Total energy produced

 

The figures do not include the production of biomethane at the Sant’Agata Bolognese plant, which totalled 6.5 million cubic metres of biomethane in 2019, corresponding to 59,215 MWh.

The share of energy produced from renewable sources in 2019 was 25.5%, down from the previous year, due to the increase in heat produced by thermal power plants (see the section on thermal energy). The share of energy produced by cogeneration and turboexpanders amounts to 32%. Together, the two categories represent about 58% of the total energy the Group produces.

The figures do not include the production of biomethane at the Sant’Agata Bolognese plant, which totalled 6.5 million cubic metres of biomethane in 2019, corresponding to 59,215 MWh.

In coming years, the Group’s energy production sustainability profile will improve, mainly due to:

  • full operation of the plant mentioned above to produce biomethane from organic waste;
  • the 20% increase by 2023 (compared to 2016-19 average) in the use of geothermal energy for Ferrara’s district heating system, following the award to Hera of the concession for direct operation of geothermal wells.In coming years, there will be a further improvement in the Group’s energy production sustainability profile, mainly due to:
  • full operational start-up in 2019 of the plant mentioned above to produce biomethane from organic waste, in Bologna;
  • the 2.7% increase by 2022 (compared to 2018 values) in the use of geothermal energy for the Ferrara district heating system, following the concession for direct operation of geothermal wells being awarded to Hera.

Below is an outline of the environmental performance of the district heating projects financed or refinanced through the Green Bond issued in July 2014.
