How Gas Arrives in Singapore | Pipelines, LNG and Fuel Security

Singapore does not produce the natural gas that powers most of its electricity system.

It imports the fuel, converts it into a form the power stations can use, moves it through a regulated gas network and surrounds the supply chain with several buffers so one disruption does not automatically become an electricity shortage.

Natural gas remains the anchor fuel of Singapore’s power system. EMA stated when Singapore GasCo was established that natural gas accounted for around 95% of electricity generation, and the Government continues to describe gas as central to the medium-term energy mix while solar, imports and other low-carbon pathways expand.

The fuel arrives through two broad routes: pipeline gas from the region and liquefied natural gas carried by ship. LNG is unloaded at Singapore’s terminal, stored as a cryogenic liquid, warmed back into gas and sent into the domestic pipeline network.

The operating chain is: regional pipeline or LNG cargo → import/terminal interface → storage and regasification where applicable → gas transmission network → power station → gas turbine/combined-cycle generation → national electricity grid.

1. Singapore’s gas system began with pipelines

In the early 2000s, Singapore relied heavily on piped natural gas imported from Indonesia and Malaysia for power generation.

Pipeline gas remains part of the supply portfolio today, although the exact commercial mix can change over time.

The advantage is direct delivery from regional gas fields through connected infrastructure. The vulnerability is equally obvious: the fuel is tied to particular upstream fields, pipelines and cross-border supply arrangements.

2. LNG separated Singapore from one pipeline geography

Liquefied natural gas changes the logistics problem.

Natural gas is cooled until it becomes a dense liquid suitable for marine transport. Instead of being connected only to a fixed pipeline route, Singapore can buy LNG cargoes from a wider set of global suppliers and receive them by ship.

Singapore began importing LNG in 2013 when the Singapore LNG Terminal on Jurong Island commenced operations.

3. The Jurong Island terminal is the physical conversion point

The SLNG terminal receives LNG carriers, unloads LNG into insulated storage tanks and later regasifies the liquid for delivery into the gas pipeline network.

EMA currently describes the terminal as having two jetties, four storage tanks and peak send-out capability equivalent to about 11 million tonnes per annum.

The terminal therefore performs three different jobs: marine import terminal, strategic storage facility and gas-conversion plant.

4. LNG storage creates time between arrival and use

A pipeline delivers gas continuously while it is flowing.

An LNG cargo can be received in a large batch and stored until the power system needs the gas.

That storage function gives operators more flexibility to separate ship-arrival timing from hourly electricity demand.

The tank is therefore not simply waiting space. It is part of Singapore’s fuel-security buffer.

5. Regasification turns LNG back into pipeline gas

Power stations do not ordinarily burn the LNG as a cryogenic liquid.

The terminal warms the LNG so it returns to gaseous form, then sends the gas into the national gas pipeline system at the required operating conditions.

From that point onward, pipeline gas and regasified LNG can serve the same downstream gas infrastructure even though they arrived in Singapore through different routes.

6. PowerGas owns the regulated gas transport network

EMA identifies PowerGas as Singapore’s Gas Transporter Licensee.

PowerGas owns and manages the gas pipeline network and is required to provide open and non-discriminatory access to the network under the regulatory framework.

SP PowerGrid acts as the Gas Transport Agent on behalf of PowerGas.

The import market and the physical transport network are therefore separated institutionally: several gas suppliers can use one regulated pipeline system rather than each building a private national network.

7. The power stations convert gas into electricity through combined-cycle plants

Modern gas-fired generation in Singapore relies heavily on combined-cycle gas turbine technology.

A gas turbine burns natural gas to generate power. Hot exhaust that would otherwise be wasted is then used to produce steam for a steam turbine, extracting additional electricity from the same fuel.

The gas system therefore ends where the electricity system begins.

8. Singapore GasCo centralises procurement for the power sector

Singapore GasCo was established in 2025 as a fully Government-owned entity to centralise procurement and supply of natural gas for power generation.

EMA’s 2026 energy-transition update states that GasCo has completed its initial setup and is fully operational.

The objective is to aggregate demand across generation companies so Singapore can negotiate a more diversified portfolio of sources, contract durations and pricing structures instead of leaving every generator to optimise only its own narrower position.

9. Diversification is a portfolio problem

Energy security does not require predicting which supplier will fail next.

It requires avoiding a system in which one failure is large enough to become catastrophic.

GasCo can diversify among LNG sources, contract durations and pricing indices while pipeline imports remain another supply route.

