Solar Power Purchase Agreements (PPAs) have become increasingly popular in Western Australia (WA) as a means of accessing solar power. These agreements involve a supplier installing and maintaining a solar power system at a customer’s premises at no up-front cost to the customer. In exchange, the customer agrees to purchase the energy generated by the system from the supplier over an agreed period at an agreed rate.

The unique nature of these agreements, however, calls for a distinct regulatory framework. This article delves into the specifics of PPAs in WA, focusing on the available retail licence exemptions, the conditions tied to these exemptions, and the obligations for reporting and disclosure.

Retail Licence Exemptions for Solar PPAs

In August 2016, the Minister for Energy approved a licence exemption framework for suppliers of solar PPAs. These licence exemptions enable suppliers to apply for individual retail licence exemptions, subject to consumer protection and compliance reporting conditions. The exemptions are granted under section 8 of the Electricity Industry Act 2004 and are provided if the applicant meets the exemption requirements.

Conditions of the Licence Exemptions

The consumer protection and compliance reporting conditions associated with the licence exemption framework are crucial for ensuring that customers are adequately informed and protected.

One of the conditions stipulates that solar PPA suppliers must provide prospective customers with a Disclosure Statement before they sign a contract. This statement should contain important information such as the length of the contract, associated fees and charges, termination rights and obligations of both parties, customer options at the end of the contractual period, and details about the maintenance and repair of the solar power system.

Additionally, the exemption conditions mandate that the suppliers must comply with Australian Consumer Law (ACL) protections, especially when it comes to the quality of services and goods provided.

Reporting Obligations

Solar PPA suppliers operating under a licence exemption are required to report annually to the Public Utilities Office. This reporting is intended to provide an understanding of the development and uptake of solar PPAs, as well as any consumer complaints.

The information to be reported includes the number of solar PPAs agreed and active during the reporting year, the number of solar power systems installed under solar PPAs, the amount of solar power system capacity installed, and the number and type of customer complaints received. This data needs to be broken down by residential and commercial customers, providing two distinct sets of information.

Disclosure Obligations

As mentioned earlier, a crucial part of the exemption conditions is the requirement for solar PPA suppliers to provide a Disclosure Statement to prospective customers. This statement should provide a comprehensive overview of the agreement, outlining all the applicable fees and charges, the termination rights and obligations of both parties, the customer’s options at the end of the contractual period, and details on the maintenance and repair of the solar power system.

The statement should also specify the per-unit rate the customer will pay for the generated electricity and how the rate can change over the life of the solar PPA. It’s essential that customers are aware of any potential changes to costs before entering into an agreement.


The advent of Solar Power Purchase Agreements in Western Australia has necessitated a distinct regulatory framework to ensure that both suppliers and customers are on the same page. The retail licence exemptions, conditional on compliance with consumer protection and reporting obligations, offer an avenue for these agreements to take place under a controlled environment.

By committing to transparency through the fulfilment of disclosure obligations, solar PPA suppliers can ensure that customers make informed decisions, fostering a sustainable and consumer-friendly solar power market in Western Australia.
