TNB

Tenaga Nasional Berhad (TNB) is Malaysia's largest electricity utility, engaged in generation, transmission, and distribution of electricity. It is headquartered in Kuala Lumpur and is a public-listed company on Bursa Malaysia, with a majority stake held by the Malaysian government and government‑linked investment entities.

The company's origins lie in the National Electricity Board (NEB) that managed power supply across Malaysia. It was corporatized and renamed as Tenaga Nasional Berhad in 1990 as part of Malaysia's restructuring of the electricity sector.

Operations: TNB operates a diverse generation portfolio that includes coal, natural gas, hydroelectric, and renewable facilities, plus a high-voltage transmission network and local distribution to customers in Peninsular Malaysia. It also participates in power trading, project development, and energy services through various subsidiaries and partnerships.

Regulation and policy: TNB's activities are regulated by the Energy Commission (Suruhanjaya Tenaga) under Malaysian law, including tariff approvals and licensing. The company must align with national energy policies, decarbonization goals, and grid reliability requirements.

Challenges and future: TNB faces ongoing modernization of the grid, integration of more renewable energy, fuel-price exposure, and capital-intensive expansion. It remains a central actor in Malaysia's electricity supply and in regional energy projects.
