In the course of making your recommendations I think you gave some thought to modification of the existing Emu Downs wind farm?---Yes.
What sort of modification did you have in mind?---The potential expansion of the wind farm by the addition of additional wind turbine generators.
Did you have in mind the addition of extra generating capacity?---We had that in mind, yes.
And by that I mean adding to the substations?---No.
Well, is it not the case that the substations out there can only handle 80 megawatts?---Yes.
In order to put more electricity into the grid you have to increase the capacity of the substations?---At the peak load. The wind farm does not operate at its peak capacity only but irregularly, when the wind is blowing
I understand that. You can add some more turbines to try to generate more electricity when the wind is blowing?---Yes.
But I want to understand whether the modification that you had in mind included increasing the capacity of the substations?---No, it did not.
Did you have in mind any particular extent of possible addition of turbines?---At that time we had asked consideration of the existing noise limitations for the wind farm what our expansion capability might be. We had at that time not yet received confirmation as to what the expansion might be within those limitations.
So did you have in mind at all a potential number of additional turbines that might be installed?---My own view was that we were potentially looking at up to six further turbines.
So you didn't think you had in mind any more than six?---Not given the limitations that were
Did you participate in the process of verbal questions and answers with Transfield and Stanwell people?---A number of times, yes.
That's in relation to the consent question?---Specifically, on March 6 I participated in that meeting.
Did you say or did you hear anyone else from Griffin say that you had in mind the possible addition of up to six turbines?---Yes. We had I believe discussed an expansion of the Emu Downs project. I am not - my recollection with regard to the number six being used I can't confirm for you.
So you don't know whether you ever put to Transfield that what was in your mind at least was up to six additional turbines?---I don't believe that's the case.
You don't think you did tell them?---I believe that we discussed expansion of the wind farm but I don't believe we discussed six.
When you discussed expansion did you make clear what you had in mind, that is, adding turbines, not adding generating capacity?---I don't believe the conversation went to that depth.
Right. The turbines come at about $2 million each on their poles and installed, don't they?---I would suggest that that perhaps is a bit light given current increases.
You mean light not late?---Light. Yes.
You think it's a bit more than two million?---I believe it would be.
But it's of that order, isn't it? Say two and a half million?---Fair enough.
We're not talking $10 million a?---No, we wouldn't be talking
No, so around two and a half million dollars to design, install and get another turbine going and hooked up to the system. Correct?---Correct.
Is it the case that at the moment there are some - there are 48 turbines on poles?---That's correct.
And they are connected to two 40 megawatt substations?---That's correct (ts 145 - 147).
