Would Time-of-Use cut your home bill?

Three quick questions.

1Your monthly TNB bill?

2When do you use most power?

3What could you run after 10pm or on weekends?

Important: bigger savings need lifestyle changes

Switching tariff alone saves little for most homes. To save more, you have to change when you use electricity, by moving it to after 10pm or onto weekends. For example:

Run the washing machine, dryer and dishwasher after 10pm or on weekends.
Set your EV to charge after 10pm instead of when you get home.
Pre-cool bedrooms before 2pm, and go easy on the aircon between 2pm and 10pm on weekdays.
Do heavy cooking and heat water outside the weekday 2pm–10pm window.

If these changes don’t suit your routine, Time-of-Use can cost you more than the standard tariff.

How this is calculated

Peak is 2pm–10pm Monday–Friday. All other hours, weekends and public holidays are off-peak.
ToU peak is 1.49 sen/kWh dearer than standard; off-peak is 2.60 sen cheaper. Capacity and network charges per kWh are the same on both tariffs.
Your bill is converted to kWh using a typical all-in price of RM0.44 per kWh. Rates: TNB RP4, from 1 Jul 2025.

An indicative estimate, not a quotation or an offer. Based on TNB RP4 rates from 1 July 2025 (Peninsular Malaysia); rates and monthly adjustments can change. Helios is not affiliated with TNB. Nothing you enter here is stored or sent anywhere.
