N90 General Supply Block tariff guide

Who it’s for

Businesses connected at low voltage using less than 160 MWh a year.

What you pay

You pay a daily charge. The energy rate changes after the site passes a quarterly usage block.

If you get solar

Solar reduces the electricity the site buys. The network gives no special reward for using solar at a set time.

If you get a battery

This tariff gives a battery no clear network target. Check retailer prices, solar exports and backup needs.

Check before you decide

  • Confirm this code on a current retailer bill.
  • Use the retailer prices, not only the network price list.
  • Measure the energy that can move between time periods.
2026–27 network prices

What it costs, and when

These are the network’s charges only. Your retailer adds its own prices on top.

What the network charges

Daily
108.77031 c/day
Block 1
13.83283 c/kWh
Block 2
16.51133 c/kWh

When the rates apply

The second block starts after 30,000 kWh in a quarter.

Illustrative example

Avoid part of the N90 second block

  • A quarter has 130,000 kWh of grid imports.
  • A project removes 10,000 kWh from that quarter.
  • All 10,000 kWh would otherwise be in Block 2.
10,000 kWh × 16.51133 c/kWh ÷ 100$1,651.13 less in the network energy component for that quarter.

This is not a retail-bill saving quote. Check how the retailer passes through network charges.

Would a battery help?

A guide, not a quote

Weak fit

Retailer-led value only

This network tariff does not provide a clear demand or time-window target for a behind-the-meter battery. Any case must come from the retailer spread, solar capture or resilience value.

A battery can reduce these

  • Grid energy purchases where stored solar would otherwise be exported.
  • Retailer time-of-use or wholesale exposure if the retail contract differs from the network structure.

A battery can’t change these

  • Daily access, metering and other fixed charges.
  • A network demand charge that is not present on this tariff.
  • Quarterly block thresholds or closed/transitional tariff rules through dispatch alone.

You’d need to check

  1. Current retailer bill and complete retail rate schedule.
  2. At least 12 months of interval imports and solar exports.
  3. Eligible alternative network and retailer tariffs.
  4. Resilience requirements valued separately from bill savings.
