Wave energy developer Carnegie Wave Energy (ASX: CWE) is pleased
toadvise that its commercial scale CETO 3 unit has been
successfullyinstalled offshore from Garden Island in Western
Australia and isproducing power in lines with expectations.

Installation of the CETO system has taken place offshore from
Australiaslargest naval base on Garden Island in Western Australia.
The final step, theconnection of the buoyant actuator (BA) to the
balance of the CETO system,occurred over the weekend. The system
was immediately energised and isproducing hydraulic power exactly
as expected.
Carnegies Managing Director Dr Michael Ottaviano said,
This is the most significant milestone in Carnegies history and
follows morethan 5 years of in-ocean testing of scale CETO
prototypes. It now allows us to

plan our project pipeline roll out with confidence. Carnegies
CETO technology
was already the only wave technology to have produced
desalinated water; itis now the only commercial scale wave unit
ever deployed and operated inAustralia and the Southern
Hemisphere.
Id like to thank all of Carnegies team which has put in a
tremendous effortover the last 18 months and, in particular, the
last 3 months. Their effort, alongwith our key contractors, has
allowed us to achieve this major milestone safelyand effectively.
Additionally, were grateful for the support of the StateGovernment
of Western Australia through the LEED grant program and
theAustralian Department of Defence. Dr Ottaviano said.
The CETO units data acquisition and remote control system is
also operatingto design and allows the collection and transmission
of performance data andcomplete system control in real-time from
the CETO control centre in WestPerth. Carnegie engineers are
manning the centre around the clock toconduct power optimisation
trials and monitor performance as well as carryingout detailed data
analysis.
Carnegie expects to have analysed performance data within 6 to 8
weeks andwill retrieve the CETO unit on completion of the primary
testing period forvisual inspection.
In parallel with manufacture, design and installation
activities, Carnegie hasbeen developing the design of a small
scale, grid-connected 2 to 5MWdemonstration project. A finalised
conceptual design is now complete andwork on the detailed design
will commence shortly.

About the Perth Wave Energy Project
Carnegies Perth Wave Energy Project is located offshore in the
ocean betweenGarden Island and Five Fathom Bank at a depth of
approximately 25 metres. Upon
completion, it will be Australias first commercial scale wave
energy project.
The primary aim of the project is to demonstrate the CETO
technology in commercialoperation. The project site could also be a
base for a desalination pilot projectutilizing Carnegies CETO
technology.
About CETO
The CETO system distinguishes itself from other wave energy
devices by operatingout of sight and being anchored to the ocean
floor. An array of submerged buoys istethered to seabed pump units.
The buoys move in harmony with the motion of the
passing waves, driving the pumps which in turn pressurise water
that is deliveredashore via a pipeline.
High-pressure water is used to drive hydroelectric turbines,
generating zero-emissionelectricity. The high-pressure water can
also be used to supply a reverse osmosisdesalination plant,
replacing greenhouse gas emitting electrically driven pumpsusually
required for such plants.
