Certificate surrender

Written and checked by the Energy Merchants desk · Reviewed 3 October 2026

Certificate surrender is how the certificate markets close the loop. A liable entity, usually an electricity retailer, holds certificates in the registry and surrenders them to the regulator to show it has met its legal obligation. Once surrendered, a certificate is retired. It cannot be transferred or sold again.

It is the demand side of the story. Installers and generators create certificates, traders move them, and surrender is the end of the line. See liable entity.

How it works across schemes

• Renewable Energy Target. Retailers surrender STCs on a regular schedule, quarterly at the time of writing, and LGCs annually, with a shortfall charge if they fall short. The Clean Energy Regulator (CER) administers the process in the REC Registry. Confirm the dates on the CER’s site.
• Victorian Energy Upgrades. Retailers surrender VEECs against their annual targets, with penalties for a shortfall.
• NSW schemes. Retailers and other scheme participants surrender ESCs and PRCs to meet their obligations under the ESS and PDRS.

In practice

Surrender matters to installers because it drives demand and therefore price. The STC clearing house, which lets certificates be sold at $40, sits behind the market because retailers must have certificates to surrender. See STC clearing house. Spot prices have been roughly $38 to $40 at the time of writing.

For a trader, deadlines create rhythm: demand is strongest as quarter-end approaches, and settlement desks plan for it. It rarely changes anything for an installer except the timing of when buyers are most active.

Common confusion

Surrender is not the same as transfer. A transfer moves a certificate from one account to another, and the certificate stays alive. Surrender ends its life. See the STC transfer list.

It is also not the same as invalidation. A certificate found to be invalid is removed because the claim was wrong, which can lead to a clawback. See STC clawback.
