Each CETO III pump has a maximum power output rating of 200 kW, but I suspect that is when the waves are 2 to 4 metres in height. From what I have heard from the company we can maybe estimate an average power output of about 100 kW per buoy in 1 meter waves (in the absence of published figues?). Best to be conservative I'd say. So you need 10 pumps for 1 MW.

These are my estimates only. The company seems to use a maximum power output rating but in real life this is not going to occur 100% of the time. Most sites they are targetting have 1m+ waves for 90% to 100% of the time so a lower estimate is appropriate in my opinion.

Having said that wind and solar are rated at their maximum output as well and we all know there is zero generation at night for solar and reduced generation when the wind is not blowing for wind.

So it really is just a matter of working out how many pumps you need= for the output you are after.

There is more information of a general nature about the wave energy resourse in Australia on the web site. There is a WWF document and also an earlier study.

But please DYOR - I'm not an engineer!
