Cogeneration or combined heat and power (CHP) is the simultaneous conversion of energy

from fuel gas into heat and power. An important feature of CHP is that the surplus heat, that would otherwise be wasted, is captured and used for water or space heating or other industry processes and applications. The main reason for the installation of a CHP system is to cover the electricity and heat

demand of the user, however, demand for both forms of energy is rarely satisfied in full. Cogeneration systems are therefore usually installed parallel to conventional energy installations in order to allow electricity to be drawn from the mains grid in case of shortfalls or fed into the local network in case of surpluses. Cogeneration, as a technology for the efficient use of energy, brings considerable primary energy savings.

In addition, the primary energy savings offered by cogeneration have a lower environmental impact. Conventional electrical generation consumes 3 kWh of fuel energy to produce 1 kWh of electricity, while cogeneration produces the same amount of electricity with only 1.5 kWh. Therefore, cogeneration produces 50 % less pollutants. As a result of the use of surplus heat, the total efficiencies of cogeneration systems reach around 85 %, which implies significant primary energy savings. Economic viability of CHP – with the current ratios between prices for electricity and fuels, cogeneration is one of the most effective and economic ways to reduce energy costs.
