Building upon the initial TNB-PETRONAS MOU signed on 19 August 2022, the parties are advancing towards a Definitive Agreement for a Joint Feasibility Study focused on green hydrogen as a clean energy alternative. The collaborative study aims to provide a comprehensive understanding of commercial viability, considering factors such as the levelised cost of electricity (LCOE), levelised cost of hydrogen (LCOH), levelised cost ofstorage (LCOS), and the sales price of hydrogen (H2). Our strategy to repower our coal power plants with cleaner technologies is focused on Kapar Energy Ventures (KEV), TNB Janamanjung (TNBJ) and Jimah East Power (JEP). This repowering exercise, which utilises existing sites and infrastructure to generate electricity utilising cleaner technologies such as hydrogen-ready gas power plants and gas power plants equipped with CCS technologies, is expected to reduce our GHG Scope 1 emissions. TENAGA NASIONAL BERHAD Integrated Annual Report 2023 74 Increasing Renewable Energy (RE) Capacity In 2023, TNB’s RE capacity reached 4,375MW, a growth of 16% compared to FY2022 (3,780MW). The announcement of 10 flagship projects under the National Energy Transition Roadmap (NETR) in August 2023 has strengthened TNB’s RE position in the market. i. Championing Green Capacity Growth through Hybrid Hydro-Solar Project (HHFS) The development of around 2,424MW HHFS in four (4) phases at TNB hydro dam reservoirs will increase TNB’s RE capacity.
