In the game water is heated up by the boilers to 100C and leaves the boilers as liquid water. However as the name says steam turbines require steam, so the water should exit the boiler as steam.
Furthermore steam of just 100C at 1 bar cannot be used for power generation in an open cycle like this(water is used from the environment and steam is released to the environment at 1 bar) and in reality it’s heated up by the boilers to a minimum of 400C at 30 bar(in 2014), but this can go up to 585C at 165bar.
So what should change is
- Boiler exit temp: minimal 400C
- Boiler exit substance: Steam
By the way this system is very simplified and is not what is used in reality for power generation. Firstly because you would not use river or lake water in the turbines since it’s polluted and would damage the turbine blades. Secondly you would not throw steam of 100C in the atmosphere, since it still contains energy which can be extracted.
However both these changes would require a closed circuit, which would add multiple elements (condenser, pumps, cooling towers) to the system and therefore will probably be too complicated for the game.
