Notes explaining the methodology used in the Quarterly Survey of Domestic Electricity Prices.
The Quarterly Survey of Domestic Electricity Prices monitors changes in line charges and retail charges for a domestic consumer using 8,000 kWh a year.
Data for the quarterly survey
Electricity tariff data for this survey are collected from Consumer New Zealand, and are the same data that are behind the Powerswitch website. Lines charges (transmission and distribution charges) are collected from the lines companies’ websites directly. Customer numbers for calculating weighted average prices are collected from the Electricity Authority.
Line charges and retail charges
The line charge figures represent the total (fixed and variable) cost of electricity transmission and distribution.
The retail figures show the total cost of electricity to a residential consumer and include the line charge component.
GST and discounts
GST and prompt payment discounts are included in the prices. Electronic payment, direct debit, or fixed term contract discounts are not included.For example, a retailer may charge a consumer 100 cents/day and 22c/kWh of electricity used. This would cost an 8,000 kWh a year customer $2,125 for the year.
