New Tariff for Electricity (2)

Received a comment from a user of TNB (i think all of us who stay in West Malaysia use TNB unless you use genset to generate your own electricity). I think it is better also for others to check your TNB bill.

Dear Brothers...check the calculation of your TNB Bill

On the 18th July 2008, my electricity usage was read for the period between 13th June to 18th July 2008 and total usage was 631kwh. To my disappointment, the calculation on tariff was bias. The calculation was wrong and because of the reading was made on 18th July 2008, the total period was 35 days, therefore the additional kwh falls under higher tariff. For my analysis, the method of calculation which was explained to me by TNB personnel is to the advantage of TNB.

Details as follows:
Calculation method explained by TNB (1-300-88-5454) on 18th July 2008 betwewn 2:30pm to 2:45pm

Usage 631kwh

Calculation for the period of Jun 2008 (13th June to 31st Jun 2008)
18 days / 35 days * 200kwh (first 200 of the old tariff) = 102.8 => 103kwh
18 days / 35 days * 431kwh (subsequent of the old tariff) = 221.7 => 222kwh

103kwh X 0.218 = RM 22.45
222kwh X 0.289 = RM 64.16
*Usage of 631kwh is calculated for 18 days

Calculation for the period of July 2008 (1st July to 18th July 2008)
17 days / 35 days * 500kwh (first 500 of new tariff) = 242.8 => 243kwh
17 days / 35 days * 100kwh (subsequent of the new tariff) = 48.6 => 49kwh
17 days / 35 days * 31kwh (subsequent of the new tariff) = 15 => 15kwh

243kwh X 0.30 = RM72.90
49kwh X 0.39 = RM19.11
15kwh X 0.40 = RM 5.60
*Usage of 631kwh is calculated for 17 days

Bil sepenuh nya adalah seperti berikut:

103kwh X 0.218 = RM 22.45
222kwh X 0.289 = RM 64.16
243kwh X 0.30 = RM 72.90
49kwh X 0.39 = RM 19.11
15kwh X 0.40 = RM 5.60

Jumlah = RM184.22

*631kwh is being calculated twice even though partial usage falls in the old tariff
The correct calculation should be as follows:
Usage for the period of 13th June 2008 to 18th July 2008 equalvalent for 35 dyas is 631kwh which 18days falls under the old tariff and 17days falls into the new tariff.

18 days/35 days = 0.51
17 days /35 days = 0.49

June 2008 usage 0.51 X 631kwh = 325kwh
July 2008 usage 0.49 X 631kwh = 306kwh

Usage for the period of June 2008 based on the above calculation is 325kwh (Old tariff)

First 200kwh X 0.218 = RM43.60
Subsequent 123kwh X 0.289 = RM36.13

Usage for the period of June 2008 based on the above calculation is 306kwh
(New tariff)
First 200kwh X 0.218 = RM43.60
Subsequent 106kwh X 0.345 = RM36.57

Total bill
June 2008 = RM43.60
June 2008 = RM36.13
July 2008 = RM43.60
July 2008 = RM36.57
Jumlah : RM159.90

7.0 Conclusion
I believe that the calculation method used by TNB is to maximized profit at the expense of the public. It is very confusing and double counting on a single usage. For the public at large, most of them doesn’t know the actual calculation and take what ever method used by TNB.

In my case, why TNB took more than 30days to read the meter. When this happened, the reading will be more and it will fall into higher tariff and this will profit TNB and I have to pay more. Why should this happened?

Why does the usage 631kwh being calculated twice for the period of 13th June 2008 to 30th June 2008, and again being calculated for the period of 1st July 2008 to 18th July 2008? It should take 18days/35 days and this is a factor for June 2008 and 17days/35days will be the factor for July.
The meter reading policy MUST be change with immediate. All meter reading MUST be done within 25th to 30/31th of every month and not to the maximum of 36 days.

When I need to get clarification from TNB Rawang on the 18th July 2008 between 3pm and 3:30pm, there was nobody to come to my aid, telephone was not answered at 036092700. Do I need to travel to TNB Rawang from my office /home which is about 20km away? Will TNB bear my cost? Should I bear the cost when the mistake was made by TNB?

Its clear that TNB wishes to confused the public and make profit based on its calculation method and does care for the public at all.

TNB should be more efficient in doing the meter reading and use a better formula in calculation to avoid misunderstanding among the public.
