What’s the Cogeneration

How Cogeneration works

A heat engine coupled with a generator converts the primary energy of the fuel into electricity. The heat generated by the engine cooling circuits and fumes is recovered and used again in the system. A cogeneration plant consists of an endothermic engine, an alternator, and a heat recovery system.
The engine, powered by natural gas (or lpg, diesel oil, biofuel or syngas), drives the alternator generating electricity; at the same time, the heat recovered from the fumes and cooling circuits is used to supply the customer's thermal utilities.


The sizing of the system takes into account the customer's thermal and electrical consumption profiles, and the size of the machine is determined to meet the consumption baseline, avoiding both excessive electricity and production of heat that cannot be used.
Only under those conditions we can speak of maximum energy efficiency and gain real economic and environmental benefit for both the Customer and Cogenext.

Cogenext means:

  • Economic and sustainable development of the project
  • Energy efficiency and environmental protection
  • An effective reduction of energy expenditure, both through the reduction of consumption and through the lower cost of energy-based carriers produced on site by the cogeneration plants

Constantly focused on innovation and customer satisfaction, Cogenext develops further solutions that can increasingly lower the consumption of the production process by utilizing renewable and non-renewable energy sources.
