Another thread going sideways again......oh well 

Create your own green energy creation thread rather than destroy one not about this subject.

No, I can't see it either, but the maximum installed capacity is 400MW, the storage capacity is 3.3 million cubic metres and the maximum head of water is about 210m, so I'm guessing someone with the right set of skills might be able to work it out from that?

I'll bite, although I often wonder whether I've slipped a decimal in these calculations.  Hopefully someone will point it out if I have.

Lifting one kg by 1m is around 9.8 joules, one cu.m of water raised by 210m = 9.8 x 1000 x 210 = 2,058,000 = 0.57kWh That sounds small. Multiply by 3.3 million gives 1,881 MWh.  That's not accounting for efficiency or the fact that 210m is the maximum head  whereas we really want the average.
