Billion-Dollar Gamble on Shaky Gas

Southeast Asian countries are pouring billions into new gas power plants and LNG import terminals even after a Middle East war exposed how fragile that fuel supply can be.

Story Snapshot

Southeast Asia is building over 100 gigawatts of gas-fired power plants and 70 million tons of yearly LNG import capacity.
The buildout continues despite supply risks from the ongoing war in the Middle East, which threatens shipping routes near the Strait of Hormuz.
Thailand, Vietnam, and the Philippines are each expanding LNG terminals, with Thailand aiming to nearly triple its capacity by 2029.
Analysts warn the projects could lock the region into a fuel source known for price swings and supply shocks.

A Region Doubling Down on Gas

Southeast Asia is developing more than 100 gigawatts of gas-fired power capacity and 70 million tons per year of LNG import capacity, according to data from the U.S. research group Global Energy Monitor reported by Reuters on September 23, 2026. That buildout is moving forward even though the war in the Middle East has raised fears about shipping disruptions near the Strait of Hormuz, a route much of the world’s liquefied natural gas passes through.

The total price tag for the region’s gas expansion runs close to 160 billion dollars, based on the same Global Energy Monitor analysis. Supporters say domestic gas fields could eventually soften future shocks, but new gas supplies take years to develop. That means the region’s growing reliance on imported fuel will not disappear anytime soon, even as leaders talk about diversifying energy sources.

Thailand Leads the Terminal Race

Thailand already runs the largest operational LNG import system in Southeast Asia, with about 19 million tons of yearly capacity at its Map Ta Phut and Nong Fab terminals. The country now plans a third terminal, called Map Ta Phut Phase 3, that would add another 5 million tons per year and push total capacity above 20 million tons. One developer says the new terminal will support Thailand’s growing industrial and power needs.

Some officials in Thailand want to go even further. One government leader called for expanding the country’s LNG capacity from 9 million tons to 27 million tons, describing it as a way to build “more secure, more resilient and accessible energy for everyone”. Rising electricity demand from data centers is one factor pushing that growth, according to Forbes reporting from September 2026.

Vietnam and the Philippines Expand Too

Vietnam has 14 separate LNG projects in the works that could raise its import capacity from 4 million tons to nearly 26 million tons per year. The Philippines already has six operating LNG projects providing about 10 million tons of capacity, and new developments could push that number past 24 million tons. Across the region, LNG import investments already total more than 20 billion dollars.

Warnings About Long-Term Risk

Energy researchers say the strategy carries real trade-offs. A 2024 Global Energy Monitor report found that current expansion plans could double Southeast Asia’s gas-fired power capacity and increase LNG import capacity by 80 percent. The same report warned that building out this infrastructure could lock countries into “an economically volatile and insecure fuel,” repeating patterns seen during past global gas price spikes.

Reporting from The Diplomat in April 2026 argued that Thailand “walked into its LNG trap with its eyes open,” pointing to long-term supply contracts signed well before the current Middle East conflict began. Gulf Development, a major Thai LNG player, signed a 10-year deal with Italy’s Eni and a 15-year contract with France’s Engie, locking in supply commitments that stretch well into the 2030s and 2040s.

Why the Pattern Keeps Repeating

The incentives driving this buildout are straightforward. Developers, utilities, and gas exporters profit from new terminals, pipelines, and long-term contracts, while governments can point to gas as a practical way to keep the lights on and factories running. Critics counter that overbuilding gas infrastructure risks stranded assets and deeper exposure to the same volatility the projects are supposed to guard against, a tension that has shaped ASEAN energy policy debates for years.

For everyday citizens across Southeast Asia, the stakes are less about geopolitics and more about household bills and blackouts. Whether these massive investments deliver the promised energy security, or instead saddle nations with expensive, exposed infrastructure, will likely take years to fully play out.
