Titulo Presentación Economic and technical evaluation of solar assisted water pump stations for mining applications: A case of study Paper to be presented at IEEE Paper to be presented at IEEE –IAS Annual Meeting Oct. 2015 IAS Annual Meeting Oct 2015 This paper presents a case of study of a solar system to assist the operation of a water pump station of a mineral operation in Chile. An economical analysis is carried out with respect to different design variables and the percentage of the total power required for operating the system in the less favorable conditions (degree of assistance) favorable conditions (degree of assistance). It demonstrates that the maximum net present value is obtained for the maximum assistance, i.e. supplying the full energy in the less favorable conditions. However, the internal rate of return will be maximized at the point where the system only supplies the energy to satisfy the full demand at the most favorable conditions. Finally the study shows that from an economical point of view PV technology is an attractive alternative to support the mining operation at present time.
