In Wind, Commercial, distributed > in financial parameters, two discount rates are given which are REAL DISCOUNT RATE (RDR) and NOMINAL DISCOUNT RATE (NDR).
RDR does not incorporate inflation. Whereas NDR incorporates inflation.
You can edit (give input) in RDR. but you can not give input for NDR.
So, in every country there is inflation. Right!
SAM uses the NDR for financial analysis. So what is need of showing RDR? a new user like me initially was very confused! So i think there should be NDR for which we can give input and RDR should be removed. Because back end SAM uses NDR, same as HOMER Software. NDR should always be used as there is inflation in every country. RDR option should be removed.
