Complete Guide to Iesco Slab Rates (IESCO)
What Are IESCO Slab Rates?
IESCO slab rates are tiered electricity charges based on how many units you consume in a month. As your consumption increases, your tariff rate rises. This system encourages consumers to save energy and avoid entering higher slabs.
Why Slab Rates Matter
Understanding slab rates matters because even a slight increase in units can shift you into a costlier category. With correct knowledge, you can track your usage and stay in a cheaper slab.
How IESCO Calculates Your Bill
Understanding Unit-Based Billing
IESCO calculates the bill using monthly meter readings. Units are divided into slabs, and each slab has a fixed rate. Your bill reflects charges from all slabs up to your consumption level.
Key Components of Your Electricity Bill
Your electricity bill includes more than unit charges. It also includes:
- Fuel price adjustments
- Government taxes
- TV license fees (for some users)
- Additional charges for high energy usage
Each component affects your total payable amount.
IESCO Domestic Slab Structure
Monthly Unit Slabs
Domestic consumers fall into these general slabs:
1–50 Units
This slab has the lowest tariff and supports low-income households.
51–100 Units
Slightly higher than the first slab but still affordable.
101–200 Units
Many households fall into this category.
201–300 Units
Crossing this slab greatly increases the bill.
301–700 Units
Higher consumption leads to noticeably higher costs.
Above 700 Units
This slab has the highest tariff.
How Slab Shifting Affects Your Bill
Crossing Slabs Increases Cost
Even if you cross by one unit, you may fall into a more expensive slab.
Incremental Slabs
IESCO uses incremental billing, meaning you pay different rates for different unit blocks, not a flat rate for all units.
Impact of Seasonal Consumption
Summer usually increases consumption due to cooling appliances. Online Bill Check Understanding slab changes can help you plan usage during high-demand months.
Practical Example of IESCO Slab Billing
How a 250-Unit Consumer Is Charged
A consumer using 250 units will be charged:
- First 100 units at lower rates
- Next 100 at a slightly higher rate
- Remaining 50 units at an even higher rate
This calculation demonstrates how slab-based billing works in layers.
Common Mistakes by Consumers
- Assuming all units are charged at the current slab
- Ignoring seasonal usage patterns
- Not monitoring daily consumption
