Energy efficiency in public lighting

Three Hera Group companies – Hera Luce, AcegasApsAmga and Marche Multiservizi – manage around 534 thousand light points (+3% compared 2017), guaranteeing the proper operation of the public lighting service in 176 municipalities in ten 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 10,500 traffic lights.

In 15% of light points operated LED lamps are now used, up compared to 2017. Consumption optimization systems (reduction of brightness, partial switching off, etc.) are used at 51% of the light points operated by Hera Luce. 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 35% of the light points served.

During 2018, Hera Luce’s commercial effort aimed at consolidating the territory it serves and expanding its area of influence, offering potential customers smart solutions for their respective cities. Among these proposals, the commitment to energy efficiency achieved by installing low-consumption systems and, above all, latest-technology LEDs, is particularly important.

The 2016 and 2017 data for the percentage of energy-efficient light points were recalculated on the basis of the calculation criteria used in 2018.

In 2018 Hera Luce was finalizing many Public Private Partnership (PPP) projects using Project Financing ex. art. 183(15) of Legislative Decree 50/2016. The projects presented include the energy renovation and implementation of safety measures for public lighting systems, to comply with the Minimum Environmental Criteria for lighting devices (Criteri Ambientali Minimi per l’Illuminazione Pubblica – CAM IP) which came into force in 2017, and for the public lighting service – which came into force in 2018. Among the criteria used to award the contracts, references to the circular economy and to presenting the material balance are increasingly frequent. In this context, Hera Luce carried out the first national and European case study of circular economy applied to public lighting.

During 2018, the work started in 2017 in 7 municipalities was completed and work started in a further 12 municipalities, of which 2 were also completed. Overall, the measures carried out in 2018 will allow a saving of 8,739,000 kWh of electricity each year, corresponding to 1,634 tonnes of oil equivalent (toe). Considering an average electricity consumption of a household of four people equal to 2,700 kWh per year, the amount of energy that will be saved each year with the measures implemented by Hera Luce in 2018 is equal to the annual consumption of 3,237 households. Lower electricity consumption results in over 3,500 tonnes of carbon dioxide emissions being avoided each year.

Particular attention has also been paid to the energy renovation of Hera Group’s offices: efficiency measures have been carried out at the Viale Berti Pichat headquarters in Bologna – including the spectacular lighting of the gasometer – and at the Ravenna headquarters.

Hera Luce continues the development activities related to various actions and partnerships launched in previous years related to:

  • update of the minimum environmental criteria for public lighting (MEC PL) and definition of the new MEC Lighting Services, as a member of the working group created by the Ministry of the Environment, Land and Sea;
  • dissemination of the culture of light;
  • developing a lighting device performance monitoring system in line with the MEC, together with the Ministry of the Environment, Land and 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 improvement activities, obtain information on the activities to undertake for an energy renovation programme, and attain an initial estimate of the costs of the measures and the benefits that can be obtained;
  • analysis of new lighting technologies, assessing costs/benefits and future development options, in association with several universities;
  • the creation of projects designed to evolve public lighting towards the development of Smart Cities using the public lighting infrastructure;
  • development of a circular economy project, studying a practical case applied to a public lighting plant;
