NUSSDORF<br />
HYDROMATRIX ® as best solution<br />
With the planned realization of a<br />
small-scale <strong>hydro</strong>power plant near<br />
the Schemerl Weir at the <strong>in</strong>take of<br />
the Vienna Danube Canal, Verbund-<br />
Austria Hydro Power and its project<br />
partners EVN and Wienstrom,<br />
have sent an important signal concern<strong>in</strong>g<br />
the best possible use of<br />
<strong>hydro</strong>power.<br />
Location of plant<br />
The idea of us<strong>in</strong>g the Danube Canal for<br />
the generation of power is closely<br />
related to the construction of Freudenau<br />
power station on the Danube.<br />
Concepts for the use of the banked-up<br />
waters of the new power station by<br />
means of a small-scale <strong>hydro</strong>power<br />
plant near the exist<strong>in</strong>g weirs at the <strong>in</strong>take<br />
of the Danube Canal (Schemerl<br />
Weir) were considered already at the<br />
end of the 1990s. However, at that<br />
time this project was not pursued<br />
for economic reasons.<br />
The realization of the “Nussdorf<br />
small-scale <strong>hydro</strong>power plant” project<br />
first became economically viable<br />
follow<strong>in</strong>g the pass<strong>in</strong>g of new “green<br />
power” legislation and the a<strong>va</strong>ilability<br />
of the new HYDROMATRIX ® <strong>tech</strong>nology.<br />
A major feature of the project is its<br />
careful <strong>in</strong>tegration <strong>in</strong>to the exist<strong>in</strong>g<br />
Nussdorf Weir build<strong>in</strong>g complex designed<br />
by the famous Jugendstil<br />
architect Otto Wagner.<br />
The contract will be executed by<br />
VA TECH HYDRO together with Porr<br />
Technobau and Verbundplan as<br />
consortium leader.<br />
The small-scale <strong>hydro</strong>power plant<br />
consists of a 30 m long, approx. 12 m<br />
wide and 7 m high over-flow hollow<br />
body weir with attached pneumatically<br />
operated spillway gates, twelve<br />
HYDROMATRIX ® turb<strong>in</strong>e generator<br />
units and an operation build<strong>in</strong>g.<br />
With the HYDROMATRIX ® concept it is<br />
now possible to comply with the exist<strong>in</strong>g<br />
weir operat<strong>in</strong>g procedure and<br />
secure the required flow for navigation<br />
at all times of the year.<br />
KEY PROJECTS<br />
The HYDROMATRIX ® plant is scheduled<br />
to commence supply of electricity already<br />
<strong>in</strong> summer 2005. From today’s perspective,<br />
the electricity produced will meet<br />
the needs of about 7,500 households.<br />
