TOTAL ENERGY CONCEPT: A FACET OF ENERGY MANAGEMENT.

It has been found that generating steam at pressure and temperature in excess of process required and using a steam turbine to generate electricity in the plant itself, is more economical than the use of waste heat recovery boilers and offers attractive incentive to the industries which consume large electric power. This has given rise to what is now known as combined heat power plants, variously also known as the Total Energy System (TES), cogeneration, energy cascading, etc. , a concept which is emerging as an interesting prospect for Indian industries. In short, TES can be defined as one in which different forms of energy required by the system are met to the maximum extent from a single source of energy, so that purchased energy requirements imported into the system are reduced to a minimum. TES offers exceptional economics to large users of electricity through on-site generation of their own electricity. Besides, the system helps to achieve higher efficiencies in the utilization of the total energy content of a source by better generation of heat and mechanical power. The concept can be applied with maximum benefit to all industries which require simultaneously large quantities of steam and electricity.
