Hydro-electric technology
Controlling parallel
grid operations
We supply complete substations or individual components for your power station’s operation.
Our substations and controlling equipment can be used with every kind of turbine and will be customised to your needs.
We can supply, among other things:
- Transformers
- Medium voltage substations
- Generators
- Transformer substations
- Tranducers and meter cabinets
- Water intake control technology
- Power plant control systems
Controlling isolated operations
Generating energy from stand-alone solutions poses particular challenges for the control technology. Singly-operated power stations or combined operations from several generators. Consumption control and peak load management. Get the benefits of our experience!
For stand-alone hydro-electric power plants, we implement multi-faceted control and regulation technology.
To control the turbines, we provide:
- Nozzle regulators, flaps and flow diverter regulators
- Electrical loat regulators
- Eddy current brakes
- Water-saving controls
- Load regulators for mini power plants
- Power inverters with rechargeable batteries to increase the peak performance
Project planning
Making the right decisions in the project planning phase ist particularly important to ensure that the hydro-electric power plant meets your expectations and requirements. Take advantage of our extensive experience to make your power plant project a success.
We can advise you in...
- The construction of new plants
- Applying for new licenses
- Extensions
- Revitalising plants
- All manner of technical questions
Importance of hydro-electric
power plants
Since approximately 1900 small hydro-electric power plants are used for electricity generation in Tirol - a story of success. Today around 25% of the produced electricity come from small
hydro-electric power plants with less than 10 megawatt. Customer generation through hydro-electric power, photovoltaic, etc. is the easiest and economically best way to obtain electricity. Hydro-electric power is becoming more and more important due to the increasing awareness of substainability. The demand is expected to keep growing in the upcoming years.

Pelton turbines
Pelton or impulse turbines are usually used for middle-sized or large drops. They require hardly any maintenance and are also used in micro- and small applications, thanks to their low production costs. The turbine is well-suited to strongly fluctuating water volumes. The efficiency curve is flat, which ensures a high degree of efficiency in the partial load range.
We provide a range of Pelton turbines for different applications.
- Pelton turbines suitable for drinking water supplies
- Power stations designed with 2 or 4 bearings
- Horizontal or vertical shafts
- One to six nozzles
- Micro-plants
Revitalising plants
We offer a comprehensive range
of services for existing hydro-electric
power plants.
Our services include:
- Restoring or repairing Pelton turbines
- Maintenance work on couplings, gears and bearings
- Maintenance work on generators
- Restoring auxiliary drives
- Replacing faulty controlling devices
- Preparing measuring and test reports
- Efficiency measurements
