IESCO Electricity Tariff Guide 2026 — Complete Rate Structure Explained
Your monthly electricity bill is calculated using a tariff structure set by NEPRA (National Electric Power Regulatory Authority). Understanding how these rates work helps you predict your bill accurately, identify which slab you fall in, and make smarter decisions about your electricity usage.
This page covers the complete 2026 tariff schedule for all IESCO consumer categories — residential, commercial, and industrial — along with a plain-language explanation of how each rate and surcharge is applied.
How the IESCO Tariff System Works
IESCO uses a slab-based tariff for residential consumers. The per-unit rate increases as monthly consumption increases — and the higher rate applies to your entire consumption, not just the extra units above the boundary.
For example: 200 units are billed at Rs. 28.91 per unit. If you consume 201 units, your entire bill shifts to Rs. 33.10 per unit — not just the one extra unit. This is why crossing a slab boundary causes a noticeable jump in your total bill.
Commercial and industrial consumers pay fixed monthly charges based on sanctioned load plus variable charges per unit, with separate peak and off-peak rates for those on Time-of-Use billing.
Residential Tariff Rates 2026
Residential consumers are split into Protected (up to 200 units monthly) and Unprotected (above 200 units). Protected consumers benefit from a government subsidy at lower rates.
| Sr No. | Consumption Slab | Rate (Rs./KWh) | Category |
| 1 | 1 – 100 Units | 22.44 | Protected |
| 2 | 101 – 200 Units | 28.91 | protected |
| 3 | 201 – 300 Units | 33.10 | Unprotected |
| 4 | 301 – 400 Units | 37.99 | Unprotected |
| 5 | 401 – 500 Units | 40.20 | Unprotected |
| 6 | 501 – 600 Units | 41.62 | Unprotected |
| 7 | 601 – 700 Units | 42.76 | Unprotected |
| 8 | Above 700 Units | 47.69 | Unprotected |
Fixed meter rent of RS. 75 per month applies to all residential connections regardless of consumption level.
Commercial Tariff Rates 2026
Commercial consumers pay based on sanctioned load. Those under 5 kW pay a flat monthly connection charge. Larger connections pay per kW of sanctioned load plus variable energy charges.
| Sr No. | CATEGORY | FIXED/Month | FIXED/kW/M | Peak Rate | Off-Peak Rate |
| 1 | For Sanctioned load up to 5 kW | Rs 1000 | – | – | Rs. 37.44 |
| 2 | For Sanctioned load above 5 kW | – | Rs. 1250 | – | Rs. 40.91 |
| 3 | – | Peak | Off-Peak | ||
| 4 | Time Of Use (TOU) | – | Rs. 1250 | Rs. 43.82 | Rs. 35.15 |
| 5 | Electric Vehicle Charging Station | – | – | Rs. 23.57 | |
| 6 | Pre-paid Commercial Supply Tariff | – | Rs. 1250 | Rs. 47.10 |
Time of Use billing is optional for commercial consumers. Peak hours run from 6 PM to 10 PM. Businesses that can shift heavy usage to off-peak hours can save Rs. 8.67 per unit.
Industrial Tariff Rates 2026
Industrial tariffs vary by sanctioned load size and voltage level. Consumers operating at higher voltages (11 kV, 33 kV, 66 kV, 132 kV) get lower per-unit rates because they manage their own transformation costs.
| Sr No. | CATEGORY | FIXED/Month | FIXED/kW/M | Peak Rate | Off-peak Rate |
| 1 | Up To 25 kW (at 400/230 Volts) | Rs. 1000 | – | – | Rs. 30.80 |
| 2 | 25-500 kW (at 400 Volts) | – | Rs. 1250 | – | Rs. 30.73 |
| 3 | – | – | Peak | Off-Peak | |
| 4 | TOU — Up to 25 kW | Rs. 1000 | Rs. 1250 | Rs. 36.74 | Rs. 30.05 |
| 5 | TOU — 25-500 kW (at 400 Volts) | – | Rs. 1250 | Rs. 36.68 | Rs. 27.41 |
| 6 | All Loads up to 5000 kW (at 11 or 33 kV) | – | Rs. 1250 | Rs. 36.68 | Rs. 28.24 |
| 7 | All Loads (at 66 or 132 kV & above) | – | Rs. 1250 | Rs. 36.68 | Rs. 27.96 |
| 8 | Pre-paid Industrial | Rs. 1250 | Rs. 44.46 |
Surcharges and Adjustments Explained
Beyond the base tariff, your bill includes government-mandated surcharges set by NEPRA. These apply uniformly across all distribution companies in Pakistan, including IESCO.
| Charge Name | What It Means | How It Appears on the Bill |
| FPA — Fuel Price Adjustment | Monthly adjustment for change in fuel cost used to generate electricity. Can be positive (bill increases) or negative (bill decreases). | Shown as + or – Rs. per unit consumed |
| TR Surcharge | Tariff Rationalisation Surcharge — added to align electricity prices gradually with actual production costs. | Fixed per-unit amount added to energy charges |
| FC Surcharge | Financing Cost Surcharge — covers interest costs that distribution companies incur on dues owed to power producers. | Fixed per-unit amount on bill |
| QTR Adjustment | Quarterly Tariff Adjustment — a correction every three months when actual costs differ from annual tariff assumptions. | Fixed per-unit amount on the bill |
| GST 17% | General Sales Tax on total electricity charges including all surcharges above. | Percentage of total taxable amount |
| TV Fee | Government fee for PTV collected through electricity bills. | Flat Rs. 35 per month for all consumers |
Key insight: FPA is the main reason your bill changes month to month, even with identical consumption. NEPRA revises the FPA every month based on fuel prices. A high FPA month can add Rs. 500 to Rs. 2000 to your total bill with zero change in usage.
Peak and Off-Peak Hours — Time of Use Billing
Time of Use billing is available to commercial and industrial consumers who want to reduce costs by shifting electricity usage to off-peak hours.
Peak Hours — 6 PM to 10 PM
- Highest demand period — grid load is maximum across Pakistan during these hours.
- Commercial TOU consumers pay Rs. 43.82 per kWh during peak hours.
- Industrial TOU consumers pay Rs. 36.68 to Rs. 36.74 per kWh, depending on load.
Off-Peak Hours — All Other Times
- Applies during nighttime, early morning, and daytime hours outside 6 to 10 PM
- Commercial off-peak rate: Rs. 35.15 per kWh — a saving of Rs. 8.67 per unit vs peak
- Industrial off-peak rates range from Rs. 27.41 to Rs. 30.05 per kWh based on load size
TOU billing is most beneficial for factories, cold storage facilities, and businesses that can schedule heavy machinery or cooling operations during nighttime hours.
How to Identify Your Tariff Category on Your IESCO Bill
Your printed IESCO bill shows exactly which tariff applies to your account. Here is where to find this information:
- Consumer category code — Look for codes like A-1 (residential protected), A-2 (residential unprotected), B (commercial), or C (industrial) on the top section of your bill
- Rate per unit — Your bill shows the exact Rs. per kWh rate applied to your consumption this month
- Slab applied — The bill confirms which consumption slab was used. If it shows 201 to 300 units slab, your entire consumption was charged at Rs. 33.10 per kWh
- Surcharge lines — Each surcharge appears as a separate line item. Compare these to last month to see if FPA or TR increased — this explains higher bills with the same unit consumption
