N93 General Supply Transitional Demand tariff guide

Who it’s for

Existing eligible low-voltage business customers transitioning toward the standard demand tariff.

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.
  • Model the tariff that will replace this temporary tariff.
2026–27 network prices

What it costs, and when

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

N93 in one day

Solar soak runs every day. Peak is business days only.

What the network charges

Daily
108.77031 c/day
Solar soak
5.68656 c/kWh
Other energy
14.66333 c/kWh
High-season demand
23.936 c/kW/day
Low-season demand
11.803 c/kW/day

When the rates apply

Solar soak is 10:00–14:00 every day. Peak is 16:00–20:00 on business days. Demand is set from the highest 30-minute kW reading in the peak period. High season is November–March. Low season is April–October.

Illustrative example

Reduce an N93 summer demand peak

  • The project cuts the billed peak by 50 kW.
  • The reduction holds for the full 30-minute peak interval.
  • The month has 31 days.
  • Use the N93 high-season network rate.
50 kW × 23.936 c/kW/day × 31 days ÷ 100$371.01 difference in the N93 network demand component for that month.

A later peak can set a new billed maximum. This is not a retail saving. Confirm the transition path and retailer pass-through.

Would a battery help?

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

  1. At least 12 months of interval data, including every billed maximum.
  2. Demand timestamps, seasonal windows and billing reset rules.
  3. Battery power and duration tested against the full peak event.
  4. Retailer rates plus the network tariff—not a blended cents-per-kWh assumption.
