N93 General Supply Transitional Demand tariff guide
Who this is for
Existing eligible low-voltage business customers transitioning toward the standard demand tariff.
How the bill works
You pay fixed and energy charges. The bill also uses the highest kW demand in set periods.
What solar changes
Solar can reduce daytime grid use. If the billed peak occurs after solar output falls, solar alone will not reduce the demand charge.
What a battery changes
A battery can reduce a billed peak. It needs enough kW and enough charge for the full event.
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.
- Check the battery power in kW against the full peak event.
- Model the tariff that will replace this temporary tariff.
The price signal behind this code
Network rates only. These are not retail electricity prices.
Published network rates

When it applies
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.
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.
