      Production wells are drilled down to the aquifer and the superheated pressurized steam (180‒350 °C) is brought to the surface at high speeds, then passed through a steam turbine to generate electricity. In most cases, however, the steam is condensed back into water; it is called a closed cycle.

      A thermal power station is a power station in which heat energy is converted to electricity. Typically, water is heated into steam, which is used to drive an electrical generator. After it passes through the turbine the steam is condensed in a steam condenser and recycled to where it was heated. This is known as a Rankine cycle. The greatest variation in the design of thermal power stations is due to the different …
