This project is located near the town of Zeballos in British Columbia, Canada.  They are designed primarily for energy delivery directly into BC Hydro grid via. a new 18.6km long transmission line. 

Designed by DTL with computational fluid dynamics (CFD) software to increase the screen surface area to structure size and weight ratio as well as to keep the water approaching velocity through the screens below an allowable value, the 'gear-shaped' intake structure diverts water to the powerhouses via a 900m tunnel, low and high pressure penstocks, bifurcations, shut off valves.  This intake was also designed to eliminate sediment and debris from the diverted water. 

The main powerhouse operates on the level control of the lake, and the fish flow powerhouse was designed to operate all year round to maintain water flow in the creek.  The power plants are normally operated in automatic mode.
