Acea (company)

Acea Spa (originally an acronym for Azienda Comunale Elettricità e Acque—Electricity and Water Municipal Utility) is a multiutility operative in the management and development of networks and services in the water, energy and environmental sectors. Originally the city of Rome's provider, the Acea group is the main national operator in the water sector with a catchment area of about 10 million people, and manages integrated water services—aqueduct, sewerage and purification—that span the territories of Rome and Frosinone, as well as their respective provinces. Acea is also present in the regions of Lazio, Tuscany, Umbria, Molise and Campania, is listed on the Borsa Italiana and is part of the FTSE Italia Mid Cap index.

History
Rome’s Municipal Electric company, better known by its Italian acronym AEM (for "Azienda Elettrica Municipale"), was founded in 1909 to provide public and private street lighting. In 1912, AEM opened the Centrale Montemartini, its first thermoelectric power plant through which AEM started selling electricity in Rome.

In 1937, the governor of Rome entrusted the company with building and managing of aqueducts as well as the water distribution network for the city. With the newfound responsibilities, AEM changed its name to AGEA (an acronym for "Azienda Governatoriale Elettricità e Acque", Italian for "Government Electricity and Water Company") before changing it again to its current name Acea in 1945. At the end of World War II, the Centrale Montemartini was the only available power plant still operational because it coincidentally escaped the bombings.

In 1953, the Municipal Council of Rome approved Acea’s plan for self-sufficiency in electricity with the aim of improving the city's water system. For the Rome Olympics in 1960, Acea also took responsibility for the city’s public lighting systems.

In 1964, Acea gained control of Rome’s entire water network on the expiry of the concession to Acqua Pia Antica Marcia for the management of the Marcio Aqueduct.

In 1976, Acea’s plan for hydro-sanitary and street lighting refurbishment was approved within the framework of the redevelopment policy of Rome’s suburbs launched by the Rome Municipality. In 1979, the Peschiera-Capore aqueduct system was completed, which continues to be Rome's main water source.

It was in 1985 that the company completed the management of the water cycle by taking on purification services.

In 1989, Acea changed its name from “Azienda Comunale Elettricità” (Municipal Electricity and Water Agency) to “Azienda Comunale dell’Energia e dell’Ambiente” (Municipal Agency of Energy and the Environment).

In the nineteen eighties and nineties, the Tor di Valle cogeneration plant began operation (in 1984, converted later to combined cycle from 1996) and the EUR water centre was inaugurated (1993).

In 1992, Acea became a Special Agency and, from the first of January, 1998, a Joint Stock Company (Acea S.p.A.) which, with Chief Executive Officer Paolo Cuccia at the helm, made its entrance on the Milan Stock Exchange on the 16th of July the following year.

In 2000, Acea entered the foreign market by constructing and conceding of a water plant in Lima (Peru).

In 2001, Acea acquired the Enel branch responsible for electricity distribution in the metropolitan area of Rome.

In the early 2000s, Acea took over the management of the integrated water service of ATO 3 Sarnese-Vesuviano in Campania, ATO 5 Lazio Meridionale-Frosinone and, for the Tuscan region, ATO 2 (Pisa), ATO 3 (Florence) and ATO 6 Grosseto-Siena through a group of subsidiary companies.

On 12 January 2018, Acea and Open Fiber stipulated an agreement for the development of an ultra-wide band communication network in Rome. In the same year, Acea entered the gas distribution sector.

On 10 July 2019, Acea, the Rome Municipality and the Lazio Region signed the renewal of the concession until 2031 for the management of the Peschiera aqueduct, an agreement made in light of the plan to double its size.
