What Acea Energia does
Acea Energia (legally Acea S.p.A.) is a publicly listed Italian multi-utility, headquartered in Rome and operating since 1909. It runs an integrated portfolio of network infrastructure and related services through dedicated subsidiaries: water management (a.Acqua), electricity distribution in Rome and Formello (Areti), gas distribution (a.Gas), waste treatment and recovery (a.Ambiente), engineering and laboratory services (a.Infrastructure), resilient infrastructure systems (a.Quantum), electricity production from hydro, thermal, and photovoltaic plants (a.Produzione), and energy sales (Acea Energy Management, divested to Plenitude/Eni in December 2025). The company serves approximately 10 million people with water services, distributes roughly 10 TWh of electricity annually, and manages around 1.6 million tonnes of waste per year, making it Italy's leading water operator by population served.
Acea generates revenue principally through regulated network tariffs administered by ARERA for water, electricity distribution, and gas distribution, supplemented by fees from waste treatment, district heating (A.cities and Acea Produzione), engineering services, and (until the December 2025 divestiture) competitive energy retail. Go-to-market is infrastructure-mediated rather than sales-led: services are delivered through owned physical networks under long-dated concessions, with supplementary digital self-service via the MyAcea portal, ADR conciliation procedures, and education programs (Acea Scuola). Cross-selling and value-added services (monumental fountains such as the Trejan/nasoni, artistic lighting of historical sites including Vatican Museums, and the Piano Mattei Congo water project) leverage the existing regulated footprint.
The company employs 5,001-10,000 staff, is listed on the Milan Stock Exchange (BIT:ACE) within the FTSE MIB index, and operates under a published Sustainability Plan 2024-2028 with ESG ratings and regulatory transparency. Its CEO is Giuseppe Gola. The 2025 Plenitude transaction, valued at up to EUR 587 million for the energy sales arm, narrows the group's competitive perimeter to regulated and quasi-regulated infrastructure while providing capital for reallocation toward regulated capex and selective international expansion.
