Power plants work with ac generators called alternators, which are rotating machines driven by different forms of mechanical engine.
The conventional power plant uses a heat engine, usually a turbine, driven by steam or gas. When steam is used it is produced in a boiler from pure water heated by a fuel, usually coal or oil.
Hydro-electric power plants drive the alternators with an engine driven by the power of falling water. Wind power plants use the wind to turn the generators.
On a power grid, all the machines run synchronously, which means they all turn at the same speed, which is 3000 rpm for a 50 Hz power system. Small generators might turn at a submultiple like 1500 rpm.
Solar power plants do not use rotating machines but generate direct current from the Sun's rays. The power is then converted to AC in an inverter. The conversion process adapts itself to the basic frequency of the grid, which means in practice that solar power must be limited to a relatively low level to avoid causing instability in the grid.

Is it a good idea to have a Power Station in Ireland?
Ireland has many power stations, but no nuclear ones, which you may be referring to. There are risks associated with nuclear power stations and to date Ireland does not have one. Power in power stations is generated by peat, wind and water, amongst other things.
Is there electricity in Zambia?
There is electricity in much of the urban areas of Zambia. Hydro power is provided from the power stations at Kariba North, Victoria Falls and Kafue. Many rural parts of the country run on diesel power stations and many are now coming onto solar power.
Why are so many power stations located on the coast?
Power stations need to use water for cooling. Lakes, rivers and coastal areas are a ready source of water.
