Navigating through a Power Purchase Agreement (PPA) can be a daunting task, especially for those seeking clarity on renewable energy agreements in Australia. At Amazon Energy, we're here to guide you through the intricacies of this vital document, drawing on our expertise as Australia's premier solar panel providers and installers.

What is a PPA?

A PPA is a contractual arrangement between one or more parties for the procurement of energy. While it can encompass various forms of energy production and consumption, our focus here is on renewables.

A solar PPA, for instance, empowers renewable energy projects like wind and solar farms by ensuring a guaranteed customer base upon completion. Essentially, these agreements play a pivotal role in propelling the growth of solar energy facilities across Australia. Moreover, businesses can transition to solar energy without the financial burden of installing and maintaining their own solar panels.

Types of Power Purchase Agreements


In Australia, there are three primary types of PPAs tailored for different markets:

  • Retail-sleeved PPAs: Involving three parties—the solar farm, the electricity retailer, and the customer—these agreements typically span a contract period of seven years or more. They provide businesses with a fixed energy rate, shielding them from market price fluctuations.

  • Commercial/Front-of-meter PPAs: This simpler arrangement allows businesses to directly source energy from a solar farm, often referred to as a 'front of the meter PPA.' It is particularly well-suited for larger enterprises with substantial energy needs.

  • On-site PPAs: Also known as 'behind the meter' PPAs, this model involves a solar energy company installing and maintaining a solar system on your premises. You pay solely for the energy you produce and consume, making it an attractive option for businesses seeking to reduce energy costs.

Considerations for PPA Agreement Solar

Before entering into a PPA, it's crucial to keep a few key factors in mind:

  • Ownership of the solar system: Specifically relevant for on-site PPAs, consider what happens to the solar system once the contract concludes. Some agreements facilitate the transfer of ownership to the business or property owner.

  • Pricing structure: Understand the pricing model, whether it charges for all generated solar energy or only what you use. For retail-sleeved and commercial PPAs, clarity on fixed pricing or any tiered adjustments is essential.

  • Length of contract: Tailor the length of the PPA contract to your business's operational needs. Longer contracts offer stable pricing, while shorter ones provide flexibility.

  • System maintenance: For on-site PPAs, ascertain who is responsible for maintaining the solar system. Typically, this falls under the domain of the solar provider.

In summary, a PPA is a powerful tool for businesses looking to adopt solar energy solutions.
