| 内容記述 | Economic feasibility of implementing small-scale hydropower generation systems installed at irrigation facilities has been anyalyzed in this study, using information from project areas that have undergone relevant surveys. The study also reports the results of interviews to project areas that have installed such hydropower plants. The results are as follows. (1) The average output is 850 kW for the 26 project areas that have installed hydropower plants as of 2007. (2) Construction costs of the existing hydropower plants are roughly in the range of 500-1,500 thousand Yen/kW, or 150-250 Yen/kWh. (3) If the selling price for electricity is raised in the future, hydropower plants could possibly be installed in project areas whose construction costs are less than 1,500 thousand Yen/kW and though more than 250 Yen/ kWh. We therefore evaluate feasibility on such project areas, and found that, at a selling price of 10 Yen/kWh, only 30% of potential projects could be pushed ahead with construction no matter how long the redemption years would be; at a price of 15 Yen/kWh, more than 60% could be pushed ahead at the redemption years of 25; and at a price of 25 Yen/kWh, the same 60% could be pushed at a shorter redemption years of 15. (4) According to our interviews, members of Land Improvement Districts possessing hydropower plants have such opinions as: a hydropower generation project can ease financial burdens of maintaining the Districts; such project however gives them some extra labor such as clearing debris in pipelines, restoring facilities from lightning damages, and water management; it is sometimes difficult to prepare funds for rehabilitating the plants; and it is necessary to simplify red tape concerning the projects with various government agencies. (5) The interviews also implied future directions for further promoting small-scale hydropower projects, such as: development of micro-scale hydropower generation technology; proposals for alternative frameworks of regulations; building consensus for water resources management; putting hydropower generation forward as one of major objectives of watershed management. | |||||||||||||||||||||||||||||||||||||
