In electric power generation using high temperatures (typically by burning fuels), a large portion of the heat is rejected at a lower temperature.
In major power plants the residual heat is utilized for the production of steam, which is then used to produce additional electric power (Combined Cycle) or, if the temperature of this residual heat is too low, having a low thermodynamic value, it is rejected into the sea or to the air near the power plant. In contrast, a private power plant (producing both electricity and thermal power), which is a consumer of both heat and electricity, can make use of the residual heat and substantially increase the overall energy efficiency of the primary heat source.
Cogeneration is not only in the interest of the private producerconsumer, but also for the national economy, and the state encourages such projects.
The Samuel Neaman Institute Energy Forum calls to organize the regulation and encourage the use of the residual heat in co-generation
