The Slovenian manufacturer of water turbines Litostroj
Power from the Energo-Pro Group signed a contract with its client HESS (Hydroelectric
power stations on the lower Sava River) and will participate in the development
of a new hydropower station Mokrice. The delivery includes three horizontal
Bulb units with a runner of 4.8 m in diameter as well as all the auxiliary
systems. The value of the contract is less than EUR 19 million.
Mokrice is the fifth and the last hydropower
station in the cascade on the lower Sava just before the border with Croatia.
The installed capacity of the entire cascade will be 187 MW, while the capacity
of Mokrice itself will be 28 MW. “Litostroj Power supplied equipment for all
the other projects in this cascade – for the hydropower stations Boštanj, Arto-Blanca,
Krško, and Brežice – therefore the current project is developed in continuation
of our previous collaboration with this leading client in Slovenia,” adds Pavel
Váňa, the Executive Director of Energo-Pro. The project of the new hydropower
station Mokrice was adjusted several times to perfectly meet all the demanding
conditions for a fully ecological operation without any adverse impact on the
ecosystems of the Sava and Krka rivers.
In these days, the works on the project have
started at the hydraulic laboratory of Litostroj Engineering in Blansko, Czech
Republic, as the guaranteed performance of the turbines needs to be confirmed
by a model test before the works can continue. To do so, the engineers in
Blansko first had to design an accurate model of the new turbine.
Works started also on the design and technical
documentation for the prototype units. After the collaboration with the
Slovenian client is approved, Litostroj shall commence its production
activities in order to guarantee a top final quality and timely delivery.
Litostroj Power has 50 months to deliver the full contract including the
installation and testing.
