The government has implemented various support systems, such as competitive bidding auction systems, to expand the dissemination of renewable energy and address the associated economic challenges. However, there is no mechanism for the general public to indirectly invest in renewable energy projects or withdraw funds early for reinvestment. Recently, innovative financial services employing Security Token Offerings (STO) have emerged, allowing fractional investments in real estate or copyrights through blockchain technology. These services enable investors to recover funds early and secure future profits. This study proposes a renewable-energy-based financial model that enables the general public to make fractional investments in renewable energy power plants using innovative financial services, while allowing also renewable energy businesses to recover their investment funds early for reinvestment. Simulations and policy comparisons were conducted to analyze the design of underlying assets, participant profits (trading platforms, asset managers, and trust companies), and the effectiveness and limitations of this model. According to the analysis, the Power On DABS (Digital Asset Backed Securities) On (PODO) model can provide reasonable returns, creating sustainable service. Additionally, by utilizing STO, the model can create a new distribution market and enhance the efficiency of power generation management, thereby increasing the value added. A comparison with existing support systems showed that the PODO model complements current policies, which could help shift renewable energy distribution from government-driven support (loans and subsidies) to a market-based approach. However, exemptions through regulatory sandboxes are required to implement the PODO model.
