GRUPO EMENASA

What GRUPO EMENASA does

Grupo Emenasa is a privately held Spanish industrial conglomerate founded in 1959 and headquartered at Avda. Beiramar 75 in Vigo, Pontevedra. The legal parent is Electromecánica Naval e Industrial, S.A. (EMENASA), a Spanish public limited company (S.A.) registered in Pontevedra. The group is structured as a collection of 14 wholly-owned operating subsidiaries that collectively serve the naval, industrial, and hydroelectric-energy sectors, with claimed commercial presence in more than 30 countries. Headcount is disclosed at 600+ professionals, including 150+ engineers, supported by 20,000+ m² of production capacity and 300,000+ machining hours per year.

The group's core technical capabilities span four engineering disciplines — electricity, mechanics, hydraulics, and electronics — applied principally to ship maintenance, repair, and transformation, alongside industrial automation/robotics and hydroelectric equipment manufacturing. Each subsidiary operates a specialised domain: Baliño (propulsion systems, shafting, stern-tube seals), Emenasa (electrical installations, motors, generators), Emenasa EIA (industrial installations, robotics, automation), Mecanasa (mechanical repairs, diesel engines), Fundivisa (propeller casting), Progener (propulsion engines, generators, ballast water treatment), Nuñez Vigo (hydraulic systems, steering gear, deck machinery), Enaradio (naval electronics, bridge equipment), Vicus (propulsion engineering, rudder/shafting design), HGA (shipyard management software), García Costas (electric machinery, processing equipment), Main Solutions (vessel electrical engineering and automation), and Emenasa Lusitania (regional entity serving Portugal).

The business model is sales-led and direct, with no public pricing, no subscription or SaaS disclosure, and no app or API surface. Revenue is generated through professional services (vessel repairs, engineering, technical after-sales) and hardware sales (propulsion components, generators, electric motors, hydraulic turbines, propellers). Annual billing exceeds €150 million. Customers are enterprise B2B — primarily shipyards, vessel operators, and naval fleet owners — with secondary segments in industrial manufacturing and hydroelectric utilities. The group operates with no identified external institutional investors, private-equity backing, or public listing.
