Energy production

Acea Group is focused on consolidating the generation of green power, with particular reference to photovoltaic sources, in support of the decarbonisation and energy transition processes.

Acea operates in the photovoltaic energy sector with a total installed capacity of approximately 101 MW (data as at 2023)By the end of 2028, we plan to expand our portfolio with around 870 MW (of which 210 already authorized) of installed photovoltaic plant capacity. 

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 110.7 MW, and 7 hydroelectric power plants located in the regions of Lazio and Abruzzo, with a total capacity of 119.3 MW. We also produce energy via two waste-to-energy plants, for an overall electricity output of 62.5 MW.

Our objectives to develop our business

We plan to increase our energy production capacity using renewable sources to support internal consumption and reduce the company’s carbon footprint in observance of SBTi targets.

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. The activities carried out by Ecogena also include the planning and building of cogeneration and trigeneration plants.

The company Acea Produzione manages the production of energy and heat with a power plant consisting of hydroelectric, thermoelectric and photovoltaic systems.

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.
