Detailed tests regarding conditions and operation were carried out in Voith Siemens’ corporate technology facilities. Representatives of the customer, Yellow River Upstream Hydropower Development Company, attended the tests for the turbine, which was designed and optimised specifically for the power station.

Voith Siemens Hydro Power Generation Shanghai was awarded the US$83M Laxiwa contract for five 711MW Francis turbines in August 2004.

The Laxiwa project is part of the Chinese National Hydro Power Development programme, and is the biggest project along the Yellow river. This successful test marks the final step of the hydraulic development phase for the project.
