Small immediate reduction raises bigger questions over Singapore’s gas dependence after 2028.
Indonesia’s recent reduction in pipeline gas exports to Singapore is unlikely to cause immediate disruption to the city-state’s electricity supply, but it has renewed questions about long-term energy security as neighboring countries prioritize growing domestic demand.
Indonesia Redirects Gas for Domestic Power
Indonesia began reducing natural gas exports to Singapore on October 24, redirecting 31 million standard cubic feet per day from Natuna and Sumatra to meet domestic electricity needs. Indonesia’s upstream oil and gas regulator, SKK Migas, said the move was intended to safeguard domestic gas supplies for power generation. The reduction has also raised questions about existing export commitments, with Singapore emphasizing that commercial gas supply agreements should be honored.
Immediate Impact on Singapore Remains Limited
Singapore’s Energy Market Authority said the reduction represents less than 2% of the country’s total daily gas demand. Natural gas supplies about 95% of Singapore’s electricity, but authorities and energy analysts said the current cut should remain manageable unless reductions deepen or additional production disruptions occur. Short-term electricity prices are also expected to be influenced more by global gas prices than by the present reduction alone.
Indonesia Faces Rising Domestic Gas Demand
Analysts cited by CNA said Indonesia’s growing economy, electricity consumption, fertilizer industry, and expansion of data centers are increasing competition for domestic natural gas supplies. SKK Migas vice-president Rayendra Sidik said multiple sectors are demanding more gas simultaneously, making long-term planning increasingly difficult. Analysts also noted that infrastructure capacity limits how much exported gas can simply be redirected to Indonesian consumers.
Singapore Has Built LNG Alternatives
Singapore has sought to reduce its dependence on pipeline supplies by expanding liquefied natural gas imports. In 2025, piped gas represented 43% of Singapore’s gas imports, while LNG accounted for 57%. Prime Minister Lawrence Wong said Singapore’s LNG infrastructure allows the country to purchase gas from different international suppliers, while also emphasizing that parties to existing commercial supply agreements are expected to honor their commitments.
Post-2028 Supply Emerges as Bigger Test
Analysts said Singapore’s more significant energy-security challenge could emerge after 2028, when existing Indonesian gas export contracts begin expiring. To reduce its dependence on individual suppliers, Singapore is expanding its LNG options and pursuing low-carbon electricity imports from countries including Indonesia, Malaysia, Cambodia, Vietnam, and Australia. Several of these electricity projects have received conditional approvals or licenses but are not yet operational. Although the current gas reduction is relatively small, it highlights the importance of securing reliable energy supplies over the longer term.
Indonesia’s gas reduction reflects Jakarta’s need to balance export commitments with growing domestic demand, particularly in areas such as Batam, Bintan, and Sumatra. For Indonesians, retaining more gas could support domestic electricity requirements, although infrastructure and commercial considerations remain important. For Singaporeans, the immediate disruption is limited, but the episode reinforces the importance of LNG diversification, regional electricity projects, and reliable supply arrangements as existing gas contracts approach expiration.
