Malaysia’s energy system reflects the country’s unusual geography. Peninsular Malaysia contains most of the population, manufacturing base and electricity demand, while Sabah and Sarawak operate separate power systems across the South China Sea. This division has produced several energy stories within one country. Coal and natural gas still dominate electricity generation in the peninsula. Sarawak relies much more heavily on large hydropower plants. Sabah has its own supply and grid challenges. At the same time, Malaysia is an important oil and liquefied natural gas producer, a major refining centre, and one of Southeast Asia’s fastest-growing solar markets.
The central challenge is not simply replacing fossil fuels. Malaysia must meet rising industrial demand, strengthen three different grids and protect the energy revenues that have supported national development.
Three Power Systems Shape the Malaysian Energy Map
Malaysia does not have one fully connected national electricity grid. Its energy infrastructure is divided among Peninsular Malaysia, Sabah and Sarawak, each with different resources, utilities and development priorities.
Peninsular Malaysia has the largest system. It supplies Kuala Lumpur, Selangor, Johor, Penang and most of the country’s major industrial areas. Tenaga Nasional Berhad plays the central role in transmission and distribution, while electricity comes from both utility-owned plants and independent power producers. Coal and natural gas provide most of the region’s power, with solar becoming more important.
Sabah operates a smaller system through Sabah Electricity. Its geography makes electricity supply more difficult. Communities, industries and towns are spread across a large area, while some rural locations remain expensive to connect. Sabah has used natural gas, oil products, hydropower and renewable projects, but it has faced tighter reserve margins and more reliability pressure than the peninsula.
Sarawak has followed a different route. Large rivers and heavy rainfall have allowed the state to build an electricity system led by hydropower. This supports both cities and energy-intensive industries, including aluminium, steel and other activities within the Sarawak Corridor of Renewable Energy.
These regional differences mean that a national energy statistic can hide important local conditions. A policy that works for Kuala Lumpur or Johor may not meet the needs of rural Sabah or the hydropower-based economy of Sarawak.
Coal Still Carries Much of Peninsular Malaysia’s Electricity Load
Coal became more important in Malaysia after the country tried to reduce its earlier dependence on natural gas for electricity. Large imported-coal plants offered stable generation and helped meet growing demand from cities, factories and commercial buildings.
Coal remains one of Malaysia’s largest sources of annual power generation. Major facilities include the Manjung complex in Perak, the Tanjung Bin plants in Johor and the Jimah facilities in Negeri Sembilan. These large stations supply steady electricity to the Peninsular Malaysia grid.
Malaysia has limited domestic coal production for its national needs, so most coal used by major power plants is imported. Indonesia has traditionally been the leading supplier because of its short shipping distance, although Malaysia can also obtain coal from other markets. This creates exposure to international prices, shipping costs and supply disruptions.
Sarawak also uses some locally sourced coal as support for its mainly hydroelectric system. However, coal plays a much smaller role there than it does in Peninsular Malaysia.
The government has stated that Malaysia will move away from coal over the long term. Current plans include ending the construction of new coal-fired power plants and retiring existing capacity as plants reach the end of their operating lives. The intended coal phaseout date is 2044.
That timetable means coal will not disappear quickly. Large plants still have commercial value, and Malaysia needs replacement capacity before they can close. Natural gas, solar, hydropower, batteries and stronger transmission networks will all be needed to prevent the coal exit from weakening grid reliability.
Natural Gas Connects Domestic Power With the Global LNG Market
Natural gas is the most flexible part of Malaysia’s conventional power system. Gas-fired plants can respond more quickly than coal stations when electricity demand rises or solar output falls. This makes gas important to both present reliability and the future expansion of renewable energy.
Malaysia produces natural gas offshore Peninsular Malaysia, Sabah and Sarawak. A large share of the resource is connected to the PETRONAS energy system, which covers production, processing, pipelines, shipping and liquefied natural gas.
Bintulu in Sarawak is the centre of Malaysia’s LNG export industry. Gas from offshore fields is processed and converted into LNG before being shipped to customers across Asia. Japan, China, South Korea and other regional markets have been important buyers. Floating LNG facilities have also allowed PETRONAS to develop fields that may be difficult to connect to land by pipeline.
Malaysia therefore has two competing uses for gas. It earns export revenue through LNG, but it also needs gas at home for electricity, industry and petrochemical production. As older domestic fields decline, maintaining both roles becomes more difficult.
Regasification terminals in Melaka and Johor allow Malaysia to bring imported LNG into the Peninsular Gas Utilisation network. This may appear unusual for an LNG-exporting country, but exports and domestic supply do not always come from the same fields or move through the same infrastructure. Imports can help balance regional shortages and seasonal demand.
