Ember, a United Kingdom-based energy think tank, has published a study assessing Thailand’s revised power development plan and proposing a cost-optimal pathway for the country’s energy transition. The revised plan has targeted 51 percent renewables by 2037, adding 64 GW of renewable capacity while cutting 8 GW of fossil generation. Ember’s analysis found that adding 32 GW of solar and 6 GW or 15 GWh of batteries beyond plan levels could reduce costs and strengthen energy security. The scenario has delivered projected savings of $1.8 billion, avoided 147 million tonnes of CO₂, and cut 1,815 billion cubic feet of gas. It has also lowered coal use by 2.4 million tonnes while providing $16 billion in fuel cost savings. Rising electricity demand from electric vehicles and data centres has been reliably met with solar and batteries. The study concluded that prioritising solar and storage policies and improving demand forecasting were essential steps for Thailand.
