Maybe calculate your actual usage. I work from home all the time and my wife 2 of 5 days. My average peak usage is 18.39% for the past 123 days.

Non-ToU also pay the 600 kWh RM10 right?

I get that all the time on Chrome & Firefox. Try private window.

Try other browsers. For me, Safari & Opera are ok.

Can also try to clear browser cache/cookies. I didn't try this.

Don't understand. Didn't you say you didn't change to ToU because "you don't wanna pay the RM10 monthly retail charge because you consume more than 600 kwh per mth."

If 599 kWh and 64% peak usage, it'll be about equal. 23% peak usage, about RM10 savings each month.

What's your peak usage % ?

Yeah, expect to be the same here. The transition bills are quite a bit cheaper.


kWh: 432 - 493 - 388 - 408

Jul is new tariff transition.
Aug is ToU transition.
Sep will be first full month on ToU. Expect 420 kWh or RM120.

You can use mcchin's google sheet to calc. I think KWTBB is just flat 1.6% for 300 & above.

You mean from May to Jun? My cousin also notice jump in kWh after change to smart meter.

Yes, indeed, that's the first one I use. Very well done.

Ya, July bill consider as bonus lah. Drop low bcos of the calculations involved in the tariff change. Look at your kWh instead.

As for smart meter, mine changed 2020, during the few months of relaxed MCO. My recorded kWh didn't differ much though.

Actually, do you have a link to TNB's calculator? I can't seem to find it now.

The energy usage dashboard has gone from bad to worse. Reload, reload, click, reload, reload, reload, reload then too many redirects.

Dunnolah, maybe just luck but last week I managed to download CSV files for 122 days. Today, want to go in to just have a look also cannot.

No "Switch to Domestic Am" button, just 1 button "View Account Details". Ya, how to change back if need be.

Did you received Application Success email? Mine is like this.

Day 1 AM: Apply
Day 1 PM: Received bill for RM10 stamp and paid. Followed by Application Success email.
Day 3: Received Interim Bill. Basically bill for non-ToU usage.
Few days later: Received ToU bill for the remaining days in my billing cycle.

Also, forgot which day, but Energy Usage dash changed to showing peak/off-peak.

What is the status of your "Change Tariff" application in "Apply"->"I want to check my application status" ? Must have got stuck for some reason.



I just checked another house. Even after application successful email, the "2 colour bar" doesn't show until after the interim bill has been issued.

Ya, looks like TNB screwed up there. After "Site Verified", mine was "Reading Interim Bill". Maybe somehow they couldn't get that done, that's why need to change the meter again.

I believe so but I think have to go TNB shop to change. Can't find a way to change back to non-ToU on the website. Maybe can do via ticket?

Also every time change, need to pay Stamp Duty RM10.

This is the Excel 365 Mac file that I use to calc my average usage. Thought I share it here.

• Noob spreadsheet. Before this I've only ever used +_/* and SUM in Excel.
• No VBA so it's safe. (sos: trust me bro)
• Get your daily usage from TNB Energy Dashboard - [View Energy Usage] button and paste into the table.
• You may need current versions of Excel since I use some relatively newer functions like TAKE.
• Ya, I know, I found out later that I didn't have to split DateTime to 2 separate columns.

20250821_1625: Updated xls - just more reference info and fix old tariff tab a bit.
20250829_1706: Cleaned up the xls. Fix some logic errors. Left a months sample data in the table. Delete and add your own.

Thanks for the heads up. Next month check. Already received non-ToU interim bill but it's only for 1-day, 40kWh so no SST. Expect remaining ToU days to be around 1100 kWh.

Almost all ppl should get cheaper bills with ToU unless you go over approx 63% peak usage.

can use mcchin's google sheet to check your bills for old, new and ToU tariffs. What's your typical kWh for a month?

I posted an Excel spreadsheet to calc peak % based on the daily data that you can dl from TNB web.

So far, switch to ToU, app cannot, web only.
