Thailand Unveils 5 GW Rooftop Solar Initiative to Curb LNG Reliance
Thailand has announced an ambitious plan to deploy 5 GW of rooftop solar capacity across one million households within the next year, marking a significant step in the nation's strategy to reduce dependence on volatile natural gas and LNG markets.
The program will be backed by a 200 billion baht (approximately US$6.01 billion) emergency energy transition fund. Under the scheme, households will be eligible for subsidies of up to 50,000 baht per installation, supplemented by low-interest financing options to accelerate residential solar adoption.
Currently, solar accounts for roughly 10% of Thailand's electricity generation mix, while natural gas dominates at over 60%. With more than a quarter of the country's gas supply sourced from imports, domestic energy prices remain highly susceptible to international LNG market fluctuations.
Industry analysts project that this new push will more than double Thailand's small-scale solar capacity from approximately 3.6 GW recorded at the end of 2025.
The rooftop initiative is set to be integrated into Thailand's long-term power development framework, reinforcing the government's commitment to strengthening energy security and accelerating the renewable energy transition.
This development underscores the increasing momentum of distributed solar generation across Southeast Asia, as regional economies seek practical pathways to reduce fossil fuel dependency and enhance energy resilience.
