- Tenaga Nasional Berhad operates as Malaysia's largest electricity utility, leading the energy sector across Asia with a robust presence in multiple countries. The company comprehensively manages electricity generation, transmission, distribution, and retail sales. Its generation portfolio includes significant thermal facilities utilizing coal and natural gas, major hydroelectric schemes in Peninsular Malaysia, and a growing number of renewable energy assets, including solar, wind, and hydro projects, domestically and in the UK, Turkiye, and India. TNB Power Generation Sdn Bhd (TNB Genco) contributes nearly 51% of Malaysia's power generation capacity. TNB also operates and maintains Malaysia's National Grid, which provides interconnections with power systems in Thailand and Singapore. The company serves over 10.6 million residential, commercial, and industrial customers throughout Peninsular Malaysia, Sabah, and Labuan. Beyond core electricity supply, TNB offers diverse energy-related services, including supplying fuel for power generation and providing specialized operation, maintenance, repair, and overhaul (MRO) services for power plants and heavy industries, with international engagements in countries such as Kuwait, Pakistan, and Cambodia. It also undertakes engineering, procurement, construction, and commissioning (EPCC) projects, develops district cooling systems, and operates co-generation facilities. In manufacturing, TNB produces, sells, and repairs various types of transformers, manufactures and distributes power and general cables and aluminum rods, and assembles high and medium voltage switchgears for electrical power transmission and distribution. Additionally, the company is involved in managing dry bulk terminals. The utility extends its capabilities to other sectors, offering telecommunication and IT infrastructure solutions, providing higher education through Universiti Tenaga Nasional (UNITEN), and conducting extensive research and development in engineering and technology. It also delivers training courses and provides insurance and reinsurance products through subsidiaries. TNB maintains a strategic focus on energy transition, aiming for Net Zero emissions by 2050 and a 35% reduction in emissions intensity by 2035. Recent initiatives include a memorandum of understanding with State Grid Corporation of China for technology cooperation, a full feasibility study with Singapore for a second power interconnection, and the maiden export of renewable energy to Singapore. The company recently uncovered over $1.1 billion in losses from electricity theft related to illegal cryptocurrency mining between 2020 and 2025, leading to the deployment of smart meters and a tracking database to combat this issue. Established in 1949, Tenaga Nasional Berhad is headquartered in Kuala Lumpur, Malaysia.
