1. Our assignment policy does not allow customers to opt-out of the small customer export tariff from 1 July 2025. This ensures that customers are paying for the Ausgrid services they use. Similarly, we do not allow customers to opt-out of consumption charges. As our export pricing structure includes charges and rewards, customers who respond to these price signals (e.g. by installing a battery or adopting behavioural changes to shift their consumption profile) will have the opportunity to reduce their exposure to export charges and increase the opportunity to receive export rewards. Further, we expect it is likely our export charges for the 2024-29 will be lower than the feed-in tariffs customers receive from retailers. Therefore, in practice, it is likely customers will perceive these export charges as a reduction in their feed-in tariff, rather than a charge to export.

   The revenue recovered for the export tariff will be lower than the attributable costs of export services.41

so what we have is not the retail FiT but the rate charged to retailers.

retailers will decide what FiT they can afford to pay small scale (residential) electricity exporters.
