KUALA LUMPUR – Malaysia is making a decisive shift in its future energy mix, balancing economic development with environmental sustainability. In the past, the country relied almost solely on coal as the fuel for power generation but is now investing around RM30 billion in a fuel mix that includes solar – as well as natural gas. This is especially important to the third-largest economy in Southeast Asia as outlined in the National Energy Transition Roadmap (NETR).
Coal has been fundamental to energy security for Malaysia over decades, as it has been a cheap and dependable source of baseload generation. However, the environmental cost is now unaffordable. The power sector is a significant source of the country's greenhouse gas emissions, and global pressure for decarbonization is mounting. To that end, the Malaysian government has set itself ambitious targets; including a commitment to achieving net-zero greenhouse gas emissions by 2050 and to increase the renewable energy share of installed capacity to 70% by 2050
The new energy strategy is not just one silver bullet but pragmatic dual-track pathway. On one front, the country is unlocking the opportunity of solar power. On another, it is positioning natural gas as a critical "transition fuel" that maintains grid stability and reliability during the transition.
The Solar Surge
Being located on the equator means Malaysia has very strong and consistent solar irradiation, making solar the most promising renewable resource. The government is promoting large-scale solar (LSS) projects as part of its competitive bidding programs, and prices have come down significantly, resulting in sizable domestic and foreign investments.
In addition to the large-scale solar farms, the government is also strongly advocating "distributed generation." For example, the Net Energy Metering (NEM) program allows residential, commercial, and industrial users to install solar panels on their rooftops and offset their electricity bills by selling the excess electricity they generate back to the grid. This will reduce some of the load on the national grid and will democratize energy provision.
"The economics of solar have become irresistible," explained Dr. Aishah Rahman, an energy analyst at a local think tank. "The levelized costs of energy from solar are now competitive, and in many cases lower than fossil fuel energy alternatives. We are seeing a rush from corporations, especially multinationals that have their own sustainability targets, to deploy captive solar systems to power their operations."
The aspiration encompasses large-scale developments, including developing large solar parks in Sarawak (which has considerable hydroelectric power), and even floating solar farms in reservoirs and old mining ponds to maximize the land usage in a crowded country.
The Role of Natural Gas as a Bridge
Although solar energy is a renewable energy source of the future, its intermittent nature-reliant on sunlight and weather-creates difficulties for grid stability. That's where natural gas comes in. Malaysia is one of the world's largest liquefied natural gas (LNG) exporters, and it too, intends to direct more of this fuel to domestic use.
Natural gas is promoted as the best partner for renewables. Unlike coal, gas fired power plants can ramp up or down relatively quickly and therefore will be good options for backup power when the sun is not shining. This flexibility is important for integrating a large amount of variable solar power into the electric grid without sacrificing reliability.
"To rule out natural gas makes light of the practicalities of energy transition," said Energy Minister, Yang Berhormat Tengku Muhammad Taufik, continuing: "It is the cleanest option among fossil fuels, and provides the grid flexibility we require as we build our renewable capacity, and, also importantly, our energy storage systems. Natural gas is the bridge to a greener future, without leaving the nation in the dark."
The government's position is to continue developing domestic gas fields and ensure adequate regasification capacity to meet the added domestic demand, while providing a hedge against volatility in the global energy market. This will provide an element of energy independence.
Challenges and the Road Ahead
Although a clear strategy exists, there are still hurdles to overcome on this path. The transition will require significant investments in modernizing the grid. The existing grid was established to support centralized coal and gas plants but will need to be upgraded to manage new types of power flows and increased complexity.
In addition, even though natural gas is cleaner than coal, it is still a fossil fuel that emits carbon. Critics suggest that overinvestment in gas infrastructure could result in a "lock-in" effect, which will slow full deployment of zero-carbon energy. The government responds that carbon capture, utilization, and storage technologies could be utilised later to reduce emissions.
The human capital issue is more vexing. As the coal industry winds down, a just transition for impacted workers is needed, as well as new jobs in solar installation, grid management, or renewable energy engineering to replace those workers.
International partners and global financial institutions are paying attention. If Malaysia succeeds, it will provide a model for other developing economies in the region that are resource rich, but need to balance development and decarbonization.
The country's bet on a mix of solar and gas is a calculated one. It understands that the path to a net-zero future is a long haul, not a short sprint. By utilizing its natural advantages, and taking a pragmatic and phased approach, it plans on ensuring energy security, economic growth, and a place for its economy in a low-carbon world. The world is waiting to see if this bet pays off.
