"The extra swell and lower running costs mean that CETO 6’s electricity will be cheaper than CETO 5’s. Mr Ottaviano reckons that if CETO 5 were deployed en masse, in “wave farms” with a capacity of 25MW, it could produce electricity at a cost of 30-40 US cents a kW-hour, which is competitive with diesel. At a similarly large scale, CETO 6’s electricity would, Mr Ottaviano says, cost about 20 cents a kW-hour. Ultimately, he thinks, economies of scale could bring that down to 12-15 cents a kW-hour for a 100MW wave farm. That is about the same as the cost of grid electricity in this part of Western Australia, allowing for the subsidy now given to renewable energy sources."