Gas is expected to remain a major power source during the coal transition. The risk is that too much dependence on gas would leave consumers exposed to LNG prices and could slow emissions reductions. Malaysia must therefore decide how much new gas capacity it needs as a reliability tool rather than treating gas as an unlimited long-term solution.
Oil and PETRONAS Remain Central to the National Economy
Oil has shaped modern Malaysia since offshore production expanded during the second half of the twentieth century. The industry helped finance infrastructure, education and public services, while PETRONAS developed into a major international energy company.
Malaysia produces crude oil and condensates from offshore basins near Peninsular Malaysia, Sabah and Sarawak. Many fields are mature, making enhanced recovery, smaller discoveries and complex deepwater projects more important. Sabah has become especially significant for deepwater development, while Sarawak remains closely connected to both oil and gas production.
PETRONAS operates far beyond Malaysia. Its international upstream portfolio, LNG business, shipping operations, refineries and petrochemical investments give it a wider role than that of a normal national oil company. However, domestic production and energy security remain important because oil and gas revenues still support the Malaysian state.
The downstream sector is also substantial. Malaysia has refineries, fuel storage sites, terminals and petrochemical plants in locations such as Melaka, Kertih and Johor. The Pengerang complex in Johor is one of the largest integrated refining and petrochemical developments in the region. Its position near the Strait of Malacca gives it access to one of the world’s busiest shipping routes.
Oil use inside Malaysia is led by road transport, aviation, shipping and industry. Private vehicles remain central to daily life, particularly outside the strongest urban rail areas. Fuel prices are therefore politically and economically important.
Electric vehicles may reduce future petroleum demand, but the change will take time. Charging infrastructure, vehicle prices and the electricity used for charging will determine how quickly transport can move away from gasoline and diesel.
Grid Expansion Must Keep Up With Industry and Data Centres
Malaysia’s electricity infrastructure has supported decades of industrial growth, but demand is entering a new phase. Semiconductor production, electronics manufacturing, urban development and large data centres are increasing pressure on generation and transmission capacity.
Peninsular Malaysia recorded peak demand of more than 21,000 megawatts in 2025. Its installed capacity remained comfortably above peak demand, but reserve margin alone does not guarantee a flexible system. Plants must be available at the right time, fuel must reach them, and transmission lines must move electricity from generation areas to demand centres.
Johor has become especially important. Its connection to Singapore, available industrial land and growing data-centre market have created major new electricity needs. These facilities require power every hour of the day and often seek renewable electricity to meet corporate climate commitments. This produces demand for both reliable gas generation and new solar supply.
The grid must also become more flexible. Traditional power systems were built around large coal and gas plants that produced electricity on command. Solar output changes with cloud cover and disappears at night. Higher solar use therefore requires batteries, demand management, stronger forecasting and power plants that can adjust output quickly.
Malaysia is also part of the wider ASEAN Power Grid plan. Existing links with Thailand and Singapore show how cross-border electricity trade can support system security. Future connections could allow more renewable electricity to move between countries, although commercial rules, pricing and national energy-security concerns remain important.
Solar Is Growing Fast, While Sarawak’s Rivers Provide Scale
Malaysia’s renewable energy story has two main parts: rapid solar development across the peninsula and large-scale hydropower in Sarawak.
Solar is the main source of new renewable capacity in Peninsular Malaysia. The country has strong sunlight throughout the year, although tropical cloud and heavy rainfall can reduce output at certain times. Large-Scale Solar programmes have brought utility-size projects into the market, while the Net Energy Metering programme has supported rooftop systems for homes and businesses.
By July 2025, the government reported more than 4,200 megawatts of operational solar capacity. Solar is attractive because projects can be built faster than major thermal plants or dams. It can also be placed on industrial roofs, reservoirs, former mining land and other developed sites.
Floating solar is gaining attention because land is valuable in densely developed areas. Reservoir projects can use existing water surfaces and may share grid infrastructure with hydropower plants. The Batang Ai project in Sarawak combines 50 megawatts of floating solar with an existing hydroelectric station, allowing the two resources to support each other.
Sarawak’s hydropower system operates on a much larger scale. The 2,520-megawatt Bakun plant is Malaysia’s largest hydroelectric facility. Murum provides another 944 megawatts, while Batang Ai adds 94 megawatts. The 1,285-megawatt Baleh project is under construction and is expected to strengthen the state system further.
These dams have allowed Sarawak to attract industries that need large volumes of electricity. Hydropower also gives the grid flexible generation that can balance changes in demand. However, major reservoirs affect land, river systems and nearby communities, so future projects require careful planning and consultation.
