Whoever changing to TOU just putting it here so that don't get bill shock.

Everytime you change TOU, there will be cutoff and prorated bills.

Every prorated bill <28 days, all kWh will be charged SST 8%
I received my prorated bill 27 days today and all my 676kWh is fully charged 8%. So every time you change between TOU and non-TOU,
+ RM10 stamp duty
+ Additional 8% SST on your bill. No without SST for first 600kWh even prorated.

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. This will ensure no SST for the 1st interim bill but cannot avoid SST for the 2nd interim/final bill.

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

What is the rate, and what is the time?

If peak = 5.0, off peak = 4.9. Then DLLM lah.

If you are away from house during weekday, children going to school during weekday - yes, opt in.

If you work from home, children at home regardless weekdays or weekend  - perhaps opt out.

If at home but no use aircond? I believe the consumption from lights and fans should be negligible

peak: 2pm-10pm
offpeak: 10pm-2am(typo in the image?)

weekend:offpeak all day(24hours)

No other appliances like washing machine, dryer , water heater, iron , oven ?

If from light & fans - yes, very small consumption.

i still dont get it, if during peak but already low consumption since no one at home, why opt in?
