Valuation and Risk Modeling of Renewable PPAs

Abstract

[Abstract] Renewable energy (RE) projects aim to sell electricity to the consumers, which may be carried out by means of a Power Purchase Agreement (PPA). These PPAs will yield payments over a long period of time so as to refinance the project. Nevertheless, the present literature which addresses the economic appraisal of renewable energy projects focuses on the project developer and whether an onsite PPA is deemed, the actual cost of energy is not taken into consideration and nor the embedded options of the PPA.We propose such a model and carry out a comparison with the most common approach, a swap between fixed and market price
