Hydro Generation

The main (Chinese) hydro generator is performing well following significant expenditure over the past two years repairing the penstock leaks between the intake and the stilling tank and replacing the main actuator shaft. We have also completed refurbishment of some parts of the Gilks hydro (the original Hotel unit) as this is still a good reliable backup for the main unit.

During August we experienced a period of very low flows in the Bowen River, where the hydro intake is situated. The low flows had the effect of restricting peak generation and we had to implement load shedding in order to prevent disruption to supply. In the past we have experienced similar low flows but normally around March – April.
