State tariff guide
Delhi industrial electricity tariff: ₹250 per kVA, ₹7.75 per kVAh.
Every line on a Delhi factory bill, from the DERC tariff schedule that BSES, Tata Power-DDL and NDMC still bill on. Then a worked bill for a 400 kVA plant at 11 kV, and what one demand spike adds to it.
Who this page covers
Delhi has four distribution licensees on one tariff, set by the Delhi Electricity Regulatory Commission (DERC): BSES Rajdhani (BRPL) in south and west Delhi, BSES Yamuna (BYPL) in east and central Delhi, Tata Power Delhi Distribution (TPDDL) in north and north-west Delhi, and the New Delhi Municipal Council (NDMC).
- Industrial: industries and hospitals, with their lighting, heating and cooling load. It is one category for LT and HT; HT supply gets a rebate on energy.
- A valid factory licence is required. It can be from the Directorate of Industries, the MSME ministry, MCD or another government agency. Without it, or while a renewal is pending, the connection is billed as non-domestic, at ₹8.50 per kVAh instead of ₹7.75. The bills are adjusted from the date the licence is renewed.
The rates were set in DERC’s tariff schedule for FY 2020-21 and are still the ones billed. DERC has issued true-up orders since then, which say they do not change the current tariffs. As of 3 November 2026, no newer Delhi tariff order has been issued that we have found.
Industrial rates
| Charge | Industrial, LT and HT |
|---|---|
| Fixed charge | ₹250 per kVA of billing demand a month |
| Energy charge | ₹7.75 per kVAh |
| HT rebate on the energy charge | 3% at 11 kV, 4% at 33 / 66 kV, 5% at 220 kV |
Energy is billed in kVAh, so there is no separate power factor penalty or incentive: a low power factor shows up as more kVAh on the meter. Where the sanctioned load is in kW, it is turned into kVA at the month’s actual power factor. The kVAh billing guide explains how.
Billing demand and the 30% surcharge
- Maximum demand is the highest average load over 30 consecutive minutes in the billing cycle.
- Billing demand is the higher of the sanctioned load (or contract demand) and the maximum demand. A 400 kVA connection pays for 400 kVA even in a month it uses 300.
- Above the sanctioned load, the fixed charge on the excess kVA carries a 30% surcharge, for that billing cycle only.
The yearly load review
Every year the DISCOM looks at the previous April to March and takes the highest average of maximum demand over any four consecutive months, rounded down. If that is above the sanctioned load, it sends a notice to raise the load, with a higher security deposit. If you ask to reduce the load, it can only come down to that same four-month average.
So one spike costs you a month’s surcharge, but demand that stays high for four months in a row raises the fixed charge for every month after. The contract demand guide shows how to size the load.
ToD hours: May to September only
Time-of-day billing applies to every non-domestic connection whose sanctioned load or maximum demand, whichever is higher, is 11 kVA or more. It runs only from May to September, and changes the energy charge only.
| Hours, May to September | Energy charge |
|---|---|
| 2 – 5 pm and 10 pm – 1 am (peak) | +20% |
| 4 – 10 am (off-peak) | −20% |
| All other hours | Normal |
From October to April every unit pays the normal rate. A unit moved from the peak to the off-peak hours in summer saves 40% of the energy rate: ₹3.10 at ₹7.75, before the surcharges. The TOD tariff guide covers which loads can move.
Surcharges on top of the tariff
- 8% deficit surcharge, towards the DISCOMs’ accumulated deficit.
- Pension trust surcharge, for the pensions of former Delhi Vidyut Board staff. It was 5% in the FY 2020-21 schedule and has been 7% since 1 October 2021.
Both are charged on the fixed and energy charges only, not on PPAC, the 30% load surcharge, electricity tax or arrears. They apply to BRPL, BYPL and TPDDL consumers, not to NDMC.
- PPAC and FPPAS (power purchase cost adjustment) is a percentage that changes every month and differs by DISCOM. It is applied after the ToD surcharge and rebate. As an example, BRPL levies FPPAS at 10% on bills for October 2026; it was 17.94% in May and June 2026 and 12.38% in July. Take the current figure from your bill.
Electricity tax is levied on top by the municipal body; take its rate from your latest bill. A late payment surcharge of 18% a year is charged for each day after the due date. Prepaid meters get a further 1% rebate on the whole bill.
