T otal renewable energy (RE) made up 8.3% of the total electricity sent out in 2023, a slight decrease from the 8.7%in 2022. In alignment with our Reimagining TNB strategy and Energy Transition plan, we have continued to uphold the operational excellence of our conventional and RE generation fleet, explored new collaborations to decarbonise our thermal plants in Malaysia and forged ahead with acquiring and developing new RE assets. DOMESTIC GENERATION BUSINESS UPDATE Operational Performance Update In 2023, TNB Power Generation Sdn. Bhd. power plant availability factor in Peninsular Malaysia was 83.3%, a slight improvement from the 83.2% recorded in 2022. The improvement was mainly contributed by the continual optimisation of the planned outages at our thermal plants. The plant availability factor was significantly affected after one of our major power plants, the TNB Janamanjung 1GW coal-fired plant, experienced an unexpected outage in December 2023. Remedial actions are already underway, and we will be striving to rectify this issue as early as possible to resume plant operation. Prior to this, our plant availability factor had improved by 1.5% quarter-on-quarter in Q3 2023, due to lower unplanned outages during the period, which contributed to a 43.6% quarter-on-quarter
