Thailand's Gas-Powered Grid Faces Volatile Future Amid LNG Dependence

Thailand's power system is heavily reliant on gas-fired plants, which supplied around two-thirds of the country's electricity in 2024. However, this dependence on gas has its drawbacks. The cost of imported liquefied natural gas (LNG) can be volatile and exposed to global price spikes, making it challenging for Thailand to maintain a stable power system.

The country's reliance on LNG has increased significantly over the years, with imports accounting for approximately 29% of Thailand's gas consumption in 2024. This shift from domestic production to imported LNG has led to higher fuel costs and placed upward pressure on electricity bills. The long-term contracts, terminals, and new gas plants may improve short-term security but will extend import costs for decades.

The energy sector is interconnected, and a change in one area can have far-reaching consequences. Thailand's dependence on gas highlights the importance of balancing energy security, affordability, and environmental concerns. Examining the impact of declining domestic supply and rising LNG imports can help policymakers develop strategies to address these challenges.
