What is cogeneration?
Combined Heat and Power
Cogeneration (Combined Heat and Power or CHP) is the simultaneous production of electricity and heat, both of which are used. The central and most fundamental principle of cogeneration is that, in order to maximize the many benefits that arise from it, systems should be based on the heat demand of the application. This can be an individual building, an industrial factory or a town/city served by district heat/cooling. Through the utilization of the heat, the efficiency of a cogeneration plant can reach 80% or more.
Cogeneration optimizes the energy supply to all types of consumers, with the following benefits for both users and society at large:
- Increased efficiency of energy conversion and use. Cogeneration is the most effective and efficient form of power generation.
- Lower emissions to the environment, in particular of CO2, the main greenhouse Cogeneration is the single biggest solution to the Kyoto targets.
- Large cost savings, providing additional competitiveness for industrial and commercial users, and offering affordable heat for domestic users.
- An opportunity to move towards more decentralized forms of electricity generation, where plants are designed to meet the needs of local consumers, providing high efficiency, avoiding transmission losses and increasing flexibility of system use. This will particularly be the case if natural gas is the energy carrier.
- Improved local and general security of supply – local generation, through cogeneration, can reduce the risk of consumers being left without supplies of electricity and/or heating. In addition, the reduced need for fuel resulting from cogeneration reduces import dependency – helping to tackle a key challenge for Turkey’s energy future.
- An opportunity to increase the diversity of generation plant, and provide competition in generation. Cogeneration provides one of the most important vehicles for promoting energy market liberalization.
- Increased employment – a number of studies have now concluded that the development of CHP systems is a generator of jobs.
