State tariff guide
Telangana industrial electricity tariff: HT-I(A) and LT-III.
Every line on a TGSPDCL or TGNPDCL factory bill, from TGERC’s retail supply tariff at the 2026-27 rates. Then a worked bill for a 500 kVA plant at 11 kV, what one demand spike above contract demand adds, and what the morning and evening peaks cost.
Who this page covers
Telangana has two distribution companies, TGSPDCL (Southern Power Distribution Company of Telangana, which includes Hyderabad) and TGNPDCL (Northern Power Distribution Company of Telangana), plus the Co-operative Electric Supply Society in Sircilla. All three bill on one retail supply tariff set by the Telangana Electricity Regulatory Commission (TGERC). It applies from 1 April 2026 to 31 March 2027.
Industry is billed under two schedules:
- HT-I(A) Industry: supply at 11 kV, 33 kV, or 132 kV and above, with demand charges per kVA of contracted demand.
- LT-III Industry: low-tension supply up to a contracted load of 75 kW (100 HP), or 93 kW (125 HP) for rice mills, with fixed charges per kW.
HT rates for 2026-27
| HT category and voltage | Energy charge | Demand charge, a month |
|---|---|---|
| HT-I(A) industry general, 11 kV | ₹7.65 per kVAh | ₹500 per kVA |
| HT-I(A) industry general, 33 kV | ₹7.15 per kVAh | ₹500 per kVA |
| HT-I(A) industry general, 132 kV and above | ₹6.65 per kVAh | ₹500 per kVA |
| HT-I(A) optional category, up to 150 kVA at 11 kV | ₹8.00 per kVAh | ₹100 per kVA |
| HT-I(A) seasonal industries, 11 / 33 / 132 kV | ₹8.60 / ₹7.90 / ₹7.70 | ₹500 per kVA |
| HT-I(B) ferro alloys, 11 / 33 / 132 kV | ₹7.65 / ₹7.15 / ₹6.65 | ₹500 per kVA |
| HT-II(A) others (commercial), 11 / 33 / 132 kV | ₹8.80 / ₹8.00 / ₹7.80 | ₹500 per kVA |
Lights and fans on an HT-I(A) service pay the same energy rates as the industry, and colony consumption pays ₹7.30 at every voltage. On top, every HT service pays a customer charge of ₹2,000 a month at 11 kV, ₹3,500 at 33 kV and ₹5,000 at 132 kV and above.
The optional category has a far lower demand charge, ₹100 per kVA against ₹500. For a 120 kVA plant at 110 kVA of demand using 30,000 kVAh a month, it comes to about ₹2,53,000 against about ₹2,91,500 on industry general, even after its higher energy rate and the time-of-day rebate it does not get.
LT-III industry rates
| LT-III sub-category | Energy charge | Fixed charge, a month |
|---|---|---|
| Industries | ₹7.70 per unit | ₹100 per kW |
| Seasonal industries, off-season | ₹8.40 per unit | ₹100 per kW |
| Mushroom, rabbit, sheep and goat farms | ₹7.30 per unit | ₹100 per kW |
| Poultry farms | ₹7.00 per unit | ₹65 per kW |
| Pisciculture, prawn culture and sugarcane crushing | ₹6.20 per unit | ₹50 per kW |
The LT-III customer charge goes by load: ₹100 a month up to 20 HP, ₹350 from 21 to 50 HP and ₹1,200 from 51 to 125 HP. LT-III has no time-of-day tariff. A seasonal LT-III industry pays its fixed charge of ₹100 per kW on 30% of contracted load; a seasonal HT industry pays demand charges on 30% of contracted demand or the recorded demand, whichever is higher.
Billing demand and the minimum energy charge
On HT, the demand charge is on the higher of the maximum demand recorded in the month and 80% of contracted demand. A 500 kVA plant pays for at least 400 kVA every month, ₹2,00,000 at ₹500. At 470 kVA it pays for 470 kVA.
