Acquirente Unico

What Acquirente Unico does

Acquirente Unico S.p.A. is an Italian state-owned enterprise, wholly owned by Gestore dei Servizi Energetici (GSE S.p.A.), which is itself 100% controlled by the Italian Ministry of Economy and Finance (MEF). Established under Article 4 of Legislative Decree 79/99 and operating with a registered share capital of €7,500,000, the company is headquartered in Rome and serves as the sole authorized single-buyer of electricity for Italian consumers who have not elected a competitive market supplier — the so-called Servizio di Maggior Tutela (Greater Protection Service). It procures electricity through auctions and Power Purchase Agreements (PPAs), passes the resulting volumes through ARERA-regulated tariffs, and publishes quarterly reference economic conditions.

Its service portfolio combines regulated procurement, national infrastructure operations, and consumer-facing digital tools. On the infrastructure side, Acquirente Unico operates the Sistema Informativo Integrato (SII), the central data system governing Italian energy market data flows and retail processes, and acts as the Organismo Centrale di Stoccato Unico Italiano (OCSIT), the Italian implementation of EU Directive 2009/119/EC mandating national petroleum product reserves for energy security. On the consumer side, it runs Portale Offerte (a free, transparent retail offer comparison portal), Portale Consumi (consumption monitoring and contract verification) and the Sportello (physical/phone consumer assistance plus free dispute resolution via the Conciliazione process). Additional offerings include the FTE (Fondo per la Transizione Energetica nel Settore Industriale) for industrial decarbonization financing and a public procurement portal.

Revenue mechanics are dominated by regulated, non-commercial flows: contribution fees established by ministerial decree (D.M. 19/04/2013), tariff-approved operating budgets set by ARERA, OCSIT financing via EU tenders and bond issuances (including a 7-year bond launched in 2026), and bond market access. Pricing is not publicly disclosed because the entity operates under regulated tariffs. Its 101-250 headcount serves a captive national customer base of residential and small-business consumers still in regulated supply, alongside industrial clients accessing the FTE and a strategic relationship with ARERA, MASE, MEF, GSE, and EU institutions.

Others

• Bundesnetzagentur: Bundesnetzagentur is Germany's federal energy regulator, with responsibility over electricity and gas markets including oversight of default supply mechanisms similar to Maggior Tutela. Comparable as a European comparator on regulatory architecture for retail energy procurement and consumer protection rather than a commercial competitor.

Regional players

• A2A S.p.A. A2A is a large Italian multi-utility operating across generation, distribution, and retail electricity and gas in northern Italy. Comparable as an Italian regulated utility with retail energy supply, energy transition projects, and exposure to ARERA-regulated economic conditions.
• Iren Group: Iren is a major Italian multi-utility serving electricity, gas, and district heating across northern Italian territories. Comparable as an Italian integrated retail energy utility that interacts with the Maggior Tutela regime and competes in the same regulated and free-market segments.
• Hera S.p.A. Hera is an Italian multi-utility with retail electricity, gas, and waste operations concentrated in Emilia-Romagna and surrounding regions. Comparable as a regulated Italian retail energy utility interacting with the same consumer protection and procurement framework overseen by ARERA.

Broad incumbents

• Edison S.p.A. Edison is one of Italy's largest integrated electricity and gas retailers and historically a major participant in PPA auctions and regulated energy procurement. Comparable as an Italian retail energy operator with deep exposure to regulated procurement mechanisms and PPAs.
• Enel Energia (Enel Group): Enel Energia is Italy's largest competitive retail electricity supplier and historically the dominant counterparty for the Maggior Tutela default customers that Acquirente Unico procures for.

Comparable as a state-influenced regulated utility infrastructure operator that processes the physical and data flows of the Italian electricity system, similar to how Acquirente Unico processes retail procurement and data flows.

Direct peers

• GSE - Gestore dei Servizi Energetici: GSE is the immediate parent company of Acquirente Unico and serves as Italy's state-owned energy services manager under Legislative Decree 79/99.
