Crazy Rich Malaysia | Sarawak Hydropower, Hydrogen and the Renewable Industrial Economy begins with rivers.
Did you know Sarawak Energy says hydropower typically supplies about 65% of electricity to the Sarawak grid? Its major hydroelectric plants include Batang Ai, Murum and Bakun, while the 1,285 MW Baleh Hydroelectric Project is under construction and scheduled for commissioning by the fourth quarter of 2030.
That makes “Sarawak hydropower”, “Bakun Dam”, “Baleh Hydroelectric Project”, “Sarawak renewable energy”, “green hydrogen Sarawak”, “Sarawak Energy”, “Bintulu hydrogen” and “Sarawak energy transition” powerful search themes. But the richer story is not the dam.
It is how abundant electricity can become industrial strategy.
Crazy Rich Malaysia can begin upstream.
Did You Know? Hydropower Turns Geography into Industrial Capability
Sarawak’s rivers, rainfall and topography create conditions suitable for large-scale hydropower.
That changes what the state can offer industry.
Electricity becomes more than a household utility.
It becomes an input into:
- heavy industry;
- metals processing;
- data centres;
- hydrogen production;
- export-oriented manufacturing;
- electrified transport; and
- regional power trade.
The river therefore becomes an industrial input before the factory is even built.
Bakun Is the Giant in the System
Bakun Hydroelectric Plant is Sarawak’s largest operating hydropower station.
Sarawak Energy lists its installed capacity at approximately 2,520 MW.
That scale matters because very large electricity users need confidence that generation capacity exists before they commit billions of ringgit to factories.
Large hydropower therefore supports a different kind of industrial policy.
Instead of asking only:
“Which industries already operate here?”
Sarawak can ask:
“Which electricity-intensive industries become possible because this power exists?”
Murum and Batang Ai Make the Grid a Portfolio Rather Than a Single Dam
Sarawak’s hydropower system includes Murum at around 944 MW and Batang Ai at about 94 MW, alongside Bakun.
This matters because electricity systems are stronger when they do not rely on a single generating asset.
Different reservoirs, catchments and plants create operational flexibility.
The grid can balance:
- hydrological conditions;
- maintenance schedules;
- industrial demand;
- household demand; and
- thermal generation when needed.
One dam creates power.
A portfolio creates system resilience.
Dry Weather Shows Why Renewable Does Not Mean Risk-Free
In August 2026, Sarawak Energy said prolonged dry weather had reduced inflows into the Bakun, Murum and Batang Ai reservoirs.
Hydropower still supplied about 65% of electricity under typical conditions, but during dry periods the system can reduce hydro output and increase thermal generation to conserve reservoir levels.
This is a useful reminder.
Renewable energy systems still have physical constraints.
Solar depends on sunlight.
Wind depends on wind.
Hydropower depends on water.
The engineering challenge is not to eliminate nature.
It is to design enough flexibility that the system remains reliable when nature varies.
Baleh Adds Another 1,285 MW of Renewable Capacity
The Baleh Hydroelectric Project is one of Sarawak’s largest infrastructure projects.
Sarawak Energy says the 1,285 MW project is scheduled for commissioning by the fourth quarter of 2030.
The project includes a massive concrete-faced rockfill dam and a reservoir extending across hundreds of square kilometres.
Its importance is strategic.
Baleh expands renewable capacity at the same time Sarawak expects more demand from:
- industry;
- economic development;
- new-energy projects;
- regional electricity exports; and
- future low-carbon manufacturing.
Power investment comes before some of the industries it is meant to attract.
Infrastructure creates option value.
Sarawak Wants 10 GW by 2030 and 15 GW by 2035
Sarawak Energy has described targets of reaching 10 GW of installed capacity by 2030 and 15 GW by 2035, with renewable sources targeted at no less than 60% of the capacity mix.
This is much larger than a utility expansion plan.
It signals an economic ambition.
More electricity means the state can support more:
- manufacturing;
- industrial parks;
- digital infrastructure;
- electrified transport;
- hydrogen production; and
- exports.
The grid becomes a growth platform.
Cheap Renewable Electricity Attracts Electricity-Hungry Industry
Sarawak’s industrial strategy has long used competitively priced electricity as an investment advantage.
Some industries care enormously about power cost because electricity is a major production input.
Examples include:
- metal smelting;
- electrochemical processes;
- data centres;
- hydrogen electrolysis;
- large-scale processing; and
- other energy-intensive manufacturing.
This creates a direct link between the river and the factory balance sheet.
Energy geography becomes investment geography.
Hydrogen Turns Electricity into a Tradable Molecule
Hydropower creates electricity.
Electrolysis can use that electricity to split water and produce hydrogen.
This creates an important new possibility.
Electricity is difficult and costly to transport over very long distances without transmission infrastructure.
Hydrogen—or derivative products such as ammonia—can potentially carry renewable energy in chemical form.
Sarawak’s Hydrogen Economy Roadmap explicitly builds on the state’s hydropower advantage.
The economic logic is elegant:
river → electricity → hydrogen → industrial feedstock or export.
H2ornbill Is One of Sarawak’s Flagship Hydrogen Projects
Sarawak’s current development planning identifies H2ornbill as part of the state’s hydrogen-hub strategy.
The plan describes a collaboration involving SEDC Energy, Sumitomo Corporation and ENEOS Corporation.
Current planning documents cite a target of roughly 88 kilotonnes of clean hydrogen production annually for the project.
These are forward-looking project targets rather than completed production.
That distinction matters.
Energy transition announcements often describe intended capability.
The real test is whether projects achieve financing, engineering, construction, customers and reliable operation.
Hydrogen Needs Customers, Not Just Electrolysers
Producing hydrogen is only half the economic system.
Someone has to use it.
Potential uses include:
- industrial feedstock;
- fertiliser and ammonia production;
- steel and other hard-to-abate industry;
- heavy transport;
- shipping fuels;
- energy storage; and
- export to markets seeking low-carbon fuels.
This is why Sarawak’s hydrogen strategy focuses on both supply and demand.
An electrolyser without an offtaker is machinery waiting for an economy.
Hydrogen Certification Could Become a New Trust Infrastructure
Not all hydrogen has the same carbon intensity.
That creates a measurement problem.
If a buyer pays a premium for low-carbon hydrogen, the buyer needs evidence about how it was produced.
Sarawak’s current roadmap includes plans for a certification platform for hydrogen exports.
This is conceptually similar to halal certification or sustainable commodity traceability.
The physical product is hydrogen.
The premium depends partly on trusted information about the product’s origin.
Data becomes part of the molecule’s commercial identity.
Sarawak’s Grid Is Also a Regional Asset
Sarawak already participates in regional electricity trade within Borneo.
Regional interconnection matters because electricity systems become more flexible when they can exchange power across wider geographies.
One region may have spare supply while another needs more.
Interconnectors can create:
- export revenue;
- larger balancing areas;
- greater resilience; and
- a pathway toward deeper ASEAN power integration.

