh water.

“This technology has been developed over 10 years, can operate in a variety of water depths, swell directions and seafloor conditions and can generate power for both onshore and offshore consumption,” Dr Nahan said.

“Through State and Federal funding and support, Carnegie has taken Western Australia to a world-leading position in wave energy commercialisation.”

Environment Minister Albert Jacob said the State Government had contributed $9.96 million from its Low Emissions Energy Development (LEED) fund towards the development of the technology and the project.

“Wave energy is very predictable and is not tied to the daily cycles of sun and wind, making it a particularly valuable energy resource. The wave farm harnesses the enormous and untapped renewable energy resource in our ocean waves and converts it into two of the most important resources on the planet - clean energy and fresh water,” Mr Jacob said. 

Dr Nahan said the project was a boost to the State’s economy.

“Projects like this create employment for West Australians and provide ways to tap into the State’s rich renewable energy resources,” he said. 

Overall, Carnegie Wave Energy has now spent $100 million, more than $70 million of this in WA since the LEED funding announcement, showing the potential economic benefits of innovative technologies.

The company has now started work on a commercial-scale project on Garden Island with larger buoys and a new generation of the technology.
