Canstar Blue
Outstanding Value Award Methodology –
Electricity & Solar Electricity Plans

Last updated: September 2023

What is the Canstar Blue Electricity and Solar Electricity Plans Outstanding Value Award?

Canstar Blue’s Outstanding Value Award for Electricity and Solar Electricity Plans uses a sophisticated ratings methodology, unique to Canstar Blue, which compares providers’ suite of Electricity products offered to consumers.

The Canstar Blue Outstanding Value Award is awarded to providers in each state/territory that provide the strongest Electricity or Solar offering across consumer profiles from Canstar Blue’s Electricity Value Rank.

What are the types of plans considered in the Outstanding Value Award?

Canstar Blue’s Electricity and Solar Electricity Outstanding Value Award consider Electricity plans that are either single rate, or controlled load. For the Solar Electricity Plans Outstanding Value Award, only plans with a solar feed-in tariff are considered.

Plans that do not have actual pricing available are not considered (e.g. plans that provide access to wholesale electricity spot pricing and are only able to provide an estimated usage rate are excluded from consideration in the Award).

How are electricity usage estimates determined?

For each tariff type, household size, and distribution network, Canstar Blue uses an estimated annual electricity usage.

For Controlled Load profiles, controlled load usage is assumed to be 30% of total usage.

How is the Outstanding Value Award determined?

Canstar Blue’s Outstanding Value Award for Electricity Plans (State/Territory) and Solar Electricity Plans (State/Territory) considers a retailer’s cumulative performance across single rate and controlled load plans over a three-month historical consideration, for each distribution network within the state/territory. The weights below represent the weighted distribution of each plan type considered in the award. To be considered for a State/Territory award, a retailer must be available in all considered distributors for that State/Territory.

Does Canstar Blue rate all products in the market?

Canstar Blue endeavours to include the majority of providers and products in the market and to compare product features relevant to most consumers in our ratings. However, this process is not always possible, and it may be that not every provider and/or product in the market is included in the rating, nor every feature compared that is relevant to you.

How often are plans reviewed for the Electricity Value Rank?

Canstar Blue monitors changes on an ongoing basis, and the Value Rank, Pricing Score and Feature Scores of each plan are fully re-calculated every day.

How are the plans ordered?

Canstar Blue ranks Electricity plans based on value-for-money. Whereby, the Value Rank takes into account a plans’ estimated annual cost and features offered as compared to the market. The plans that are lower in cost and have more features will be ranked higher than plans which have higher cost and fewer features.
