Energy distribution

We distribute electricity to households and companies, and we illuminate the Capital's roads and monuments.
We distribute electricity and heating mainly in the metropolitan area of Rome for both private use and public and artistic lighting. In just the Rome area, we distribute 9.4 TWh of electricity and control a public and artistic lighting network comprising 204,676 lighting points and 231,437 lamps, 92% of which are LED lamps.

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

In terms of volume of electricity distributed, approximately 9,400 GWh in 2022, Acea is the third largest Italian operator in the sector.

In 2022, we continued working on an innovative technological solution for the creation of “smart poles” and contributing to the development of smart cities. The project has reached the design and prototype development phase and the equipment production commissioning phase has also been initiated.

Our objectives to develop our business

  • Technological evolution of the network, with the installation of second generation smart meters to develop new services for residents
  • Investments designed to improve network resilience
  • Digitalisation for our infrastructures
  • Advanced automation of the network
  • Projects concerning energy efficiency and the development of new technologies, such as electric mobility and smart grids. With regard to energy flexibility, Acea is taking part in the European “PlatOne” project which aims to develop a technological solution that can optimise the operation and management of electricity networks. Areti has developed the RomeFlex pilot project aimed at creating a market for the flexibility of the electricity grid in the Rome area, extending the tests already underway for the PlatOne project.

2G Digital Meters

From October 2020 Acea, through its company Areti, commenced the project to replace first generation electricity meters with the innovative 2G Smart meter system which allows more accurate measurement and a better and optimised management of the network. The additional 2G smart meters installed by Areti in 2022 totalled 273,294.
