9 Factor of Development and Promotion for Hydropower Contribution to the energy security Contribution to the prevention of global warming Long-term stability of the generating cost Function of a local energy Promotion of regional development and regional industries 1) Ripple effects of hydropower development 2) Promotion of regional industries

10 Target of Hydropower Development Present State Hydropower accounts for 10% of the total electric power supply and for 20% of the total installed capacity in Japan. Future Hydropower plays an important role Target of the total hydropower development is 20,700MW by FY2010.

11 Development Targets of Conventional Hydropower FY1990 (Developed) Output (MW) 19,310 Ratio (%) 11.2 FY2000 (Developed) Output (MW) 20,080 Ratio (%) 8.8 FY2010 (Target) Output (MW) 20,700 Ratio (%) 8.5 Development target of addition: 60MW/year Considerable effort is necessary to achieve this target Decrease of the economical undeveloped hydropower potential sites Increase public concern of the environmental conservation

12 Policy to Promote Hydropower Reduction of construction cost Application of new techniques Developing technology about simplified electric generation system etc. Reinforcement of hydropower development promotion and environment conservation Condition ordering to hydropower development promotion Simplification and review of criteria Enhancement of Subsidy System Introduction of RPS system etc.

13 Outline of the RPS System Type of Energy Covered Solar, Wind, Biomass, Hydro (up to 1MW), Geothermal Utilization Target The target for 2010 is 12.2 TWh, which would comprise 1.35% of national electricity supply. Fulfillment of Obligations ⅰ. By generation of electricity oneself ⅱ. By purchasing the new energy electricity from another party ⅲ. By purchasing an "New Energy Certificates" from another party
