Understanding commercial electricity tariff components
Commercial electricity tariffs are structured into three primary components that businesses need to understand for effective energy management:
1. Fixed/Demand Charges
These charges are based on the maximum power requirement (measured in kVA or kW) that a business facility might need. The demand charge is calculated on either:
- Contract demand: The power capacity agreed upon in the connection agreement
- Actual demand: The highest power drawn during a billing cycle
2. Energy Charges
This component is based on actual electricity consumption measured in kilowatt-hours (kWh). Energy charges often follow a slab system where rates increase with higher consumption levels. They might also vary based on:
- Time of day (ToD) usage
- Seasonal variations
- Voltage levels
3. Additional Surcharges
These include various additional components such as:
- Fuel cost adjustment charges
- Regulatory charges
- Electricity duty
- Power factor penalties/incentives
India-specific context
The commercial electricity tariff landscape in India is diverse and varies significantly across states. Here’s a comprehensive breakdown of state-specific implementations:
State-wise Tariff Structures
- Maharashtra
- Implements mandatory ToD tariffs for commercial consumers above 20 kW
- Offers power factor incentives for maintaining above 0.95
- Special rebates for IT parks and data centers
- Load factor incentives for consistent power usage
- Karnataka
- Progressive slab system with 4 consumption brackets
- Special night-time consumption incentives (10 PM – 6 AM)
- Solar rooftop integration benefits
- Additional charges for peak hour usage (6 PM – 10 PM)
- Gujarat
- Separate tariffs for shopping malls and commercial complexes
- Premium tariff for 24/7 power supply guarantee
- Special provisions for seasonal businesses
- Green energy incentives for renewable adoption
- Tamil Nadu
- Voltage-wise tariff differentiation
- Special provisions for educational institutions
- Door-number based billing for commercial complexes
- Seasonal time-of-day variations
Practical applications
Understanding these components helps businesses in:
- Optimizing demand charges through load management
- Planning operations during off-peak hours
- Implementing power factor correction measures
- Budgeting and forecasting energy costs

Frequently Asked Questions (FAQs)
How is maximum demand calculated in commercial tariffs?
Maximum demand is typically measured in 15-minute intervals throughout the billing cycle, with the highest reading being used for billing purposes.
Can businesses change their contract demand?
Yes, businesses can request changes in contract demand, but it usually requires advance notice and approval from the electricity distribution company.
What is the significance of power factor in commercial tariffs?
Power factor affects overall efficiency and costs. Most states mandate a minimum power factor of 0.9 and impose penalties for non-compliance.
