If you live in Raipur, Bilaspur, Bhilai, or any other district in Chhattisgarh, your electricity is managed by the Chhattisgarh State Power Distribution Company Limited (CSPDCL). Over the last few years, the state has become famous for running one of the most generous domestic subsidies in India—the “Bijli Bill Half Yojana.”
Because of this scheme, calculating the exact 1 unit electricity price in Chhattisgarh can be confusing. Your physical bill shows one rate, but the amount you actually pay is cut in half if you stay under a specific consumption limit.
Let’s break down the official FY 2026-27 CSPDCL tariff structure, explain exactly how the 400-unit Half Bill Yojana works, and detail the 8% electricity duty that still applies to your final bill.
The Domestic Tariff Structure (LV-1)
Before any subsidies are applied, CSPDCL uses a standard telescopic slab system for all domestic households. This means your first 100 units are billed at a cheap rate, the next 100 at a slightly higher rate, and so on.
📊 Chhattisgarh Base Domestic Tariff (Before Subsidy)
| Monthly Consumption Slab | Base Energy Rate (per unit) |
|---|---|
| 0 – 100 Units | ₹ 4.10 |
| 101 – 200 Units | ₹ 4.20 |
| 201 – 400 Units | ₹ 5.60 |
| 401 – 600 Units | ₹ 6.60 |
| Above 600 Units | ₹ 8.30 |
If you consume exactly 150 units, your first 100 units are billed at ₹4.10, and the remaining 50 units are billed at ₹4.20. However, you do not actually pay these full rates due to the state subsidy.
How the “Bijli Bill Half Yojana” Works
The Chhattisgarh government introduced the Half Bill scheme to drastically lower electricity costs for lower and middle-class households. Here is how the mathematics of the subsidy works in practice.
If you consume 400 units or less:
If your total monthly consumption stays at or below 400 units, the state government steps in and pays for exactly 50% of your Energy Charges and 50% of your Fixed Charges.
- Your effective rate for the first 100 units drops from ₹4.10 to just ₹2.05.
- Your effective rate for the next 100 units drops from ₹4.20 to just ₹2.10.
- Your fixed charges are also slashed in half.
⚠️ The 401-Unit Danger Cliff
If you consume exactly 400 units, you get the massive 50% discount on your entire bill. But the moment you consume 401 units, the “Half Bill” subsidy rules change. Depending on the exact implementation tier for your district, crossing 400 units can cause you to lose the 50% discount entirely, meaning your bill instantly doubles. Monitoring your meter in summer is absolutely critical in Chhattisgarh.
The Hidden Cost: 8% Electricity Duty
While the state government pays for half of your energy charges, they still collect taxes on the electricity you consume. An 8% Electricity Duty is added to every CSPDCL domestic bill.
It is very important to note that the 8% duty is calculated on your consumption before the Half Bill subsidy is applied. The government does not give you a discount on the taxes.
⚡ Stop Manually Calculating the Subsidy
Applying the telescopic slabs, calculating the 50% energy and fixed charge discount, and adding the 8% duty is mathematically frustrating. Use our free Chhattisgarh electricity bill calculator. Just enter your units, and it instantly calculates your exact CSPDCL bill, automatically applying the Half Bill Yojana if you qualify.
Commercial, Industrial & EV Tariffs
The Bijli Bill Half Yojana is strictly for domestic households. Businesses, factories, and EV charging stations do not qualify for any 50% discounts.
Commercial Shops (Non-Domestic LV-2.1)
Small shops and commercial offices are billed on a steep telescopic structure with high fixed charges per kW.
- 0 to 100 Units: ₹6.30 per unit
- 101 to 400 Units: ₹7.30 per unit
- Above 400 Units: ₹8.70 per unit
- Fixed Charge: ₹50 per kW of sanctioned load per month
Small Industries (LV-5)
Small manufacturing units and workshops operate on a flat-rate billing system to make cost prediction easier for business owners.
- Energy Rate: Flat ₹6.05 per unit
- Fixed Charge: ₹120 per kW per month
EV Charging Stations (LV-2.3)
To promote electric vehicles, public charging stations do not pay any fixed infrastructure charges. They only pay for the energy they use.
- Energy Rate: Flat ₹7.02 per unit
- Fixed Charge: Nil (₹0.00)
3 Strategies to Lower Your CSPDCL Bill
| Strategy | Why it works in Chhattisgarh |
|---|---|
| Defend the 400-Unit Line at All Costs | The 400-unit mark is the most critical boundary in Chhattisgarh. If you consume 395 units, your bill is slashed in half. If you consume 405 units, you risk losing the massive subsidy benefits. During summer, strictly monitor your AC usage to stay under 400 units. |
| Upgrade Old Air Conditioners | Because the penalty for crossing 400 units is so severe, replacing a 10-year-old AC with a 5-star inverter AC has an incredibly fast ROI in Chhattisgarh. It can be the difference between keeping or losing the 50% discount. |
| Pay Online for Rebates | CSPDCL offers small rebates for consumers who pay their bills digitally and on time through their official app or web portal. |
