Pakistan electricity sector, plain-language guide

When your monthly bill arrives, it reflects decisions made by at least five different organisations before electricity reaches your socket. This guide explains who each one is, what they control, and why it matters for your bill amount.

1. How electricity moves from plant to meter

Pakistan's power supply chain has three stages:

Generation: Power plants produce electricity. Pakistan's mix includes hydropower (major dams like Tarbela and Mangla), thermal plants running on furnace oil, coal, gas, and LNG, plus growing wind (Jhimpir corridor) and solar (Quaid-e-Azam Solar Park). Nuclear plants (Chashma, KANUPP) contribute a smaller but stable share. The fuel cost to run thermal plants is the biggest driver of your monthly bill swings.
Transmission — The National Transmission and Despatch Company (NTDC) carries high-voltage electricity across long distances from plants to cities. NTDC is a separate entity from your DISCO and is not involved in billing.
Distribution, Distribution companies (DISCOs)receive power from NTDC's grid, reduce it to usable voltages, and deliver it to homes, shops, farms, and factories. Your DISCO is who bills you and who you call for outages.

2. WAPDA, what it actually is today

Most Pakistanis call their electricity bill a "WAPDA bill" out of habit. The Water and Power Development Authority (WAPDA)was originally responsible for electricity distribution countrywide. In the 1990s and 2000s, government reforms split that function: distribution companies (DISCOs) were created as separate entities and billing moved to them. Today WAPDA's role is primarily hydro generation(it operates the major dams) and water infrastructure. Your bill comes from your DISCO, MEPCO, LESCO, FESCO, etc. — not from WAPDA itself. There is no single "WAPDA bill counter" for residential consumers.

3. NEPRA, the regulator behind your tariff

The National Electric Power Regulatory Authority (NEPRA) is an independent regulator that sets the rules DISCOs must follow. When your bill changes even though your units stayed the same, it is almost always because NEPRA approved or reversed an adjustment. Key things NEPRA controls:

Base tariff slabs: The per-unit (kWh) rates for domestic, commercial, industrial, and agricultural consumers. Domestic residential rates are tiered: as monthly consumption rises, the marginal rate per unit climbs in steps (0–50, 51–100, 101–200, 201–300, 301–500, 501–700, 700+ units). Crossing into a higher slab applies the higher rate to every unit above that threshold.
Fuel Price Adjustment (FPA). A monthly variable charge that reflects actual generation fuel costs (furnace oil, LNG, coal) vs the reference cost built into the base tariff. When fuel prices rise or the rupee weakens, FPA is positive (a surcharge). When hydro output is high or fuel prices drop, FPA can be negative (a credit). It is the main reason identical consumption produces different bill totals each month.
Tariff Rationalization Surcharge (TRS) — A fixed surcharge to help balance the uniform national tariff across regions with different generation costs.
Protected consumer categories: Residential consumers using 200 units or fewer per month for six consecutive months qualify as "protected" and pay subsidized slab rates. Using more than 200 units in any one month resets the clock for six months.

NEPRA publishes all tariff determinations at nepra.org.pk. If your total jumped significantly, check the current FPA figure there first.

4. Pakistan's 11 DISCOs

Each distribution company holds a NEPRA licence for a defined geographic territory. Your DISCO is determined by your physical location. You cannot choose between them. The 11 are:

LESCO: Lahore, Sheikhupura, Kasur, Okara, Nankana Sahib
GEPCO — Gujranwala, Sialkot, Gujrat, Hafizabad, Narowal, Mandi Bahauddin
FESCO: Faisalabad, Sargodha, Jhang, Toba Tek Singh, Chiniot, Khushab, Bhakkar
IESCO: Islamabad, Rawalpindi, Attock, Chakwal, Jhelum
MEPCO: Multan, Bahawalpur, DG Khan, Rahim Yar Khan, Sahiwal, Vehari, Lodhran, Khanewal, Muzaffargarh, Bahawalnagar
PESCO — Peshawar, Mardan, Swat, Dir, Kohat, Bannu, Dera Ismail Khan, Nowshera
HAZECO: Abbottabad, Mansehra, Haripur, Battagram, Kohistan
HESCO: Hyderabad, Badin, Mirpurkhas, Nawabshah, Sanghar, Thatta
SEPCO: Sukkur, Larkana, Khairpur, Shikarpur, Jacobabad, Dadu
QESCO — Quetta, Gwadar, Sibi, Khuzdar, Chaman, Loralai, Zhob
TESCO: Merged tribal districts (former FATA: Khyber, Kurram, Waziristan, Bajaur, Mohmand, Orakzai)

K-Electric (Karachi) is not one of these 11. It is a private, vertically integrated utility serving Karachi and surrounding areas on its own billing system at ke.com.pk. It is not on the PITC portal and cannot be checked on CheckBills.pk.

5. PITC, the billing platform behind your duplicate bill

The Power Information Technology Company (PITC) is a government body that operates the shared billing portal at bill.pitc.com.pk. All 11 DISCOs use PITC to generate and deliver duplicate bills. When you enter your reference number on CheckBills.pk, your request is forwarded to the PITC system, you receive the same official document that your DISCO's customer-service counter would show you. No data is added or removed. PITC also runs the Electronic New Connection (ENC) service at enc.pitc.com.pk and the Cross Subsidy Scheme (CSS) registration at css.pitc.com.pk.

6. What appears on your bill — line by line

Reference / Consumer Number, 10–14 digits identifying your meter connection. Required for all online lookups.
Billing month: The cycle period; the bill typically arrives 1–2 weeks after the reading date.
Units consumed: Kilowatt-hours used. This drives your slab tier.
Energy charge — Units × the applicable slab rate(s). If you cross slab boundaries, each band is charged at its own rate.
Fuel Price Adjustment (FPA). The monthly NEPRA-approved per-unit surcharge or credit based on actual fuel costs.
Financing Cost Surcharge: A fixed levy for debt servicing on power-sector borrowing.
GST: General Sales Tax, a percentage of your energy charge.
TV fee — A flat PKR 35/month levy for PTV (Pakistan Television Corporation), collected via electricity bills.
Meter rent: A small monthly charge for the physical meter, where applicable.
Arrears: Any unpaid balance from a previous cycle carried forward.
Amount due / Amount after due date: Two totals: pay by the due date to avoid LPS (Late Payment Surcharge).

7. Consumer categories that affect your rate

Domestic protected— Residential consumers with ≤200 units/month for all 6 previous months. Pay the subsidized lower slab rates. Status shown on bill as "A-1(01)-Protected".
Domestic unprotected: Residential consumers exceeding 200 units in any recent month. Pay the full (higher) slab rates for the next 6 months.
Lifeline: Residential consumers consistently using ≤50 units/month. Exempt from FPA and pay the lowest possible rate. Rare in practice.
Commercial / Industrial / Agricultural: Different base rates and fixed charges apply. Agricultural consumers often have specific tariff codes for tube-well pumps.
