has run its own hydropower plants in
Opponitz, Gaming and Trumau, plus the
Nußdorf small hydropower plant since
autumn 2005. It has an annual capacity
of 28,100 megawatt-hours, which means
that over 10,000 households can be
supplied with green electricity. So-called
“matrix turbines” were installed under
the Schemerlbrücke truss bridge
designed by Otto Wagner. This is an all-
new concept of electricity generation in
