Common Misconceptions About WAPDA and IESCO
When it comes to electricity in Pakistan, there’s often confusion between WAPDA and IESCO. Many people mix up their roles, which leads to misunderstandings about who does what. Let’s clear the air once and for all.
Does WAPDA send electricity bills? – Not True!
One of the biggest misconceptions is that WAPDA issues electricity bills. In reality, WAPDA doesn’t deal directly with consumers at all. Its primary role is in power generation (mainly through hydropower dams) and water management projects.
The electricity bills you receive at home come from distribution companies (DISCOs)—and if you live in Islamabad, Rawalpindi, or surrounding districts, that company is IESCO (Islamabad Electric Supply Company).
WAPDA Builds Dams, IESCO Delivers Power
Another common mix-up is thinking that IESCO builds dams like Tarbela or Mangla. That’s completely WAPDA’s domain. IESCO’s job starts after electricity is generated—it distributes electricity to homes, businesses, and industries, manages billing systems, and handles customer complaints or new connections.
So, while WAPDA focuses on national-level energy and water projects, IESCO operates regionally to ensure you get electricity at your doorstep.
