Singapore Energy Transition | Gas, Grid Security and the Shift to Lower-Carbon Power

Singapore’s energy transition is unusually difficult because almost every major national system depends on electricity while the country has very limited domestic renewable resources.

Homes need power. Trains need power. Water treatment and pumping need power. Hospitals, ports, airports, factories, data centres and digital government need power. Decarbonising electricity is therefore not simply an environmental project. It is an attempt to change one of the country’s most upstream systems while keeping everything downstream alive.

At a glance

• About 95% of Singapore’s electricity is still generated using imported natural gas.
• Natural gas remains a transition fuel because it supports dependable generation while lower-carbon alternatives scale.
• Singapore is diversifying gas procurement through Singapore GasCo and developing additional LNG infrastructure.
• Low-carbon electricity imports are becoming a major new route; Singapore now targets around 6 GW of imports by 2035.
• The transition must reduce carbon and concentration risk without withdrawing reliable capacity faster than substitutes become dependable.

Why imported gas became so important

Natural gas became the dominant fuel for Singapore’s electricity system because it is cleaner than the fuel oil it largely displaced, can support efficient combined-cycle generation and provides dispatchable power when demand requires it.

That delivered real benefits. It also concentrated dependence. If most electricity comes from one broad fuel class and that fuel is imported, disruptions in global gas markets can move quickly into national energy costs.

DEPENDABLE GAS POWER
→ HIGH ELECTRICITY RELIABILITY
→ CONCENTRATED IMPORT DEPENDENCE
→ PRICE + SUPPLY EXPOSURE

2026 showed the exposure clearly

In 2026, conflict in the Middle East disrupted global fuel supply and pushed natural-gas prices higher. EMA explicitly warned that Singapore’s dependence on imported gas would feed into higher electricity and town-gas tariffs. The July–September 2026 regulated tariffs reflected these elevated fuel costs.

This is an important reminder that a reliable domestic grid can still be exposed to events thousands of kilometres away. The generators may be in Singapore; the fuel system is global.

Energy security is more than having enough power plants

Installed generation capacity does not guarantee usable electricity. Fuel must arrive. Contracts must hold. Gas infrastructure must remain available. Grid equipment must function. Reserve capacity must exist for faults and maintenance.

Singapore therefore uses multiple buffers: gas-storage and LNG arrangements, alternative fuel requirements for generators, diversified procurement and longer-term infrastructure planning. The purpose is not to eliminate dependence—Singapore cannot—but to prevent one supply disruption from becoming a national blackout.

GasCo changes how fuel risk is managed

Singapore GasCo was established in 2025 to centralise procurement and supply of natural gas to the power sector. By 2026 it was fully operational. The logic is straightforward: aggregating demand can improve bargaining power, support longer-term contracting and diversify sources more deliberately than leaving every generator to solve the same problem independently.

This does not make gas risk disappear. It changes the institutional capacity for managing it.

A second LNG terminal adds another physical route

Singapore is also developing a second LNG terminal using a floating storage and regasification unit connected to onshore infrastructure. EMA expects it around 2030 and says it will increase LNG capacity significantly.

This is classic resilience architecture: if one receiving route is constrained, another can provide capacity. But redundancy only helps if the alternative route has fuel, contracts, physical access and enough spare throughput when it is needed.

Solar helps, but land is a hard constraint

Singapore has expanded solar deployment because sunlight is one of the few domestic renewable resources available at scale. Yet land scarcity limits how much conventional solar can be installed, and solar generation varies with weather and time of day.

That means solar is valuable but cannot simply replace dispatchable generation on its own. Storage, grid flexibility and other sources have to work around its variability.

Regional electricity imports create a new corridor

The largest structural change may be the move toward importing low-carbon electricity from the region. Singapore now targets around 6 gigawatts of low-carbon electricity imports by 2035, roughly one-third of projected electricity demand then.

In August 2026, EMA granted conditional approvals for another 900 megawatts of electricity trade from Peninsular Malaysia, adding to a broader portfolio of projects involving Australia, Cambodia, Indonesia, Malaysia and Vietnam.

This can lower carbon intensity and diversify the generation mix. It also creates a new kind of dependency: cross-border interconnectors, foreign generation assets, regional regulation, financing, weather conditions and geopolitical relationships become part of Singapore’s power corridor.

LOW-CARBON IMPORT
→ LOWER DOMESTIC FUEL BURN
+ NEW REGIONAL DEPENDENCIES
→ DIVERSIFICATION IF ROUTES ARE TRULY INDEPENDENT

The transition cannot be judged by carbon alone

A lower-carbon power system that fails frequently would not be a successful transition. Neither would a perfectly reliable system that locks itself permanently into high emissions if viable alternatives become available.

Singapore therefore has to optimise several variables at once: reliability, affordability, carbon intensity, fuel diversity, system flexibility and long-term technological readiness.

AI and data centres increase the load

The energy transition is happening while demand is changing. Artificial intelligence, data centres, advanced manufacturing and electrification can increase power requirements. A transition plan that assumes static demand can therefore become obsolete even if every project arrives on schedule.

This makes efficiency strategically important. Every unit of energy avoided through better buildings, equipment or computing reduces the amount of new supply the system has to secure.

The human receipt is the electricity bill and the light switch

Energy policy can sound abstract until it reaches a household. Fuel-market volatility appears as electricity prices. Reliability appears as whether the lights stay on. Decarbonisation costs and investments eventually have to be financed somewhere in the system.

Businesses experience the same system differently. Energy-intensive industries care about price predictability and capacity. Data centres care about both reliability and access to lower-carbon power. Lower-income households have less room to absorb price shocks.

A national energy strategy therefore succeeds only if the transition remains economically and physically usable for its receivers.

What should be preserved?

The function to preserve is not natural gas. Gas is a vessel currently performing an important job. The deeper function is dependable, affordable electricity with acceptable environmental cost.

That distinction prevents two opposite mistakes: keeping yesterday’s fuel forever because it works now, or abandoning dependable capacity before the replacement system can carry the load.

Evidence and limits

EMA states that imported natural gas produces about 95% of Singapore’s electricity. Singapore GasCo is operational as part of the effort to diversify and strengthen gas supply. Singapore now targets around 6 GW of low-carbon electricity imports by 2035 and has granted approvals or licences across multiple regional projects. These are active transition programmes, not guarantees that every project will arrive on its proposed timetable or at its expected cost.
