Dialogue with the urban context for new energy: the Borgo Panigale cogeneration plant When going by the roundabout between Via Prati di Caprara and Via Vittorio Sabena in the Reno di Borgo Panigale neighbourhood in Bologna, it seems like you are passing next to a gigantic colourful radiator. It has the appearance of a modern work of art, but instead it is the Hera Group’s new cogeneration plant. This plant has changed the face of the entire neighbourhood since it was inaugurated in October 2017. Its characteristic element is the elliptical structure covering the stack of the plant. It consists of 576 plates of colourful porcelain stoneware arranged on multiple overlapping rings that create a combination of colours and light with the nuances typical of the city of Bologna: brick red, ochre yellow, tuff yellow, dark brown and rust. brgopanigale.jpg Hera’s undertaking for an efficient district heating system The Cogen plant, which stands in Via Paolo Nanni Costa, is not only Hera’s jewel from the architectural viewpoint - perfectly integrated with the new urban context of the neighbourhood - but is also the Group’s pride and joy from the production viewpoint. Entirely designed and built by Heratech, the engineering essence of the Hera Group, the plant produces energy in cogeneration, meaning both electricity and hot water necessary for the district heating network. Built thanks to an investment topping Euro 17 million, the plant heats the equivalent of 8000 housing units and currently the turbines produce up to 35,000 Mwh of energy a year, almost double that of the past. District heating is already in itself a “sustainable” and eco-friendly supply because it is able to guarantee greater efficiency than the traditional household boilers. What’s more is that the plant guarantees less atmospheric emissions, greater reliability and a higher availability of energy with 90% efficiency. What does all of this mean in terms of benefits for the environment? It is like planting 25,000 new trees every year. Or stopping the flow of traffic of 8000 vehicles during the same period. Technology, efficiency, reutilisation of the land The use of advanced technology and energy efficiency are therefore the cornerstones of this work, in line with Hera’s mission for sustainable development. But that’s not all. The new Cogen district heating plant made a remarkable impact also in terms of land reutilisation. Built on the site of the thermoelectric plant in operation since the 1990s, the Cogen plant allowed the plant in Via Segantini to be shut down and today only one plant is able to cover the same requirement guaranteed by the two of the past. (is it advisable to say that?) Yes, I think so This is an enormous goal that Hera has met, which sets upgrading existing facilities one of its primary objectives. If the percentage of land reutilisation was 77% in the Group Sustainability Report closed in 2019, the development of the network works and of plants presently in progress and included in the 2020-2023 Industrial Plan will allow 73% of reutilised land to be guaranteed. (data updated to 2019). The undertaking of the Hera Group for energy efficiency The Borgo Panigale Cogen plant is part of the 343 interventions forming the plans for improvement of Hera, Inrete, AcegasApsAmga and Marche Multiservizi at year-end 2019, and that will allow consumption to be cut by 13,740 Tep (-5.9% energy consumption compared to 2013), passing the target set for 2020 by -5%. (data updated to 2019). The Bologna Cogen plant in figures: 8,000 housing units served 35,000 Mwh energy produced each year Euro 17 million invested District Heating Our plants no null null

Hergo Reti: the smart approach to emergency service and maintenance hergo reti.jpg More than 130 thousand emergency response reports involving 1,500 employees in 2019. More than 50 thousand emergency response operations in the first six months of 2020, in a local area that includes Emilia-Romagna, Triveneto and Marche. These numbers speak for Hergo Reti, Hera Group's platform that effectively manages our operations, maintenance, technical assistance, and emergency response activities. Efficiency, performance and satisfaction are the key words that have guided us along the development of Hergo Reti, a project included in our Utilities 4.0 plan. Since its introduction in 2018, the "Geocall" IT platform has enabled us to simplify our processes by applying the benefits of digitalisation to emergency response activities. In the past, the persistence of paper documents or data accessible only from a fixed location slowed down operations. The need for constant telephone contact with assistants and the use of multiple devices for different functions did not improve process efficiency. Today, thanks to "Geocall", everything has become accessible via smartphone: from the technical information of the user systems to the data on service personnel, up to the creation and allocation of the work phases, the consultation of multimedia documents attached to the work orders and road navigation to the location of the report. no

