They state "Over 14,000 cumulative hours of operation", which for 3 units is just over 50% utilisation, and "12,000kWh over the demonstration cycle" (on the web site).
10kW of rooftop solar panels in Perth will produce a lot more than 12,000kWh in a year. At a cost of $10k for your solar panels vs $30m for the CETO5 project would indicate that wave energy is orders of magnitude more expensive.
Apologies for the round numbers, but hopefully CCE has a sleeve full of rabbits. Based on their latest spedning , looks like there is only a very small team left, so I can't see how they will be able to do anything of note, without a massive capital raise, or some white knight. There are better options for the twiggies and cannon brookes to spend their money on at the moment. It is going to be very difficult for them to hang in there unless they have some tech they can sell or license.
