description |
Sedimentation reduces the useful life of reservoirs and the value of hydropower plants. The aim is to determine the effect of sediment management decisions on the value of a plant. First, management alternatives are ranked with the AHP technique according to the perception of six experts. Second, the plant is valued by cash flow (FCL) and RESCON 2 BETA (RES). Results shows three alternatives ranked: reforestation, agriculture and dam construction. The useful life of reservoir increases in 84% (reforestation), 40% (agriculture), and 76% (dam). The value of the plant increases in 21% (FCL) and 21.74% (RES) for reforestation, 11.59% (FCL) and 13.18% (RES) for agriculture, and 20.07% (FCL) and 19.93% (RES) for dam building. It is concluded that sediment management affects the value of the plant since the useful life of the reservoir affects the value of continuity. © The author; licensee Universidad Nacional de Colombia. |
