Hydro Exploitations

What Hydro Exploitations does

HYDRO Exploitation SA is a Swiss industrial services company headquartered in Sion, Valais, that operates and maintains hydroelectric power generation infrastructure on behalf of its utility shareholders. Founded in June 2002 as a consortium vehicle by Grande Dixence SA, EOS Holding SA, and FMV SA — later joined by Romande Energie Holding SA and Les Forces Motrices de la Gougra SA — the company employs approximately 480 staff distributed from Haut-Valais to the Vaud Jura region and operates 46 hydroelectric facilities producing more than 16% of Switzerland's hydroelectric energy.

The company's offering is structured around six service pillars: Operation and Maintenance (including 360° preventive maintenance), Mechanical Rehabilitation (anchored at the central Martigny workshops handling turbine wheel restoration, component revision, and precision machining), Measurements and Expertise (electrical, mechanical, civil engineering, geodetic surveys, structural inspection, and laboratory analysis), Engineering (with approximately 100 multidisciplinary engineers covering feasibility through commissioning), Control-Command (automation and information management from water intake through turbine, including large- and small-hydraulic schemes, water management, protection, telecommunications, and medium/low voltage electrical), and Specialized Maintenance Services (subaquatic inspection, single- and multi-beam bathymetry, cryogenic cleaning, QES/Quality-Environment-Safety services, and training). Underlying technology is classical industrial automation and control engineering integrated across water, mechanical, and electrical subsystems, supplemented by in-house diagnostic capabilities such as rapid non-destructive metal and alloy analysis.

The business model is B2B, sales-led, with managed services and project-based professional services delivered directly by company personnel. Revenue streams comprise recurring hydroelectric facility operation and maintenance contracts, multidisciplinary engineering and consulting fees, project-based mechanical rehabilitation and machining work billed from the Martigny workshops, and specialized measurement and diagnostic services. Pricing is quote-based and not publicly disclosed; the customer base is concentrated among the consortium shareholders and other Swiss hydroelectric plant owners and operators, with operations confined to Switzerland and no disclosed international expansion, venture or private equity investment, or public listing.
