What Tozzi Sud S.p.A does
Tozzi Sud S.p.A. is an Italian Engineering, Procurement, and Construction (EPC) contractor headquartered in Ravenna, Emilia-Romagna, founded in the 1960s and operating today with approximately 29 employees. The company is organized into two business units: an Industrial BU providing electrical and instrumentation (E&I) erection, construction management, commissioning, and maintenance services for Oil & Gas, refinery, chemical, power, and industrial clients; and an Energy BU delivering turnkey EPC services for renewable energy plants (photovoltaic, BESS, onshore wind), high-voltage electrical substations compliant with Terna and Enel standards, and custom prefabricated metal cabin solutions (ISO Std. SHELTERs) including MV/LV transformation cabins, GIS distribution cabins, and SCADA/SAS automation/control cabins. Technical scope spans 15-20kV MV, 36kV HV, and 132/150kV HV network works, plus automation systems integration (DCS, PLC, SCADA), process instrumentation, fiber optic cabling, and F&G systems.
The company generates revenue through project-based EPC contracts awarded via competitive bidding and direct enterprise relationships with Italian utilities and international energy developers, with multi-year contract cadences. Customers are primarily enterprise B2B — including Terna (Italian grid operator), Enel, independent power producers, and renewable energy developers across Europe. Pricing is custom per project based on scope, voltage level, and complexity; no standard tiers are published. The company holds ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, SCC VCA** 2017/6.0, and SOA OG1 (valid through 2028) certifications, and has adopted a Gender Equality Policy under UNI/PDR 125:2022. In February 2025, Gruppo ISOLMEC acquired Tozzi Sud S.p.A. through an insolvency procedure, making it a subsidiary of Isolmec Holding S.r.l. (Milan); the company continues to operate under its own brand alongside ISOLMEC S.p.A. and COIMEC within the ISOLMEC Group.
