units

The bill shows the FPA month, e.g. "FPA for JUL-26". Enter your units for that month from the 12-month history. Leave blank to use this month's units.

Quarterly adjustment billed September to November 2026. It can be negative, e.g. -0.45. Use the figure on your bill if it differs.

Ticked because many recent bills still show it. Untick it if your bill has no electricity duty line.

Non-filers pay 7.5% income tax when the bill is Rs 25,000 or more.

Bills round the current bill to the nearest rupee and put the few paisa of difference in the cost of electricity line. The late payment surcharge is on the electricity charges without the fuel adjustment and taxes; your bill prints the last date for the lower amount. The first bill of a new connection can cover more than one month.

Enter your TESCO units and pick your consumer type. With the current adjustments, 100 units on a 1 kW connection costs about Rs 927 on the lifeline tariff, Rs 1,895 if protected and Rs 3,739 if unprotected.

TESCO is the Tribal Electric Supply Company, serving the merged tribal districts of Khyber Pakhtunkhwa. It bills homes on the same national uniform tariff as every other company.

Three bills for the same 100 units

At low use, your consumer type decides almost everything.

Consumer type Rate Fixed charge (1 kW) Estimated bill
Lifeline Rs 7.74 on all 100 units none Rs 926.61
Protected Rs 10.54 Rs 200 Rs 1,894.81
Unprotected Rs 22.44 Rs 275 Rs 3,738.66

Lifeline homes also skip the fuel adjustment and the quarterly adjustment. They do not pay the FC surcharge either. Protected homes pay it at Rs 0.43 a unit and unprotected homes at Rs 3.23.

Worked example: 100 units, protected, 1 kW

Line Working Amount
Cost of electricity 100 × 10.54 Rs 1,054.00
Fixed charges 1.0 kW × Rs 200 Rs 200.00
FC surcharge 100 × 0.43 Rs 43.00
Quarterly adjustment 100 × 0.5194 Rs 51.94
Fuel adjustment 100 × 2.3673 Rs 236.73
Electricity charges Rs 1,585.67
Electricity duty 1.5% of cost of electricity and QTA Rs 16.59
GST 18% of the charges above and duty, rounded Rs 246.00
Duty on fuel adjustment 1.5% of the fuel adjustment Rs 3.55
GST on fuel adjustment 18% of the fuel adjustment and its duty, rounded Rs 43.00
Government charges Rs 309.14
Total Rs 1,894.81

Pay after the due date and a late payment surcharge is added: 5% of Rs 1,349.13 (the electricity charges without the fuel adjustment and taxes) for the first 3 days, so Rs 1,962, then 10%, so Rs 2,030.

Who qualifies for lifeline and protected

  • Lifeline: single-phase connection, sanctioned load up to 1 kW, and no more than 100 units a month. Lifeline users get no slab benefit: 80 units are billed at Rs 7.74 each, not at Rs 3.95 for the first 50.
  • Protected: 200 units or less in each of the last six months.
  • Unprotected: everyone else.

If a lifeline home uses more than 100 units, the calculator moves it to unprotected rates.

Electricity duty and reading your bill

The merged districts are part of Khyber Pakhtunkhwa. Electricity duty does not appear on every TESCO home bill, so match the duty box to your bill.

You need the units consumed and the sanctioned load in kW from your bill. If your bill is based on an estimated reading rather than a meter reading, the calculator can still show what those units should cost.

TESCO's neighbours bill on the same national tariff: the PESCO bill calculator and the HAZECO bill calculator.

Protected TESCO bill by units

Questions people ask

What is the lifeline electricity rate in 2026?

Rs 3.95 per unit for up to 50 units, and Rs 7.74 per unit for 51 to 100 units, under the February 2026 NEPRA tariff. All units are charged at the rate of the slab you land in. There is no fixed charge and no fuel or quarterly adjustment.

How much is a 100 unit TESCO bill?

About Rs 927 on the lifeline tariff, Rs 1,895 if protected and Rs 3,739 if unprotected, on a 1 kW connection with the current adjustments with duty included. The electricity bill calculator compares 100 unit bills in more detail.

Is the TESCO tariff different from PESCO?

No. TESCO, PESCO, HAZECO and the other companies all charge the same national uniform tariff notified in February 2026. The fuel and quarterly adjustments are set in the same NEPRA decisions for all of them.

Do lifeline users pay GST?

Yes. GST at 18% is charged on the cost of electricity and any duty, even on a lifeline bill. For 100 lifeline units that is about Rs 141.