There is also a minimum energy charge: industry is billed for at least 50 kVAh per kVA of billing demand a month. At 470 kVA of billing demand, that is 23,500 kVAh; a month that uses fewer is billed as if it used 23,500.
Maximum demand above contracted demand
When recorded maximum demand goes above contracted demand, two things happen. The demand above contracted demand is billed at two times the normal demand charge, ₹1,000 per kVA on HT-I(A). And from 120% upwards, the energy charge on every unit of the month goes up too:
| Maximum demand, as a share of contracted demand | Demand charge on the excess | Energy charge on all units |
|---|---|---|
| Above 100% up to 120% | Two times the normal rate | Normal |
| Above 120% up to 200% | Two times the normal rate | 1.15 times normal |
| Above 200% | Two times the normal rate | 1.20 times normal |
The MD penalty guide explains how one spike sets a whole month’s charge.
Time of day
Time of day applies to HT-I(A) industry general and poultry farms, HT-II commercial, HT-III airports and stations, and HT-IX EV charging stations. It is not listed for the optional category or for any LT category.
| Hours | Over the normal energy charge |
|---|---|
| 6 am – 10 am and 6 pm – 10 pm | ₹1.50 per kVAh more |
| 10 am – 6 pm | ₹0.50 per kVAh less |
| 10 pm – 6 am | Normal rate |
The same rates apply in every month. Every kVAh moved from a peak hour into the 10 am – 6 pm window saves ₹2.00.
kVAh billing and power factor
HT energy is billed in kVAh, and the tariff levies no low power factor surcharge wherever kVAh billing is done: a low power factor raises the units themselves. A plant that uses 1,35,000 kWh at a power factor of 0.90 is billed for 1,50,000 kVAh. At 0.98 it would be billed for about 1,37,755 kVAh, about ₹94,000 less a month at ₹7.65. The kVAh billing guide explains the difference.
On LT, a capacitor surcharge of 25% of the bill applies to LT-III loads below 13 HP if the capacitors are found not working.
Other lines on the bill
- FSA (fuel surcharge adjustment) is added per unit under TGERC Regulation 2 of 2023 and changes over the year. Take the current figure from your bill.
- Green tariff: ₹0.66 per unit over the normal tariff, only for consumers who opt for it.
- Late payment: on HT, a delayed payment surcharge of 5 paise per ₹100 a day, at least ₹550 a month. On LT-III, 5 paise per ₹100 a day, at least ₹150.
Electricity duty is charged on top under the Telangana Electricity Duty Act, 1939; take its rate from your latest bill. It is not part of the TGERC tariff.
Worked example: a 500 kVA plant at 11 kV
An illustrative HT-I(A) general industry at 11 kV with a contracted demand of 500 kVA. Its maximum demand is 470 kVA, and it uses 1,50,000 kVAh in the month: 40,000 in the peak hours, 70,000 from 10 am to 6 pm and 40,000 at night.
| Bill line | Working | Amount |
|---|---|---|
| Demand charge | 470 kVA × ₹500 (above 80% of 500 kVA) | ₹2,35,000 |
| Energy charge | 1,50,000 kVAh × ₹7.65 | ₹11,47,500 |
| Peak-hour charge | 40,000 kVAh × ₹1.50 | ₹60,000 |
| Day rebate | 70,000 kVAh × ₹0.50 | −₹35,000 |
| Customer charge | 11 kV | ₹2,000 |
| Before FSA and electricity duty | About ₹9.40 per kVAh | ₹14,09,500 |

What one demand spike costs
Suppose the same plant has one bad 30-minute block, say several heavy motors restarting together after a power cut, and maximum demand reaches 560 kVA. The demand charge goes up to the full 500 kVA, ₹15,000 more, and the 60 kVA above contracted demand pays ₹1,000 each, ₹60,000. The bill goes from ₹14,09,500 to ₹14,84,500: ₹75,000 more.
