in a power station

How are generators used in power stations?

Power stations generate most of the electricity in Ireland. Power stations use a fuel to heat water into high-pressure steam. The steam turns the turbines that run the generators.

Some fuels are easier to use in a power station than others. Fossil-fuels (such as coal, gas and oil) are popular power station fuels as they burn reliably and more can be added to boilers when extra energy is required. They can quickly increase the speed of the turbines and the amount of electricity generated so more electricity is put into the national grid when there is a sudden increase in demand. Nuclear power stations cannot be started and stopped in the same way so they are better for providing a background level of power.
