RPS(Renewable Portfolio Standards)란 전력의 일정 양 또는 비율을 신$\cdot$재생에너지에 의하여 충당하도록 의무화하는 제도로써 정부지원에 의존한 신$\cdot$재생에너지 보급을 시장기능에 의하여 활성화하려는 새로운 정책도구이다. 본 논문은 이와 같은 RPS제도의 국내 도입에 대비하여 RPS의 기본 개념과 시장기구 하의 운용방식, 정책설계 시 고려사항 등을 살펴보았다. 이를 통하여 신$\cdot$재생에너지 전망 및 계획상의 문제점과 RPS도입에 따른 전력시장에서의 효과 등을 확인하고, 최종적으로는 향후 RPS도입을 위한 정책제언을 도출한다.

In 2012, Korea introduced a Renewable Portfolio Standard (RPS) scheme, replacing the Feed-in Tariff (FIT) scheme as a market support policy of renewable energy in the electricity market. RPS is to allocate obligatory quota of renewable energy sources for electricity suppliers, whereas FIT is to guarantee high prices for electricity from renewable energy sources. This study examines the effect of this policy change on solar photovoltaic market. According to the study, solar PV market grew fast under FIT as well as under RPS. However, under RPS the size of subsidy for solar PV suppliers was shrunk substantially. In addition, market risk increased severly under RPS due to the volatility of price of renewable energy certificate (REC) as well as of the electricity market price. The small and medium suppliers of solar PV were suffered the most severly from these policy effects. Therefore, the policy reform of RPS is needed to alleviate the market risk of small and medium suppliers of solar PV.

Recently the Korean government also has strictly restricted a law such as GBCC(Green Building Certification Criteria)and RPS(Renewable Portfolio Standard) on the construction. Especially the government announced a obligation of renewable energy consumption over 12% for all the public buildings of total area over 1,000㎡ since 2014. Regarding to the policy, this study presented the economics of energy analysis of the public office buildings that supplies 12% renewable energy output in the early stage of construction project. This paper calculated on CO₂ emission by the geothermal, solar heat, and solar photovoltaic system and estimated the saving cost. Reduced cost through the energy saving are predicted to influence on the total construction cost. As a result air pollution and energy saving cost are expected that renewable energy system would be saving total initial cost of construction on planning phase.

This paper analyzes the environmental impact and economic effect of introducing the Renewable Portfolio Standard (RPS) into the Korean electricity market using the DECADES (Database and Methodologies for Comparative Assessment of Different Energy Sources for Electricity Generation) model, a comparative assessment tool developed by IAEA. A bottom up approach is adopted for the evaluation of air pollutant emission and its impact of several RPS scenarios. The environmental damage costs of RPS scenarios are evaluated based on the Extern-E results and the Thailand externality study carried out by EGAT. The results of this study can be applied in determining or analyzing the national electricity policy and energy policy.

본 연구에서는 풍력에너지 보급을 위한 신재생에너지정책의 포트폴리오의 구성이라는 최종 목적 하에 먼저 적용 가능 수단 및 주요 쟁점사항에 대하여 고찰해 보았다. 먼저 FIT(Feed in Tariff)와 RPS(Renewable Energy Portfolio) 등 대표적인 신재생에너지 보급 정책들과 선진국 사례들을 중심으로 적용 가능한 그 외의 정책에 대하여 검토해보았다. 또한 이러한 정책을 시행하였을 때 성공여부에 영향을 미칠 수 있는 국내 주요 정책 변수에 대하여 조사해 보고, 향후 예상되는 국내 산업환경변화를 고려하여 장기적 전략수립을 위한 기초 연구를 수행하고자 하였다. 특히 이 과정에서 신재생에너지산업정책에서 공통된 주요 이슈들과 블레이드의 대형화나 해상풍력발전 등 풍력산업에서 차별화되어 나타나는 이슈에 대하여 검토하고 이러한 이슈들을 정책 포트폴리오 구성에 충분히 반영할 수 있도록 함으로써 현실과 동떨어진 정책연구가 되지 않도록 노력하였다. 이러한 연구는 신재생에너지 강국으로 도약하기 위하여 태양광과 풍력산업을 중심으로 다양한 발전전략을 세우고 있는 우리나라에서 풍력발전산업의 활성화를 위한 장기전략 수립에 기여할 수 있는 정책적 함의를 제공할 수 있을 것이다.

Global energy demand has continued to rise due to population increase and economic development. National governments and international bodies try to seek the ways to reduce the demand growth. Energy Technology Perspectives (ETP) have provided the current status of energy system, technology developments and external events that have changed ETP scenario since 2006. The status and prospects for key energy technologies of transport sector are presented. Technology portfolio for the transport sector should be needed to meet very low CO2 targets. The portfolio includes improved fuel economy of current internal combustion engine vehicles, advanced technologies such as electric and fuel-cell vehicles, advanced biofuels and demand-side management.

Renewable Portfolio Standard (RPS) is a regulatory policy that requires the generation companies to increase the proportion of renewable energy sources such as wind, solar, LFG, fuel cell, and small hydro. Recently, Korean government decided to increase the portion of renewable energy to 3% to total electricity generation by 2012 from the current level of 0.13%. To achieve this goal, an innovative plan for market competitiveness would be required in addition to the present Feed-In-Tariff (FIT). That is Korean government has taken it into consideration to introduce a Renewable Portfolio Standard (RPS) as an alternative to FIT. This paper reviews the impact of RPS on the long-term fuel mix in 2020. The studies have been carried out with the GATE-PRO (Generation And Transmission Expansion PROgram) program, a mixed-integer non-linear program developed by Hongik university and Korea Energy Economics Institute. Detailed studies on long-term fuel mix in Korea have been carried out with four RPS scenarios of 3%, 5%, 10% and 20%. The important findings and comments on the results are given to provide an insight on future regulatory policies.

Recently, Korea government decided to introduce RPS (Renewable Portfolio Standard) mechanism which requires electricity providers to gradually increase the amount of renewable energy sources such as wind, solar, bioenergy, and geothermal. As a consequence, it is expected that the long-term fuel mix would be changed to result in more expensive production and the increased production costs would be distributed to the rate payers via electricity tariffs. This paper presents the change in long-term fuel mix in year 2020 with the four RPS scenarios of 3%, 5%, 10% and 20%, and the methodologies for collecting the increased production costs through new tariff schedule. The studies on long-term fuel mix have been carried out with the GATE-PRO (Generation And Transmission Expansion Program) optimization package, a mixed-integer program developed by the Korea Energy Economics Institute and Hongik university. Three methodologies for distributing the production costs to the rate payers have also been demonstrated.