Measure to innovate. Hera Luce's tool is ahead of its time Waste can spring back to a new life almost indefinitely. This principle is the foundation of the circular economy. It is based on the five Rs – reduce, reuse, recycle, recover, regenerate – and aims to minimize waste and the use of resources. And this is also the foundation of our front line fight to manage municipal waste, which today, more than ever before, has become a precious resource, thanks to a circular approach. MG_0694.jpg Our efforts have gone well beyond waste management. Since 2017, we have been trying to apply the same circularity to public lighting systems. But to innovate, you have to measure. That's why Hera Luce developed a measurement system to analyse materials used in public lighting throughout their entire life cycle – from origin to final destination – both in terms of material flows and in economic terms (costs/revenues). In 2017, this approach to measuring circularity had already been brought into line with the guidelines of the Italian Ministry of the Environment and it is now consistent with Circulytics, the new digital tool which accurately measures circularity, developed by the Ellen MacArthur Foundation in 2019, and which we were involved in as testers. Our evaluation system also anticipated the requirements of the Italian Ministry of the Environment on the minimum environmental criteria (MEC) for public lighting services. In fact, since 2016, our calls for tenders require MEC compliance and, since 2018, also require the material balance. Our strong focus on circularity and environmental sustainability, the awareness raising process launched with our suppliers, and being forerunners of such a measuring tool have been rewarding choices. Hera Luce has thus been awarded the contracts for the municipalities of Ferrara, Lugo, Tavullia, and Cervia, and has qualified as a partner to the Municipal Administrations as able to promote the issues of sustainable, intelligent and solidarity-based development, favouring the achievement of the objectives of the UN's 2030 Agenda. In the coming years, we will extend the use of the Hera Luce circularity evaluation tool to water connection sites. Hera Luce's efforts to improve the efficiency of public lighting contribute to achieving target 7.3 of the UN's 2030 Agenda. Hera Luce no http://www.heraluce.it/

Waste-to-energy plants: a resource for the circular economy A waste-to-energy plant, in fact, is a plant in which the heat from the combustion of waste is recovered to generate steam, which is then used to produce electricity or for district heating. link to the district heating page termovalorizzatori.jpg Our nine waste-to-energy plants cover a catchment area of over 3 million inhabitants in the provinces of Ferrara, Modena, Bologna, Forlì-Cesena, Rimini, Isernia, Padua, and Trieste and "enhance" the heat produced for the benefit of the local area. How? By generating both electricity, fed into the Italian distribution network, and heat, sent to homes or users in the surrounding area, through a special distribution network. HOW DOES A WASTE-TO-ENERGY PLANT WORK? Watch the video for a quick and simple explanation of the basic operation of a waste-to-energy plant. ARE WASTE-TO-ENERGY PLANTS DANGEROUS? No. These plants are safe, compliant with the regulations, and contribute less than 1% of total emission sources for dioxins, PM10, NOx, and other major air pollutants (ISPRA data). The only waste consists of ash (about 20% by weight of the treated waste) and particulate (about 3% by weight of the treated waste). Ash is generally used for recovery and production of secondary raw materials for the cement industry, while the particulate is stabilised to reduce any potential pollutants and make it suitable for disposal in an authorised plant. Do you want to know more about our waste-to-energy plant emissions? Visit the section on our website. The waste-to-energy plants are subject to constant monitoring and checks conducted by both Herambiente itself and competent agencies. Checks are carried out with the utmost transparency and anyone can verify the results: the main emission parameters are published and updated every half hour on the website www.herambiente.it. Transparency, in fact, has always been a value for Herambiente, since it manages waste and material and energy recovery activities without compromising the quality of the surrounding environment, with the utmost respect for the territory and adopting solutions with the lowest environmental impact. To dispose of the non-recoverable part of the waste and to make good use of the energy obtained to produce electricity and heat. This is the task of a waste-to-energy plant. no