Hydropower Has Environmental and Social Trade-Offs
Large dams can create low-carbon electricity.
They can also transform rivers, ecosystems and communities.
Reservoirs inundate land.
Fish movement can change.
Downstream flows can be altered.
Communities may face resettlement or livelihood changes.
That is why modern hydropower increasingly uses sustainability standards, environmental assessment and long-term community engagement.
Sarawak Energy says Baleh is being developed against international hydropower and dam-safety standards.
The relevant question is not whether dams have impacts.
They do.
The question is whether the value created justifies the costs and whether avoidable harm is reduced intelligently.
Hydropower and Solar Solve Different Parts of the Renewable Puzzle
Solar output follows sunlight.
Reservoir hydropower can be more dispatchable because operators can control when water passes through turbines within hydrological constraints.
That makes hydro and solar potentially complementary.
Solar can produce strongly during daytime.
Hydro can help balance the system when solar varies.
Sarawak has also explored floating solar around hydropower assets.

The richer renewable system uses different technologies for different constraints.
The Data Centre Boom Makes Sarawak’s Energy Advantage More Interesting
AI and cloud infrastructure are electricity-intensive.
That gives regions with reliable, competitively priced, lower-carbon electricity a strategic advantage.
Johor currently dominates Malaysia’s data-centre expansion story.
But the deeper national question is broader:
where can Malaysia create enough clean, firm electricity to support future compute and industrial demand?

Energy abundance becomes compute possibility.
Sarawak’s Energy Economy Is an Education Economy
Dams, grids and hydrogen plants require deep technical capability.
- civil engineers;
- electrical engineers;
- hydrologists;
- geologists;
- environmental scientists;
- grid operators;
- chemical engineers;
- hydrogen specialists;
- technicians; and
- project-finance professionals.
The dam is concrete.
The capability behind it is human.
The richer energy system is the one that can design, operate, repair and improve itself locally.
