CSR of services

Quality in services and customer satisfaction are the pillars on which the Group’s strategy for the years to come is based, together with the objective of acting for the protection and enhancement of the territories it operates in.

For these reasons the Group has chosen to:

  • produce electricity mainly from environmentally friendly sources (renewable or similar): hydroelectric and photovoltaic plants, cogeneration and waste-to-energy plants
  • reduce emissions thanks to the development of district heating through cogeneration and waste-to-energy plants
  • reduce energy and water consumption also through sustainable educational programs for customers
  • promote a rational and sustainable water management operating to reduce leaks in aqueduct networks and investing in sewage and wastewater treatment plants
  • improve integrated waste management systems to increase separated waste collection and energy and material recovery from waste  (circular economy).

Electricity Production and District Heating

Iren Group’s installed capacity totals over 2,850 MWe (in electricity mode) and over 2,490 MWt of heat production capacity.

In 2018, Iren Group produced around 9,002 GWh of electricity and around 2,932 GWh of heat.

Electricity produced by plants fuelled by environmentally friendly sources (renewable or similar) represents about 87% of the overall production of the Group, compared to the national average which stands at 35%.

Plants fuelled by environmentally friendly sources account for about 70% of the total and play an important role in protecting the environment, reducing the emission of pollutants and the use of other forms of production with a higher environmental impact.

Iren has 95 photovoltaic plants for a total installed output of 17.9 MW and electricity production that in 2018 was around 20,227 MWh.

The use of innovative technologies for laying and maintaining the networks means that ordinary maintenance can be performed while reducing time frames and costs, and limiting inconvenience to residents to a minimum. Iren Group also manages the distribution and sale of LPG. In the Reggio Emilia area and the Province of Genoa in particular, via 14 and 7 storage plants respectively, located in various towns within the Municipalities that are still not reached by the natural gas network. The LPG distribution activity is closely connected to the gradual “methanisation” of the area.

Integrated water service: The integrated water service includes the procurement and distribution of drinking water, management of the sewage systems and wastewater treatment activities. With 23,360 km of aqueduct networks, 11,162 km of sewage systems and 1,323 wastewater treatment plants, the Group serves 2,829,798 residents in 265 municipalities in the provinces of La Spezia, Genoa, Imperia, Savona, Parma, Piacenza, Reggio Emilia, Aosta, Alessandria, Asti, Cuneo, Novara, Vercelli, Brescia, Mantua, Pavia and Verona, with 187 million cubic metres sold in 2018.
