Power plant, also known as power station, is a factory that converts all kinds of primary energy stored in nature into electric energy (secondary energy).

From 65438 to the 1970s, Europe entered the era of power revolution. Not only large enterprises, but also small factories have adopted a new power-electricity. At first, an engine device only supplied power for the lighting of a house or a street. People call this kind of power station a "residential" power station, which generates little electricity. With the growth of power demand, people began to put forward the idea of establishing power production center. With the development of motor manufacturing technology, the expansion of electric energy application scope and the rapid growth of production electricity demand, power plants came into being.
