Thailand is poised to significantly ramp up investment in new energy technologies to ensure a stable supply of clean electricity as the country accelerates its shift toward renewable energy sources, according to a senior energy expert from the Institute of Electrical and Electronics Engineers (IEEE) Thailand Section.
Somporn Sirisumrannukul, an executive committee member of IEEE Thailand, said that over the next 5 to 7 years, several billions of baht are expected to be allocated by both state power utilities and private sector firms specialising in electricity transmission and distribution. The investment aims to enhance energy stability and support the nation’s decarbonisation goals.
As outlined in Thailand’s Power Development Plan 2024–2037, the share of renewable energy in the national power mix is set to rise sharply to 51%—a more than twofold increase from 22% recorded at the end of 2024. Meanwhile, the contribution of fossil fuels is expected to decline from 80% to 48%.
Somporn noted that as solar and wind power become more prominent, technology will play a vital role in managing their inherent supply variability. “Solar and wind are intermittent sources. Technologies must be smart enough to forecast when sunlight or wind will drop,” he said.
Such predictive tools are considered critical for managing electricity demand and ensuring uninterrupted supply. “This forecasting ability helps power providers plan how much energy is required from alternative sources,” he added.
Battery storage systems were also highlighted as essential infrastructure to provide backup power during periods of low solar or wind generation.
In addition, some utilities in Thailand are adopting demand response programs—software systems designed to efficiently balance power generation and consumption in real time. According to Somporn, these systems not only enhance energy management but can also reduce operational costs and lead to lower electricity prices in both wholesale and retail markets.
The spotlight on clean energy technologies comes ahead of a major international event hosted by the IEEE Power & Energy Society (Thailand). An academic conference and exhibition focusing on energy transition and carbon neutrality is scheduled to take place from November 26 to 29 at the Queen Sirikit National Convention Center in Bangkok. The event aims to bring together experts, innovators, and policymakers to explore the future of sustainable energy systems in Thailand and beyond.
