This In a coal or oil fired power station, the fuel is burned converting its chemical energy into heat and the heat used to convert water into steam at very high temperature and pressure. This then drives a steam turbine, a device which harnesses the energy in the steam heat and pressure to produce rotational movement mechanical energy. The rotating shaft of the steam turbine is coupled to the armature of the alternator, so the final result is electricity. -710 Until recently, methods of generating power have been discussed in the context of large, centralized power plants. However, with technological advancements, there is a trend towards what is known as distributed generation. Distributed generation refers to the placement of individual, smaller sized electric generation units at residential, commercial, and industrial sites of use. These small scale power plants, which are primarily powered by natural gas, operate with small gas turbine or combustion engine units, or natural gas fuel cells.
