As the denuclearization policy was officially abolished after the establishment of the new government, it is time to analyze the effectiveness of policy alternatives to achieve cost-effectively the greenhouse gas reduction in the power generation sector of 2030 NDC. This study quantitatively analyzes the impact of the policy combination of continuous operation of nuclear power plants and carbon tax on changes in greenhouse gas emissions and the electricity price through M-Core power market simulation. According to the results, both the carbon tax and the continuous operation of nuclear power plants contribute effectively to the reduction of greenhouse gases. It is, however, difficult to achieve both the alleviation of electricity-price increases and the reduction of greenhouse gases with a single policy. Therefore, if the carbon tax and the nuclear power plant operation policy are appropriately combined, it is expected to lay the groundwork for continuing to reduce greenhouse gas emissions in the power generation sector while suppressing electricity-price hikes by introducing the carbon tax.
