Energy efficiency in public lighting

Three Hera Group companies – Hera Luce, AcegasApsAmga and Marche Multiservizi – manage around 519 thousand light points, guaranteeing the proper operation of the public lighting service in 163 municipalities in nine Regions: Emilia-Romagna, Umbria, Lombardy, Marche, Lazio, Tuscany, Piedmont, Veneto, Friuli Venezia Giulia and Abruzzo. It also manages traffic light installations in some areas for a total of over 11,600 traffic lights. Considering Hera Luce only, the number of light points managed in 2017 rose to 283 thousand (+1.6% compared to 2016).

Energy saving light bulbs (i.e. not mercury-vapour lamps which, according to the energy qualification system developed by Hera Luce on the basis of the Minimum Environmental Criteria, belong to class G) are used at 71% of the light points served, while LED lamps are used at 14%, doubling compared to 2016. Consumption optimization systems (reduction of brightness, partial shutdown, etc.) are used at 51% of the light points operated by Hera Luce.

During 2017, significant effort was made with regard to energy retrofitting and replacement with LED lamps, clearly visible in the growth in percentage terms, which also involved the already efficient sodium light points and explains the percentage reduction of low consumption lamps.

In 2017, the public lighting refurbishment works in the municipalities we serve, replacing incandescent lamps with LED lamps, determined a saving of about 1,300 toe on a yearly basis; energy saving measures are expected for 2018 for further 1,300 toe. In 2014, the Citylight system started operation. The system collects fault reports and data regarding Hera Luce Municipalities; at present, around 70% of the light points managed are visible in the network. The new tools made available for checking consumption (Citylight Energy Management Module) have been approved and are used on a daily basis. The platform is constantly evolving under the guidance of personnel appropriately trained on energy efficiency issues.

Public lighting replacement activities in Modena were completed, with the aim to achieve cost savings without reducing the time public lighting is provided, to improve environmental performance and reduce emissions. In 2017, energy efficiency measures were carried out on the Modena 6-7-8-9 Lots as part of the efficiency project called “Modena Pensa LED”, for a total of over 6,000 light points and estimated savings of over 1.5 million kWh, equal to about 330 toe.

The M’illumino di LED initiative was planned: a project to reduce Hera Group’s energy consumption through energy efficiency measures for the facilities provided with outdoor lighting. The facilities of Bologna and Ravenna will be the first to be involved in the project.

Hera Luce continues the development activities related to various partnerships launched in previous years connected with:

  • update of the minimum environmental criteria for public lighting (MEC PL) and definition of the new MEC Lighting Services, as member of the working group created by the Ministry for the Environment and for Protection of the Land and Sea;
  • developing a lighting device performance monitoring system in line with the MEC criteria, together with the Ministry of the Environment and the Protection of the Sea;
  • the development of models designed to provide local authorities with tools that enable them to understand the process of analysing and assessing energy efficiency activities, obtain information on the activities to undertake for a retrofitting programme, and attain an initial estimate of the costs of the actions and the benefits that can be obtained;
  • analysis of new lighting technologies assessing costs/benefits and future development possibilities in association with various universities;
  • the creation of projects designed to evolve public lighting towards the development of Smart Cities using public lighting infrastructure;
  • development of a project regarding circular economy, with study of a practical case applied to a public lighting plant;