SCART®: the beautiful and useful aspect of waste To transform waste into art and everyday objects to raise awareness and positively influence the mentality of recovery and reuse. scart.jpg This has been the goal of the SCART® project for over 20 years. It is an ecological initiative based on the desire to breathe life back into materials that become waste every day. The result is, sofas, armchairs, tables, chairs, lamps, drawers, games, musical instruments, clothing, and installations, but also scenery for shows and costumes. There are many initiatives at the Italian and international levels under the SCART® brand. From the prestigious conventions with the Academies of Fine Arts of Florence, Bologna and Ravenna which, every year, involve numerous students in seminars and workshops at the Hera Group's facilities in Santa Croce sull'Arno and Pisa, to the creation of costumes and stage components (for example, for Andrea Bocelli's 2012 concert at the Teatro del Silenzio in Lajatico). Also, on the occasion of the 2019 edition of the Barcolana, the historic international sailing regatta held every year in the Gulf of Trieste, the symbolic "Alice" was made from waste: a giant 10 metre long sardine was set up in Piazza dell'Unità, using about 5 thousand bottles and plastic bottles. SCART® is an invitation to reflect on new intelligent, creative, and above all sustainable lifestyles and contributes to achieving targets 12.2, 12.4, 12.5, and 12.8 of the UN’s 2030 Agenda.

Robotics at the service of humankind Will the future belong to machines? That is the main question that arises when dealing with issues such as Robotics and Artificial Intelligence. Two disciplines that have literally revolutionized the way we do our business, radically changing its processes. Robotica.png Predicting the future is not up to us. However, we are certain of one thing: automation processes are the key to increasing the value of the people who work for the Hera Group. Robotics and Artificial Intelligence, in fact, have enabled us to automate all the repetitive and low value-added business processes. By doing so, we can let people have more time for more qualifying activities and enhance their intellectual capacity on processes that generate more value for the company. Thanks to the Robotic & Intelligent Process Automation platform, a project that is part of our Utilities 4.0 plan, we have obtained significant results, speeding up the process and making the operations more reliable in the 7 processes we have started in recent years: the management of the suppliers' DURC (Unified Certificate of Social Security Payments Compliance), the communications between seller and energy distributors, the seller's Order Entry process, the expense reports, the service notices related to waste management services, the work orders to replace meters in the networks and, lastly, the virtual assistant for planning meetings and booking meeting rooms. By introducing dashboards that monitor automated activities, we can act promptly on business processes, continually optimizing productivity and efficiency. The aim is to extend the scope of automated processes to new areas thanks to their continuous technological evolution, for example, with tools such as semantic text interpretation engines and optical character recognition (OCR) systems. The challenge to make our processes smarter and smarter is just beginning.

