AMIATA ENERGIA SPA
Amiata Energia S.p.A. is an Italian joint-stock company registered in Santa Fiora, in the province of Grosseto (Tuscany), under registration number GR103748, with a current registry status of active. External Chamber of Commerce records confirm the same entity under tax identification number 01202930531 and a share capital of €520,000, fully paid up. Zavia’s registry data gives an incorporation year of 1999.
The company holds the concession for the Servizio di Teleriscaldamento Urbano, the urban district-heating service of the Municipality of Santa Fiora. It draws residual geothermal steam from the nearby Bagnore geothermal power plant on Monte Amiata, operated by Enel Green Power — steam no longer suitable for electricity generation — and converts it into hot water above 90°C through vapor-to-water heat exchangers. The heat is distributed through roughly 40 kilometres of underground piping to around 850 connected users across Santa Fiora and the adjoining fractions of Bagnore, Bagnolo and Marroneto, comprising 836 residential properties, 13 public buildings including schools, and one industrial customer, the food producer Grandi Salumifici Italiani.
Amiata Energia S.p.A.’s network is supplied entirely by renewable geothermal heat rather than fossil fuels, reflecting Monte Amiata’s position as one of Italy’s principal geothermal energy areas. Filed company accounts reported revenue of approximately €2.16 million for the 2023 financial year, up from about €1.92 million in 2022, alongside a reported net loss of roughly €170,000 for 2023. Amiata Energia S.p.A. is not listed on any stock exchange. In January 2018, the company set out plans to extend its district-heating network into Santa Fiora’s historic centre, including remote monitoring and control infrastructure based on fibre-optic technology.

Shareholders of Amiata Energia S.p.A.
Zavia’s registry data records two shareholders in Amiata Energia S.p.A. as of 2 August 2026: Veolia Italia S.p.A., holding 80% of the share capital (800,000 of 1,000,000 recorded shares), and the Comune di Santa Fiora (Municipality of Santa Fiora), holding the remaining 20% (200,000 shares). The recorded holdings are proportionate to the company’s reported share capital of €520,000, as stated in an official Gazzetta Ufficiale company notice. Veolia Italia S.p.A. acquired its majority position under its former name, Siram S.p.A., effective 15 January 2018, when Siram — already part of the French Veolia group — became Amiata Energia S.p.A.’s majority shareholder as part of a stated plan to expand the company’s district-heating operations; Siram S.p.A. has since traded under the Veolia Italia S.p.A. name, consistent with the shareholder name on Zavia’s current registry snapshot. No share-class distinctions were disclosed in the sources reviewed.
Ultimate beneficial ownership
No natural-person Ultimate Beneficial Owner is identified for Amiata Energia S.p.A. in the sources reviewed. The Comune di Santa Fiora is a public municipal body rather than a natural person. Veolia Italia S.p.A. is itself a corporate shareholder; publicly available information identifies it as part of the Veolia group, whose ultimate parent, Veolia Environnement SA, is a listed company on Euronext Paris, so no single natural person can be identified as a beneficial owner through that chain without further disclosure below the group’s public holding level.
Data availability
Full: both disclosed shareholders and their percentage holdings are available as of the 2 August 2026 registry snapshot, and the ownership split is corroborated by the company’s officially reported share capital.

Officers
Directors and officers of Amiata Energia S.p.A.
Zavia’s registry data reports that officer information is not available through the applicable jurisdiction’s disclosure channel for Amiata Energia S.p.A. The only officer identified in the sources reviewed for this profile comes from a January 2018 official company announcement by Veolia’s Italian subsidiary Siram (now Veolia Italia S.p.A.), which named Luca Musante, then Siram’s Administrative Director, as President of Amiata Energia S.p.A. at the time Siram became the company’s majority shareholder. No more recent, independently verifiable appointment, resignation or board-composition information for Amiata Energia S.p.A. was located, so this should be treated as historical rather than confirmation of the company’s current leadership.
Data availability
Historical: the only identified officer record dates to a January 2018 company announcement, and Zavia’s registry snapshot separately confirms that current officer filings are not accessible for this jurisdiction. Nationality and country of residence are not disclosed in either source.
