BANGKOK: The Electricity Generating Authority of Thailand (EGAT) is exploring new technologies to stabilize electricity costs and reduce carbon emissions, including studying Small Modular Reactor (SMR) power plants. According to Thai News Agency, EGAT Governor Mr. Thepparat Theppitak revealed that electricity costs in Thailand are closely linked to fuel costs, particularly liquefied natural gas (LNG), and the value of the baht. The recent trend shows a stable spot price for LNG, similar to the current period, at approximately 13-14 US dollars per million BTU.
Mr. Thepparat highlighted that during the Ukraine-Russia conflict, LNG costs surged to $80 per million BTU, reflecting the volatility of global fuel prices. In response, Thailand is focusing on reducing reliance on fossil fuels to combat global warming. While renewable sources like wind and solar power are being considered, their intermittent nature poses challenges for 24-hour electricity production. To address these challenges, EGAT is studying SMR te
chnology, which promises stable power generation without carbon emissions.
The SMR model offers several advantages, including a smaller footprint, enhanced safety features, and efficient use of uranium fuel. The Linglong One power plant in Hainan Province, China, serves as a model for SMR technology, boasting a 125-megawatt capacity and a 60-year lifespan. The plant’s design includes a prefabricated reactor module, reducing system complexity and enhancing safety. EGAT is studying SMR technology from various countries to determine the best fit for Thailand and aims to educate the public and develop skilled personnel for future nuclear power projects.
Despite higher initial construction costs compared to combined cycle power plants, SMRs offer competitive electricity costs over their lifespan due to low fuel prices. EGAT views the development of SMR power plants as a game changer for Thailand, aligning with goals for energy security, environmental sustainability, and economic competitiveness. The current elec
tricity cost in Thailand is fixed at 4.18 baht per unit, with a reduced rate for vulnerable groups, reflecting government efforts to ease living costs.
EGAT’s commitment to exploring SMR technology aligns with the country’s long-term energy strategy and ongoing efforts to diversify its energy sources and enhance power system stability.
