Voith’s HyCon GoHybrid achieves successful first year of operation

7 June 2022

Voith Hydro’s HyCon GoHybrid hydraulic unit for turbine governors in hydropower has been successfully operating for just over a year at the site of SWU Energie GmbH in Wiblingen, Germany, with the product also successfully operating at Fortum’s Nain project near Hagfors in Sweden.

The HyCon GoHybrid was launched to the market by Voith Hydro in May 2021, with its first installation for SWU Energie GmbH (a subsidiary of Stadtwerke Ulm/Neu-Ulm GmbH) providing significant savings in energy.  The company said it was highly satisfied with the variable-speed pump drive’s consumption of only 100kWh since commissioning, requiring 92% less energy in operation compared to previous solutions.

Swedish energy company Fortum has also benefitted from the installation of HyCon GoHybrid at its Nain project on the Uvån River. Nain features Francis twin turbines with a capacity of 6.8MW commissioned in 1944, and these proved to be suitable for the GoHybrid’s smallest design size. 

The turbine governor for Nain was successfully tested at Voith Hydro’s headquarters in Germany in the summer of 2021 – shortly after its market launch – and was commissioned and handed over to the customer in November. 

"The HyCon GoHybrid is a compact unit that contains less oil, has low energy consumption and exact control. Since the GoHybrid makes no noise during regulation or pump operation and requires very little space, it has improved the working environment in the power station a lot," explained Fortum project manager Per Jansson. "Since commissioning in November 2021, we have had no problems and are very satisfied with both the turbine governor as well as with Voith's support."
