Security of Supply

 

National hydro storage decreased 2 percentage points from 114% to 112% of average reflecting South Island hydro storage falling from 113% to 110% on the back of lower South Island inflows over the last week.

North Island storage has continued to rise to 121% of average. Inflows have returned to below average levels following last week’s significant inflow event.

A series of outages are planned at Pohukura, New Zealand’s largest gas field to early December. These come off the back of a medium term trend of production declines at the field. GIC estimates that production will be curtailed by between 20 and 50TJ for the duration of the outages.

National demand decreased to 726 GWh this week.

Renewable generation made up 87% of the mix.
