Opposition Leader Calls for Investigation into Solar Project and Promotion of Salt-Battery Industry

On October 28, 2026, Natthaphong Ruengpanyawut, a list-MP and leader of the People's Party, addressed the media at the Thai Parliament regarding the government's public solar energy project. Natthaphong confirmed that his party is actively investigating whether the project’s procurement processes unfairly favor large corporate entities.

Beyond oversight, Natthaphong emphasized the need for a structural energy transition. He noted that solar power cannot provide 24-hour energy, necessitating large-scale grid-connected battery storage. He highlighted the potential of salt-battery technology developed by Khon Kaen University (KKUVOLT), which utilizes abundant salt mineral resources found in Northeast Thailand. According to Natthaphong, this technology is competitive in terms of quality and price on the global market.

For residents and stakeholders, this development is significant as it highlights potential shifts in national energy policy. The People's Party is urging the government to provide a clear roadmap for energy transition to attract investment into the local battery sector. Whether the government will adopt these recommendations or if the investigation into the solar project will reveal irregularities remains to be confirmed. The party continues to push for a policy framework that supports local content and sustainable energy infrastructure.
