On the road to a sustainable future

From the heart of the Dolomites to the whole world.
Besides the European countries in the Alps, the installations “Made by Troyer” can be found in different parts of the world, from South America to Northern Europe to Asia.

Since 1934 we have carried out more than 550 projects: here is a brief overview of the projects realized.


Products and Services

Reliability beyond tomorrow.

We supply complete electromechanical equipment for hydroelectric power plants: the construction of Pelton, Kaplan and Francis turbines as well as electrical engineering, control and automation systems, plus revitalization and service.


Always at your side

In addition to our two subsidiaries in Switzerland and India, we have established a network of partners and representatives in several countries around the world to provide direct support.



Corporate Social

Hydroelectric power is economical and environmentally friendly and,
in contrast to other energy sources, it has an excellent environmental record.
The high degree of predictability of the energy produced and the long lifetime of the waste and carbon dioxide-free production plants minimize the environmental footprint.

Work at Troyer


Ing. Sarah Usel Project manager ÖBB Infrastruktur AG Bahnsysteme, Vienna, Austria | Work realized: Spullersee power plant

We got to know Troyer AG as a competent and reliable partner. The company offers all-round expertise in the building, restructuring, restoration and revitalization of hydroelectric power equipment, while the staff have outstanding technical experience. Troyer AG reacts promptly and competently to specific client requirements.

Rudolf W. Jacobs CEO Secacao Group (GT) | Realized project: HPP Guayacán

Staff and engineers at Troyer are highly qualified and experienced; naming a project manager in Troyer assures a centralised and orderly process. A sense of pride is present in the highly committed Troyer team. Integration of the control equipment in-house led to a surprisingly fast commissioning. Troyer equipment has fulfilled and exceeded technical requirements.

Hubert Brunner Managing director, EUM co-operative, Passeier (BZ) | Work realized: Bergkristall-Stieber power plant

We have from the beginning worked with the long-established Troyer company, which can in particular offer skilled consultation. The fact that Troyer can do everything, from the turbine and the equipping of the distribution cabins right through to the network control system, is a sound basis for the smooth running of the network.

Daniel Kressig Overall project manager, Axpo Power AG / Hydroenergie, Baden (CH) Work realized: Tasnan power plant

Troyer keeps its word: a family business that offers outstanding quality while still remaining cost-conscious. Spontaneous, honest and very friendly staff make dealing with the project a pleasure, while their consideration and assistance ensure solution-oriented planning and execution – we highly appreciate the work of this dedicated power plant supplier.

Christopher Morgan Consigliere Delegato Eusebio Energia, Gallarate (I) | Centrali realizzate: Bessè, Bruni, Frizzi, Gazza, Facchini, Marchesini, Margherita, Selladi

Troyer è il nostro principale fornitore di turbine da oltre 10 anni. La società è sempre attenta a utilizzare nuove tecnologie nella produzione dei macchinari. Ottima preparazione dei tecnici installatori anche aiutati dal premontaggio in officina che permette tempi di installazione in cantiere minimi e senza bisogno di modificare quanto preparato.

Rolf Stalder Engineering and project management, ewl energie wasser luzern, Lucerne (CH) | Work realized: Obermatt power plant

Troyer offers sound, motivated and competent staff! Co-operation with the customer is based on mutual trust and appreciation. This excellent, family-run company is lean, fast and innovative in its actions. Working with Troyer was an enjoyable and exciting experience where personal commitment really paid off.

Jonas Kalbermatten Head of power plants / senior management, Enbag AG | Work realized: Mund power plant

Solution-oriented working is always a priority from the bid phase right through to the commissioning of a hydroelectric power plant. Troyer demonstrated that, in addition to “classic turbining”, it is capable of satisfying even the most complex customer requirements for a holistic water management system with various feeders, consumers and machine units.
