SINGAPORE, Oct 25 — A sudden reduction in piped natural gas supplies from Indonesia will account for less than 2 per cent of Singapore's total daily gas demand, the Energy Market Authority (EMA) confirmed, adding that alternative liquefied natural gas (LNG) reserves and contingency protocols will prevent any disruption to the power grid.
The market regulator was responding to announcements from Jakarta that Indonesia would scale back deliveries through two subsea pipelines feeding the island nation.
Indonesian upstream regulator SKK Migas chief Djoko Siswanto told local media that Jakarta would reduce natural gas exports to Singapore by 31 billion British thermal units per day (BBTUD) starting Oct 24.
However, the EMA clarified that data from Singapore's licensed gas importers points to a smaller curtailment of 17 BBTUD spread over 18 days, a fraction of the republic's daily consumption exceeding 1,000 BBTUD, The Straits Times reported.
“EMA understands that our importers will pursue all relevant recourse in their contracts for the gas supply disruption,” the spokesman added, emphasizing that the city-state regularly absorbs operational fluctuations between 20 and 100 BBTUD during routine maintenance cycles without incident.
Singapore generates roughly 95 per cent of its electricity from natural gas, relying on pipeline links from Malaysia and Indonesia alongside globally sourced LNG cargoes. The EMA noted that Singapore GasCo, the nation's central gas procurement entity, stands operationally primed to import supplemental shipments at short notice.
“Besides Indonesia, Singapore imports natural gas from other sources around the world.
“Power generation companies are further required to maintain sufficient fuel reserves for power generation, including diesel reserves.”
On the corporate front, Temasek-owned Gas Supply acknowledged that deliveries to local industrial clients faced “temporary reductions” from its Indonesian upstream counterpart, confirming direct discussions to cushion the operational shortfall.
“(The company) continues to engage closely with our upstream supplier to manage the situation,” the importer stated.
The pipeline curtailment follows pointed rhetoric from Indonesian Energy and Mineral Resources Minister Bahlil Lahadalia, who warned on Oct 22 that Jakarta could restrict energy shipments to nations that fail to demonstrate mutual respect.
Indonesian media have characterised the cuts, which involve 15 BBTUD from the Natuna offshore corridor and 16 BBTUD from the Jambi Merang field in Sumatra, as part of President Prabowo Subianto's drive to prioritise domestic energy security.
Sumatran gas flows directly to Gas Supply, while Natuna offshore gas feeds into Sembcorp Gas receiving terminals under long-term sales agreements scheduled to run until 2028.
Energy market economists noted that while turning to spot LNG can occasionally elevate marginal procurement costs, the modest scale of the cut means consumer electricity tariffs will absorb minimal impact.
Solar Energy Research Institute of Singapore chief executive Subodh Mhaisalkar noted that LNG acts as a critical strategic shock absorber, observing that the shortfall represents a “small portion” of daily generation needs.
Independent energy economist David Broadstock described the sudden reduction as a “surprising event” in Singapore's supply chain, noting that the timing coincides with the eve of Singapore International Energy Week and ongoing bilateral friction over transboundary haze enforcement.
“There is a question mark over whether there is a political element tied to this action, potentially making it a reaction to the haze issue.
“I wouldn’t say for sure that it is a definitive driving factor, but it certainly cannot be ruled out.”
Analysts highlighted that with LNG currently accounting for roughly 60 per cent of Singapore's gas mix, the pipeline row will likely accelerate Singapore's push toward regional electricity grid interconnectors and renewable investments.
