Southeast Asia’s LNG expansion may lock regional supply chains Into structural risk
20 Feb 20268 min read
Summary
- Energy demand across Southeast Asia is rising quickly. Governments are turning to liquefied natural gas as a bridging solution to prevent power shortages and support industrial growth.
- But LNG prices are tied to global markets. Recent energy shocks showed how quickly costs can spike when supply is redirected or demand surges elsewhere. For economies that rely on imported gas, volatility does not stay contained within the energy sector.
- As ports electrify and cold chains expand, electricity stability becomes a supply chain issue. The question is whether expanding LNG infrastructure reduces risk, or locks it in.
This framing is increasingly relevant in Southeast Asia (SEA), where energy strategy is becoming a huge factor of supply chain resilience. According to the 7th ASEAN Energy Outlook, energy consumption in SEA is projected to nearly triple by 2050 from 2020 levels under the Baseline Scenario, reaching 1,281.7 million tonnes by 2050.
International management firm, Arthur D. Little, notes three reasons for this surge. First, increased economic activity where the pace of renewable energy penetration is not enough; The inadequate transmission and distribution status of power grids, especially in remote locations; Lastly, the policy emphasis on electric vehicles particularly Indonesia, Malaysia, and Singapore.
To prevent power shortages that could disrupt growth, governments are turning to Liquefied Natural Gas (LNG) as one of the bridging solutions.
The Philippines illustrates this shift clearly. With the Malampaya gas field expected to be depleted by 2027, the country has committed to large-scale LNG imports since 2023 to stabilize its power system. Vietnam followed a similar path, initiating LNG imports in the same year as rising electricity demand outpaced domestic supply. Across the region, traditional LNG exporters are also reprioritizing. Thailand, Malaysia, and Indonesia, long-standing suppliers, are starting to redirect LNG to meet domestic power demand.

LNG’s unclear potential
LNG has been regarded across SEA as a means of strengthening energy security and supporting economic growth, as seen in ramped up investments. Yet recent experience across the region suggests that LNG has delivered uneven outcomes when measured against key indicators of security such as affordability, reliability of supply, and system resilience.
For example, the 2021–2022 global energy crisis was a critical stress test for LNG-dependent systems in SEA. As European demand surged following the Russia-Ukraine conflict, LNG cargoes were redirected to Europe which tightened availability and drove up prices across Asia. Because LNG prices in Asia are now highly correlated with European benchmarks, Southeast Asian importers found themselves competing in a global market over which they have limited control.
Thailand offers a clear illustration. As domestic and pipeline gas supplies declined, LNG imports rose by 28% in 2022 to meet power demand. According to the Institute for Energy Economics and Financial Analysis, higher LNG costs contributed to a doubling of domestic gas prices and record electricity tariffs. To contain the economic impact, the Thai government absorbed substantial fiscal costs, including approximately USD 2.2 billion in electricity subsidies in early 2023.
Singapore experienced similar pressures. Between August 2021 and August 2022, LNG contract prices increased by around 50% year-on-year, while spot LNG prices surged by more than 200%. Electricity tariffs rose sharply, prompting a USD 1.5 billion government support package to offset higher household energy costs.
Beyond price shocks, demand volatility has further complicated LNG’s role in SEA’s energy strategy. LNG demand across several ASEAN markets has softened as high prices, economic headwinds, and rapid growth in renewable capacity reduce reliance on gas-fired power.
In Thailand, LNG imports are expected to decline 13% as slower economic growth and a surge in solar generation curb gas demand. In the Philippines, the Department of Energy cancelled a 1.1 gigawatt LNG-to-power project citing low use of import terminals and gas turbine constraints in November 2025. While Vietnam’s LNG-to-power projects continue to face commissioning delays and contractual challenges which have weighed heavily on investors.