If the spike reaches 620 kVA, 124% of contracted demand, the excess demand costs ₹1,20,000 and the energy charge on all 1,50,000 kVAh is 15% higher, ₹1,72,125 more. The bill becomes ₹17,16,625: ₹3,07,125 more, for one spike.
What the peak hours cost
The plant above pays ₹60,000 a month for the 40,000 kVAh it uses from 6 to 10 am and 6 to 10 pm, and gets ₹35,000 back for its daytime units. Moving 10,000 kVAh a month from the peak hours into 10 am – 6 pm saves ₹20,000 a month, about ₹2.4 lakh a year.
Where Telangana plants usually save
- Never let maximum demand reach 120% of contracted demand. Above it, every unit of the month costs 15% more.
- Keep maximum demand at or below contracted demand. Every kVA above it costs ₹1,000 for the month.
- Move load out of 6–10 am and 6–10 pm into 10 am – 6 pm. Each kVAh moved saves ₹2.00.
- Keep power factor near unity. With kVAh billing, every point of power factor lost is paid for in units.
- Size contracted demand to real demand. Billing demand is never below 80% of it, so a plant that never goes above 300 kVA on a 500 kVA contract pays for 100 kVA it does not use, ₹50,000 a month.
- Check the optional category if contracted demand is up to 150 kVA at 11 kV.
How KONDUKTOR® EMS helps
KONDUKTOR® EMS reads the multifunction meters already on your panels and shows, while the month is still running, the numbers this tariff bills you on.
- Running maximum demand against contracted demand, with a warning before 100% and 120% are crossed.
- kVAh by time of day for each meter, so peak-hour units are seen the same day.
- Power factor for each meter, so a drop that inflates kVAh is caught early.
- Twelve months of maximum demand history, to size contracted demand.
Common questions
What is the industrial electricity tariff in Telangana for 2026-27?+
On TGSPDCL and TGNPDCL, HT-I(A) industry pays ₹500 per kVA of billing demand a month and ₹7.65 per kVAh at 11 kV, ₹7.15 at 33 kV and ₹6.65 at 132 kV and above, plus a customer charge of ₹2,000 to ₹5,000. LT-III industry pays ₹100 per kW of contracted load and ₹7.70 per unit. FSA, time of day and electricity duty are added.
What is the penalty for exceeding contracted demand in Telangana?+
Demand above contracted demand is billed at two times the normal demand charge, ₹1,000 per kVA on HT-I(A). Above 120% of contracted demand, the energy charge on all units of the month is also 1.15 times normal, and above 200% it is 1.20 times normal.
How is billing demand worked out on a Telangana HT bill?+
It is the higher of the maximum demand recorded in the month and 80% of contracted demand. A 500 kVA plant pays demand charges on at least 400 kVA, ₹2,00,000 a month at ₹500.
What is the ToD tariff for industry in Telangana?+
For HT-I(A) industry general, units used from 6 am to 10 am and from 6 pm to 10 pm cost ₹1.50 per kVAh more, units used from 10 am to 6 pm cost ₹0.50 less, and 10 pm to 6 am is at the normal rate, all year. LT-III industry has no time of day.
What is the minimum energy charge for HT industry in Telangana?+
HT-I(A) industry is billed for at least 50 kVAh per kVA of billing demand a month. At 470 kVA of billing demand, a month that uses fewer than 23,500 kVAh is billed for 23,500.
What is the HT-I(A) optional category?+
Industries with contracted demand up to 150 kVA at 11 kV can opt for a demand charge of ₹100 per kVA instead of ₹500, with an energy charge of ₹8.00 per kVAh instead of ₹7.65. The schedule does not list time of day for it.
Is there a power factor penalty in Telangana?+
No low power factor surcharge is levied where energy is billed in kVAh, as it is on HT. A low power factor raises the billed units instead: at 0.90, 1,35,000 kWh is billed as 1,50,000 kVAh. On LT-III, loads below 13 HP pay a 25% surcharge if their capacitors are found not working.
