Carnegie Wave Energy completes design of 1MW CETO 6

Carnegie Wave Energy says it has completed concept design of CETO 6 generation unit, which will have roughly four-times rated capacity of CETO 5, at 1MW.


ASX-listed wave power developer Carnegie Wave Energy has revealed it has completed the conceptual design phase of its CETO 6 Project at Garden Island in Perth.

The WA company – whose CETO 5 technology makes up the world’s first grid-connected wave energy array, located off Garden Island – said its CETO 6 design had a number of advantages over the earlier model, including a roughly four-times increase in rated capacity to 1MW.

The new design also eliminates the need for heavy offshore lifts (and associated costly heavy lift vessels), adding to a much simplified installation and maintenance program.

Further the CETO 6 has more advanced control systems, with power generation contained inside inside the Buoyant Actuator, which goes to increased system efficiency.

An electrical export cable (or umbilical) is also used to deliver the power onshore, reducing
transmission losses compared to the current CETO 5 Perth Wave Energy Project, which uses a pipeline with high pressure fluid.

“The CETO 6 concept design is the culmination of work commenced in 2012 and incorporates
lessons learnt from the Perth Wave Energy Project, recent wave tank testing in Scotland, internal design and modelling studies and design work undertaken with Carnegie’s supply chain,” the company said in an ASX media release.

The team has also identified a preferred project site for the CETO 6 array, some 10km offshore from Garden Island.

Detailed design is targeted for completion in mid-2016. The CETO 6 project has been partly funded by a five-year, $20 million loan facility from the Clean Energy Finance Corporation, alongside an $11 million grant from the Australian Renewable Energy Agency (ARENA).

    My skepticism of this technology is diminishing.

    Excellent development, but if desalinated water is required along with electricity production, then there will still be a place for the CETO 5 unit as well.

      I’ve been a long time fan of Carnagie, but what attracted me most to this technology was its ability to produce both Power and desalinated water. It makes sense to replace the pipes with a cable, thus generating electricity offshore and greatly opening up the potential sites for this technology, but I still can’t help be somewhat disappointed.

      CETO 5. HAhahhah Hilarious. These guys are a bunch of Spivs who have been ripping off investors for over a decade. Laughable stuff.

    If its underwater and 10 klms offshore its safe to say there is zero visual pollution and not much chance of any health side effects to the nearest human inhabitants. No doubt there would be an onshore building but that could be quite asthetically pleasing if they make the effort. No smoke stacks or cooling silos. So ticks for those considerations. Wave energy is an enormous unexploited source of energy. Great to see there are efforts to tap this resource.

    However good the tech is, investors would be more inclined to back Carnegie if only they’d start commercialising it faster.

    It is still relying on undrawn govt loans, undrawn CEFC loans, R&D tax refunds and MoUs for its business model.

    Commercialisation is long overdue and continually upgrading its kit does not bring in the $$$. i’d respectfully request to CWE to start showing its long-suffering investors a bit of return for our patience. They’d certainly be interested to hear when the Dept of Def will start paying for all the free desal water it gets from the onshore CETO5 plant.
