Hydro Lake Storage Continues to Decline

Tuesday, September 5th, 2006

National hydro lake storage continued its decline during August, reaching its lowest level for the year at the end of the month.

Careful management of electricity generating resources during the winter of 2006 maintained the hydro storage at levels well above the 1992 crisis year, managing to meet demand caused by 40-year record snows in the South Island and very wet conditions in parts of the North Island.

However, hydro reserves at the end of August dropped below the storage levels at the same time at end of the 1992 crisis period, highlighting a continued need for more generating capacity.
