'A' BillPrint this page 

The 'A' Bill is also known as the average bill.  It is based on an estimate of your average electricity consumption in one month.  You will know that your bill is an A Bill when there is the letter 'A' printed in the Meter Reading Code section on your bill.

An A bill will be issued to you in the event that a TNB meter reader finds that your meter is not functioning or faulty. 

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

Backdated Billing and Billing Adjustments

If the cause of the faulty meter was due to normal irregularities, backdated billing will be done no more than 3 months from the date you are informed about the faulty meter.
 
Backdated billing will be done based on your average power consumption.  This average is calculated based on your actual consumption over the three (3) months after your faulty meter has been replaced. 

Billing adjustments are done by taking your backdated bill amount and subtracting it with the amount you have paid during the time your meter is faulty.  If it is found that you have paid more than you should, then the difference will be credited back to your account.  However if it is found you have not paid enough, you will have to settle the outstanding amount.

How Your Average Consumption is Determined

The A Bill calculation is based on your average electricity usage for the past 6 months, based on actual meter reading at your premises.  The average usage is then multiplied by the duration being billed and the tariff rate to determine the bill amount.

Average electricity usage will be updated in the billing system once actual reading is conducted. This means that average amounts will not be updated in the billing system in cases of estimate bills or average bills due to faulty meters.

Here are 2 methods to determine your average consumption, based on meter reading scenarios at your premises:

Scenario 1: Meter Readings conducted every month

Reading Date No. of Days Meter Reading Code Meter Reading Usage (kWh)
19.12.2008 30 N 97,432 601.00
19.01.2009 31 N 98,074 642.00
18.02.2009 30 N 98,677 603.00
19.03.2009 30 N 99,318 641.00
19.04.2009 31 N 99,956 638.00
18.05.2009 29 N 100,682 726.00
Total 181     3,851.00
 
Total no. of days = 30 + 31 + 30 + 30 + 31 + 29
                         = 181 days
 
Total usage         = 601 + 642 + 603 + 641 + 638 + 726
                         = 3,851.00 Units
 
Average usage    = 3,851/181 x 30 days
                         = 638.29 Units

Scenario 2: Combination of monthly readings and estimated billing

Reading Date No. of Days Meter Type Meter Reading Usage (kWh)
19.12.2008 30 N 81,299.00 350.00
19.01.2009 31 N 81,735.00 436.00
18.02.2009   E 82,130.00 395.00
19.03.2009 59 N 82,537.00 802.00
19.04.2009   E 82,940.00 403.00
19.05.2009 61 N 83,350.00 813.00
Total 181     2,401.00

Total no. of days = 30 + 31 + 59 + 61
  = 181 days
   
Total usage = 350 + 436 + 802 + 813
  = 2,401 units
   
Average usage = 2,401/181 x 30 hari
  = 397.96 units

Note:
  • The total monthly consumption is calculated using the meter readings from the bills with Meter Reading Code N (Normal) only.
  • Electricity usage already billed in the estimate reading (E) is not taken into account when determining the total monthly usage.
  • Average usage is based on a 30-day period.

How the A Bill is Calculated

If Using More Than 400 Units a Month

Suppose your average consumption is 638.29. Your bill will be calculated as follows:-

Actual consumption  = average consumption x duration being billed
= 638.29 / 30 x 30
= 638.29 units
= 638 units (rounded to the nearest integer)

Your A bill will be calculated as follows:

Units used Tariff (RM/kWh) Cost (RM)
First 500 units 0.286 143.00
Next 100 units (501-600 kWj) 0.378 37.80
Next 100 units (601-700 kWj) 0.387 14.71
Total A Bill Amount   195.51
Total After Rounding Adjustment  195.50

If Using Less than 400 Units a Month

Suppose your average consumption is 397.96.  Your bill will be calculated as follows:-

Actual consumption  = average consumption x duration being billed
= 397.96/30 x 30
= 397.96 units
= 398 units (rounded to the nearest integer)

Your A bill will be calculated as follows:

Units used Tariff (RM/kWh) Cost (RM)
First 200 units  0.218 43.60
Next 198 units 
0.334 66.13
Total A Bill Amount   109.73
Total After Rounding Adjustment 109.75
