That advantage is weakening as production from domestic fields declines and imported liquefied natural gas (LNG) fills the gap. Shipping rates, exchange-rate changes, and geopolitical disruptions can raise the delivered cost even when Thai electricity demand stays steady. The high cost of Thailand’s LNG import plans includes these wider environmental pressures, along with pollution risks near terminals and industrial facilities. The Opportunity Cost of Staying Locked Into GasMoney committed to imported fuel, LNG terminals, pipelines, and new gas plants cannot be spent twice. Recent estimates place gas-fired generation at roughly 53% to 68% of Thailand’s electricity, depending on the year and measurement method.
