anyone bill more expensive this month? last month usage 400kwh rm96, this month usage 402kwh but rm122...?

under old tariff 400kwh should be around rm122. perhaps recheck any special rebate or discount you get from previous month?
or they mess something up last month as that's the transition month (partial old tariff partial new tariff)

Don’t look at last month bill… last month is half half prorated.
They actually charge lower giving more rebate with the prorate here and there. If you take last month bill (full combined kWh) and put in old tariff calculator and new tariff calculator, you won’t get that low amount they charged.

Worth taking if use less than 600kwh/month?

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 % ?

july usage rm130

june usage bill was too low rm109. july usage rm130 (normally this figure)
every month 400kwh above

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.

my bill came today - only 15 days of usage
I calculated I save about RM5.85 for ToU. Not sure how to calculate KWTBB though
Hopefully will see a better picture next full month

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.

the faaking JMB have a rule saying they won't switch for smart meter .. impacting those who want to switch

TNB website have their own calculator and its accurate. Can calculate both ToU and non ToU

i change to smart meter quite some time ago.. not recently..

and yes from May to June jump.. but june was very hot month and memang got use more air-cond, so i can understand if bill higher..

but then July bill drop till 127 damn low.. and then now August jump back up to 187..

It feels like the smart meter damn wonky..

Bro you not smart meter consider good ler..

like the poster above said and including my own experience, i notice ever since change to smart meter my bill on average increased by about 10~20 bucks every month..

My condo not that old, 2016 till now.. Was changed to smart meter last year iirc..

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.

Scroll down to find the button Kalkulator bill anggaran.

On the right hand lower corner you will see the calculator blue button, just press it.
