Thailand has accelerated its net-zero emissions target by 15 years to 2050, triggering a major overhaul of national energy policy. The power sector, responsible for 48.1 million tonnes of COâ‚‚ emissions in early 2024, faces the most significant transformation.
Key Takeaways
- Thailand’s new 2050 net-zero target requires replacing the 2024 Power Development Plan
- Renewable energy must reach 77% of the power mix by 2050, up from 51% under previous targets
- Small Modular Reactors (SMRs) are now central to Thailand’s energy security strategy
- Private sector investment in nuclear technology is gaining momentum
Ambitious Energy Transition
The Anutin Charnvirakul government’s decision to move the net-zero deadline from 2065 to 2050 demands rapid changes across Thailand’s energy landscape. The Energy Ministry is drafting a new Power Development Plan that prioritizes shifting from fossil fuels, scaling renewables, and introducing nuclear power.
Power generation remains Thailand’s largest carbon source, emitting 48.1 million tonnes of COâ‚‚ in H1 2024. Transport followed with 41.5 million tonnes, while manufacturing contributed 25.6 million tonnes.
Renewable Energy Challenges
Meeting the 2050 deadline requires increasing renewable share to 77%, according to BloombergNEF. However, solar and wind’s intermittent nature presents technical hurdles.
“Achieving net zero by 2050 is not just about building more solar farms, but rather a resilient system that can deliver reliable power around the clock,” energy officials stated.
Battery storage and pumped hydro remain costly, while natural gas plants will serve as transitional backups.
Nuclear Power Integration
The new PDP marks a significant shift by including Small Modular Reactors (SMRs). These compact 300MW units offer stable, zero-carbon power.
“Public acceptance is crucial,” said Energy Minister Auttapol Rerkpiboon, addressing safety concerns.
Narin Phoawanich, Egat’s new governor, emphasized SMRs “strike the perfect balance between reliability, affordability and environmental responsibility.”
Private Sector Momentum
Global Power Synergy Plc (GPSC), PTT Group’s power arm, is investing in SMR development and seeking international partnerships.
“SMRs are essential to Thailand’s future competitiveness,” said GPSC President Sirimet Leepagorn, noting data centers and electronics industries require stable, carbon-free electricity.
GPSC expects to finalize joint ventures next year, positioning Thailand for nuclear energy leadership while balancing public sentiment, costs, and energy security.
