This paper estimates the effects of generation mix changes in the $7^{th}$ and $8^{th}$ Basic Plan for Long-term Power Supply and Demand from two aspects: economic efficiency through electricity prices and environmental performance through $CO_2$ and air pollutants(NOx, SOx, PM) emissions. Particularly, we examined additional generation mix conversion paths that take into account the trade-off between economic efficiency and environmental performance through scenario analysis. According to our results, the conversion from the $7^{th}$ plan to the $8^{th}$ plan should increase the electricity prices in the mid- and long-term, while reducing GHG and air pollutants emissions at the same time. The alternative generation mix that combines $7^{th}$ and $8^{th}$ plans shows that there exists a path to mitigate the trade-off between economic and environmental in the long-term. It will be next to impossible to derive a optimal generation mix that simultaneously considers the core values, such as supply stability, environmental performance, economic efficiency, energy safety and energy security, when establishing the power supply and demand plan. However, by exploring the effects of various generation mix paths and suggesting near-optimal paths, people can best choose their direction after weighhing all the paths when deciding on a forward-looking generation mix in the long term.

에너지경제연구원은 6월 20일, 정부의 전원구성안의 영향을 발전 비용, 온실가스, LNG 수요, 전력수급, 물가 및 GDP 차원에서 다각적으로 분석한 보고서를 발표했다. 보고서는 2016년에 탈원전-탈석탄 공약과 같이 원전과 석탄 비중이 대폭 줄어들고 신재생에너지 발전량 비중이 20%로 확대된다고 가정하고 발전 비용, 온실가스, LNG 수요, 전력 수급 영향 등을 2016년 실적치와 비교하였으며, 2029년 기준 제7차 전력수급기본계획(7차 계획) 대비 탈원전-탈석탄 시나리오에 미치는 영향을 제시했다. 보고서 전문을 게재한다.

This paper uses research on the Levelized Cost of Electricity (LCOE) in South Korea to conduct a simulation analysis on the impact of nuclear power dependency and usage rates on the social costs of power generation. We compare the $7^{th}$ basic plan for long-term electricity supply and demand, which was designed to increase nuclear power generation, to the $8^{th}$ basic plan for long-term electricity supply and demand that decreased nuclear power generation and increased renewable energy generation in order to estimate changes in social costs and electricity rates according to the power generation mix. Our environmental generation mix simulation results indicate that social costs may increase by 22% within 10 years while direct generation cost and electricity rates based on generation and other production costs may increase by as much as 22% and 18%, respectively. Thus we confirm that the power generation mix from the $8^{th}$ basic plan for long-term electricity supply and demand compared to the $7^{th}$ plan increases social costs of generation, which include environmental external costs.

영덕군 천지원전 건설이 확정됐다. 지난달 22일 정부의 제7차 전력수급기본계획 발표에 따라 2029년까지 신규원전 2기가 건설될 예정이다. 한수원은 이에 따라 영덕군 현지에 주민들과 원활한 소통을 하기 위한 '천지원전건설준비실'을 열었다. 천지라는 명칭은 원전이 들어서게 될 영덕읍 석리 노물리 매정리에 걸쳐 있는 '천지산'에서 따온 것이다.

We analyze economic effects of GHG reduction measures of the generation industry to meet 2030 GHG reduction target using the scenario based approach. We estimate the GHG emission of the Korean power industry in 2030 based on both the $7^{th}$ Electricity Supply & Demand Plan and the GHG emission coefficients issued by IAEA. We set up three scenarios for reduction measures by replacing the coal fired plants with nuclear power, renewable energy and carbon capture and storage. Once and for all, the nuclear power scenario dominates the other energy technologies in terms of GHG reduction quantities and economic effects.

This study analyzes how much cost the power generation and energy sector in South Korea have to bear due to the introduction of emissions trading scheme during 2016 - 2017. To this end, the data on the seventh basic plan for long-term electricity supply and demand is applied to the electricity market simulation model called M-Core, and then the model forecasts carbon dioxide emissions to compare with the free emission allowances in the first national emissions permit allocation plan. The main results are as follows. Carbon dioxide emissions are estimated to be less in 2016 but more than the free emission allowances in 2017. When the price of the allowances is changed from \10,000/ton to \20,000/ton, the cost of purchasing the allowances is ranged from \70 billion to \140 billion. Under the assumption that CO2 cost is incorporated into the variable cost, a reversal of merit order between coal and LNG generation takes place when the price of the allowances exceeds \80,000/ton.

This study analyzed the effect of power output reduction in coal fired power generation on the change of system marginal price and green house gas emissions. Analytical method was used for electricity market forecasting system used in korea state owned companies. Operating conditions of the power system was based on the the 7th Basic Plan for Electricity Demand and Supply. This as a reference, I analyzed change of system marginal price and green house gas emission by reduced power output in coal fired power generation. The results, if the maximum output was declined as 29 [%] to overall coal-fired power plant, system marginal price is reduced 12 [%p] compared to before and decreasing greenhouse gas emissions were 9,966 [kton]. And if the low efficiency coal fired power plant that accounted for 30 [%] in overall coal-fired power plant stopped by year, system marginal price is reduced 14 [%p] compared to before and decreasing greenhouse gas emissions were 12,874 [kton].

More than 8M tons of coal ashes are generated from coal-fired thermal power plants every year in Korea. Excluding the recycled portion (Current recycling rate: approximately 70%), all of the generated coal ashes end up in coastal landfills. Currently, the difficulties faced in establishing new ash treatment fields are attributed to the concerns raised over the environmental impacts caused by the landfills at individual plant facilities. Given the number of coal-fired thermal power plants to be built in the future (reflected in the 7th Basic Plan for Long-term Electricity Supply and Demand), building new ash treatment fields or seeking a new treatment plan seems unavoidable. Based upon a review of coal ash and its management, this study concluded that the most effective and fundamental strategy to minimize the environmental impacts resulting from coal ash landfills is to avoid constructing new coal-fired powerplants and furthermore, suggests that the practice of beneficial use and recycling the produced coal wastes should be encouraged.
