What is a feed-in tariff — and can my supplier lower it?
The feed-in tariff is what you get for solar power above your consumption. Suppliers set their own rate — but must comply with the Energy Act. Here is what applies.
Beyond 100% net-metering (after 2027 or when feed-in exceeds consumption) you receive a "feed-in tariff" — typically cents per kWh. Until 2024 this was around 7-12 c/kWh; since the 2023-2024 market imbalance many suppliers use tiered rates or a feed-in-cost surcharge for high-export PV installations. A reduction during a fixed-term contract is not permitted without giving you a no-cost cancellation right (Energy Act 2024 art. 7). Outside contract the supplier may change the rate with at least 30 days notice. A feed-in-cost surcharge is only permitted if transparent and cost-based.
