Tailrace Watered Up

Thanks to the hard work of our project team and contractor Barnard Pennecon, the tailrace channel is now full of water. The process of filling the tailrace channel with water started in November.

Excavation work to create the channel started in 2013. The channel is the area between the downstream side of the powerhouse and the river. It is 400 metres long and the width varies – it is 140 metres near the powerhouse and 100 metres at the rockplug. The rock located at the end of the channel (rockplug) was used to keep the powerhouse and tailrace channel dry during construction. 

This summer, the team started excavation activities to remove the remaining rock from the tailrace channel. Once the powerhouse is in operation, water will exit it through the tailrace channel and then re-enter the river downstream of the facility.
