Outline of Final Research Achievements

We have achieved mainly three results. First, a monograph was published in English, which surveys promotion programs for renewables, particularly focusing on a feed-in tariff system, where a set price is applied to the electricity produced from renewable energy sources (RES-E) during a set period of years.
Second, a new payment system was proposed for the efficient and stable use of RES-E in society after some diffusion of renewables. Given a set of RES-E producers and electricity consumers, it prescribes a payment depending on the comparison between production and consumption during a period of time, say 15 mins. Third, simulation was conducted to illustrate how the payment system proposed will be running.

再生可能エネルギーのための制度設計

Academic Significance and Societal Importance of the Research Achievements

技術開発とさまざまな普及策の実施によって、再生可能エネルギーの利用は拡大しつつある。本研究は、普及後に再生可能エネルギーを社会で効率的、安定的に利用するための新たな経済制度を考案した。それは、ローカルな電力需給均衡を目指した報酬制度で、再生可能エネルギーの小規模分散型発電という特性を考慮に入れている。制度自体は簡便で、シミュレーションにより実用性も示した。これを従来の大規模集中型電源のための制度と組み合わせることで、再生可能エネルギーを電力システムに組み込みことが可能になる。
