TNB Commences Development Of 500kV National Grid Backbone, Reinforcing Malaysia’s Energy Security and Transition

Tenaga Nasional Berhad (TNB) marked another significant achievement in its commitment to building a future-ready energy infrastructure with the commencement of a new 500kV National Grid Backbone transmission line – a strategic infrastructure project that will reinforce national energy security, accelerate energy transition and accommodate the nation’s future electricity needs.

The launching of the 500kV Transmission Main Intake Substation (PMU) Kampung Awah project site in Maran, Pahang, today marks an important milestone in the development of the National Grid Backbone, which will connect strategic locations across the east coast of Peninsular Malaysia.

The National Grid Backbone is designed to enhance the resilience, reliability, flexibility and transmission capacity of the National Grid, while advancing the implementation of the National Energy Transition Roadmap (NETR).

Upon its completion by 2030, the National Grid Backbone is set to become the longest 500kV transmission system to ever be developed in Malaysia with a total length of approximately 500km.

The launching of PMU Kampung Awah project site was officiated by Pahang Menteri Besar, Dato’ Sri Diraja Wan Rosdy Wan Ismail, and attended by TNB President/Chief Executive Officer, Datuk Ir. Ts. Shamsul Ahmad.
