What Zilio Group does

Zilio Group is a family-owned Italian industrial holding company founded in 1959, headquartered in the Bassano del Grappa / Cassolnovo area of Northern Italy. The group operates across renewable energy and environmental engineering verticals — photovoltaic systems, hydroelectric power generation, water treatment (with proprietary technology for boron and arsenic removal), and biogas — and is led by CEO Damiano Zilio under an Srl Unipersonale (single-member limited liability company) structure. Its customer base is a mix of public-sector and private industrial buyers, including municipalities (e.g., Comune di Petilia Policastro), public utilities and consortia (ASA Spa, Consorzio di Bonifica Ionio Crotonese), and industrial operators (Krunos, Residence Venezia).

The company's technical capabilities span engineering, procurement, and construction (EPC) for renewable energy infrastructure, with specific proprietary processes in water purification and a 92.9% recovery rate cited for its photovoltaic module recycling operations. It is constructing a €12 million PV module recycling plant (groundbreaking March 2023), backed by a €4.5 million PNRR (Italian National Recovery and Resilience Plan) grant, and has commissioned multiple hydroelectric assets including the Torrino Foresta plant (May 2023) and the three-turbine Petilia Policastro project (2020, with Krunos). Operations span five Italian cities with a recently opened Wrocław, Poland office marking its first international footprint.

The business model is project-based, with revenue generated through EPC contracts, technology licensing (notably the boron/arsenic removal process), and recurring maintenance and operations services. The company has announced plans to introduce a "Pay-per-Use" pricing model and an autoconsumo (self-consumption) offering, signalling a shift toward recurring or service-based revenue, alongside plans for a technology hub in Northeast Italy focused on engineering talent development. Disclosed financials are limited; revenue is described qualitatively as "millions of euros in 2022," and headcount is reported at 11-50 employees, with a separate scale commentary referencing "over 1,000 across the group" — the latter likely reflecting project-based contractors rather than core FTE.

Revenue model

1. EPC Contracting: Engineering, Procurement and Construction services for photovoltaic and hydroelectric plants under fixed-price turnkey contracts. The company serves as sole contractor managing all phases from site scouting and feasibility studies through authorization processes, mechanical and electrical design, component procurement, construction, testing, and commissioning.
2. Pay-per-Use Photovoltaic: Zero-initial-investment photovoltaic solutions where clients pay a fixed quota for energy consumed. Zilio Group designs, constructs and maintains plants while clients benefit from energy savings without capital outlay.
3. Financial Advisory Services: Technical, financial and legislative support for renewable energy investments including portfolio analysis, economic and commercial evaluation, and asset valorization. Transformation of distressed assets into upside opportunities.
4. Real Estate Development: Property development and renovation projects including residential construction and demolition/reconstruction services.
5. Water Treatment Plant Construction: Design and construction of water potabilization plants including verification and maintenance services for municipal and industrial water treatment.

Core offering

Zilio Group is an industrial holding that designs, builds, and installs photovoltaic, hydroelectric, drinking water (potabilization), and biogas installations on a turnkey EPC basis, primarily for municipalities, multiutilities, agricultural consortia, and industrial enterprises in Italy and Europe. The group also offers a Pay-per-Use photovoltaic model with zero client capital outlay, financial advisory and due-diligence services for renewable energy investments, and is developing a 12-million-euro photovoltaic module recycling facility.

Product overview

Zilio Group is an industrial holding founded in 1959 operating in renewable energy and environmental sectors. The company offers a comprehensive portfolio centered on three core products: Photovoltaic Systems (utility-scale installations via Pay-per-Use and EPC models), Hydroelectric Power Plants (mini/micro installations and revamping), and Water Treatment (potabilization for boron/arsenic removal). Supporting divisions include Finance (technical/financial support for energy investments), Engineering (Due Diligence services), Innovation (R&D for new projects and patents), Self-Consumption solutions, and Real Estate development. The company recently launched a photovoltaic module recycling plant as part of its circular economy strategy.

Broad incumbents

• Voith Hydro: Global manufacturer and servicer of hydroelectric turbines and generators (including Francis and Pelton machines, which Zilio specifies). Comparable as the upstream equipment counterpart for Zilio's mini/micro hydroelectric EPC work.
• ANDRITZ: International plant equipment manufacturer with a leading hydroelectric turbines and generators business. Comparable as a large incumbent supplier and revamp partner relevant to Zilio's hydro EPC and revamping projects.
• BayWa r.e. Large European renewable energy developer, EPC contractor, and operator with global PV, wind, and bioenergy presence. Comparable as a full-lifecycle renewable EPC and operations counterpart, though substantially larger and more geographically diversified than Zilio.
• Veolia: Global environmental services leader with large water treatment, potabilization, and resource recovery operations. Comparable in Zilio's Environment / water treatment division as a large incumbent in municipal and industrial water infrastructure.
• Enel Green Power: Italy-headquartered global renewable energy developer and operator with utility-scale PV, wind, hydroelectric, and geothermal assets. Comparable across all of Zilio's renewable generation lines at a vastly larger scale, and a key competitor for Italian EPC and asset ownership opportunities.
• Sonnedix: Global solar developer, owner, and operator with significant Italian and European PV portfolio. Comparable in PV power generation and operations focus; offers a scaled benchmark for Zilio's Pay-per-Use-style asset ownership ambitions.
• Suez: International water and waste management group with extensive water treatment and circular economy operations. Overlaps with Zilio's water potabilization and PV recycling businesses as a much larger global benchmark.

Emerging players

• ROSI Solar: Early-stage company focused on high-purity material recovery from end-of-life PV modules. Comparable as a direct emerging competitor in PV recycling technology, though smaller and earlier-stage than Zilio's recycling plant footprint.

Direct peers

• Renergetica: Italy-based renewable energy developer and engineering firm focused on PV, wind, and hydroelectric project development and EPC. Comparable in scale and geographic focus as a mid-sized Italian renewable EPC operating across multiple renewables verticals.
• TerniEnergia: Italian renewable energy and environmental services group active in photovoltaic EPC, energy efficiency, and waste-to-energy projects. Highly comparable as a mid-market Italian multi-vertical renewable platform with similar EPC contracting model.
