BHND3AO HV Business Demand tariff guide

Who it’s for

Businesses connected and metered at high voltage.

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.
  • Get an engineering review before you select equipment.
2026–27 network prices

What it costs, and when

These are the network’s charges only. Your retailer adds its own prices on top.

BHND3AO in one day

Weekdays only — weekends are all off-peak.

What the network charges

Access
$27.4319/day
Peak energy
5.2283 c/kWh
Shoulder energy
4.2238 c/kWh
Off-peak energy
3.4717 c/kWh
Peak demand
$11.5026/kVA/month
Shoulder demand
$10.4071/kVA/month
Off-peak demand
$3.1143/kVA/month

When the rates apply

On weekdays, off-peak is 12am–7am, shoulder is 7am–10am, peak is 10am–3pm, shoulder is 3pm–5pm, peak is 5pm–8pm, shoulder is 8pm–10pm, and off-peak is 10pm–12am. Weekends are off-peak. Interval meters use daylight saving time. Each band has its own monthly half-hour kVA maximum.

Illustrative example

Reduce the HV peak maximum by 50 kVA

  • The peak-band maximum falls by 50 kVA.
  • No later peak replaces it.
  • The example excludes retailer and project costs.
The peak demand charge falls by about $575.13 for that month: 50 × $11.5026.

The tariff is only one part of an HV project. Engineering and connection costs can control the result.

Would a battery help?

A guide, not a quote

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.

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.
