EA315 LV Above 750 MWh — Embedded Network tariff guide

Who this is for

Main connections for embedded networks at low voltage using more than 750 MWh a year.

How the bill works

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

What solar changes

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.

What a battery changes

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

Check before you model

  • 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.
  • Use data from the embedded network parent meter.

Illustrative example

Lower EA315 embedded-network capacity by 50 kVA

  • This is an embedded-network parent connection above 750 MWh a year.
  • The new rolling maximum is 50 kVA lower.
  • The lower value applies for 365 charge days.
50 kVA × 70.8275 c/kVA/day × 365 days ÷ 100Illustrative network-charge reduction: $12,926.02 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. Use the parent-meter load, not one tenant load.

Strong fit

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.

What dispatch can affect

  • 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.

What it cannot erase

  • 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.

Evidence required

  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.
