Banpu Public Company Limited announced progress in applying AI technology to support power trading decisions in Japan's electricity market under Banpu Power Trading G.K. The company has developed two AI models that combine traders' knowledge and experience with analysis of market data and energy price trends to assess trading opportunities, determine trade sizes, and manage risk. The first model analyzes data to assess energy price direction and identify trading opportunities, while evaluating the confidence of each signal. If a signal remains unclear, the system can reduce trade size or choose not to act in order to control risk. The second model assesses overall market conditions to determine trading approach and size in line with the situation. Both models underwent simulated power trading tests between January and March 2026 using historical data from Japan's electricity market, and delivered better results than conventional trading methods. Banpu has applied the AI models alongside traders in power trading in Japan's energy market for more than 90% of the company's total power trading volume across 6 regions, with traders still reviewing recommendations and making final decisions. Niti Pitakteeratham, Country Head – Japan, said that bringing in AI models does not mean technology will replace people, but rather enhances traders' ability to analyze large amounts of data and assess complex situations. The company also plans to study the feasibility of extending the AI models to power trading markets in other countries, as well as to other business groups.
