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
- kW capacity charge (set by your highest half-hour in the last 12 months)
Solar and battery
The capacity charge looks back 12 months, so one big day can set it for a year. A battery that flattens spikes protects you twice over.
Worth asking about
Energy rates drop but the capacity charge arrives. Worth it for steady loads, risky for spiky ones.

EA302 LV 100–160 MWh
Who it’s for
Low-voltage sites using 100–160 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.
2026–27 network prices
What it costs, and when
These are the network’s charges only. Your retailer adds its own prices on top.
Peak is 3pm–9pm on working weekdays, November–March and June–August only.

- 653.3697 c/day
- Peak energy
- 8.8231 c/kWh
- Off-peak energy
- 1.9685 c/kWh
- Peak capacity
- 48.3397 c/kW/day
When the rates apply
3pm–9pm on working weekdays in November–March and June–August. All other times.
Illustrative example
Lower EA302 capacity by 50 kW
- The new rolling maximum is 50 kW lower.
- The lower value applies for 365 charge days.
- Other charges do not change.
50 kW × 48.3397 c/kW/day × 365 days ÷ 100Illustrative network-charge reduction: $8,822.00 a year, excluding GST.This tariff uses the highest qualifying half-hour in the previous 12 months. One lower peak does not remove an earlier maximum.
Would a battery help?
A guide, not a quote
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.
Questions about medium business tariffs.
Short answers to the things people ask before they change a tariff.
What is EA302?
EA302 is the Ausgrid LV 100–160 MWh tariff. It is a available low voltage tariff for Low-voltage sites using 100–160 MWh a year. Metering and access charges, peak/off-peak energy and a kW capacity charge.
Can solar or a battery reduce a medium business bill?
The capacity charge looks back 12 months, so one big day can set it for a year. A battery that flattens spikes protects you twice over. For EA302, the battery signal is strong: 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.
How do the medium business network charges work?
The charges are Daily access, Time-of-use energy, kW capacity charge (set by your highest half-hour in the last 12 months). 3pm–9pm on working weekdays in November–March and June–August. All other times. Energy rates drop but the capacity charge arrives. Worth it for steady loads, risky for spiky ones.
Which Ausgrid medium business code applies to my site?
Sites growing past 100 MWh a year. The code on your retailer bill is the starting point. Your retailer must confirm any tariff assignment or change.
Are these network prices or retail prices?
Effective 1 July 2026 to 30 June 2027. Published network prices exclude GST. These are the network charges only. Your retailer adds its own prices and may package the structure differently.
