Assessing the Impact of Renewable Energy Sources: Simulation analysis of the Japanese electricity market


  • YOSHIHARA Keisuke
  • OHASHI Hiroshi


This paper evaluates the impact of renewable energy (RE) sources on market outcomes in Japan. We develop a simulation model to compute the kWh-market equilibrium, and conduct simulation exercises for 2015 and 2030. Using scenarios proposed by the government, we find that the diffusion of RE sources would lower the kWh-market prices and greenhouse gases by reducing fossil fuel consumption in 2030. It would also mothball many of the thermal power plants, which were active and profitable in 2015.
