Outline of Final Research Achievements

The Study aimed at seeking the possibility to match the household electric power demand and supply from time-variant renewable energy through introducing a dynamic pricing.
The field experiment in a remote island revealed that the treatment effect of dynamic pricing was approximately 5% reduction compared to control group and pre-intervention period.
The result suggests that a dynamic pricing would be effective to mitigate the gap between demand and supply from renewable energy such as solar photovoltaic generation.

Academic Significance and Societal Importance of the Research Achievements

ダイナミックプライシングによる電力需要制御はこれまでおもにピークカットのために実証が進められてきた。一方、時間変動する再生可能エネルギー出力と需要をマッチさせる目的の研究は国内外をみてもほとんど例はなく、小規模ながらもフィールド実験でその効果を実証できたことは、研究成果の学術的意義である。
太陽光発電をはじめとする再生可能エネルギーの普及が進み、夜間・曇天時の供給不足だけではなく、昼間・晴天時の供給余剰による電力系統への受入れ停止といった事態も発生している。
ダイナミックプライシングを通じた需要側の行動変容で再生可能エネルギーをフルに活用できる可能性を示したことが本研究成果の社会的意義である。
