The Group's energy plants

While up till now the Hera Group has never defined itself as a producer of electricity, it has nevertheless been involved for some time in projects targeted at the efficient production of both electricity and thermal energy.

The power plants that go to make up the Group's electricity supply chain are aimed at ensuring complete competence as well as a diversified portfolio in the production of electricity.

Industrial cogeneration

Poduction chain monitoring

The Hera Group operates in the Industrial Cogeneration business by installing various plants at large companies.

The term cogeneration means the simultaneous production of various forms of secondary energy (electricity and heat energy) starting from just one source (whether fossil or renewable) implemented in a single integrated system. Heat energy can be used for industrial use or room conditioning (heating, cooling).

Cogeneration is achieved in special thermoelectric power plants where hot process water and/or fumes produced by a prime mover powered by fossil fuel (natural gas, fuel oil, biomasses, etc.) are recovered. Thus we get significant energy savings as compared to the separate production of electricity (via generation in an electricity plant) and heat energy (via a traditional thermal plant).
