Challenges o interventions on the district heating network and on the The entire production of heat in Torino is granted by high Turin waste-to-energy plant to connect it to the Grugliasco efficiency CHP (Combined Heat and Power) plants allowing network; Torino is a city and an important business and cultural centre in significant environmental benefits. o the start of the authorisation procedures for building the northern Italy. It is the capital city of Piedmont and of the new heat storage systems in the Turin area. Metropolitan City of Turin, and was the first Italian capital from As far as Energy efficiency is concerned: 1861 to 1865. The city is located mainly on the western bank of - replacement of around 110 boilers in municipal buildings in the Po River, in front of Susa Valley, and is surrounded by the Turin; western Alpine arch and hills. The population of the city proper is - energy requalification of buildings, consultancy and 875,698 (31 December 2018). As for heating, currently, ca. 60% of monitoring of energy consumption and the construction of Torino households are heated by district heating owned and Figure 3 - IREN GROUP: Emissions of CO2 avoided (t) from DH micro co-generation and photovoltaic plants for customers; managed by IREN Energia an IREN Group Company. and CHP - installation of highly energy efficient pumps in the main sewage pumping stations with energy-saving monitoring. District heating in Torino A brief description of the DH network is provided below: Commitment to improvement: Environment 1) Torino Nord CCGT Plant: The plant consists of one green field Figure 5 - POLITECNICO These are some of the next DH projects in Torino: CCGT plant completed in 2011. The plant also comprises a 340 - Saturation of the Turin network: The connection of 8 million 5) Martinetto Heat Storage System: the Martinetto Heat Storage MWt supplementary and back-up plant and an innovative hot cubic metres by 2022, which will take the Turin area to a total water accumulation system with a capacity of 5,000 cubic meters. system consists of 6 pressurized tanks for an overall capacity of 3 volume of 64 million cubic metres and lead to the saturation Main data: 5,000 m and up to 300 MWh of energy stored, discharged at a of district heating system capacity. In 2018, approximately 1.1 maximum power of 150 MW. 400 MWel (full electric mode); million cubic metres of volume was connected and 5.2 km of Figure 1 - IREN GROUP Structure 240 MWth (full cogeneration mode); network was laid. Electric efficiency: 56%; Decarbonisation - Torino Nord extension phase 1: The connection of The reduction of climate-changing emissions saw Torino involved The city of Torino started to reduce energy consumption and Overall efficiency: 85%. approximately 5 million cubic meters of district heating in many initiatives in 2018: from highly-efficient renewable replace domestic fossil-based energy use with large cogeneration volume. Phase 1 (2017-2020) will lead to the saturation of the energy production, to systems for reducing the energy plant since 1982. In 1982 AEM (former name of IREN Energia) residual capacity of the district heating system, through the consumption of production processes and the promotion of start to manage a small DH network in one of the city districts optimisation of the storage systems. In 2018, 132,202 million energy efficient services for various target customers. building also a new CHP plant to cover an area of 900.000 m3. In cubic metres were connected and 1.4 km of network was laid. The results of these initiatives have proved significant: compared 1988 AEM built a new CHP Plant and a DH network in another - Torino San Salvario: The extension of the district heating to 2017, IREN Group have reduced the direct energy consumption district - Mirafiori Nord: network and the authorisation procedure to construct a new by 3% and achieved total savings of over 558,000 tonnes of oil heat storage system which will allow around 2.5 million cubic Zone Mm3 Residents served equivalent. CO2 emissions from production processes fell by metres to be connected.

In 2018, works District Heating network. to DH network: began and 1.16 km of network was laid. The developing trend and data at the end of 2018 of the DH - Beinasco district heating: The supply of the Beinasco district network of Turin and surrounding municipalities are as follow: heating network via the connection to the Turin waste-to- km Mm3 Residents served Figure 4 - TORINO NORD energy plant and the interconnection with the Turin network, 2001 241 26,91 285,000 2) Moncalieri CCGTs Plant: the Moncalieri Plant consists of two without the need for new production plants. It is planned to 2010 400 44 410,000 CCGTs, RPW2GT and 3GT, both feeding the Turin DH system. 3GT connect approximately 500,000 cubic metres. In 2018, 2012 500 56 560,000 is a green field plant completed in 2005. RPW2GT, (completed in approximately 3 km of network was laid. 2018 632 68,9 638,082 2009) is a repowering of a cogeneration steam cycle installed in 1966. Main data: Keys to success The mayor targets for Torino in next years are: investments in Our ambition 2 CCGT plants; new connections to the district heating network; creation of new A green city with clean air and a robust economy. An energy 2 x 400 MW (full electric mode); el heat storage; additional investments for the flexibility of heating system based on clean and reliable, available and affordable 2 x 260 MW (full cogeneration mode); th systems to guarantee the best efficiency standards and to energy sources.
