In renewable energy, there are three main situations where quantitative and qualitative valuations must be carried out so as to make sound and informed investment, financing or commercial decisions. The first is when preparing a bid for an auction or defining a reasonable price for a PPA negotiation. This evaluation could be more or less detailed (in general less detailed than the one required before making a final investment decision or before financial closing to start construction). The second situation is when selling shares of the project company to a third company (or when purchasing shares, depending on which perspective the transaction is considered, either from the perspective of a potential investor or of the sponsor/seller). In this case, the evaluation will not be focused on the offtake price (e.g. estimation of LCoE + required margin) but on the value of the project at the time of the shares purchase or sale (e.g. estimation of the project’s NPV). The third situation in which such valuations are carried out is in case of refinancing, either following a stress situation or simply for the sake of improving the initial funding conditions. Practicing with real-world cases allows a better understanding of theoretical concepts and helps connect with already known concepts, although limitations exist because of the different existing approaches.
