South Australia’s New Solar Export Tariff: What You Need to Know
South Australia’s electricity grid is evolving. Originally built for one-way energy flow (from generators to homes), it now supports two-way energy exchange thanks to the state’s world-leading rooftop solar adoption. To ensure fair and sustainable grid access for all, SA Power Networks will introduce an Export Tariff from 1 July 2025.
This guide explains how the tariff works, its impact on bills, and actionable tips to maximize solar savings.

What Is the Solar Export Tariff?
The Export Tariff (or two-way pricing) applies to excess solar energy fed back into the grid during peak congestion periods. Key details:
Who it affects: Residential/small business customers with solar, batteries, or V2G (inverters ≤30kW AC).
How it works: Only exports above a free threshold are charged. The more you self-consume, the less you pay.
Goal: Fund grid upgrades fairly, ensuring non-solar users aren’t disproportionately burdened.
💡 Note: SA Power Networks charges retailers—not customers directly. Your bill impact depends on how your retailer passes costs through.
How the Export Tariff Impacts Your Bill
1. Meter-Specific Rates & Thresholds
2. Estimated Bill Scenarios
Low exporter: Minimal impact (stays under free threshold).
High exporter: Costs rise if exports exceed thresholds during 10 am–4 pm congestion.
4 Ways to Reduce Export Charges & Maximise Solar Savings
1. Shift Energy Use to Daylight Hours
Run high-consumption appliances (e.g., washing machines, EVs, pool pumps) between 10 am–4 pm to use solar directly.
2. Pre-Cool/Heat Your Home
Use solar power to cool or heat your home before peak evening rates.
3. Invest in a Battery
Store excess solar for nighttime use, slashing reliance on the grid.
4. Upgrade to a Smart Meter
Interval meters often have higher free thresholds, reducing charges.

FAQs
Q: Will I pay the tariff if I don’t export solar?
A: No. Only customers exporting above the threshold are affected.
Q: How is the tariff calculated?
A: Based on export volume during congested periods (typically midday).
Q: Can I avoid charges entirely?
A: Yes—by self-consuming more solar or installing a battery.
South Australia’s Export Tariff ensures a fair, future-proof grid while incentivizing smart solar use. By adjusting consumption habits or investing in storage, households can minimise costs and keep enjoying solar benefits.
