6700 foot^3  189.7228721664 meter^3
----------- = ----------------------
 second       second    
     (volume flow rate)     

Each gate will flow 190 cubic meters/sec
Guess 50 meters of head
You get spillway loss of 83,876 kw or 84 MW per gate
All 20 gates would be 1677 MW 

Total generation is 154 MW or 213,000 horsepower or about a thousand car motors.
So two spill gates at 168 MW are more than the full generation capacity.

So whats the power check look like full blast?
154 MW times $.07/KWH or $70/MWH = $10,780 per hour or $7.76 million per month
Of course average reality is a fraction of this...ain't that much water.

So what's the spill gate loss?
84MW times $70/MWH = $5880 per hour per gate

Just curious. Time to go swimming now.

ain't that much water...................................


Just noticed the figures for how much water.


Generation capacity is 183MW.  Cannot be continuous because of lack of water.

Annual generation is 327 MKwH.


So what would yearly (8760 hours/year) generation be at full tilt?  1603080 MWH/year

So what is the duty cycle or percent of full blast generation in reality?

327 MKwH/1603080 MKwH      

Looks like about 20% of full generation used yearly on average.

So whats the power check look like full blast?
154 MW times $.07/KWH or $70/MWH = $10,780 per hour or $7.76 million per month
Of course average reality is a fraction of this...ain't that much water.

So the power check is derated to 20%.

Martin Dam makes $2156/hour    or  $1.55 million/month  on yearly average @ 7 cents/KwH
