Figure 7-3 Typical CBD demand profile
The Auckland CBD load is characterised by the summer profile where load rises quickly in the morning and drops off equally as rapidly in the evening. The winter load profile demonstrates a similar characteristic to the summer although less aggressive uptake after 7:00am and a slower ramp-down in the evenings. The peak load in summer is driven mainly by air-conditioning, adding an extra 10% load above the winter demand profile.
