Its management system is defined by features such as diversity, open format, the large authority of program directors in budget allocation, personnel structure, project progress management, and quick decisions on continuing projects based on intermediate achievements. The programs cover a wide range of energy-related subjects, and are classified into power generation-transmission-distribution, energy and resource efficiencies, and transportation. Since the maturity level at the start of the projects is often relatively low, it is necessary to evaluate the results from the long-run view.
