LITOSTROJ MANUFACTURES RUNNERS FOR AUSTRIAN ROSSHAG POWER PLANT
Litostroj Power of the ENERGO-PRO Group
will produce four runners for the Austrian Rosshag pumped-storage hydropower
plant. The contract also includes the development of the hydraulic design and
model tests in the hydraulic laboratory. Thanks to the contract, Litostroj
Power has won its eighth contract from the Austrian power company Verbund Hydro
Litostroj Power, which manufactures
turbines and other hydropower equipment in Ljubljana, Slovenia, together with
Litostroj Engineering in Blansko, Czech Republic, and other sister companies,
form the industrial pillar ENERGO-PRO, a multinational operator of
hydroelectric power plants. "We are further strengthening our industrial
pillar. We appreciate the fact that we are becoming a stable supplier of our
solutions for such an important client as Austrian Verbund. We see this further
contract as recognition of Litostroj's creative and reliable approach,"
said Pavel Váňa, CEO of the ENERGO-PRO Group.
Litostroj Engineering will be in charge of
the hydraulic design of the runners and of the tests in the hydraulic
laboratory in Blansko for the Rosshag power plant while Litostroj Power will be
in charge of the manufacture of the runners in Ljubljana and the final delivery
of the turbine.
The Rosshag pumped-storage power plant with
four 65-megawatt Francis turbines is located in Zillertal.
The water head from the Schlegeis accumulation reaches 640 metres, which is
equal to the height of ten Prague’s Petřín lookout towers or about two Eiffel
towers. Rosshag is thus approaching the parameters of the neighbouring Häusling
power plant, which boasts the world record of 728 metres – the highest water head in the world that uses a Francis
Litostroj Power had previously won a
contract at the Häusling power plant to modernize its two turbines. The
turbines then received new runners in 2019 and 2020 thanks to the cooperation
of engineers in Blansko and Ljubljana. The Rosshag and Häusling power plants
are located in the same valley, just a few kilometres apart.
Litostroj Power is currently also
implementing four other projects for Verbund – Malta Oberstufe, Limberg I,
Töging and Ottensheim—Wilhering.
