Hydraulic turbine / Pelton
max. 350 MW Alstom Power Generation


  • Power source:


  • Technology:



They can operate under a wide range of heads, from 200 to 1800 meters.

Based on our experience in the field, we offer vertical shaft machines that are equipped with multi-jet collectors up to an output of about 350 MW, and with runner diameters up to 4 m.

For smaller units, we provide horizontal shaft single or double runner Pelton turbines with one or two jets. These turbines operate economically with the lowest discharges.

Alstom patented Hooped Pelton runners design, whose buckets are supported by 2 separate hoops, minimises the fatigue stress at bucket fixation, reducing the inspection and maintenance costs and maximising the plant availability. Capable of providing the same hydraulic efficiency levels as a standard Pelton, but better resisting to mechanical stress, the need for repeated quality inspections and associated labour costs and plant outages. As it is possible to replace individual buckets instead of the complete runner, replacement costs of ageing runners are reduced.
