Thermal Power Plant A thermal power station is a power plant in which the prime mover is steam driven.Water is heated,turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.
