Carnegie says first CETO 5 wave generator now operating

First unit producing power at Carnegie’s Garden Island project, first wave energy project in world to feature multi-unit deployment.


Australia’s Carnegie Wave Energy says it has successfully installed the first of its CETO wave energy units off Garden Island, near Perth, and the unit is now switched on and operating in line with expectations.

The 240kW CETO unit is the first of three units to be installed at what will be the world’s first multi-machine wave energy installation. It is a key test run for the full size CETO 6 units – which will be one megawatt each – which is currently under design and will be deployed in Australia – and elsewhere – in coming years.

Carnegie said in a statement on Tuesday that the first unit had been installed during calm conditions – and at its first attempt – and had been operating for one week. Wave heights had reached 3.5m. The unit is unique in that it sits entirely below the surface, increasing its ability to survive large storms.

Ivor Frischknecht, the CEO of the Australian Renewable Energy Agency (ARENA), which has helped fund the project, said the achievement at the Perth Wave Energy Project was of great significance for wave energy in Australia, which some have said could potentially deliver a large amount of Australia’s energy needs.

“This project demonstrates that wave energy has a real future as part of Australia’s energy mix,” Frischknecht said in a statement.

“It is also evidence that developing and commercialising new technologies takes considerable time, resources and financing. The CETO technology has been progressively scaled up over the past decade and has made great strides towards offering a competitive renewable energy solution.”

Carnegie’s achievements contrast sharply with the fortunes of other wave energy developers. Palermis last week said it could not attract any further funding, and has since entered administration. OPT, which had won funding for a 23MW facility off Victoria, has had that grant removed after failing to raise any funds.

Carnegie managing director Dr Michael Ottaviano said it marks the completion of a critical phase in Carnegie’s evolution and culmination of 3 years of design, financing, development and construction.

“It is also now the start of a new phase as we learn as much as we can about CETO 5 via the data collection and analysis that has already commenced,” he said in a statement.

“This initial CETO 5 unit is currently delivering significant amounts of real time data in regards to hydrodynamic movement, pressures, flows, loads, displacements and the like. All of which is critical to validating Carnegie’s proprietary computational models which can then be used with confidence in finalising the design of Carnegie’s 1MW CETO 6 system in 2015.”

The second CETO 5 unit is currently being finalised ready for deployment which will likely take place in December, subject to suitable weather conditions. Once confidence is established with its operation, installation of the third CETO 5 unit would follow.

The units have yet to be connected to the Western Power grid, but this will occur once Carnegie has full confidence in the power quality and system control being achieved. Integration of the wave energy into the desalination plant will occur after electricity generation and grid connection has been achieved.

The Perth Wave Energy Project has been under construction for approximately 12 months beginning with the installation of the CETO 5 unit offshore foundations last summer. The construction was proceeded by some 2 years of design, approvals, offtake, financing and procurement activity. More than $30m has been invested so far.

    This is a SCAM.
    It has NEVER produced any power and it never will.

      What makes you say it is a scam?

      Don’t know about this particular design. But I wouldn’t bet against wave generators producing power and or being used for desalinization.

      I’m sure a wave generators can work to produce electrical power and desalinization. Whether it is practical, is another matter.

      I’m somewhat skeptical as how effective it would be long-term. Will saltwater, seaweed, barnacles, weather, etc. make the lifespan so short and the maintenance so high that it might not be practical in the long run?

      I’d also be worried about how they might impact the environment. If you take energy out of the ocean, it could change the weather and ecosystems for the worse.

      It could be like windmills having a detrimental effect on weather and the ecosystem.

        If you look back at the history of the company you will see that this is a classic Green Widget Scam.

        It has been “coming real soon” for more than 10 years.

        Everytime it is almost ready for “commercialisation” and to be connected to the grid they announce that a new improved version which is of course “coming real soon”

        Fundamentally though, the concept is BULLPLOP even a short distance beneath the waves the amount of energy to be obtained is very small. I’m a surfer and I’ve also done a bit of scuba diving.

        Even if the buoy could be anchored so that it was only a few metres beneath the waves the motion would be very gentle compared to the energy of the wave at the surface. To remain in that zone the buoy would need constant adjustment to correct for the tides.

        Google “Ocean Power Technologies – A scam or WHAT?”

        for an explanation of how these wave widget scams work.
        I was right about that one, hundreds of millions of dollars down the executives trousers and nothing but a pile of rusty metal to show for it. Company is now almost bankrupt.
        I know my scams!

          I tend to agree with your assessment on this particular type of “wave generator”. A bobber style “wave generator” is unlikely to be effective beneath the surface.

          “Green” scams are commonplace. Being green is a common selling point for scammers to naïve investors that don’t know the difference between a scam and real science.

          While I believe this “wave generator” is likely to fail. I think other forms of “wave generators” might have some potential, though probably very limited and may harm the environment, thus may not be as “green” as touted.
