Cogeneration is by definition the combined production of electricity / mechanical energy and thermal energy (heat), obtained in special plants using the same primary energy. In this way, fuel energy content is maximized, with a quite high process efficiency. If electricity and thermal energy are simultaneously required by a consumer, instead of installing a boiler and buying electricity from the grid, a cogeneration system producing electric energy and heat at a temperature suitable for the requirements is the solution.

The user can therefore self-consume the electricity or sell it to the Grid, and use the residual heat for heating or for his industrial processes, reaching very high levels of efficiency, with a sensible cost reduction. Restag offers tailored cogeneration systems for customer needs, whether for industrial or agricultural or purely residential use (condominium or homes).
