Under the current draft revised power development plan (RPDP), released in 2024, Thailand aims to add 64GW of new renewable energy capacity by 2037, in order for renewables to account for 51% of domestic energy generation. The graph below shows that the contributions of gas to the country’s energy mix have increased in recent years, accounting for over two-thirds of domestic electricity generation in 2024. The report notes, however, that the current RPDP would require significant investment in new electricity generation, and leave Thailand vulnerable to foreign gas imports. Ember recommends dramatically increasing the solar and storage targets, in particular, set out in the RPDP, calling for 89% more new solar capacity and 60% more new battery capacity. Ember expects data centres alone to increase electricity demand by 10TWh by 2037, with the market to grow by a combined annual growth rate of as much as 8.5% between 2025 and 2027, while EVs are expected to account for one-fifth of the country’s electricity demand by 2037.
