Banpu Public Company Limited has adopted AI technology to support electricity trading in Japan's power market through Banpu Power Trading G.K. The company developed AI models that combine the knowledge and experience of its traders with analysis of market data and energy price trends, in order to assess trading opportunities, determine trade sizes, and manage risk. Both AI models underwent simulated electricity trading tests between January and March 2026, using historical data from the Japanese power market, and delivered better results than conventional trading methods thanks to a better balance between returns and risk management. Currently, Banpu uses AI models alongside human traders for more than 90% of its total electricity trading volume in Japan's energy market across six regions, while traders continue to review the AI's recommendations and remain the final decision-makers. Niti Pitakteeratham, Country Head for Japan at Banpu, said AI is not replacing people but enhancing traders' ability to analyze large volumes of data and assess complex situations. Banpu also plans to study the feasibility of extending its AI models to electricity trading markets in other countries, as well as to other business groups.
