What TerniEnergia S.p.A. does

TerniEnergia Progetti S.r.l., the carve-out photovoltaic unit of the former TerniEnergia S.p.A. (subsequently AlgoWatt S.p.A.), is an Italy-headquartered engineering, procurement, and construction (EPC) contractor and operations and maintenance (O&M) provider focused exclusively on utility-scale photovoltaic plants. The company delivers full-scope EPC work — covering technical and permitting design, procurement and supply chain coordination, mechanical and electrical construction, Balance of Plant activity, and commissioning — alongside multi-year recurring O&M contracts, revamping and repowering modules, and asset management services. As of the most recent disclosures, the firm reports a cumulative track record of 614+ MWp installed across five countries (Italy, Greece, South Africa, Romania, and Tunisia) and more than 50 plants under O&M management in 2025-2026.

The underlying technology stack pairs a digital monitoring platform — integrating SCADA and inverter data, custom dashboards, automated alerts, and 24/7 ticket management — with drone-based aerial thermography using high-resolution thermal cameras and RGB image analysis for hot spot, damaged-cell, soiling, and visual-defect detection. Management reports a 99.5% average uptime across managed plants and claims a 25% reduction in downtime and 12% performance improvement as outcomes of the digital-monitoring stack. The company holds ISO 9001:2015 (quality) and ISO 45001:2018 (occupational health and safety) certifications. Customer relationships are enterprise-grade and span institutional investors, international developers, utilities, and corporate energy buyers, including Terna, Acea, ENI, EDF, Verbund, Ferrero, Aeroporti di Roma, Buzzi Unicem, X-Elio, Enfinity, and Circet.

Revenue is generated through project-based EPC contracts (one-time recognition) supplemented by recurring multi-year O&M and asset management fees, with all pricing negotiated on a per-project or per-contract basis and not publicly disclosed. Following AlgoWatt S.p.A.'s judicial liquidation in 2024, Terni Grandi Impianti S.r.l. acquired TerniEnergia Progetti in March 2025, simultaneously conferring the O&M business unit into the company, reconstituting share capital, and integrating EPC and O&M activities under one entity. TerniEnergia Progetti reported €5.4M in operating revenues for fiscal year 2025 (+20% YoY), EBITDA above €600K, and a positive net result, with an employee headcount in the 51-100 range.
