Limitations of the data

This dataset provides a handy indicator of how recent price increases are likely to impact on consumers. However, it does not reflect what customers have actually paid for electricity in any particular period, as the QSDEP only models one type of customer in each city or town, when in reality, Consumption and pricing plans vary significantly across households.

Inclusions

Lines prices cover both distribution and transmission services combined.

Exclusions

Prices assume that prompt payment discounts are claimed. They do not include multi-fuel and online discounts, incentive or retention payments, or rates paid by customers on fixed-term plans.

Prices do not include any ownership-based discounts and distributions from consumer trusts. If these discounts and distributions were included, the prices would be lower.
