Energy production

The 2020-2024 Business Plan is focused on consolidating the generation of green power, with particular reference to photovoltaic sources, in support of the decarbonisation and energy transition processes. Today, we operate in the photovoltaic energy sector (link alla pagina “Photovoltaic plants”) with a total installed capacity of approximately  52 MWp.

By the end of 2024, we plan to expand our portfolio with around 747 MW of installed photovoltaic plant capacity, of which 569 MW from greenfield development in industrial and agricultural areas and 178 MW from M&A transactions. When fully operational, the new facilities will have an annual output of over 1.3 TWh, corresponding to approximately 600 kt of avoided CO2 emissions.

We generate electricity also via 2 thermoelectric power plants (Montemartini and Tor di Valle) located in the municipal area of Rome, with an overall installed capacity of 97.3 MWe, and 7 hydroelectric power plants located in the regions of Lazio and Abruzzo, with a total capacity of 122 MW. We also produce energy via two waste-to-energy plants, for an overall electricity output of 58MWe.

In January 2020 we completed the renovation and upgrading works on the hydroelectric power plants, the last of which concerned the Galileo Ferraris hydroelectric power facility in Mandela, in the province of Rome. This made it possible to optimise the use of available water resources, subject to equal conditions in terms of installed capacity. Moreover, at the Tor di Valle thermoelectric power plant we commenced the installation of another two internal combustion engines which will be fuelled by biogas from Acea Ato 2’s Roma Sud treatment plant. Lastly, again at the same power plant, the construction of a 267.3 kWp photovoltaic power facility was authorised.

The company Ecogena develops energy efficiency initiatives for the Group and reports their results to the Gestore dei Servizi Energetici (GSE) for the awarding of Energy Efficiency Certificates (EECs). The activities assigned to Ecogena also include the design and building of trigeneration plants for the production, in combined mode, of electricity, heat and cold.

Cogeneration and trigeneration

Cogeneration, namely the combined production of electrical and thermal energy, allows high efficiencies to be achieved, between 80% and 90%. Trigeneration, which is a special application of cogeneration, allows use of a part of the thermal energy recovered in order to produce cooling energy in the form of cooled water for air conditioning in rooms or for industrial processes.
