Odisha industrial electricity tariff: HT and LT supply.

Who this page covers

Odisha has four distribution companies on one tariff, set by the Odisha Electricity Regulatory Commission (OERC): TPCODL, TPNODL, TPWODL and TPSODL. OERC’s common order of 24 March 2026 applies from 1 April 2026 until further order.

• HT and EHT supply: Large Industry, Power Intensive Industry, Mini Steel Plants and General Purpose from 110 kVA, on one rate, and HT Industrial (M) Supply at a lower demand rate.
• LT supply: LT Industrial (S) below 22 kVA, LT Industrial (M) from 22 to below 110 kVA, and Large Industry at LT from 110 kVA.

HT and EHT rates

Energy is graded by load factor and billed in kVAh. Units up to the 60% load factor point are billed at the first rate, and only units beyond it at the second.

For supply of 100 kW and above, load factor is units ÷ (maximum demand × hours), so the power factor cancels: it is kVAh ÷ (kVA × hours). Hours are the billing period less allowable interruption hours. OERC sets 60 hours a month as the limit and makes no deduction at 60 hours or less, so check how your bill counts them. A plant at 470 kVA over 720 hours reaches the 60% point at 2,03,040 kVAh.

LT rates

Below 110 kVA, the recorded demand, rounded to the nearest 0.5 kW, counts as your contract demand and sets the fixed charge, and the charge follows the highest demand recorded in the financial year.

Billing demand and overdrawal

The demand charge is on the recorded maximum demand or 80% of contract demand, whichever is higher. A new provision for three-part tariff above 110 kVA took effect on 1 July 2026, after each meter is configured for it, and it separates demand by time of day:

So what matters most is keeping demand within contract demand from 6 pm to midnight. Until your meter is configured for the rule, your bill follows the general rule: recorded maximum demand or 80% of contract demand. Check which one your bill uses.

kVAh billing and power factor

HT and EHT energy is in kVAh, so a low power factor raises the units themselves. A plant that uses 1,35,000 kWh at 0.90 is billed for 1,50,000 kVAh; at 0.98 it would be about 1,37,755 kVAh, about ₹72,000 less a month at ₹5.85. LT supply is billed in kWh. The kVAh billing guide explains the difference.

Time of day from 1 July 2026

Time of day applies from 1 July 2026 to smart and AMR meters with contract demand above 10 kW, except irrigation, pumping and agriculture.

Rebates and other lines

• HT Large Industry and similar: 1% of the monthly bill, excluding arrears, if paid within 3 working days of presentation.
• LT Industrial (S): 10 paise a unit on energy if paid by the due date. LT Industrial (S) and (M): a further 10 paise a unit if monthly load factor is above 30% and paid by the due date.
• Prepaid: 4% on the prepaid amount. E-bill: ₹10.
• Steel plants without a captive generating plant, contract demand 1 MVA and above: a load factor rebate on total energy of 10% from 65% to 75% (only up to 6 MVA), 15% from 75% to 85% (8% above 6 MVA), and 20% above 85% (10% above 6 MVA).
• EHT industrial: 30 paise per kVAh rebate on units beyond 80% load factor.
• 33 kV without a captive plant, up to 10 MVA: by agreement, you can draw up to double contract demand with no penalty at a minimum 80% load factor, with ₹5.00 per kVAh beyond 80% of contract demand.
• Meter rent: ₹1,000 a month at 11 kV and ₹2,000 at 33 kV, for 60 months.

Worked example: a 500 kVA plant at 11 kV

An illustrative HT Large Industry plant with contract demand 500 kVA. Its highest demand is 470 kVA in Peak hours and outside them, and it uses 1,50,000 kVAh over 720 hours: 75,000 in Solar hours and 30,000 in Peak hours.

Illustrative figures from the OERC order. Your DISCOM may round in its own way. Work out your own with the electricity bill calculator.

Double the units and the plant passes the 60% point. At 3,00,000 kVAh on the same 470 kVA, with the same share in Solar and Peak hours, the bill is ₹17,16,644: about ₹5.72 per kVAh, against ₹6.46.

What one demand spike costs

Under the 1 July rule, when the spike happens decides the cost. Say this plant reaches 560 kVA in one short spike.

• Outside Peak hours: 112% of contract demand is within 120%, and Peak-hour demand stayed within contract demand. No charge on it. The bill stays ₹9,68,925.
• In Peak hours, 6 pm to midnight: the 120% allowance is gone. The demand charge moves to 560 kVA, and ₹250 per kVA applies to the 60 kVA above contract demand. Those 60 kVA cost ₹30,000, and the bill goes to ₹10,06,425, ₹37,500 more.
• At 620 kVA outside Peak hours: ₹250 on the 20 kVA above 120%, ₹5,000.

Where Odisha plants usually save

• Move heavy load out of 6 pm to midnight. Peak-hour demand within contract demand is what keeps the 120% allowance, and Peak units cost 10% more.
• Run more in Solar hours. From 8 am to 4 pm each kVAh is 10% cheaper.
• Raise load factor past 60%. Every kVAh above that point drops from ₹5.85 to ₹4.75 at HT.
• Keep power factor near unity. With kVAh billing, every point lost is paid for in units.
• Size contract demand to real demand. The floor is 80%. At 350 kVA of real demand on a 500 kVA contract you pay for 400, so the unused 50 kVA costs ₹12,500 a month.

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.

• Maximum demand kept apart for Peak hours and other hours, against contract demand.
• Running load factor, so you see how close you are to the 60% point.
• kVAh in Solar, Peak and Normal hours, for each meter.
• Power factor for each meter, so a drop that inflates kVAh is caught the same day.
