Banpu Public Company Limited, or BANPU, is pressing ahead to strengthen its energy trading business in Japan's electricity market through Banpu Power Trading G.K., using AI technology to support electricity trading decisions under its Power+ group of power and related businesses. The company has developed two AI models. The first analyzes energy price trends, identifies trading opportunities, and assesses the confidence level of signals. The second evaluates overall market conditions to select trading approaches and determine trade sizes. Banpu tested both models in simulation between January and March 2026 using historical data from the Japanese power market, and found they produced better results than conventional trading methods. At present, the company has AI working alongside human traders, covering more than 90% of its total electricity trading volume across 6 regions, with traders still making the final decisions. Niti Pitakteeratham, Country Head for Japan at BANPU, said the goal of using AI to support electricity trading is not to have technology replace people, but to enhance traders' capabilities. Banpu is meanwhile studying the feasibility of extending its AI models to electricity markets in other countries, as well as to other businesses within the group.
