Thermal efficiency is defined as the ratio of heat equivalent mechanical energy available at the turbine to the heat energy available at the combustion of coal in the boiler. The thermal efficiency of the thermal power plants is 30% approx. Most of the heat energy (approx. 50%) is wasted in the condenser.

Through cables, power is transferred from the generator to a nearby transformer. Stepup transformer: While moving through wires, electricity loses part of its power; highvoltage electricity does so at a lower rate than lowvoltage energy. As a result, the voltage of the electricity is "stepped up" or "boosted" as it exits the power plant.
