Besides operating in the production of electricity and heat, the Enel Group also operates worldwide in electricity distribution, the storage and movement of fuel, and work in mines and on worksites, while constantly monitoring any environmental impacts from such activities (see the chapter “Quality for customers”).
In order to safeguard the countryside and local area, Enel Infrastructure and Networks adopts specific strategies to mitigate the environmental impacts of building new networks and modernize the exisiting ones. In particular two actions are important for the “cabling” of the networks:
- adoption of elicord cabling consisting of three insulated and intertwined cables;
- underground low and medium voltage lines, in urbanized areas.
The adoption of elicords for overhead lines is, for example, less impactful in crossing woods since it drastically reduces the interventions needed in the area of installation (cutting of plants, etc.), and integrates in terms of the landscape with the vegetation and, by needing a smaller clearance area, reduces the impact on the local area.
The cabling rate was 72% in 2016, up by 4% compared to 2015, and is the percentage of cabled lines to total lines and provides an immediate indication of the reductionof the environmental impact of the transmission lines.The increase in this figure over time is due to an increase in the length of overhead and underground lines at the expense of the bare lines. This is due not only to the systematic introduction of LV overhead lines and the ongoing replacement of the bare LV cables with overhead/underground cables which have been in use for some time now, but also to the adoption of overhead MV lines, with benefits in terms of the resilience of the network, containment of the cutting of plants and a drastic reduction in the risk of electrocution of birds. For this rate, the target is 74% in 2019 (see the chapter “Quality for customers”)
Storage and movement of fuel
In relation to the storage and movement of liquid fuel (storage tanks for oil and diesel and the related oil pipelines) and solid fuel (storage facilities for coal and lignite situated at dedicated ports), particular monitoring is made of the use of resources, the consumption of primary energy, the consumption of electricity and the production of emissions, effluents and waste.
In 2016 there was no mining undertaken in mines owned by the Company, but the activities for geomorphologic, hydrogeological and natural recovery were monitored.
The Enel Group also operates in the work to design, build and revamp plant. The strategies aim to use the best available technologies internationally, in order to guarantee technological development and increase the efficiency of plant, also through suitable and innovative research projects.
As from 2013, in conformity with the new standards, which are applicable as from 2015 and have been defined by the Global Reporting Initiative GRI-G4, the Enel Group started to report the main environmental performance indicators connected to the activities on worksites, which are subject to considerable variety over the years, as regards environmental aspects which are directly managed by the Group.
As from 2016 the reporting has been developed on the basis of a new model of the sustainable worksite and on the principles of the “circular economy” both for worksites relating to thermoelectric power plants and those regarding the construction of new capacity from wind, solar and geothermal renewables sources and from distribution. The model and the first results obtained will be reported in the next Sustainability Report.
