Thailand Gas Import Crisis Threatens Electricity Supply - 2026

Thailand is facing a severe energy supply chain disruption following the closure of the Strait of Hormuz on February 28, 2026, triggered by the escalation of the US-Israel military conflict with Iran. The crisis directly threatens the country's electricity generation capacity, which relies on natural gas for approximately 57 to 68 percent of its total output. With Qatar alone accounting for nearly 43 percent of Thailand's cumulative LNG imports, the blockade of this critical maritime chokepoint has placed the kingdom's power grid under immediate and sustained pressure.

Thailand's natural gas supply comes from three main sources. Domestic production from offshore fields in the Gulf of Thailand, primarily the Erawan and Bongkot fields, represents roughly 60 percent of total gas consumption, though output has been in structural decline for years. Pipeline imports from Myanmar's Yadana and Zawtika fields contribute around 17 percent, but political instability and civil conflict in Myanmar make this supply fragile. The remaining share, approximately 29 percent as of 2024, comes from imported LNG, with volumes rising sharply each year. Qatar, Malaysia, Australia, the United States, Oman, and Brunei are the main LNG suppliers. The share of LNG in the national gas mix is projected to reach 60 percent by the mid-2030s.

The Strait of Hormuz closure has disrupted this balance at its most vulnerable point. The Ministry of Energy confirmed it was monitoring four LNG deliveries scheduled for March 2026. Two vessels had already transited the strait before the closure, while two others were still in transit. The Energy Regulatory Commission held an emergency meeting on February 25, 2026, to prepare contingency measures, including increasing pipeline gas procurement from the Gulf of Thailand and Myanmar, securing additional spot LNG from non-Middle Eastern partners, and activating swing gas provisions under existing contracts.

Thailand's electricity generation infrastructure is heavily locked into gas-fired power plants. The country operates over 11 GW of gas-fired capacity through privately owned independent power producers alone, alongside state-owned facilities run by the Electricity Generating Authority of Thailand (EGAT). Most of these plants cannot switch fuels quickly, as they were designed specifically for natural gas combustion. Alternative electricity sources remain limited in the short term. Coal and lignite contribute around 14 percent of the power mix, and the government has ordered coal-fired and hydropower plants to operate at full capacity. Hydropower imports from Laos cover roughly 15 percent of domestic demand but depend on seasonal water levels and existing transmission line capacity. Solar power, despite Thailand's enormous estimated potential of 300 GW, represented only 3.4 GW of installed capacity in 2024, and battery storage infrastructure remains minimal.

The government's emergency response has been rapid but constrained. Prime Minister Anutin Charnvirakul issued Prime Ministerial Order No. 2/2026 on March 6, suspending exports of gasoline, gasohol, diesel, Jet A-1 aviation fuel, and LPG under the 1973 Fuel Shortage Prevention Act. Diesel prices were frozen, and Shell and Caltex were pressured to roll back price increases to match the PTT retail price of 29.94 baht per litre. The Oil Fuel Fund is being used to subsidize fuel prices, burning an estimated one billion baht per day. Gas field maintenance has been postponed to maximize domestic extraction.

Civil servants have been instructed to work from home, take stairs instead of elevators, and set air conditioning to 26 to 27 degrees Celsius to reduce electricity consumption.

The economic fallout is accelerating. Brent crude surpassed 100 USD per barrel after the conflict began and peaked at 126 USD in early March 2026. Retail fuel prices in Thailand rose by 2 to 3 baht per litre cumulatively during the first weeks of March. Rayong Olefins, a unit of Siam Cement Group, suspended plant operations due to inability to obtain key petrochemical raw materials such as naphtha and propane. Unilever Thailand warned business partners of rising production costs across all segments, with price adjustments expected from April 2026 onward. Instant noodle producers reported emerging shortages of plastic packaging film, and paint manufacturer TOA was left with only 20 days of raw material stock.

The electricity tariff situation adds another layer of concern. The January to April 2026 tariff was set at 3.88 baht per kWh after a reduction driven by lower projected LNG prices at the end of 2025. However, the Hormuz crisis has reversed those assumptions. The government has stated it will seek to avoid raising electricity tariffs for the May to August 2026 billing cycle, but the Energy Regulatory Commission is reviewing the situation. According to analysis by the Ember energy think tank, every 10 percent increase in gas prices translates into a 3.5 percent increase in Thailand's electricity tariff. With LNG spot prices surging more than 45 percent since the conflict began, the pressure on power costs is substantial.

Thailand's domestic gas reserves provide limited buffer. The Erawan field, the country's largest and first commercial gas field discovered in 1972, is operated by PTTEP and currently produces around 800 million cubic feet per day. However, the field has already recovered over 72 percent of its total recoverable reserves and is projected to reach its economic limit by 2048. Across all Gulf of Thailand fields, production has been declining structurally for years, necessitating ever-larger LNG imports to fill the gap.

The broader economic outlook is deteriorating. The Federation of Thai Industries projected GDP growth of only 1.5 to 1.6 percent for 2026, the weakest in Southeast Asia, even before the Hormuz crisis. The National Economic and Social Development Council identified agriculture, manufacturing, and transport as the sectors most exposed to rising diesel costs. Marine insurance premiums have increased four to six times, and major shipping lines have rerouted vessels around the Cape of Good Hope, adding 10 to 15 days to delivery times and sharply increasing logistics costs for Thai exporters.

As of late March 2026, Thailand has approximately 95 to 100 days of total energy reserves according to government estimates, though this figure includes crude oil in transit and depends on continued access to non-Hormuz supply routes. The crisis has exposed the structural fragility of Thailand's energy model, built over decades on cheap domestic gas that is now depleting, pipeline gas from an unstable neighbor, and LNG imports routed through one of the world's most geopolitically sensitive maritime chokepoints.
