Why are there peak times for tariffs?
- Wholesale electricity is charged to us at 'off peak', 'peak' and 'super peak' so we pay more for our imports at different times of day
- Peak times put greatest demand on our network system
- We have to manage this demand/load to protect the network infrastructure
- If demand exceeds our supply contract we pay penalties
- We want to encourage customers to use electricity during off-peak times for heating and water heating by offering discounted rates
