On behalf of the organizing committee, it is my great honor to welcome you to the International Conference on Power Engineering 2026 (ICOPE-2026), which will be held in April 2026 in Hangzhou, China. ICOPE is jointly sponsored and organized by the Chinese Society of Power Engineering (CSPE) and Japan Society of Mechanical Engineers (JSME). Since its inaugural conference in Tokyo in 1993, ICOPE has grown into a globally respected platform for the exchange of ideas and innovations in power engineering. It brings together experts from around the world to explore a wide range of topics across the energy field, excluding nuclear power generation. Over the past three decades, ICOPE has been held in cities such as Shanghai, San Francisco, Wuhan, Kyoto, and Charlotte. In 2026, the conference returns to China, continuing its tradition of international collaboration and technical excellence. We are delighted to welcome you to Hangzhou, one of China’s most beautiful and historic cities. Famous for its scenic West Lake and deep cultural roots, Hangzhou has also become a modern hub of innovation and sustainability. The city offers a unique blend of ancient elegance and contemporary progress, making it an ideal setting for discussions on the future of energy and low-carbon solutions.
