CER SRES STC Clearing House and REC Registry Trading Guide: Australia's Renewable Energy Market

Key Takeaways

• Australia's Clean Energy Regulator (CER) governs the trading of Small-scale Technology Certificates (STCs).
• STCs can be sold through the STC Clearing House or the open market.
• The REC Registry is the platform for managing STCs.
• Liable entities must surrender STCs annually based on the Small-scale Technology Percentage (STP).

What are Australia's STC Trading Venues and Mechanisms?

The Clean Energy Regulator (CER) in Australia oversees the trading of Small-scale Technology Certificates (STCs). These certificates are a key component of Australia's Small-scale Renewable Energy Scheme (SRES). You can sell STCs through two primary venues: the STC Clearing House or the open market (August 2026). The REC Registry platform is central to managing these certificates.

How We Verified Australia's STC Trading Information

We verified the information presented here by directly consulting the Clean Energy Regulator's official website on August 23, 2026. Our data is sourced from the CER's dedicated page for Small-scale Technology Certificates, which details the operational aspects of the Small-scale Renewable Energy Scheme.

Understanding the REC Registry and STC Clearing House

The REC Registry is the online platform where STCs are created, registered, and managed. It serves as the central database for all certificates under Australia's Renewable Energy Target. The STC Clearing House provides a mechanism for trading STCs at a fixed price, offering a level of price stability for participants. Alternatively, you can trade STCs on the open market, where prices fluctuate based on supply and demand.

Who is the Clean Energy Regulator?

The Clean Energy Regulator (CER) is the Australian government body responsible for accelerating carbon abatement for Australia. It administers schemes that incentivize renewable energy generation and emissions reduction, including the Small-scale Renewable Energy Scheme (SRES) and the Large-scale Renewable Energy Target. The CER has the authority to set the Small-scale Technology Percentage (STP) and manage the overall framework for renewable energy certificates.

What is the Small-scale Technology Percentage (STP)?

The Small-scale Technology Percentage (STP) is a crucial element of Australia's SRES. It dictates the number of STCs that liable entities must surrender each year to meet their renewable energy obligations. The CER sets this percentage annually, ensuring a market for STCs and supporting the generation of renewable energy. This mechanism creates a market for STCs, allowing those who generate renewable energy to sell their certificates.

Navigating Australia's STC Market for System Owners

If you are a system owner in Australia, understanding the STC market is essential for maximizing the value of your renewable energy installation. The process involves creating STCs based on eligible installations, such as rooftop solar PV systems or solar water heaters. For detailed eligibility requirements, you can consult our guides on solar water heater and heat pump eligibility and rooftop solar PV system eligibility. The calculation and assignment of STCs typically involve a registered agent, as explained in our guide on STC calculation and registered agent assignment.

Reader Protection: Market Realities

While the STC Clearing House offers a fixed price, the open market for STCs can be subject to price fluctuations. When trading STCs, ensure you are dealing with reputable agents or platforms. The Clean Energy Regulator provides the framework, but market dynamics can influence the final value you receive for your certificates. We do not publish specific open market prices as they are dynamic and not fixed by the regulator.
