StreamDiver powers Swedish hydro plant: technology reducing civil construction investment, maintenance cost and environmental impact
StreamDiver – harnessing low head potential
Core of the StreamDiver technology is the power unit consisting of a permanent-magnet generator embedded in an oil free bulb unit, available in the sizes from 50 kW up to 800 kW. The strength of this technology is the flexible use: the power unit can either be completely submerged: thus it allows for standalone operation independently of civil structures. Also it can be integrated into existing power plants allowing for economic rehabilitation, reducing investment to a minimum. For example, existing weirs and dams can be used to generate electricity. The StreamDiver technology can thus make a sustainable contribution to the continuing expansion of climate-friendly energy production.
With the StreamDiver, Voith developed a turbine generator unit in the field of small hydropower, constructed to be compact, simple and therefore lowmaintenance. In addition to the technical and ecological benefits, this innovative product provides the opportunity to develop new and previously unusable hydropower locations. The StreamDiver's construction means it can be used in sites where it has previously been impossible economically or for environmental reasons.
Voith estimates the StreamDiver technology for a potential of 5 GW worldwide. Regions holding the most potential are North America as well as Europe, especially its North and its East. For nearly three years now, a StreamDiver pilot project is successfully operating for Austria’s largest utility, Verbund, at its 5 MW Nussdorf plant located near Vienna on a side canal of the Danube River. Nussdorf project was initially slated to last two years, but its success has extended its life for a third. With a maximum output of 450 kW, the StreamDiver now has over 24,000 operating hours, and has exported more than 7 GWh of electricity.

The Importance of Hydropower
Hydropower is the largest, oldest and also most reliable form of renewable energy generation. Worldwide it makes an indispensable contribution to stable power supplies and hence to economic and social development – both in industrial countries and in emerging markets. At the same time, hydropower significantly contributes to climate-protecting energy generation. Voith has been a leading supplier of this technology since the early beginning, and continuously develops it further.
