The Steam that is generated in the HeRSiG is sent to the STG or "Steam Turbine Generator". The STG looks very similar to the CTG (Combustion Turbine Generator) in that it has many rotor blades, but no combustion of flammable gas takes place. As the steam moves through the STG the blades rotate and generate electricity by turning a generator on the end of the shaft. The spent steam is sent to a condensator that uses cool water from the cooling towers to turn the steam back into water, and then it is pumped back to the HeRSiG to repeat the process.
Why all this extra fuss to make steam? It's free baby, and free means extra profit, and extra profit means more jobs! Ok maybe the job thing was going a little too far but you never know. The existing plant (units 1 and 2) by comparison, just boiled water to make steam so if you consider the cost of Gas, it makes sense to get all the energy you can out of a product. Like Martha says "It's a good thing".
