Tnb Janamanjung Sdn. Bhd. (Malaysia)

TNB Janamanjung Sdn. Bhd. is a Malaysian power generation company and a wholly owned subsidiary within the Tenaga Nasional Berhad (TNB) group, operating the Sultan Azlan Shah Power Station at Manjung, Perak (also commonly referred to as the Janamanjung or Manjung power station complex). The company's principal activity is the ownership and operation of large-scale coal-fired generation assets configured for baseload electricity supply to Peninsular Malaysia's grid, with design objectives emphasising high availability, operational reliability, and the capability to participate in system frequency regulation in compliance with Malaysian and selected international operating standards. The Manjung power station complex has been developed in phases and has been widely referenced as one of the largest coal-fired power generation facilities in Malaysia, supported by significant fuel-handling, marine logistics interface, and environmental control systems required for continuous utility-scale dispatch. TNB Janamanjung's operational scope covers plant operations, maintenance, performance optimisation, outage planning, safety management, regulatory compliance, and environmental governance, with a focus on efficient and safe operation while managing surrounding environmental considerations. The company's geographic reach is domestic, supplying electricity into the national grid and supporting system adequacy and stability for industrial, commercial, and residential demand centres across Peninsular Malaysia. Strategically, TNB Janamanjung is positioned as a critical dispatchable generation platform within TNB's broader generation portfolio, prioritising operational excellence, cost and heat-rate optimisation, asset integrity and lifecycle management, and compliance-driven performance to meet national reliability requirements during the power sector's longer-term transition toward lower-carbon generation mixes.
