Module C: Formula & Methodology Behind the Calculator
Our calculator uses the official Pondicherry electricity tariff structure with precise mathematical calculations. Here’s the detailed methodology:
1. Slab-Wise Tariff Structure (Domestic Consumers)
| Slab (Units per month) | Rate per Unit (₹) | Single Phase | Three Phase |
|---|---|---|---|
| 0-100 | ₹1.50 | ✓ | ✓ |
| 101-200 | ₹2.00 | ✓ | ✓ |
| 201-500 | ₹3.50 | ✓ | ✓ |
| 501-800 | ₹4.60 | ✓ | ✓ |
| 801 and above | ₹6.60 | ✓ | ✓ |
2. Calculation Formula
The total electricity bill is calculated using this comprehensive formula:
Total Bill = (Energy Charges) + (Fixed Charges) + (Fuel Adjustment Charge) + (Electricity Duty)
Where:
- Energy Charges = Σ (Units in slab × Rate for that slab)
- Fixed Charges = As entered by user (typically ₹50 for domestic)
- Fuel Adjustment Charge = Total Units × Fuel Adjustment Rate (₹0.15/unit)
- Electricity Duty = 5% of (Energy Charges + Fixed Charges + Fuel Adjustment Charge)
3. Special Considerations
- Minimum Bill: For consumers with very low consumption, a minimum bill of ₹50 is applied
- Solar Net Metering: For consumers with solar panels, the net consumption (units consumed – units generated) is used for calculation
- Time-of-Day Tariff: Some commercial consumers may have different rates for peak and off-peak hours
- Demand Charges: Industrial consumers may have additional demand charges based on their maximum load

Module G: Interactive FAQ – Your Pondicherry Electricity Bill Questions Answered
How often does Pondicherry update its electricity tariff rates?
The Pondicherry Electricity Department typically reviews and updates tariff rates annually, with revisions usually announced in April each year. However, fuel adjustment charges may be revised quarterly based on coal and gas price fluctuations. Major tariff structure changes usually occur every 3-5 years after public consultations.
You can check the latest official rates on the Pondicherry government website or through our calculator which is updated within 48 hours of any official announcement.
What’s the difference between single phase and three phase connections?
Single Phase (230V):
- Suitable for most household appliances
- Typical for homes with load up to 5 kW
- Lower installation and maintenance costs
- Limited to smaller motors and appliances
Three Phase (415V):
- Required for high-power appliances and machinery
- Typical for commercial/industrial setups
- More efficient for loads above 7.5 kW
- Allows for smaller, more efficient wiring
- Can power three-phase motors directly
Most residential consumers in Pondicherry use single phase connections unless they have special requirements like large workshops or multiple high-power appliances.
How is the fuel adjustment charge calculated and why does it change?
The fuel adjustment charge (FAC) is a variable component that accounts for fluctuations in the cost of fuel (primarily coal and gas) used for electricity generation. It’s calculated as:
Fuel Adjustment Charge = Total Units Consumed × Current FAC Rate
The FAC rate changes quarterly based on:
- Global coal and gas price movements
- Exchange rate fluctuations (for imported fuel)
- Transportation and handling costs
- Power purchase agreements with generating companies
For domestic consumers in Pondicherry, the FAC typically ranges between ₹0.10 to ₹0.20 per unit, while commercial consumers may see rates up to ₹0.25 per unit during periods of high fuel costs.
