  • Benchmark period: 2026-07-01 to 2027-06-30. Benchmarks guide comparisons; retailers are not required to pay them. Your retailer may use different time windows.
  • Time-of-day benchmarks already incorporate network export charges and rebates. Do not deduct those again from these benchmark values. Actual retail plan terms may differ.
  • All entered exports must cover the same period. This estimates export credits only; compare import rates, daily charges, conditions and fees for the whole plan.

How it works

For each endpoint, multiply exports in each network window by its benchmark rate, sum, then divide by total exports. Credit in AUD = kWh × cents/kWh ÷ 100. The separate 2026–27 all-day range is 3.4–6.5 c/kWh. These are benchmarks, not mandatory payments.

Use exports, not total solar generation. Enter all windows for the same period, using local network time windows. Do not subtract export charges from the benchmark again: IPART already includes network export tariffs. Results show rates to three decimals and money to cents; intermediate values are not rounded.

All-day mode needs only total exports and your flat offer. Advanced modes retain separate quantities for each network and require all four windows. Worked allocations below are illustrative, not typical export profiles.

Worked examples

Ausgrid mixed exports

An illustrative Ausgrid allocation of 800 kWh from 10 am–3 pm, 100 from 3–4 pm and 100 from 4–9 pm gives (800 × 3.9 + 100 × 4.8 + 100 × 17.2) ÷ 1,000 = 5.32 c/kWh at the lower endpoint; upper endpoint is 5.92. Value is AUD 53.20–59.20. An illustrative 5c all-day offer pays AUD 50.

Essential evening exports

100 kWh entirely from 5–8 pm gives 26.6–33.3 c/kWh, or AUD 26.60–33.30. The all-day benchmark for those 100 kWh is AUD 3.40–6.50.

Frequently asked questions

Must my retailer pay the benchmark?
No. NSW retailers set their own feed-in offers.
Is a higher feed-in rate always a better plan?
No. Compare import rates, supply charges, fees and conditions too.
Can I use another network’s windows?
No. Choose your own network and enter quantities for its exact windows. Each network retains separate values; changing networks never transfers an allocation.
What period does this cover?
The benchmark year is 1 July 2026 through 30 June 2027. Enter exports for any consistent period within it.
