How Telangana Domestic Electricity Bills Are Calculated
Electricity billing in Telangana is managed by two main state discoms: TGSPDCL (Telangana Southern Power Distribution Company Limited, serving Hyderabad, Rangareddy, Medchal, and southern districts) and TGNPDCL (Northern Power Distribution Company of Telangana Limited). Both follow the retail supply tariff orders issued by the Telangana Electricity Regulatory Commission (TGERC).
The Three Consumption Categories (Category A, B, and C)
Telangana does not use a single progressive slab for all households. Instead, the total monthly units consumed places your meter into one of three distinct categories, dictating the energy rates applied to your blocks:
| Category | Total Monthly Usage | Internal Energy Slab | Energy Rate (Rs./Unit) |
|---|---|---|---|
| Category A | Up to 100 units / month | First 50 units (0 – 50) | Rs. 1.95 |
| Next 50 units (51 – 100) | Rs. 3.10 | ||
| Category B | 101 to 200 units / month | First 100 units (0 – 100) | Rs. 3.40 |
| Next 100 units (101 – 200) | Rs. 4.80 | ||
| Category C | Above 200 units / month | First 200 units (0 – 200) | Rs. 5.10 |
| Next 100 units (201 – 300) | Rs. 7.70 | ||
| Next 100 units (301 – 400) | Rs. 9.00 | ||
| Next 400 units (401 – 800) | Rs. 9.50 | ||
| Above 800 units (> 800) | Rs. 10.00 |
Fixed Charges and Customer Charges
In addition to energy units consumed, domestic electricity bills in Telangana comprise two mandatory structural components:
- Fixed Charges: Billed on your sanctioned load in kilowatts (kW). Under the FY 2026-27 schedule, fixed charges are Rs. 10 per kW per month for consumption up to 800 units, increasing to Rs. 50 per kW per month when consumption exceeds 800 units.
- Customer Charges: A flat monthly fee based on your consumption bracket:
- 0 to 50 units: Rs. 40 per month
- 51 to 100 units: Rs. 70 per month
- 101 to 200 units: Rs. 90 per month
- 201 to 300 units: Rs. 100 per month
- 301 to 400 units: Rs. 120 per month
- 401 to 800 units: Rs. 140 per month
- Above 800 units: Rs. 160 per month
Worked Example: 250 Units on a 2 kW Sanctioned Load
Because 250 units exceeds 200 units, the connection is classified under Category C:
- First 200 units at Rs. 5.10 = Rs. 1,020.00
- Next 50 units (201 to 250) at Rs. 7.70 = Rs. 385.00
- Total Energy Charges: Rs. 1,405.00
- Fixed Charges (2 kW at Rs. 10/kW): Rs. 20.00
- Customer Charges (201–300 unit bracket): Rs. 100.00
- Estimated Subtotal before additional charges: Rs. 1,525.00
Gruha Jyothi Scheme Subsidy Advisory
Eligible households may receive a government subsidy under the Gruha Jyothi scheme, subject to the scheme's applicable eligibility conditions, white ration card verification, and billing rules. This calculator computes the baseline tariff subtotal under the TGERC retail schedule and does not automatically determine individual beneficiary qualification. Check your actual subsidy adjustment and payable dues directly on your official monthly TGSPDCL or TGNPDCL bill invoice.
Frequently Asked Questions (FAQ)
1. What are customer charges on a Telangana electricity bill?
Customer charges are approved monthly service fees levied by distribution companies to cover meter inspection, billing infrastructure, and administrative customer services. They are tiered from Rs. 40 up to Rs. 160 per month depending on your total unit usage.
2. How does crossing 200 units affect my electricity bill in Hyderabad?
Consuming 200 units places you in Category B (where your first 100 units cost Rs. 3.40 and the next 100 cost Rs. 4.80). If consumption rises to 201 units, you shift into Category C, where the initial 200 units jump to Rs. 5.10 per unit and subsequent units cost Rs. 7.70 or more.
3. How do I calculate my bill from my meter reading?
Note the current kWh reading on your digital meter display. Subtract the previous reading printed on your last monthly electricity invoice to determine net units consumed. Enter that figure and your sanctioned load (in kW) into the calculator above.
