TEPSCO not only covers all stages of projects from the feasibility study and detailed design to construction supervision - in the process, contributing to the world’s most generation-effective and reliable hydroelectric power plants - we have also for a long time, through our extensive experience with power utility companies in Japan, been providing technical solutions on the operations and maintenance of such plants.

With expertise accumulated in Japan, TEPSCO has also been engaged in many projects worldwide, including in Indonesia, Malaysia, India, Vietnam, and Bangladesh. TEPSCO can provide the above wide-ranging engineering services, including state-of-the-art techniques such as “adjustable speed pumped storage power generation” - based on experience from R&D on generators with their operating methods and reality of use.
