| Abstract |
The RE100 (Renewable Energy 100%) campaign is a voluntary initiative at the private level to procure 100% of a company's electricity consumption with renewable energy. Although multiple companies in South Korea have announced their participation in RE100, the number of participating companies is still very limited compared to other developed countries for both regulatory and economical reasons. In this study, we analyze various renewable energy purchasing methods for participating in RE100 and demonstrate that power purchase agreements (PPAs) are the most efficient method for achieving the national renewable energy target in South Korea. Afterward we suggest the economical and regulatory prerequisites that should be prepared for the activation of PPAs |
