This type of power station has very high energy losses due to great heat loss in the boiler and condensor. the following equation is used to calculate power station efficiency:

Thermal efficiency

the above can be re-written as follows:


The above generally works out to ±30% for steam power stations.

you can further calculate overall efficiency as follows:

the above can be re-written as follows:


The above generally works out to ±29% ( 1% loss at the generator ) for steam power stations.
