Time-of-Day Tariff (TOD) in Electricity Billing
Learn how time-of-day tariff changes electricity cost by peak and off-peak usage windows.
Quick Answer
Time-of-day tariff bills electricity at different rates for peak and off-peak periods, so usage timing can materially affect monthly cost.
Key Points
- Peak windows are usually priced higher than off-peak windows.
- Shifting discretionary loads can reduce effective average unit rate.
- TOD impact is higher for homes or businesses with concentrated evening load.
- Check provider policy because TOD rules are utility-specific.
Examples
Load shifting benefit
Running non-urgent high-load tasks outside peak window can reduce monthly payable amount.
No-shift scenario
If most use stays in peak slots, effective cost per unit rises even without large unit growth.
