WA businesses benefit from the Federal Small Scale Technology Certificates (STCs) and, for larger arrays, Large Scale Generation Certificates (LGCs). These are applied at the point of sale discount to reduce total cost for solar systems. The rebate amount and buyback rates vary depending on system size, generating capacity, and location in regional WA or metropolitan areas.
Through the Distributed Energy Buyback Scheme (DEBS), synergy customers and horizon power customers receive export payments for surplus electricity sent to the grid. DEBS rates also reward late afternoon exports when electricity demand is highest, helping local councils and businesses support grid stability.