Malaysia also has smaller renewable resources linked to its agricultural economy. Palm oil mills produce large amounts of biomass and methane-rich waste. Empty fruit bunches, palm kernel shells and biogas can be used for heat and electricity. This creates an opportunity to reduce waste while supplying power to mills or nearby communities.
Nuclear Power Has Returned to Malaysia’s Long-Term Debate
Malaysia does not operate a commercial nuclear power plant. Its only reactor is the small TRIGA PUSPATI research reactor, which is used for research, training and scientific applications rather than grid electricity.
The country considered nuclear power seriously during the early 2010s, when planners examined the possibility of building large reactors. That programme was later suspended, and nuclear electricity disappeared from the immediate national plan.
The issue has now returned. Rising power demand, coal retirement and the need for stable low-carbon electricity have led the government to reassess nuclear energy. MyPOWER Corporation has been given a central role in coordinating this work, including reviews of earlier studies and the institutional requirements for a possible programme.
This does not mean that a Malaysian nuclear power plant is already approved or under construction. The country remains in the planning and assessment stage. It would need to settle questions involving reactor technology, location, financing, regulation, radioactive waste, public acceptance and the strength of the electricity grid.
Small modular reactors are part of the discussion because they may offer smaller project sizes than traditional nuclear stations. However, their commercial costs and delivery schedules are still uncertain. Nuclear power could eventually support Malaysia’s industrial demand, but it is a longer-term option rather than an answer to immediate supply needs.
Palm Oil, Electronics and Heavy Industry Give Energy Policy an Economic Role
Malaysia’s energy choices are closely connected to the structure of its economy. The country is a major producer of electronics, electrical equipment, chemicals, petroleum products and palm oil. Each industry creates a different type of energy demand.
Electronics and semiconductor plants need highly reliable electricity. Even short power interruptions can damage production and disrupt supply chains. This makes grid quality as important as electricity volume.
Heavy industries in Sarawak use large amounts of hydropower. Aluminium smelting and other industrial processes can support economic development, but they also concentrate demand in a small number of large customers. New projects must be balanced against the needs of households and smaller businesses.
The palm oil sector creates demand for diesel, heat and electricity, but it also produces possible energy feedstocks. Biomass, biogas and biofuels can increase the value gained from agricultural waste. Malaysia also has a biodiesel industry that links palm oil markets with transport and export policy.
Oil and gas remain important sources of skilled employment, investment and government income. A rapid decline in hydrocarbons could therefore affect more than the electricity mix. Malaysia’s transition strategy aims to develop solar manufacturing, carbon management, hydrogen and other low-carbon sectors without immediately removing the economic base created by PETRONAS and related industries.
The National Energy Transition Roadmap Tries to Balance Three Pressures
Malaysia’s National Energy Transition Roadmap is built around the energy trilemma: reliability, affordability and environmental sustainability. The country wants cleaner power, but it also needs enough electricity for economic growth and prices that households and businesses can manage.
The roadmap targets a renewable share of 40 percent of installed electricity capacity by 2035 and 70 percent by 2050. It also supports energy efficiency, bioenergy, hydrogen, green transport and carbon capture, utilisation and storage. Malaysia has stated an ambition to reach net-zero greenhouse gas emissions as early as 2050.
New electricity-market programmes are intended to give businesses better access to renewable power. Corporate purchasing schemes allow companies to contract for solar electricity, while open-grid reforms could gradually reduce the dependence on a single central buyer.
These changes are especially important for multinational manufacturers and data-centre operators. Many have their own clean-energy targets and may direct investment toward countries where renewable electricity is easier to purchase.
Implementation will be more difficult than setting the targets. Malaysia must expand transmission, improve storage, manage electricity tariffs and replace coal plants without creating shortages. It must also decide how energy-transition costs will be divided among government, utilities, investors and consumers.
Malaysia’s Energy Future Depends on Connecting Its Separate Strengths
Malaysia has many of the resources needed for a more balanced energy system. It has natural gas for flexible power, strong solar potential, major hydropower in Sarawak, an experienced national energy company and a well-developed industrial base.
Its weakness is that these strengths are not always located where demand is highest. Sarawak’s hydropower cannot automatically supply factories in Johor. LNG exports do not guarantee cheap gas for Peninsular Malaysia. Solar growth does not remove the need for night-time generation, storage and transmission.
The next stage of Malaysian energy development will therefore be an infrastructure project as much as a fuel transition. Stronger grids, regional electricity trade, energy storage and clearer power-market rules will determine how much coal can be retired and how quickly renewable energy can grow.
Malaysia is unlikely to abandon oil and gas in the near future. Instead, it is trying to use its existing energy industry to finance and support a more diverse system. Whether that approach succeeds will depend on its ability to manage three very different regional power markets while meeting the demands of a rapidly changing economy.
