Due to low reservoir levels at the Sloy scheme, current forecasts indicate that, if conditions continue, remaining available water may be fully utilised pending further inflow. This is expected to result in an aggregate unavailability of 152.5 MW across BMUs M_SLOY 1, T_SLOY 2, T_SLOY 3 and M_SLOY 4, which will be confirmed by MEL submissions.

Due to low reservoir levels at the Sloy scheme, current forecasts indicate that, if conditions continue, remaining available water may be fully utilised pending further inflow. This is expected to result in an aggregate unavailability of 152.5 MW across BMUs M_SLOY 1, T_SLOY 2, T_SLOY 3 and M_SLOY 4, which will be confirmed by MEL submissions.
