In 2018, the district heating plants produced a total of 679.8 GWh of electricity and thermal energy, down 1.1% compared to 2017. Retention of maintenance activities carried out on our plants, the objective of optimising production and network management and the integrated management of the source portfolio allowed savings of 36,495 toe in 2018, slightly down by 954 toe (equal to 2.5% less) compared to 2017. Despite this slight decrease in one of the major systems such as Bologna, for example, a saving of 14% in terms of nitrogen oxides and 7% of tonnes of CO2 emitted was achieved compared to 2017, as the renewable source WTE was used more than traditional boilers.
