Abstract
This study performs model analyses assuming the Japanese power supply portfolio in 2050 to evaluate the optimal generation portfolios that contribute to both economic growth and low-cost power supply by in 2050. The energy model developed in this paper is an integrated model which combines an optimal power generation mix model and an econometric model.
Considering the economic ripple effect, portfolios that include zero emission power generation do not necessarily decelerate the economic growth, even if the portfolios raise the electric price due to higher system costs. A balanced energy mix using not only zero-emission power generation but also an optimal amount of gas power generation can realize the harmonization between the environment and economic growth.
