This study introduces an adjusted PPA model in the local currency framework, suggesting that using tax revenue from the spillover effect of green electricity supply can be a suitable source of financing for PPAs. Developing countries can adopt this model to encourage private investment in green projects by reducing exchange rate risks and increasing returns on investment.
Investment volume in green projects, specifically in the green electricity market, suffers from limitations such as inadequate long-term financing, various risks, and a low rate of return on investment. Renewable energy power purchase agreements (PPAs), as a direct legal contract between a power provider and a power buyer, are one of the most popular instruments to increase investment. In this study, we model an adjusted PPA in the local currency framework to lower exchange rate risk and incremental tariffs by having the government pay part of the spillover tax revenues to the PPA, leading to a higher return on investment. The major conclusion of this study is that the use of tax revenue through the spillover effect of green electricity supply is a suitable source of financing for PPAs. As one policy implication, we recommend that developing countries allocate 50% of the tax revenue originating from power supply and adopt incremental PPAs to encourage private investment in green projects.
