Who We Are

As the largest electricity company in Malaysia and a leading utility entity in Asia, TNB is indeed the keeper of the light for everybody in Peninsular Malaysia, whether it is commercial or domestic consumers, be it in rural or urban areas. Since its inception, TNB has enabled Malaysia to transform itself into the economic powerhouse that it is today. Tracing its origins to the establishment of the government-run Central Electricity Board in 1949, TNB was later privatized and publicly listed in 1990. Since then, the company has expanded operations and accumulated assets estimated at nearly RM132.9 billion currently. As much as it has provided stable returns to its investors, TNB has stayed focused on supplying Malaysians with a reliable source of energy. In fact, the company takes pride in lighting up 99.9 percent of Peninsular Malaysia.

With approximately 35,684 employees and around 9.2 million customers, TNB has received a string of prestigious accolades for its service and performances, both domestically and abroad. 

Operating mainly in power generation, transmission and distribution, TNB is present in Saudi Arabia, Kuwait, Pakistan, Indonesia and East Asia. Recently, TNB has expanded its global footprint in Turkey and India. In addition, TNB is also actively expanding into other emerging markets, with a focus on the Asia Pacific, Middle East and North Africa regions.

Maneuvering the growth of the conglomerate is the company's subsidiaries such as TNB Repair and Maintenance Sdn. Bhd. (REMACO), TNB Engineering Corporation Sdn. Bhd. (TNEC), Tenaga Switchgear Sdn. Bhd. (TSG), Malaysia Transformer Manufacturing Sdn. Bhd. (MTM), TNB Engineering Services Sdn. Bhd. (TNBES) and Tenaga Cable Industries Sdn. Bhd. (TCI), which have managed to penetrate its key markets, since back in the 90's.

Aside from the six thermal stations and three hydroelectric plants in the country, TNB manages and operates the Malaysia's National Grid and through that system, also maintains interconnection to neighbouring Thailand and Singapore. 

The six thermal power stations comprise coal, conventional gas and oil-fired plants, as well as open and combined cycle gas turbine plants. The generation arm of TNB has a total installed capacity of 12,013.4MW, with 96 percent coming from the thermal plants.

As part of a 20-year strategy plan to become one of the world's largest power companies by 2025, TNB has also committed itself to implementing green initiatives and developing renewable sources of energy, which complements Malaysia's target of lowering overall carbon emission by 40 percent by 2020, in line with most of the mature economies in Europe.
