Mavel installs first unit at Štvanice project, Prague

9 August 2018

Mavel has successfully installed, tested and commissioned the first of three generating units at the Štvanice hydroelectric plant on the Vltava River in central Prague, Czech Republic. 

The output of the new double regulated Kaplan "S" turbine Mavel Model KS3400K4 exceeded guaranteed values by more than 25%.

Czech water management authority Povodi Vltavy awarded the contract to Mavel in August 2017. The engineering, procurement and construction (EPC) contract was for the complete rehabilitation of the  power plant, including mechanical and hydraulic design, replacement of three horizontal turbines,  refurbishment of generators, supply of a control system and all related civil work.  

Installation of the first unit began in January 2018 with full commissioning in March 2018 and performance testing completed in July 2018.  Installation of the second unit is underway and expected to be completed next month with the third and final unit commissioned in May 2019.

Prior to refurbishment the maximum power per unit was 1.6 MW.  Mavel’s contract mandated a  guaranteed output of 1.75 MW.  The new Mavel turbine reached 2.1 MW before the output was limited  due to the capacity limitations of the existing generator.
