Time of Use Tariffs and Efficiency Incentives
energymadebetter
Customer response to more sophisticated price messages are a key economic benefit.
International experience in customer trials is encouraging.
Technology allows very complex tariff structures but customers require simplicity.
Time of use tariffs should shift demand patterns reducing costs (particularly network costs).
Time of use tariffs may also help reduce the overall level of demand.
A separate efficiency incentive to reduce overall demand will also be tested.
Tariff Incentives in General
Alternative tariff is designed to be revenue neutral for typical usage pattern.
Customer will get benefit of savings but will not be required to pay more on alternative bill.
Weekday and Weekend rates will vary.
Charges will be set at a higher rate in “Winter” (Nov, Dec, Jan & Feb).
Charges will be highest in the hours around tea time and lowest at night
A sample of customers will be able to claim a refund for a reduction in consumption.
The impact of the different types of tariff intervention will be decomposed.
