Can. Pay RM10 stamp duty again.

You can go to TNB web to see your energy usage.

If your usage graph is something like this then worth already lah. If want to have a clearer idea, can download the daily usage for many days and calc in spreadsheet. I got attach one Excel a few posts up.

For 850kWh (AFA: -1.45 sen) using mcchin's Google Sheet.

I use 20% peak since that's mine. Of course, yours will be different.

Today TNB came to change my neighbour's smart meter. The technician mentioned it's for ToU but didn't say why had to change again.

Anyway his old smart meter was installed around the same time in 2020 as mine but is different from mine.


Mine is exactly like this.

Neighbour's old one had a bigger green button on the right in place of the 2 white ones and doesn't have that circle feature on the left.

The new one installed today looks similar to mine but has a smaller screen with the 2 white buttons moved up to the immediate right of the screen.

Macam TNB trying many different models. Maybe some not working so well.

Can't do, have to be account owner. So need his IC (back & front) to verify as owner.

Can't do, myTNB login has to be owner verified. Otherwise no "Switch to ToU" button. Need his IC (back & front) to verify as owner.

If myTNB is already owner verified i.e.: has the "Switch to ToU" button then can do even with non-owner IC.

Updated answer, thanks to input from:

TIL while helping neighbour with ToU. He already have IC verified myTNB login but forgot password so proceeded to setup another new login. Verifying this new account again as owner with IC will not work. TNB didn't inform and just marked the service request as Solved. No house number, no energy usage, no switch to TOU button.

In the end, just reset the password for the old login.

That's good, please elaborate what you did so we can learn from you. Did online or at Kedai Tenaga?

More details please.

Thanks boss. That'll make it easier for ppl to apply.

Working but can't apply ToU.

AFA for Sep 2025 is -1.10 sen/kWh.

Less discount than forecasted -1.23.

Forecast:

1 – 31 Oct 2025	-0.0231
1 – 30 Nov 2025	-0.0106
1 – 31 Dec 2025	-0.0288

Update to this. Now I know why TNB changed my neighbour's meter (digital) to new smart meter.

Turns out back in 2020, when the whole road changed to smart meter, my neighbour got caught with tampered meter. So TNB installed another meter to monitor. Now want to change to ToU so TNB installed smart meter. I guess the monitoring meter wasn't a smart meter.

No idea what happened with regard to the tampering.

Interestingly, I told another neighbour, with smart meter (can see usage in web, change to ToU) also installed in 2020, about ToU. He's not going to change because his smart meter is modified. Man, I think 50% of the houses on road have modified meters, old or new. Mine, of course, is

Better call them and ask. Did they call you? No email also?

When I wanted to do Change of Tenant, I accidentally did Owner Verification. Obviously not going to work since bill owner is different from MyKad name. TNB actually called to inform that the request failed because names are different.

Confirm this. Just looked at 3 sets of non-ToU -> Tou interim bills with SST charged even though low kWh. Later I check and update with more details.

Non-ToU -> ToU Bills
1. 88 kWh no SST (28 days) & 9 kWh 9 got SST (3 days)
2. 1310 kWh 710 got SST (31 days) & 40 kWh 40 got SST (1 day)

3. 334 kWh 334 got SST (25 days) & 74 kWh 74 got SST (6 days)

more to come...

Earlier old tariff to new tariff, no such problems right?

kes #2 above, I can understand since 1310 kWh for sure kena SST. Cannot brain why total 88 kWh also kena for the 2nd interim bill of 3 days 9 kWh.

Have raised a ticket to TNB. See what they say.

I also don't understand why. I only have the 3 examples of it happening and can't find any pattern to it. Could be mistake in TNB's calculation logic.

1. 88 kWh no SST (28 days) & 9 kWh 9 got SST (3 days)
2. 1310 kWh 710 got SST (31 days) & 40 kWh 40 got SST (1 day)
3. 334 kWh 334 got SST (25 days) & 74 kWh 74 got SST (6 days)


For #3 above, both bills kena SST.

The only thing I know for sure is SST only charged for usage above 600 kWh. Stated on website and bill.

Exact words on bill are:


inb4: so little money, also make so much noise.

Found this at https://www.mytnb.com.my/faq


Applied to my examples:
1. 88 kWh no SST (28 days)1️⃣ & 9 kWh 9 got SST (3 days)2️⃣
2. 1310 kWh 710 got SST (31 days)1️⃣ & 40 kWh 40 got SST (1 day)2️⃣
3. 334 kWh 334 got SST (25 days):2️⃣ & 74 kWh 74 got SST (6 days)2️⃣

OK, settled lah. Lucky I haven't submitted my ticket yet.

ZeneticX
Conclusion: To avoid SST for those below 600 kWh, do the TOU change on(?) or after the 28th day of your billing period. This will ensure no SST for the 1st interim bill but cannot avoid SST for the 2nd interim/final bill. Can also do at the beginning 1st, 2nd or 3rd day of your billing period but gg if application is delayed.

Alternatively, can move to Pulau Tioman, Pulau Langkawi or Pulau Pangkor.

Update:
For Jun/July bill (old-new tariff transition), dun have less-than-28-days-SST-charge as billing for both before and after were merged into one bill so the bill was 30 days.

Update:
Old style bill actually had this info.

Actually credit to LaiN87. If you look back at his post, he already gave the answer. I just didn't pick up on that.

20250910_1147:
• Updated Excel file.
• Now accounts for off-peak public holidays.
• The single cell formulas are on the Tariff sheet.
• Now includes formulas for old, non-ToU & ToU.

I will post future updates to this thread:

Just that little break in the daily barchart to indicate the peak/off-peak.



You're right, it doesn't show the peak/off-peak rates. Didn't realise that before.

I think no, only 16/9 off-peak.
