Bulb turbines for more power

Traunleiten, an existing hydropower station in Austria will be replaced by a complete new construction during the next two years. The owner, Wels Strom GmbH, is starting the largest project in its history with this project, located in a suburb of the city of Wels. The project is targeting an 80% increase in power output with a hydroelectric power production of 91 GWh annually.
