What are STCs and VEECs for water heaters?


STCs and VEECs represent a reduction of energy used to heat water when a high efficiency or solar water heater is installed.

By installing an eligible water heater and submitting a claim to Green Energy Trading you will be eligible to receive a certificate payment.


When can certificates be claimed and do they expire?


Certificates can be claimed from the date the system has been completely and correctly installed.

Green Energy Trading highly recommends claims are submitted ASAP following installation to ensure they don’t expire.

STCs: Certificates must be claimed within 12 months of the installation date.

VEECs: Certificates must be claimed by June 30 of the year following the year of installation. For instance:

If the installation takes place on December 30, 2018, certificates need to be claimed by June 30, 2019 (6 months in total). If the installation takes place on January 1, 2019, certificates need to be claimed by June 30, 2020 (18 months in total).


Can STCs and VEECs be claimed for multiple water heaters at the same address?


Yes. However, we need some additional information to make processing the claim straightforward.

The assignment form need to describe where each solar water heater (and the tank serial numbers) is located on the property. For instance:

A system with serial number X is installed at the rear of the house and the system with serial number Y is installed on level 1 of the main building.

A diagram of the property and photos of the installation, showing the location of the existing and new systems, is also very useful for processing your form.

In Victoria, up to two water heater replacements at a residential premise can claim VEECs. There is no such limit for water heater replacements at a business premises.
