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.

Who it is for

Large and very large low-voltage sites. EA314/EA315 are the embedded-network parent versions.

What is on the bill

  • Daily access
  • Time-of-use energy
  • kVA capacity charge

Solar and battery

Solar trims energy. A battery helps the kVA charge only partly — kVA includes reactive power, so fix power factor first.

The codes in detail.

Open a code for its exact rates, the charge window, a worked example and the checks worth running before you change anything.

EA305LV 160–750 MWh — SystemBusinesses connected directly to the low-voltage network using 160–750 MWh a year.Available · Low voltage

EA305 LV 160–750 MWh — System

Who it’s for

Businesses connected directly to the low-voltage network using 160–750 MWh a year.

What you pay

You pay fixed and energy charges. The bill also uses the highest kVA reading in set periods.

If you get solar

Solar can reduce daytime grid use. If the highest kVA reading occurs after solar output falls, solar alone will not remove it. Solar does not correct poor power factor.

If you get a battery

A battery can reduce the active-power part of the kVA peak. Check power factor before you size it.

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.
  • Get kW, kVA and power-factor data from the billing meter.

Illustrative example

Lower EA305 capacity by 50 kVA

  • The new rolling maximum is 50 kVA lower.
  • The lower value applies for 365 charge days.
  • Other charges do not change.
50 kVA × 57.7962 c/kVA/day × 365 days ÷ 100Illustrative network-charge reduction: $10,547.81 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. A 50 kW battery does not guarantee a 50 kVA reduction.

Peak-kVA control

A controlled battery may reduce the site maximum, but the bill is based on apparent power. Power factor and reactive load can be as important as battery kW.

A battery can reduce these

  • The active-power contribution to the measured kVA maximum.
  • 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.
  • Reactive-power demand unless the inverter and control design explicitly provide power-factor support.
  • A new maximum created after the battery empties or misses dispatch.

You’d need to check

  1. At least 12 months of interval data, including every billed maximum.
  2. Demand timestamps, seasonal windows and billing reset rules.
  3. kW, kVA, kvar and power-factor data at the billing meter.
  4. Retailer rates plus the network tariff—not a blended cents-per-kWh assumption.

Questions about large business tariffs.

Short answers to the things people ask before they change a tariff.

What is EA305?

EA305 is the Ausgrid LV 160–750 MWh — System tariff. It is a available low voltage tariff for System-connected low-voltage sites using 160–750 MWh a year. Daily access, peak/off-peak energy and a kVA capacity charge.

What is EA314?

EA314 is the Ausgrid LV 160–750 MWh — Embedded Network tariff. It is a available low voltage tariff for Embedded-network parent connections at low voltage using 160–750 MWh a year. Daily access, peak/off-peak energy and embedded-network kVA capacity pricing.

What is EA310?

EA310 is the Ausgrid LV Above 750 MWh — System tariff. It is a available low voltage tariff for System-connected low-voltage sites using more than 750 MWh a year. Higher daily access, peak/off-peak energy and a kVA capacity charge.

What is EA315?

EA315 is the Ausgrid LV Above 750 MWh — Embedded Network tariff. It is a available low voltage tariff for Embedded-network parent connections at low voltage using more than 750 MWh a year. Higher daily access, peak/off-peak energy and embedded-network kVA capacity pricing.

Can solar or a battery reduce a large business bill?

Solar trims energy. A battery helps the kVA charge only partly — kVA includes reactive power, so fix power factor first. For EA305, the battery signal is strong: A controlled battery may reduce the site maximum, but the bill is based on apparent power. Power factor and reactive load can be as important as battery kW.

How do the large business network charges work?

The charges are Daily access, Time-of-use energy, kVA capacity charge. 3pm–9pm on working weekdays in November–March and June–August. All other times.

Which Ausgrid large business code applies to my site?

Large and very large low-voltage sites. EA314/EA315 are the embedded-network parent versions. 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.
