What this family covers.
These codes share a charging method. The differences are in the rates, the time bands and who each code is for.
What is on the bill
- Daily access
- Time-of-use energy
- Peak demand charge (N92/N93 only)
Solar and battery
Solar cuts your daytime units, which are the dearer ones. A battery matters most on N92 and N93, where flattening your peak also cuts the demand charge.
Worth asking about
Most sites sit on N91, the default. Steady usage? Ask about N90’s block rates. Predictable 4–8pm peak? Ask about N92/N93. Your retailer decides, so ask them.

N90General Supply BlockBusinesses connected at low voltage using less than 160 MWh a year.
N90 General Supply Block
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.

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.

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
- Current retailer bill and complete retail rate schedule.
- At least 12 months of interval imports and solar exports.
- Eligible alternative network and retailer tariffs.
- Resilience requirements valued separately from bill savings.
N91General Supply Seasonal Time of UseBusinesses connected at low voltage, generally below 160 MWh a year.
N91 General Supply Seasonal Time of Use
Who it’s for
Businesses connected at low voltage, generally below 160 MWh a year.
What you pay
You pay different energy rates at different times. Check the current time periods and seasonal rules.
If you get solar
Solar reduces grid use while it is generating. Its value depends on the energy rate at that time.
If you get a battery
A battery can move energy to a more expensive period. Use actual retailer prices and allow for battery losses.
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.

Conditional fit
Time-of-use load shifting
The tariff provides a time-window signal rather than a demand target. Battery value depends on a repeatable price spread, sufficient cycling volume and a control system that preserves energy for the expensive window.
A battery can reduce these
- Peak-period grid imports shifted into a cheaper network or retailer window.
- Solar generation carried into later business load.
- Retailer energy exposure where its time periods align with battery dispatch.
A battery can’t change these
- Daily access, metering and other fixed charges.
- A network demand charge where none is included in this tariff.
- Energy already consumed directly from solar without incurring battery losses.
You’d need to check
- At least 12 months of interval usage and export data grouped by tariff window.
- Both retailer and network time periods and rates.
- Solar production, operating hours and seasonal load changes.
- Round-trip efficiency, usable capacity, cycling and degradation assumptions.
N92General Supply DemandEligible businesses connected at low voltage using less than 160 MWh a year.
N92 General Supply Demand
Who it’s for
Eligible businesses connected at low voltage using less than 160 MWh a year.
What you pay
You pay fixed and energy charges. The bill also uses the highest kW demand in set periods.
If you get solar
Solar can reduce daytime grid use. If the billed peak occurs after solar output falls, solar alone will not reduce the demand charge.
If you get a battery
A battery can reduce a billed peak. It needs enough kW and enough charge for the full event.
Check before you decide
- Confirm this code on a current retailer bill.
- Use 12 months of interval data. Check the time of each billed peak.
- Check the battery power in kW against the full peak event.

When the rates apply
Demand is set by the highest 30-minute reading from 4pm–8pm on a business day.
Illustrative example
Reduce an N92 summer demand peak
- The project cuts the billed peak by 50 kW.
- The reduction holds for the full 30-minute peak interval.
- The month has 31 days.
- Use the N92 high-season rate.
50 kW × 26.598 c/kW/day × 31 days ÷ 100$412.27 difference in the N92 network demand component for that month.A later peak can set a new billed maximum. N93 has a different rate.

Strong fit
Peak-demand shaving
A recurring peak inside the tariff demand window is a direct battery target. The case weakens if the maximum is rare, unpredictable or longer than the battery can sustain.
A battery can reduce these
- The highest measured kW inside the tariff demand window.
- Peak-period grid energy when the battery discharges at the same time.
- Solar spill that can be stored without sacrificing the required peak reserve.
A battery can’t change these
- Daily access, metering and other fixed charges.
- A peak outside the defined demand window where the tariff does not count it.
- A new maximum created after the battery empties or misses dispatch.
You’d need to check
- At least 12 months of interval data, including every billed maximum.
- Demand timestamps, seasonal windows and billing reset rules.
- Battery power and duration tested against the full peak event.
- Retailer rates plus the network tariff—not a blended cents-per-kWh assumption.

N93 General Supply Transitional Demand
Who it’s for
Existing eligible low-voltage business customers transitioning toward the standard demand tariff.
What you pay
You pay fixed and energy charges. The bill also uses the highest kW demand in set periods.
If you get solar
Solar can reduce daytime grid use. If the billed peak occurs after solar output falls, solar alone will not reduce the demand charge.
If you get a battery
A battery can reduce a billed peak. It needs enough kW and enough charge for the full event.
Check before you decide

Questions about small business tariffs.
Short answers to the things people ask before they change a tariff.
What is N90?
N90 is the Endeavour Energy General Supply Block tariff. It is a available low voltage tariff for Low-voltage non-residential sites using less than 160 MWh a year. Daily access plus two quarterly energy blocks, split at 30,000 kWh per quarter.
What is N91?
N91 is the Endeavour Energy General Supply Seasonal Time of Use tariff. It is a default low voltage tariff for Low-voltage non-residential sites, generally below 160 MWh a year. Daily access plus high-season peak, low-season peak, solar-soak and off-peak energy rates.
What is N92?
N92 is the Endeavour Energy General Supply Demand tariff. It is a optional low voltage tariff for Eligible low-voltage non-residential sites using less than 160 MWh a year. Daily access, solar-soak and other energy rates, plus seasonal peak demand charges in kW.
What is N93?
N93 is the Endeavour Energy General Supply Transitional Demand tariff. It is a transitional low voltage tariff for Existing eligible low-voltage business customers transitioning toward the standard demand tariff. Daily access, solar-soak and other energy rates, plus transitional seasonal peak demand charges in kW.
What is N89?
N89 is the Endeavour Energy LV Seasonal TOU Transitional tariff. It is a transitional low voltage tariff for Selected sites above 160 MWh that meet N19 criteria but lack demand-capable metering. Daily access plus seasonal peak and off-peak energy rates, without the N19 demand component.
Can solar or a battery reduce a small business bill?
Solar cuts your daytime units, which are the dearer ones. A battery matters most on N92 and N93, where flattening your peak also cuts the demand charge. For N90, the battery signal is weak: 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.
How do the small business network charges work?
The charges are Daily access, Time-of-use energy, Peak demand charge (N92/N93 only). The second block starts after 30,000 kWh in a quarter. Most sites sit on N91, the default. Steady usage? Ask about N90’s block rates. Predictable 4–8pm peak? Ask about N92/N93. Your retailer decides, so ask them.
Which Endeavour Energy small business code applies to my site?
Most Endeavour Energy small businesses: workshops, shops, small warehouses. The code on your retailer bill is the starting point. Your retailer must confirm any tariff assignment or change.
