N19 Low Voltage Seasonal TOU Demand tariff guide

Who this is for

Businesses connected at low voltage using more than 160 MWh a year with interval and demand metering.

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.

The price signal behind this code

Network rates only. These are not retail electricity prices.

Published network rates

Low-season peak

When it applies

Peak is 16:00–20:00 on business days. All other times are off-peak. The same clock times apply in standard time and daylight saving time. Demand is set from the highest 30-minute kVA reading in the peak period.

Illustrative example

Reduce an N19 summer kVA peak

  • The billed peak falls by 50 kVA.
  • The reduction holds for the full 30-minute peak interval.
  • The month has 31 days.
  • Use the N19 high-season network rate.
50 kVA × 58.421 c/kVA/day × 31 days ÷ 100$905.53 difference in the N19 network demand component for that month.

A later peak can set a new maximum. Check power factor. This is not a retail saving.

Tariff screen—not a savings 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.

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.
