CAP_NEW discounting? - Antti-L - 19-12-2014
Tom on the VEDA Forum Wrote:Is it correct that CAP_NEW discounts from the middle of a period to it's start year if no NCAP_ILED is defined for a technology? In the global model, where periods have 10 years duration, this discounting factor increases the reported lump sum investment (LUMPINV) costs significantly compared to the calculation based on pure investment costs and new capacity (NCAP_COST x VAR_NCAP), in particular when NCAP_DRATE is high (e.g. as I assume for residential solar PV). No, there is no discounting from the middle of a period to its start
year. To get the lump-sum investment cost, all the annual investment payments
are just discounted to the beginning of the commissioning year |
