Cogeneration systems

Cogeneration systems are based on the use of heat. The use of thermal energy avoids major energy losses and provides greater efficiency and economic profitability.

A traditional generator transforms the chemical energy that exists in fossil fuels (diesel, gas, biogas, among others) into electrical energy. Generally, its yield does not exceed 45%, but is somewhere between 35% and 40%. The remainder is released into the atmosphere in the form of exhaust gases.

A cogeneration system, on the other hand, is based on the use of heat, which raises the overall yield of the group to values between 75% and 90%. The use of thermal energy avoids major energy losses and provides greater efficiency and economic profitability to these projects while reducing the emission of toxic gases into the atmosphere.

The generating sets based on this different concept of energy generation naturally present some particularities:

  • are usually oriented to the production of energy in a continuous way (24h/365days);
  • are usually fueled by fuels that optimize operating costs (OPEX), such as natural gas and biogas;
  • for this reason, they must be easily transportable to locations where such fuel sources exist and must be suitable for the surroundings;
  • are capable of withstanding adverse weather conditions;
  • have a variety of extras so that it is possible to maximize their operation.
By focusing on innovation and differentiation of its solutions, namely with the development of cogeneration projects around the world, Grupel has been able to meet the most stringent requirements of its clients.
