Abstract: In recent years, the integration of renewable energy sources has highlighted the need for effective volume risk hedging at the local level. However, conventional financial instruments, such as Wind Power Futures based on nationwide power output, are insufficient to meet local hedging needs. To address this gap, recent studies have explored efficient hedging methods using Principal Component Analysis (PCA) for diversified local needs, yet challenges persist in pricing and transaction models. In this study, we propose Principal Component (PC) derivatives for the solar power industry to efficiently mitigate cash flow volatility. This entails incorporating our previously developed prediction error derivatives using solar radiation as the underlying asset. Furthermore, we formulate Quanto PC derivatives that combine both solar radiation and price to simultaneously hedge volume and price risks. Empirical analysis shows that our PC derivatives outperform existing wide-area derivatives in terms of hedge effectiveness, requiring only three or four derivatives to achieve comprehensive coverage across different areas. In addition, these derivatives enhance hedge effectiveness by approximately 20 % compared to area-specific derivatives and are expected to improve market liquidity and create an efficient transaction framework. Our work underscores practical benefits and paves the way for further innovations in addressing complex pricing problems as well as in reducing potential transaction costs through countertrading in different areas.
