N90 General Supply Block tariff guide
Who this is for
Businesses connected at low voltage using less than 160 MWh a year.
How the bill works
You pay a daily charge. The energy rate changes after the site passes a quarterly usage block.
What solar changes
Solar reduces the electricity the site buys. The network gives no special reward for using solar at a set time.
What a battery changes
This tariff gives a battery no clear network target. Check retailer prices, solar exports and backup needs.
Check before you model
- 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.

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.
