Agreed,

I was assuming the turbines outside room, or water cooled as you say. The
losses I was thinking of were electrical, which are much easier to
determine.
In addition, if the plant has not yet been built, then similar plants
electrical output levels compared to rated capacity would give a reasonable
guess at actual production and so heat gains.

One further thought you should take into consideration:

Since you write, it is a 'hydroelectric' plant, most of the produced heat
(losses 
of the turbine and the electric generator) will be in the water flowing
through 
the turbine. So only a fraction of the produced heat will really heat up the

machine room...

Bernhard
