STCs, VEECs, and LGCs explained. Calculate what your commercial solar system is worth in rebates and ongoing revenue.
Australian businesses can access federal and state incentives that significantly reduce the cost of going solar. Here is how each one works.
Federal rebate for systems up to 100 kW. Available nationwide as a one-time upfront discount worth up to ~$22,000 depending on system size and location.
Victorian state incentive for commercial systems 30-200 kW. Stacks on top of STCs, adding up to ~$35,000 in additional value.
Annual recurring revenue for systems above 100 kW. Generates income every year based on actual electricity production.

Small-scale Technology Certificates (STCs) are a federal incentive that provides an upfront discount on solar systems up to 100 kW. The number of STCs depends on your location (STC zone), system size, and the deeming period remaining until 2030. Your installer claims the STCs and passes the value to you as a point-of-sale discount.
Victorian Energy Efficiency Certificates (VEECs) are a state-based incentive available only in Victoria for commercial solar systems between 30 kW and 200 kW. They are created under the Victorian Energy Upgrades program (Activity 47A for systems up to 100 kW, Activity 47B for 100-200 kW) and stack on top of the federal certificates: STCs up to 100 kW, LGCs above it.
Large-scale Generation Certificates (LGCs) provide annual revenue for solar systems above 100 kW. Unlike STCs which are a one-time upfront discount, LGCs generate ongoing income based on the electricity your system produces each year. One LGC is created per megawatt-hour of generation.
Yes, for eligible Victorian commercial systems. VEU Activity 47 allows VEECs to be created for a 30-200 kW solar system as well as federal STCs or LGCs on the same install. Systems under 30 kW fall outside Activity 47 and claim STCs only.
