Under the service-based tariff framework, Bands A to E correspond to minimum daily supply levels. NERC’s FAQ describes A as at least 20 hours, B 16, C 12, D 8 and E 4; confirm the current classification on your bill or vending receipt.
A band is a service classification, not a promise that every individual day will be identical. Regulatory oversight and tariff orders are also changing as state electricity markets take effect.
The essentials
- The band and feeder printed on the bill.
- The tariff shown on the latest receipt.
- A dated supply log if service consistently misses the band level.
- Whether your state has transitioned to a state regulator.
What to check first
Start with the evidence already in front of you. A precise account, meter, product or safety detail is more useful than guessing from the outcome alone.
- The band and feeder printed on the bill.
- The tariff shown on the latest receipt.
- A dated supply log if service consistently misses the band level.
- Whether your state has transitioned to a state regulator.
Step by step
Work through the existing transaction, account or installation in order. Keep the reference and result from each step before moving to the next.
- Confirm the band from the current bill or distributor channel.
- Record actual supply periods over a meaningful date range.
- Raise a written service-quality complaint with the DisCo if needed.
- Use the regulator currently responsible for your state for escalation.
Mistakes to avoid
These shortcuts often turn a traceable problem into a second payment, a lost evidence trail or a safety risk.
- Assuming every feeder in a neighbourhood has the same band.
- Using an old tariff figure after a new order.
- Reporting service quality without dates, feeder details or outage periods.
When to escalate
Attach the bill showing the feeder and band, plus a dated supply log and the DisCo complaint acknowledgement. This makes the service-level issue easier to assess.
Frequently asked
Does Band A mean 24-hour electricity?
No. NERC’s general FAQ describes Band A as a minimum of 20 hours of supply per day under the service-based framework, not uninterrupted 24-hour supply.
Where can I see my tariff band?
It should be shown on the electricity bill; prepaid customers can also check the vending receipt or verified distributor channel.
