I believe most large coal and nuclear power plants have 2 to 5 generators, nowhere near as many as a wind farm. Also, all of the generators share the boiler and other equipment in common. If something goes wrong with the boiler, or if it has to be taken down for maintenance, the whole plant goes down. - Jed I was heavily involved with power station design from 1970 to 1983 for oil fired, coal fired and nuclear. I have never encountered a design where multiple turbine generators share a common boiler or reactor. That configuration must be quite rare. Each unit in a typical power station shares very little in common beyond the fuel supply and switch yard, although low pressure aux steam and compressed air would be distributed station wide. Any combination of units can be taken down for servicing while the other units remain fully operational. This is a crucial design consideration in any power station.
