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)
  • 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 2,840 MWe (in electricity mode) and over 2,400 MWt of heat production capacity.

In 2017, Iren Group produced around 9,033 GWh of electricity and around 3,000 GWh of heat.

Electricity produced by plants fuelled by environmentally friendly sources (renewable or similar) represents about 86% of the overall production of the Group, compared to the national average which stands at 37%.

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 9 photovoltaic plants for a total installed output of 0.3 MW and electricity production that in 2017 was around 185 MWh. Furthermore there are about 26 GWh produced by Iren Rinnovabili plants.


Electricity distribution: Iren Group, with 7,654 km of networks (high, medium and low voltage), distributes electricity to the cities of Turin, Parma and Vercelli for a total of 853,551 customers. In 2017, it distributed a total of 4,248 GWh of electricity, 3,149 GWh of which in Turin and 915 GWh in Parma and 184 GWh in Vercelli.

Gas distribution: In 2017, the Group distributed around 1,289 million cubic meters of natural gas to 742,327 customers in 91 municipalities through 7,984 km of network in Emilia-Romagna, Liguria and Piedmont.

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 deals with the distribution and sale of LPG. In the Emilian area in particular it does so via 14 delivery plants located in a few mountainous municipalities within the province of Reggio Emilia. The suppliers deliver already odourised LPG in tanks, and the Group distributes it to customers at a pressure of 30 mbar.

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 18,954 km of aqueduct networks, 10,393 km of sewage systems and 1,171 wastewater treatment plants, the Group serves 2,640,754 residents in 242 municipalities in the provinces of La Spezia, Genoa, Imperia, Savona, Parma, Piacenza, Reggio Emilia, Aosta, Asti, Cuneo, Novara, Vercelli, Brescia, Mantua, Pavia and Verona, with 181 million cubic metres sold in 2017.


Iren Mercato is the Group company that operates in the sale of electricity, gas and heat for the district heating of extra-commodity services and products for energy efficiency in particular.

Iren Mercato is present throughout Italy, with a greater concentration of customers in the central-northern areas. The main sources available for Iren Mercato operations are the thermoelectric and hydroelectric plants of the Group.


Sale of Natural Gas

The amount of natural gas procured in 2017 came to approximately 2,872 million cubic metres, of which approximately 1,134 million cubic metres were sold to end customers, 1,530 million cubic metres were used within the Group – for producing electricity and thermal energy, as well as for supplying heating services – whilst 208 million cubic metres of gas remained in storage.

At 31 December 2017, the number of retail gas customers managed by Iren Mercato came to approximately 896,950 (429,150 in the protected market and 467,800 in the free market), distributed mainly across Liguria, Piedmont, the provinces of Parma, Piacenza, Reggio Emilia, Modena and in the Grossetto area.


Sale of Electricity

The volumes of electricity sold in 2017 amounted to 15,921 GWh.

At the end of 2017, the number of retail electricity customers managed came to approximately 820,450 (571,450 on the free market and 249,000 on the protected market), mainly distributed in Turin and Parma where the Group also acts as the “protected market” service operator, and the other areas in which the Group operates.


Sale of Heat for District Heating

Iren Mercato sells thermal energy in the municipalities of Turin, Nichelino, Genoa, Reggio Emilia, Piacenza and Parma. In 2017 the Group served a volume of 87.1 million cubic metres, and over 2,409 GWht of heat were sold. The thermal energy acquired by third parties amounted to approximately 20 GWht.

Environmental Services

The environmental services include the collection and recovery or disposal of solid urban waste or similar and non-hazardous special waste, as well as its transportation to plants belonging to the Group or third parties.

The Group manages environmental health services in the provinces of Piacenza, Parma, Reggio Emilia, Vercelli and in the City of Turin for a total of 145 municipalities, serving 2,096,232 residents.

In 2017, 1,700,000 tonnes of waste were processed, of which approximately 1,208,000 tonnes of urban waste, by means of 18 treatment, selection, storage and recovery plants, 3 waste-to-energy plants (Piacenza, Parma and Turin) and 2 composting plants.

The Group has activated highly structured separated waste collection systems which, partly thanks to the management of 145 equipped ecological stations, have made it possible for the entire area served to achieve results of more than 60% separation.

The non-separated fraction of waste is disposed of in several different ways in order to make the most of it as a resource, reducing the amounts destined for waste-to-energy conversion and disposal in landfills.

The environmental services also include street-cleaning, sweeping of pavements and urban green areas and the clearing of snow.

Technological Services

The Group provides the City of Turin with the management of heating (about 800 buildings) and electric services in municipal buildings and the global technological service for buildings of public interest.

The Group’s telecommunications network extends over the Turin area and from the ridge of the Susa Valley to Susa. Thanks to the possibility of accessing the networks of the Province of Turin and a local consortium, the Group’s network can easily extend to points in the Piedmont provinces and to Milano Caldera, the Italian Internet bandwidth exchange point. Within the City of Turin the optic fibre network extends for almost 200 km and connects over 400 customer sites, including the Group’s main sites where it is used, specifically, to monitor and remote control district heating, electricity distribution, public street lighting and for the data collection system for electricity meters and apartment buildings with district heating.

Various passage points for restricted traffic areas (ZTL), traffic light regulators and the remote control of the water network are also managed through the Group’s network. The network reaches Genoa, Parma, Piacenza and Reggio Emilia, through a redundant 10 Gbps infrastructure dedicated to the Group.
