Unlock Savings with TNB's Time-of-Use (ToU) Tariff Scheme

Are you a Peninsular Malaysian household looking to lower your electricity bill? Tenaga Nasional Berhad (TNB) has introduced the Time-of-Use (ToU) tariff scheme, offering significantly cheaper electricity rates during off-peak hours. This scheme is part of a broader restructuring of electricity tariffs, designed to encourage consumers to shift their electricity usage to times when demand is lower.

What is the Time-of-Use (ToU) Tariff Scheme?

The ToU scheme essentially divides the day into three periods: peak, shoulder, and off-peak. Each period has a different tariff rate. By strategically using your electricity appliances during off-peak hours (typically late night and early morning), you can enjoy substantial savings. Understanding these periods and how they impact your bill is key to maximizing the benefits of the scheme.

Peak Hours: When Electricity is Most Expensive

Peak hours are typically when electricity demand is highest, usually during the day when most people are at home and using appliances. During these hours, electricity rates are at their highest.

Shoulder Hours: A Transition Period

Shoulder hours are the periods between peak and off-peak times. The rates during these periods are somewhere in between the peak and off-peak rates.

Off-Peak Hours: Your Opportunity to Save

Off-peak hours are when electricity demand is lowest, often overnight. This is when TNB offers the most attractive rates, allowing you to significantly reduce your electricity expenses.