The fuel portfolio therefore works like risk management: no single commercial source should carry more importance than the system can tolerate.

10. The Standby LNG Facility is a buffer for disruption

EMA maintains a Standby LNG Facility arrangement that generation companies can draw upon when normal gas supplies are disrupted, subject to the prevailing framework.

The standby facility is not the ordinary commercial fuel route for every day.

Its value appears when another route fails: a buffer is economically quiet during normal conditions and operationally important during abnormal ones.

11. Generation companies must maintain gas security arrangements

EMA’s current fuel-security guidance states that generation companies are required to maintain sufficient gas for power generation based on the capacity of their generation units.

The requirement reduces the risk that a power station remains mechanically available but has insufficient fuel to perform its electricity-market obligations.

12. Diesel provides an alternate fuel for selected power plants

EMA also requires generation companies to maintain diesel reserves as an alternative to natural gas where the generating plant is designed for dual-fuel operation.

Switching to diesel is not the preferred everyday mode. It is typically more expensive and less attractive environmentally.

Its security value comes from independence: a plant that can operate temporarily on another fuel is less exposed to one gas-supply failure.

13. The current LNG terminal can cover present gas demand if required

SLNG states that its existing Jurong Island terminal currently supplies about half of Singapore’s natural gas for electricity, with the balance coming from pipeline gas under prevailing supply conditions.

SLNG also states that the terminal has sufficient capacity to meet Singapore’s present natural-gas demand if required.

That capability is strategically important because it means pipeline disruption does not automatically remove half the nation’s gas-delivery capability from an infrastructure standpoint.

14. A second LNG terminal is now under construction

Singapore is developing a second LNG terminal at Jurong Port using a Floating Storage and Regasification Unit linked to onshore connecting infrastructure.

Construction activity progressed materially in 2026: SLNG marked the start of onshore connecting infrastructure works in March and the FSRU keel-laying milestone in May.

EMA expects the second terminal to be ready by around 2030 and to increase Singapore’s LNG capacity by roughly 50%.

15. The second terminal is capacity and redundancy at the same time

Future electricity demand is expected to rise, so Singapore needs more gas-handling capacity during the transition.

A second terminal also reduces dependence on one physical LNG site.

That is a different type of diversification from buying LNG from more suppliers. Supplier diversification protects the commercial portfolio. Terminal diversification protects the physical import architecture.

16. Gas security still cannot become full energy independence

Singapore remains dependent on imported energy.

Gas storage, LNG diversification, second-terminal capacity and diesel reserves reduce vulnerability, but they cannot manufacture unlimited fuel during a prolonged global shortage.

EMA explicitly notes that severe and prolonged disruption to global fuel supplies could still affect domestic electricity supply.

Resilience therefore means absorbing credible shocks better—not claiming that imports no longer matter.

17. A worked example: one pipeline supply is interrupted

Imagine part of Singapore’s normal pipeline gas supply becomes unavailable.

GasCo and industry participants adjust the supply portfolio. LNG already in storage can continue being regasified and sent through the pipeline network. Additional LNG cargoes can be procured where commercial and shipping conditions permit. Generation companies can draw on standby gas arrangements and maintain alternate-fuel readiness according to the prevailing security framework.

The interruption is serious. The system is designed so it does not begin from zero alternatives.

18. Common misconceptions

Misconception: Singapore’s power stations receive all gas through one pipeline.
No. Singapore uses both regional pipeline gas and LNG imported by ship and regasified locally.

Misconception: LNG is a different fuel from natural gas.
No. LNG is natural gas cooled into liquid form for transport and later regasified.

Misconception: GasCo owns every pipeline and terminal.
No. GasCo centralises procurement for power-sector gas; separate licensed entities own and operate terminal and gas-transport infrastructure.

Misconception: A second LNG terminal means the first terminal is inadequate today.
No. the second terminal is being built for future demand growth and greater physical resilience.

Misconception: Fuel reserves make Singapore immune to global energy shocks.
No. reserves buy time and optionality; Singapore remains an imported-energy system.

19. The deeper idea: energy security is built from non-identical backups

A perfect backup is not another copy of the same vulnerable route.

Pipeline gas and LNG arrive differently. LNG storage separates ship arrival from hourly use. GasCo diversifies contracts. The Standby LNG Facility provides emergency optionality. Dual-fuel plants preserve an alternate fuel path. A second LNG terminal creates another physical import node.

Each layer protects against a different failure.

Singapore’s gas system becomes resilient not because one component is unbreakable, but because a break in one component does not automatically remove every other route at the same time.