PSBO: the gentle giant that protects the sea of Rimini Keeping the sea clean and ensuring that it is safe to swim in is a complex undertaking, but it's not impossible. Proof of this is the Rimini Optimised Seawater Protection Plan (Piano di Salvaguardia della Balneazione Ottimizzato - PSBO) Plan, the largest water reclamation project underway in Italy, which we worked on together with the Rimini Municipality and Romagna Acque. A construction site, indeed 14 of them, which are changing the face of a city that, for over 60 years, has been the backdrop for the holidays of millions of tourists, both Italian and foreign. With an investment of Euro 154 million, the project will ensure that swimming will be safe along the entire Rimini coastline, eliminating sewage from all 11 discharges into the sea. Restoring a clean, healthy, and transparent sea for Rimini and the whole local area is an essential step to promote and give a new outlook to the entire community. Indeed, the sea is not only a precious resource that drives the economy: it is the site of our identity. psbo.jpg Kennedy Square, where it all begins The massive work of the PSBO, the gentle giant that protects the sea, all begins under Piazzale Kennedy. In the event of a storm, in fact, the treatment plant cannot withstand the large volume of both sewage and rainwater it receives. In order not to damage the plant and to prevent flooding, the water is discharged into the sea without treatment. The operation causes ban on swimming, thus impacting the environment, public health, and the economy of the area. The PSBO avoids this situation thanks to two tanks as large as 20 Olympic-size pools, located 40 meters below ground. The first tank, with a capacity of 14 thousand cubic metres, collects the water from the first flush of rain, while the second one, with a capacity of 25 thousand cubic metres, is designed for "buffering", i.e. reducing the rainwater drainage sent into the sea. A forced ventilation mechanism, which sends the air sucked in from the tanks to a treatment system based on activated carbon technology, permanently solves the problem of bad odours. With their modern architecture integrated into the city context, the new waterfront terraces in Piazzale Kennedy will "hide" this complex structure. One already opened to the public in July 2019, and the other will be completed by summer 2020. The Santa Giustina wastewater treatment plant, the "heart" of the PSBO Once the water is collected in the tanks, its real journey begins under Piazzale Kennedy: perhaps the most important of the PSBO's activities. The buffering tank, in fact, is connected to a runoff pumping system that can pump 18,000 litres per second or convey it to the Santa Giustina treatment plant. This is the heart of the gentle giant of Rimini, who transforms the water to make it, as famous song says, "blue and clear". Enhanced with a series of measures that have doubled its capacity, the treatment plant is now able to treat all the wastewater, i.e. from domestic and industrial sewage, from the local area of Rimini and the state of San Marino, and serving 560 thousand inhabitants during the summer season. After separating the water from sand and oil, and eliminating the sewage using denitrifying bacteria (organisms that feed on the substances in the sewage), the treatment plant makes the wastewater transparent and clean thanks to microfiltration membranes, a cutting-edge technology that captures microscopic particles such as viruses and bacteria. The main construction sites of the PSBO Let's go through the history of this ambitious project together. The doubling of the Santa Giustina treatment plant started in 2013 and finished in 2015, was the real kick-off of the PSBO project. Its activity, which is the heart of the entire plant, is also closely linked to the conversion of the Marecchiese treatment plant, to buffer the flow rates to Santa Giustina. Another important milestone was achieved in 2014: the beginning of the remodelling of Rimini's sewerage system, which involved the rehabilitation of Rimini Isola, followed by the separation of the sewerage networks of Rimini Nord. The latter, completed in 2020, was a fundamental step for the entire project. It directly involved the residents of the area, who were called upon to connect their discharge to the new sewage water pipes correctly. At the same time, in 2015 we completed the work on the North Backbone, the link between the Santa Giustina and Bellaria treatment plants, and in 2018 the excavation (using microtunneling) of the South Backbone: thanks to the "mole" boring machine, we laid pipelines under natural slopes, or major roads in towns, without requiring extensive excavations. Further measures, such as the Ausa sewage collector, the Mavone floodway channel, and the sewer pumping station in Via Santa Chiara, have significantly reduced the risk of flooding in most areas of the town where this problem frequently occurs. In addition, with the Ausa Canal project, which artificially covers the canal, we have enhanced the water flow rate in the final stretch from the waterfront to the sea when the spillway channels are opened, creating a pleasant path between the waterfront and Piazzale Kennedy that makes even the nearby swimming facilities more attractive. The results we have achieved To date, more than 5 thousand square meters of coastline have been "freed" from swimming bans, and the construction work is now 90% completed. Thanks to sieving and storage treatments, we have also managed to recover over 20 thousand cubic metres of sand to replenish the beaches along the coast: this operation, which we could describe as a real "feeding" of the beaches by adding new sand, makes it possible to counteract the erosion of the coast, abiding by the principles of the circular economy. These achievements, along with all other planned interventions, have led the PSBO to be mentioned in the UN report "SDG Industry Matrix: Energy, Natural Resources & Chemicals" (2017) as a best practice linked to the sustainable development objectives of the UN’s 2030 Global Agenda.

The Forlì remote control technology hub, the heart of Hera To run efficiently, cars need an engine that works optimally. Hera's engine is its Forlì Remote Control Technological Hub. This facility is unique in Italy and among the most advanced in Europe. It controls and monitors more than 6,600 plants and 67 thousand km of networks. telecontrollo_Forlì_FC.jpg Our sophisticated IT system enables us to remotely control the water, sewerage, gas, and district heating distribution networks in real-time, and covers Hera Group's entire service area. It enables us to continuously monitor malfunctions or failures and take direct action on the systems. In a control room of over 400 square meters, a team of 68 professionals controls the networks thanks to 130 monitors, 34 operating stations, and ten process engineering stations. Also, a giant 60 m2 screen enables operators to view networks and plants in real-time, monitoring them also using precise 3D representations, in addition to all the network operating parameters. The control room, the "heart" of Forlì's technological centre, receives over 9 million pieces of information daily through 360 thousand sensors installed throughout the local area. Every day, its operators handle about 8 thousand events or alarms coming from the field, with a broad range of criticality levels. The synergy between networks and the remote control centre is also ensured by the technical call centre, that supports the emergency response service, and handles around 340 thousand incoming calls per year, equal to an average of over 920 per day, and around 150 thousand outgoing calls. Thanks to the information received in real-time and the very detailed graphical representations, our technicians can immediately assess the extent of each report and activate the necessary actions, such as local emergency services.
