Waneta Expansion Project

Waneta Expansion Project

The Waneta Expansion Project will add 355 MW generating capacity to the existing Waneta Dam with the construction of two infeed tunnels and turbines in a new powerhouse and tailrace.

Nelson and Castlegar Ready Mix are proud to be supplying ready mix concrete for the construction of the new powerhouse from our portable concrete batch plant located a few kilometres from the job site. This job will require over 65,000 m3 of high specification concrete and aggregates delivered over three years.

This project is characterized by a continuous high resource demand—of crew, equipment and aggregate. To date, the project has required two continuous pours of 1000 m3 of concrete. A further challenge facing this year-round project is the need to maintain temperature control of the delivered concrete within a tight temperature range despite heat and low ambient temperatures in summer and winter.
