Energy production

The Group’s power production plants consist mainly of hydroelectric and photovoltaic plants that use renewable sources and combined cycle cogeneration thermoelectric plants, which are some of the most efficient technologies currently available on the market. Furthermore, cogeneration is connected to the urban district heating network, which, compared to traditional heating systems, allows for reductions in energy consumption and improves environmental performance.

In 2021, Iren Group produced 9,823 GWh of electricity, more than 76% from renewable sources (water, solar, biomass or waste) and high efficiency cogeneration.

The significant change in terms of electricity production compared to 2020 is recorded in the contraction of production from thermoelectric power, i.e. from the Turbigo plant, which had recorded exceptional production in 2020. On the thermal energy side, the overall growth of 13% over 2021 is due to increased production from cogeneration plants and waste-to-energy plants.

Producing energy from hydroelectric, photovoltaic and cogeneration plants reduces environmental impact

The objectives of the Strategic Plan to 2030 provide for an increase in installed capacity from renewable sources in order to reach a total capacity of 2.8 GW. To increase the installed power of the hydroelectric plants, the projects for the reactivation of the Noasca (TO) and Giffoni (SA) plants and for the installation of the generator unit at the San Mauro (TO) dam cross-section.

¹ The capacity of the cogeneration plants and waste-to-energy plants refers to the electrical set-up; the capacity of these plants in cogeneration set-up is 1,092 MWe and 62 MWe, respectively.
