Hydropower in Malaysia: Distribution, Projects & Market Opportunities | Hydget Power Solutions
Hydropower in Malaysia: Regional Distribution, Development Trends & Equipment Opportunities
Malaysia's hydropower sector is undergoing a strategic transformation as the country works toward its ambitious renewable energy targets. With a current installed hydropower capacity of 6,372 MW generating 32 TWh annually, Malaysia aims to significantly expand this clean energy source as part of its National Energy Transition Roadmap (NETR). The country plans to increase renewable energy share to 31% by 2025 and 70% by 2050, creating substantial opportunities for electrical equipment suppliers in transformers, switchgear, and grid infrastructure.
Market Insight: Malaysia requires investments of MYR 637 billion (∼USD 135 billion) between 2023-2050 for renewable energy expansion and grid modernization. The hydropower segment alone has an estimated technical potential of 29,000 MW – over four times the current installed capacity – positioning it as a cornerstone of the country's energy transition strategy.
Regional Distribution of Hydropower Resources
Peninsular Malaysia: Modernization & Hybrid Solutions
Operated primarily by Tenaga Nasional Berhad (TNB), this region focuses on upgrading existing infrastructure and deploying innovative hybrid solutions:
Hybrid Hydro-Floating Solar: TNB is developing 2.5 GW of hybrid projects at its hydropower dams, starting with a 30 MW pilot at Chenderoh reservoir, followed by Temenggor and Kenyir reservoirs.
Life Extension Program: A MYR 4 billion (USD 850 million) modernization of three hydropower stations (Temengor, Bersia, Kenering) will increase output by 15% and extend operational lifespans. The project includes turbine-generator rehabilitation and control system upgrades.
Sarawak: ASEAN's "Green Battery" Ambition
With 3,500 MW of installed hydropower capacity lighting 2-3 million households, Sarawak Energy Berhad (SEB) is positioning the state as a regional renewable energy hub:
Cross-Border Exports: A 128-km transmission line already exports hydropower to Indonesia, with plans to expand connections to Brunei, Singapore, and the Philippines.
Floating Solar Expansion: After commissioning its first 50 MW floating solar unit, Sarawak plans additional installations across its hydropower reservoirs.
The state aims to reach 10,000 MW of renewable capacity by 2030, primarily from hydropower, to supply neighboring regions.
Sabah: Strategic Partnerships for Rural Electrification
Sabah Electricity Sendirian Berhad (SESB) is developing the 187.5 MW hydropower plant in Tenom through a joint venture with Gamuda. Key features include:
Capacity: 1,052 GWh annual generation starting 2029
Investment: RM 4 billion (USD 850 million)
Technology: Three vertical Kaplan turbines (24MW each) and Francis turbines (40MW each)
Innovative Hybrid Hydro-Solar Projects
Malaysia is pioneering hybrid hydro-floating solar (HHFS) technology to maximize reservoir utilization:
Tasik Kenyir HHFS Plant: A 500 MW project combining floating solar with existing hydropower. This integrated approach enables continuous renewable generation – solar during peak daylight and hydro during night/peak demand.
Technology Synergy: HHFS systems use hydropower infrastructure for grid connection, reducing deployment costs by 25-30% versus standalone solar farms. The hydropower component also provides natural storage for balancing solar intermittency.
Modernization of Ageing Infrastructure
With over 50% of Malaysia's hydropower assets over 30 years old, a systematic Life Extension Program (LEP) is underway:
Key Modernization Projects:
1. Temengor Hydropower Station (4×100MW Francis turbines): 15% capacity increase through turbine optimization and control system upgrades
2. Bersia Plant (3×24MW Kaplan turbines): Automation system overhaul for cascade river station control
3. National SCADA Implementation: Real-time monitoring across 117 facilities to improve grid stability
Hydropower in Malaysia's Energy Transition
Hydropower serves multiple strategic roles in Malaysia's clean energy shift:
Grid Stabilization: Provides baseload power and frequency regulation for solar integration – critical as Malaysia targets 15,000 MW solar capacity by 2035.
Energy Storage: Pumped hydro potential remains untapped, with theoretical capacity of 5,000 MW identified in mountainous regions.
Green Hydrogen Production: Sarawak is exploring hydropower for electrolysis to position Malaysia as a hydrogen exporter.
