Our "Energy infrastructure" business area distributes the power supply and heating mainly in the metropolitan area of Rome for private use and public and artistic lighting. In just the Rome area, we distribute approximately 10 TWh of electricity to over 1.6 million delivery points and control a public and artistic lighting network of almost 200,000 lighting points.

We constantly focus on reducing our environmental impact: we are committed to energy efficiency projects and the development of new technologies - from LED lamps, smart grid projects and electrical mobility to renewable energy plants - which reduce the light pollution and CO2 emissions of our businesses and services.

We produce electricity mainly via 7 hydroelectric power plants, located in the regions of Lazio and Abruzzo, with an overall capacity of 122 MW, and 2 thermoelectric plants (Montemartini and Tor di Valle) situated in the Municipality of Rome, with a total installed power of 97.3 MW. We are also present in the photovoltaic sector with a total installed capacity of about 37MWp and, through Acea Ambiente, generate energy via two waste-to-energy plants, for an overall gross electricity output of 58MWe.
