'E' BillPrint this page 

The 'E' (Estimated) Bill is a bill that is based on an estimate of your consumption of electricity in a month.  You will know that your bill is an Estimated Bill when there is the letter 'E' printed in the Meter Reading Code section on your bill. 

This bill is issued in the event that TNB meter readers are unable to read the meter in your premises.  Some common reasons why our meter readers are unable to perform the meter reading:

  • The gates or front door to your premises are locked, preventing access to your meter;
  • A large object has been placed in front of the meter, blocking it from the meter reader's view.
  • You have guard pets preventing our meter readers from safely performing meter reading on your premises;
  • Natural disasters such as floods preventing access to the road or bridge leading to your home

If the monthly electricity consumption stated in the E bill is 91 units or less, you will still be entitled for the RM20 Government subsidy.

Please be informed that implementation of the E bill is not detrimental to you, nor it is beneficial to TNB. This is because  we will make a manual adjustment of your electricity bill when an actual (N) reading is submitted the following month.


How the E Bill is determined

The total usage stated on the E bill is derived from your average consumption, calculated automatically by our billing system based on your monthly electricity usage for the last six months. Your monthly electricity usage is based on actual meter readings performed on your premises.  Your average consumption is then multiplied by the billing period and the applicable tariff rates to determine the total bill amount.

Your average consumption will be continuously calculated and updated in the billing system whenever actual (N)readings are made. This means that your average usage will NOT include estimated (E) readings or average (A) readings (due to faulty meter).

How the E Bill is calculated

Scenario 1: Average consumption based on meter readings conducted every month

Based on the given example, your estimated consumption will be calculated as follows:

Total monthly consumption = Average consumption x Billing Period (days) 
  = 638.29/30 x 30
  = 638.29 units
  = 638 units (after rounding)

For residential premises, based on current tariff rates, the E Bill amount will be:

First 500 units = 500 x RM0.286  = RM143.00
Next 100 units = 100 x RM0.378  = RM37.80
Next 38 units = 38 x RM0.387  = RM14.71
E Bill Amount = RM195.50 (after rounding)

Scenario 2: Average consumption based on a combination of monthly readings (N) and estimated readings (E)

Based on the given example, suppose your average consumption is 400 units or less.  Your estimated consumption will be calculated as follows:

Total monthly consumption = Average consumption x Billing Period (days) 
  = 397.96 / 30 x 30
  = 397.96 units
  = 398 units (after rounding)

For residential premises, based on current tariff rates, the E Bill amount will be:

First 200 units = 200 x RM0.218  = RM43.60
Next 198 units = 198 x RM0.334  = RM66.13
E Bill Amount = RM109.75 (after rounding)

How bill adjustments are made 

Once an actual (N) reading has been obtained, a adjustment will be made on your bill.

Suppose the actual (N) reading of your consumption for two (2) months is 1,280 units.  Your bill amount for that period will be:

First 1,000 units = 1,000 x RM0.286 = RM286.00
Next 200 units = 200 x RM0.378 = RM75.60
Next 80 units = 80 x RM0.387   = RM30.96
Total bill amount = RM392.56

As per scenario 1 above, suppose the payment received for your previous E Bill was RM195.50:

Total bill amount (after adjustment) = RM392.56 - RM195.50
  = 197.05 (after rounding)

As you can see, once an actual (N) bill is issued to you, the amount you have paid previously for your E Bill will be subtracted from your existing bill amount.  You will not suffer losses in any way.
