Small-scale Technology Certificates (STCs)

As of 1 January 2011, the enhanced Renewable Energy Target (RET) was split into two parts, the large-scale renewable energy target (LRET) and the small-scale renewable energy scheme (SRES). Under the SRES, new solar and heat pump hot water heaters may be eligible to create small-scale technology certificates (STCs), formerly known as renewable energy certificates (RECs). Householders can create and trade these certificates on their own, but it is more common for Registered Agents to create and trade STCs on behalf of householders. The STCs benefit for consumers usually comes as a point of sale discount. Most retailers will advise potential buyers how many STCs are provided by each solar or heat pump hot water system model and how much each of those STCs are worth. The retailers then provide a discount to the buyer, meaning the cost of the hot water system to the householder is reduced.

The Renewable Energy Bonus Scheme—Solar Hot Water Rebate may apply to systems that earn 20 STCs or more at the time of purchase at the installation address. Hot water system retailers can also advise on the number of STCs assigned to a system.
