Large penstock for Baltic power plant

Bilfinger, the industrial services provider, is assisting the energy company Ignitis Gamyba as it expands Lithuania’s Kruonis pumped storage power plant. The contract is being implemented in cooperation with the Voith technology group, and the aim is to enhance Lithuania’s green power capacity and its energy independence. Although originally planned as an eight-pump-turbine plant, only four 225-MW-capacity turbines actually went into operation upon completion in 1992. Voith Hydro­ is to supply a new fifth pump turbine, while Bilfinger will be bearing responsibility for the construction of a new exposed penstock to connect the power plant’s upper basin with its lower basin and the pump turbine. A team from Bilfinger Industrial Services Austria will be responsible for implementing the approximately 900-metre, 5,285-mm diameter exposed penstock along the entire value chain – including engineering, manufacturing, transport, installation, corrosion protection and commissioning.
