Industrial customers at medium and high voltages (tariff E1, E1s, E2, E2s, E3 and E3s)
Starting from 1 January 2017 Industrial customers at low voltage (tariff D and Ds)
Note: However, low voltage Industrial customers may opt for the ETOU scheme starting from1st January 2016, provided that they would upgrade to medium voltage tariff at their own cost.

Who are the customers eligible for TOU and ETOU tariff scheme?
TOU tariff scheme is offered to MV and HV customers under the following tariff category:
Commercial : Tariff C2
Industrial : Tariff E2, E2s, E3, E3s
Agriculture : Tariff H2
Mining  : Tariff F2

Commercial : Tariff C1, C2
Industrial : Tariff D, Ds, E1, E1s, E2, E2s, E3, and E3s

Why do the tariff rates vary with time periods?
Demand for electricity will be different throughout the day therefore the electricity production cost will also change with time.
For example: During Peak hours, the demand for electricity is high and therefore higher cost of generation will be incurred to generate the electricity to supply to the customers. Thus, the Peak hour rate will be higher than Mid-Peak and Off-Peak rate.

Will ETOU implementation eliminate the TOU tariff scheme?
No. The ETOU scheme is offered as an option to interested customers.

Will the TOU customers be switched to ETOU tariff scheme automatically?
No. TOU customer must apply to TNB for the ETOU tariff scheme.

What is the objective of ETOU implementation?
The objective of ETOU is to encourage Demand Side Management.
ETOU allows customers to manage their electric consumption efficiently by using less electricity during Peak hours.

What are the benefits of ETOU to the customers?
ETOU is a self-regulating tool for customers to control their electricity usage and bill.
Customers will enjoy the reduction in monthly bill by shifting their consumption to Mid-Peak and Off-Peak hours, when the rates are lower

If I choose to enrol to the ETOU scheme, can I revert to the previous tariff scheme?
Customers must be committed to stay in the ETOU scheme for a minimum of 6 months.
After 6 months, customers have the option to cancel their ETOU tariff scheme and revert to the previous tariff scheme; and all cost associated will be borne by them.

Will there be any special ETOU rates for the Special Industry Tariff (SIT) customers?
No. SIT customers will be offered the same ETOU rates offered to non-SIT customers.

Can a customer be on Special Industrial Tariff (SIT) and ETOU scheme at the same time?
No. Customer must choose either one of the applicable tariff scheme for their respective account.

Is ETOU compulsory to all customers?
No.  ETOU will be offered as an option for eligible customers.
Customers must choose the appropriate tariff scheme that best suits their energy consumption.