“Without guaranteed cash flow, it’s nearly impossible to raise capital, especially with LNG price volatility. Investing in these projects feels like entering a trap,” says Pham Huu Hien, Director of Binh Phuoc Energy Investment JSC.
These patterns point to a structural issue. LNG demand in Southeast Asia is neither stable nor guaranteed. It fluctuates in response to global price movements, policy adjustments, and the availability of cheaper domestic alternatives. As a result, LNG infrastructure investments, which require decades of high utilization to remain viable, face growing risks of underperformance and underutilization.
When LNG becomes a supply chain risk
Energy price shocks do not affect all sectors equally, but in SEA they consistently hit energy-intensive supply chain industries first and hardest. A regional study from the Foreign Trade University in Vietnam showed that global energy price shocks transmit rapidly into SEA economies through manufacturing, transport, and electricity generation.
These sectors form the backbone of regional and global supply chains. When energy prices surge, the result is reduced industrial output, disrupted logistics flows, and weaker macroeconomic performance. According to the study, real GDP contractions can go up to 3.8% in countries like Thailand and Malaysia.
Crucially, the study finds that while agriculture and food production are relatively insulated due to lower energy intensity, manufacturing, transport, and electricity generation suffer output declines of up to 17% after energy price shocks. This capacity remains constrained by SEA’s continued reliance on fossil fuels, particularly imported LNG.
This matters for supply chains because LNG-linked power systems convert global fuel volatility into domestic electricity volatility. Even when power remains available, it becomes less predictable and more expensive. These are conditions which affect supply chain performance.
Cold storage illustrates this exposure clearly. Across Asia-Pacific in general, electricity accounts for roughly 25% to 30% of operating expenses in cold storage facilities. This reflects the region’s tropical climate, expanding food distribution networks, and the growth of pharmaceutical and e-commerce supply chains.
Ports and container terminals are becoming similarly exposed as they electrify operations. SEA’s major trade gateways are slowly using electric cranes, yard vehicles, and berth infrastructure. Singapore’s PSA Tuas has deployed battery-powered automated guided vehicles (AGV) and plans to operate around 200 electric AGVs as the terminal scales. In Malaysia, the Port of Tanjung Pelepas has committed to electrifying yard operations with signed agreements to procure electric prime movers to make up the majority of its fleet. Similar transitions are emerging at Vietnam’s major ports, including Cat Lai and Cai Mep–Thi Vai.
As ports electrify, logistics costs become structurally tied to electricity tariffs and grid stability. In LNG-dependent systems, this means that global gas price volatility feeds directly into port handling costs, cold chain reliability, and downstream logistics pricing.
This is where infrastructure deadlock takes hold. LNG terminals, regasification facilities, and gas-fired power plants require high utilization to recover capital costs. Once built, they anchor electricity systems to imported fuel and long-term contracts. Even as renewable power becomes cheaper, utilities face pressure to keep plants running to justify investments.
For example, The Philippines plans to increase LNG imports by over 500 percent between 2025 and 2029, with total infrastructure investment reaching around USD 5.4 billion. However, according to Giancarlo Enriquez, energy program lead at The Climate Reality Project Philippines, this locks the country into a fuel that is neither “cheaper or cleaner.”

“While limited LNG imports may be necessary to support the existing fleet of gas plants, expanding LNG infrastructure on a large scale, which may end up as stranded assets, risks locking the Philippines into a costly, volatile, and fossil-dependent energy future,” Enriquez noted in an interview.
Japanese investment reinforces this lock-in. Japanese utilities and financial institutions, including Tokyo Gas, Osaka Gas, and public lenders such as the Japan Bank for International Cooperation, have financed and taken equity stakes in LNG infrastructure across Southeast Asia.
According to Walter James, Principal Consultant at Power Japan Consulting, these investments are driven by structural incentives. Following the Fukushima disaster, Japanese utilities secured large volumes of LNG under long-term contracts. As domestic demand in Japan declines due to nuclear restarts and renewable expansion, these firms remain overcontracted and seek stable overseas demand to absorb surplus supply.
While Japan argues that its LNG investments in Asia support its economic growth, James argues that Japan’s LNG pivot to Southeast Asia “does not genuinely promote the region’s decarbonisation or energy security,” as increased LNG imports expose the region to global price volatility and crowd out renewable energy deployment.
The result is SEA’s mismatched energy and development strategy. The region is electrifying its supply chains to improve efficiency, sustainability, and competitiveness, while simultaneously anchoring those systems to energy infrastructure that amplifies volatility and limits flexibility.

Energy choices as supply chain choices
Electrification is necessary for efficiency, decarbonisation, and modernization. The risk lies in what electrified supply chains are plugged into. If the backbone remains dependent on imported LNG and rigid infrastructure, electrification amplifies volatility instead of reducing it.
The strategic question for SEA, then, is not whether LNG can fill short-term gaps. It is whether expanding LNG infrastructure affects the region’s ability to build flexible, cost-stable supply chains tomorrow. In a global economy shaped by geopolitical shocks, climate disruption, and rapid tech changes, energy systems that limit adaptability may become a liability rather than a safeguard.
“Energy also travels through its own supply chains,” Wolfgang Lehmacher notes as the energy systems that SEA builds today will shape how resilient its supply chains become, or how deeply they remain exposed to volatility long after the transition window has closed.
