Electricity Tariff Classification

In general, TNB electricity tariff classification is based on consumer business activity at the said premise and its supply voltage level.  In the event there is changes in activity at the said premise which requires change in consumer tariff category,  the following actions may be taken;

  1. Consumer may apply for change of tariff to TNB
  2. TNB deserves the right to change consumer's tariff based on actual activity at the said premise

    For example, the default tariff for properties or premises such as serviced apartments, SOHO, SOVO and SOFO is Tariff B - Low Voltage Commercial Tariff as these premises are normally built on gazetted commercial lands. However if these premises are used for private dwelling purposes, the owner of these premises may apply for a change of tariff  from Tariff B to Tariff A - Domestic with TNB. Application can be done online via myTNB Portal or at the nearest Kedai Tenaga.

Summary of TNB tariff classification  as follows;

1. Customer category (business activity)

  • Domestic
  • Commercial
  • Industrial
  • Mining
  • Street lighting
  • Specific Agriculture

2. Supply voltage

Top-Up and Standby Services (only for co-generators)

Read up to know more on Top-Up and Standby Services for Co-Generators.
READ MORE

“Co-generator”means a generator who that uses a single primary energy source to sequentially generate two different forms of useful energy for its own use at an efficiency rate of more than 70%. Services offered to co-generators are:

Top-up supply: The additional supply required by a Co-generator who that does not produce sufficient electricity for its own use.

Standby supply: The supply that TNB provides to a Co-generator in the event that the Co-generator does not generate electricity due to plant failure or planned shutdown for maintenance.
