Promotion of energy efficiency

More light and less consumption in 14 municipalities

In 2019, work was completed in the municipality of Tortoreto (TE), where almost all the existing lighting points were upgraded with about 3,600 luminaires equipped with LED technology. The works to make the plants compliant and to ensure they are safe include, among other things, the replacement of sections of the power line, for a total of over 11 km. Special attention was paid to the architectural and scenic lighting to highlight the historical and outstanding elements of the municipality, revitalizing the walls along the provincial road near the gate to the fortified town. We expect energy savings of over 70% compared to the initial state of the systems, which means about 350 toe, and a reduction of about 325 tonnes/year of CO2 emissions.

Work has also been completed in Caprino Bergamasco (BG), Madone (BG), Suisio (BS), Marcheno (BS), Sarezzo (BS), Attimis (UD), Mariano del Friuli (GO), Martignacco (UD), Pasian di Prato (UD), Piacenza d’Adige (PD), San Canzian d’Isonzo (GO), Vighizzolo d’Este (PD) and Vivaro (PN), while work began in Longiano (FC), Bernate Ticino (MI), Curno (BG), Carbognano (VT), Paliano (FR), Cervia (RA), Misano Adriatico (RN), Boltiere (BG), Pedrengo (bg), Roncofreddo (FC), Lugo (RA), Romans d’Isonzo (GO) and Padua in the Arcella district.

The work carried out in 2019 will save 5,124,000 kWh of electricity every year, amounting to 958 tonnes of oil equivalent. Considering as 2,700 kWh per year the average electricity consumption of a household of four people, the amount of energy that will be saved each year with the measures implemented by Hera Luce in 2019 is equal to the annual consumption of 1,898 households.

In 2019, Hera Luce was awarded the contract for the assignment and management of the works to improve the efficiency of public lighting systems in the municipalities of Paliano (FR), Cervia (RA), Boltiere (BG), Pedrengo (BG), Roncofreddo (FC), Lugo (RA), Tavullia (PS), Endine Gaiano (BG), Roncadelle (BS), Torre de’ Busi (BG), Ferrara (FE), Orgosolo (NU), Valtopina (PG) and Ovindoli (AQ).

Hera Luce’s work to improve the efficiency of public lighting contributes to achieving target 7.3 of the UN’s 2030 Agenda.


Energy consumption: -18% in Modena

The contract entered into by the Hera Group and the municipality of Modena is an important example of an energy supply contract, awarded to the Group as a result of a European public tender, competing with some of the leading companies in the industry.

The Hera Group, which partnered in the tender with AcegasApsAmga Servizi Energetici committed to providing significant results to the municipality in terms of energy efficiency improvement, to be achieved through both management improvements and energy renovation measures.

In particular, Hera Group’s offer included an 18% reduction of thermal energy consumption compared to the past (based on the average of the last five years) for the buildings included in the scope of the contract, and also planned to improve this performance by a further 10% due to energy efficiency improvement measures which will involve investments of Euro seven million in the initial years of the contract.

From the systems engineering point of view, the most significant investments concern implementing energy renovation measures for the thermal power plants, installing thermostatic valves on radiators, replacing burners, building solar thermal and photovoltaic plants, renovating lighting systems by installing LED lamps. “Passive” measures to limit heat dispersion from buildings also play an important role, including installing vertical cladding insulation on 12 buildings and insulating the roofs of 10 others.

In the start-up phase of the contract, since the plant upgrading work had not yet been carried out, the efficiency objectives were pursued by giving special attention to the management aspects of the service. From the very first year, this made it possible to reach and exceed the contractual target of 18% saving compared to the tender baseline. The management efficiencies have enabled us to approach 25%.

In 2019, an initial, significant part of the measures was carried out (approximately Euro 5.8 million out of the Euro 7 planned), both for plant upgrading and for “passive” measures, and their completion is expected in 2020. 

The energy efficiency measures required by the Modena heat management contract, contribute to achieving target 7.3 of the UN’s 2030 Agenda.


An annual report on energy saving

In the fifth edition of the “Value to Energy” report, published in July 2019 (on 2018 data), the Hera Group reported to its stakeholders the results it had achieved over the last eleven years, in terms of energy efficiency. Verified by an independent certification body, the report examines all the aspects of the multiutility’s commitment to saving and efficiently using energy, in the name of environmental and economic sustainability, in the interests of the area it serves and of its over four million customers.

Between 2007 and 2020, 635 projects have been completed and are planned that have and will enable the Group to save energy (108 were completed in 2018), saving approximately 891 thousand toe (tonnes of oil equivalent), corresponding to the annual consumption of 625 thousand households, and avoiding 1.7 million tonnes of CO2, equivalent to approximately 1.3 million fewer cars on the road for a year (travelling 10 thousand km).

Decarbonisation is crucial to fight climate change. This is the direction taken by both our energy efficiency measures and the other projects to promote the production of energy from renewable sources explained in the “Value to energy” report.

Energy efficiency has always been a fundamental objective for Hera Group, as we are committed to constantly seek and develop innovative solutions for both process control systems and plants. Energy efficiency is also considered the “fifth fuel”: the cheapest, with the greatest environmental benefit and one that can be generated by everyone, every day. Hera’s commitment on this front is shown by its results and also by Hera being given the CESEF Energy Efficiency Award, for 2018.

The publishing of the “Value to energy” report contributes to achieving target 12.8 of the UN’s 2030 Agenda.
