This page is part of our public exclusion list — a transparency tool that shows which companies we screen out and why. It is not investment advice, and it is not an accusation. But it is subject to change as our understanding of the facts evolves.
Tenaga Nasional Bhd is Malaysia’s national power utility, controlling over 60% of the country’s electricity generation, transmission, and distribution. Coal-fired power generation remains a dominant part of its portfolio, with the company operating multiple large-scale coal plants, including the 2,100 MW Jimah East power station and the 3,100 MW Manjung power station complex. The company is also constructing two new 1,000 MW coal-fired units in Manjung, Perak, to meet rising electricity demand.
While Tenaga Nasional has announced an energy transition plan aiming for a 50% reduction in coal generation capacity by 2035, its current operations and near-term investments remain heavily reliant on coal. The company actively procures significant volumes of coal on the international market to fuel its generation fleet. As Malaysia’s primary electricity provider, Tenaga Nasional’s continued operation and expansion of coal-fired capacity represents a material and ongoing commitment to the most carbon-intensive form of power generation.
Tenaga Nasional Bhd (TNB) is Malaysia's primary electricity utility, with an installed capacity of approximately 27 GW. Its generation mix remains heavily reliant on fossil fuels, with gas and fuel accounting for about 78% of the national energy mix as recently as 2017. The company has announced plans to develop 5,700 MW of new combined-cycle gas turbine capacity, signaling a continued commitment to fossil gas infrastructure. While TNB is undertaking grid planning enhancements to support higher renewable energy penetration and has publicly discussed a transition to a green economy by 2050, its current operations and announced near-term investments are anchored in fossil fuel generation.
Tenaga Nasional Bhd (TNB), Malaysia's primary electricity utility, faces significant operational costs and environmental impacts from river pollution affecting its hydroelectric dams. The company reports spending approximately RM40 million annually to address pollution issues that threaten its power generation facilities. This ongoing expenditure indicates persistent contamination of water resources, which can lead to ecological damage in the reservoirs and surrounding habitats.
A 2022 report specifically notes TNB continues to contend with unforeseen costs in running its hydro dams due to pollution concerns. While the provided evidence does not detail a single catastrophic spill, the recurring financial impact and operational challenges point to documented, systemic environmental harm linked to the company's infrastructure. The case of *Tenaga Nasional Bhd v. Jeffry bin Hassan & Ors* has also been cited in legal reviews concerning environmental damage claims, though the specifics of the ruling are not detailed here.

The Naughty List
A digest of changes to our exclusion list — new additions, removals, and the evidence behind them. We review the list continuously as new evidence surfaces.
Companies appear on our exclusion list based on our investment judgment — not because they've done anything illegal. This is a difference of values and opinion, not an accusation of wrongdoing. Exclusion does not constitute a recommendation against investing in any company, and absence from the list does not constitute a recommendation to invest.
