Sustainable Infrastructure & Ecosystem
TNB's key focus is to accelerate the energy transition and address climate change by digitalising the utilities industry, utilizing efficient technology, and exploring greener energy sources for enhanced power security.
Generation Fuel Mix

TNB's generation fuel mix depends on the Peninsular Malaysia’s Generation Development Plan as approved by the Planning and Implementation Committee for Electricity Supply and Tariff (JPPPET), which is chaired by the Ministry of Natural Resources, Environment and Climate Change (NRECC). This plan is developed based on the underlying principle of balancing the security of electricity supply, affordability and environmental sustainability. TNB’s target on renewable energy growth aligns with the nation's goal of increasing renewable energy capacity and reducing the greenhouse gas emission intensity of GDP by 45% by 2030.

Smart Grid

The Grid of the Future (GoTF) strategy, which is a part of TNB's Energy Transition Plan, aims to modernise and digitalise our grid and distribution infrastructures to support increased integration of distributed generations and renewables. This will lead to enhanced reliability and efficiency of our distribution network and system in delivering services to our customers. This is achieved by better management of distributed generation and possible interconnections with other countries. Additionally, digitalization opens up possibilities to offer new products and services to meet our customers’ needs and expectations.

Sustainable Business Expansion
Our sustainability journey towards Net Zero Emissions by 2050 focuses on ESG pillars integrated into our Reimagining TNB (RT) corporate strategy and business operations.
The TNB Energy Transition (ET) Plan, an extension of the RT, strengthens our sustainability journey by focusing on three (3) strategic pillars supported by critical enablers in shifting from a fossil-based energy mix to greener energy sources. These initiatives cut across the electricity value chain, from transitioning power generation to cleaner sources, enhancing the Develop Energy Transition Network, enabling more green solutions and facilitating consumer participation in the energy transition, including digitalisation and electrification.
