Tenaga Nasional Bhd (TNB) is stepping up its sustainability efforts under its Net Zero 2050 roadmap, driving multiple renewable energy (RE) initiatives that include hybrid hydro-floating solar projects, hydrogen partnerships, and cross-border renewable power integration.
According to TNB’s chief sustainability officer, Leo Pui Yong, the company is working closely with Petroliam Nasional Bhd (PETRONAS) and Terengganu Inc to advance its renewable energy agenda. Among the key projects is the Hybrid Hydro Floating Solar and Green Hydrogen Hub in Terengganu, launched in July this year, which forms part of TNB’s broader 2.5-gigawatt hybrid solar-hydro initiative.
TNB is also focusing on regional energy collaboration through the Asean Power Grid (APG), aimed at strengthening interconnections and ensuring a stable, sustainable electricity supply across Southeast Asia. The utility giant currently has five major cross-border projects in development, with a combined capacity exceeding 6,000 megawatts (MW) of renewable energy.
One notable initiative is the Vietnam-Malaysia-Singapore interconnection project, which will see renewable energy generated in Vietnam transmitted to Peninsular Malaysia and Singapore. The collaboration involves TNB, PETRONAS, Sembcorp, and Petrovietnam, supporting the APG’s goal of regional energy integration. 
Under its carbon management strategy, TNB is targeting a 5% reduction in emission intensity starting in 2025, and aims to help consumers cut their Scope 2 emissions — indirect greenhouse gas emissions from purchased energy.
Leo emphasized that TNB’s energy transition is not limited to physical infrastructure but also hinges on intelligence, digital connectivity, and human capital.
“TNB remains committed to advancing Malaysia’s energy transition through strategic collaboration, robust governance, and innovation — building a secure, future-ready, and sustainable energy system for all,” she said during the Sustainable Action Conference (SAC) held recently.