Worked example: a 400 kVA plant at 11 kV
An illustrative BSES or Tata Power-DDL industrial plant at 11 kV with a sanctioned load of 400 kVA, in a summer month. Its maximum demand is 380 kVA and it uses 1,50,000 kVAh: 30,000 in the peak hours and 45,000 in the off-peak hours. PPAC and FPPAS are 10%.
| Bill line | Working | Amount |
|---|---|---|
| Billing demand | Higher of 400 kVA sanctioned and 380 kVA | 400 kVA |
| Fixed charge | 400 kVA × ₹250 | ₹1,00,000 |
| Energy charge | 1,50,000 kVAh × ₹7.75 | ₹11,62,500 |
| Peak-hour surcharge | 30,000 kVAh × ₹7.75 × 20% | ₹46,500 |
| Off-peak rebate | 45,000 kVAh × ₹7.75 × 20% | −₹69,750 |
| 11 kV rebate | 3% of ₹11,39,250 | −₹34,178 |
| PPAC and FPPAS | 10% of ₹12,05,072 | ₹1,20,507 |
| Deficit surcharge | 8% of ₹12,05,072 | ₹96,406 |
| Pension trust surcharge | 7% of ₹12,05,072 | ₹84,355 |
| Before electricity tax | About ₹10.04 per kVAh | ₹15,06,340 |

The 20 kVA of sanctioned load it did not use still costs ₹6,250 this month with the surcharges. The same plant in an October to April month, with no ToD, pays ₹15,34,532: the off-peak rebate it loses is larger than the peak surcharge it saves.
What one demand spike costs
Suppose the same plant has one bad half-hour, say several heavy motors restarting together after a power cut, and maximum demand reaches 500 kVA. Billing demand becomes 500 kVA: the fixed charge goes to ₹1,25,000, the 100 kVA above the sanctioned load adds ₹7,500 of 30% surcharge, and PPAC and the two surcharges rise with the fixed charge. The bill goes from ₹15,06,340 to ₹15,45,090: ₹38,750 more, for one half-hour. If demand like that holds for four months in a row, the sanctioned load is raised at the yearly review. The MD penalty guide explains how to stop it.
Where Delhi plants usually save
- Keep power factor near 1. On kVAh billing, raising it from 0.96 to 0.99 on the same work cuts this plant’s bill to ₹14,64,486: ₹41,854 a month.
- Move flexible load from the summer peaks to 4 – 10 am. Moving 10,000 kVAh saves ₹37,588 a month on this plant.
- Keep maximum demand within the sanctioned load, and below it for four months running, so the yearly review does not raise it.
- Size the sanctioned load to real demand. Every unused kVA costs about ₹312 a month with the surcharges.
- Keep the factory licence valid. A lapsed licence moves the bill to ₹8.50 per kVAh.
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 the sanctioned load, with a warning before it crosses.
- Power factor for each meter, so the extra kVAh is caught the same day.
- Hourly energy, so you can see how much falls in the summer peak and off-peak hours.
- Twelve months of maximum demand history, with the four-month averages the yearly review uses.
Common questions
What is the industrial electricity tariff in Delhi?+
Industries and hospitals in Delhi pay a fixed charge of ₹250 per kVA of billing demand a month and an energy charge of ₹7.75 per kVAh, the same for LT and HT. HT supply gets a rebate of 3% on the energy charge at 11 kV, 4% at 33 or 66 kV and 5% at 220 kV. The rates are from DERC’s tariff schedule for BRPL, BYPL, Tata Power-DDL and NDMC. ToD in summer, an 8% surcharge, a 7% pension trust surcharge, PPAC and electricity tax are added on top.
What are the ToD hours in Delhi?+
From May to September, energy used from 2 to 5 pm and from 10 pm to 1 am costs 20% more, and energy used from 4 to 10 am costs 20% less. Other hours, and every hour from October to April, pay the normal rate. ToD applies to every non-domestic connection with a sanctioned load or maximum demand of 11 kVA or more, and changes the energy charge only.
What is billing demand in Delhi?+
The higher of the sanctioned load (or contract demand) and the maximum demand recorded in the billing cycle, where maximum demand is the highest average load over 30 minutes. So a Delhi connection always pays the fixed charge on its full sanctioned load, even in a month it uses less.
What is the penalty for exceeding sanctioned load in Delhi?+
The fixed charge on the kVA above the sanctioned load carries a 30% surcharge, for that billing cycle only. At ₹250 per kVA, 100 kVA over the load adds ₹25,000 of fixed charge and ₹7,500 of surcharge. If the average maximum demand of any four consecutive months in a financial year is above the sanctioned load, the DISCOM raises the load at its yearly review.
What is the pension trust surcharge on a Delhi electricity bill?+
A surcharge for the pensions of former Delhi Vidyut Board staff, charged on the fixed and energy charges of BRPL, BYPL and Tata Power-DDL consumers. It was 5% in the FY 2020-21 tariff schedule and has been 7% since 1 October 2021. An 8% surcharge towards the DISCOMs’ accumulated deficit is charged on the same base. Neither applies to NDMC.
What is PPAC or FPPAS on a Delhi bill?+
The power purchase cost adjustment, a percentage added each month for the change in the DISCOM’s power purchase cost. It differs by DISCOM and changes every month; for example BRPL levies FPPAS at 10% on October 2026 bills, after 17.94% in May and June 2026 and 12.38% in July. Take the current figure from your bill.
Is there a power factor penalty in Delhi?+
No separate one. Delhi bills energy in kVAh, and a low power factor shows up as more kVAh for the same work. On a 400 kVA plant using 1,50,000 kVAh at 0.96 power factor, raising it to 0.99 saves about ₹42,000 a month.
