Industrial Generator SIGENTICS Series Small Hydro

Long product lifespan and low lifecycle costs – the result of the highest quality standards

Hydropower is a particularly flexible energy source, and there is a large need for different hydro turbines. The Siemens answer is the Small Hydro generator series with its optimized hydropower specific profile, comprising flexible modular design, diverse cooling types, and the ability to respond to load changes within seconds. Synchronous generators of the Siemens Small Hydro series reach unparalleled efficiency up to 98% in the output range of 0.5-25 MVA. Being compact and insensitive to permanent humidity, even salt water, these generators are ideal for installations in weirs and dams.
