Submit the TOU application on 28 Aug 2025, then received an email for my application for payment on 29 Aug 2025.

Then I make payment via myTNB app on 30 Aug 2025.

Today received the status update, my application got cancelled.
Has anyone encountered this before? What's went wrong?

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.

Ya, called TNB, the CS checked and call me back and told me that she was not able to find out why the application got cancelled.
Hence she help to raise a report, so need 3 working days for TNB to respond and call me.

Just minutes ago while I typing this, weird thing happened, I received the same payment email I received on 29 Aug again, while the case status remains as cancel.
Really tak tau apa sudah jadi.. haha...

sharing this incase someone ask again. added to first post also

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?

Yeah. Old tariff / new tariff (June / July bill) is prorated SST even both sides 14 days for me. Meaning 300kWh is without SST for each bill.

So it’s matter if they want to do it or not. I guess everyone is very sensitive during old tariff to new tariff, if all charge SST sure will show price increase.

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.

Actually dont really understand the whole pro-rated bill kena SST situation. Can help explain with example? Is there a way to avoid the SST if want to switch to ToU?

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.

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.

Thanks for the research and explanation. Will add this to first post also

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

Once upon a time before Smart Meter the meter reader came to read my meter shorter than 28 days

My bill kena SST

I complaint this is not my problem who asked the interval you come to read so inconsistent

at the back they sure said

Are we supposed to see how many kwh we used during peak and non peak hour on the usage graph on myTNB app after switching to ToU?

Already successfully switched over on Tuesday. Check the app just now and can see there's a separation on the graph for yesterday's usage.... but the tariff rate still showing the normal domestic rate

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.

This post has been edited by soonwai: Sep 11 2025, 12:34 AM

Hopefully they improve it soon.... no point we see the normal rate when we already on ToU

So for the bar I would assume the big portion is off peak.... small portion is peak? They didn't specify a colour to indicate what it means also... probably it's still work in progress for TNB and the next app update can see some improvements

The view smart meter usage on myTNB website is better (if it works correctly), hopefully we able to view the ToU usage on myTNB app soon as well

I wonder whether tomorrow 15th public holiday is counted for whole day off peak or normal peak/off-peak rate?
