Electricity is induced to flow in a conductor by a changing magnetic field. The faster the magnetic field changes, the greater the induced Voltage. Reversing the direction of the change reverses the direction of the electricity.
Generators and alternators are devices designed to do this continuously and (hopefully) efficiently.
The energy to change the magnetic field comes from the mechanical motion of a flow of some other type of energy typically falling water or expanding steam.
A power plant houses these devices, their control systems and the terminals points of their source and distribution subsystems.
