Tajo de la Encantada Dam
Tajo de la Encantada Dam (Contraembalse) – Villaverde Dam
The Tajo de la Encantada Dam was desgned with two reservoirs at diferent level, joined by a large water pipe. In the one on the lower level there are several electricity-generating turbines and they are operated with the water pressure from the upper reservoir (Villaverde Dam, near the Bobastro ruins).
At night, when energy is less expensive, these turbines will become drive motors and the lower water reservoir is pumped to the top. The next day, the process starts draining the water supply. The business is in the difference in price of electricity day and night.
The Tajo de la Encantada Dam is located on the edge of the tagus, in the Chorro, municipality of Álora, where the hydroelectric company has inmplemented the largest reversible hydroelectric in Spain, Salto de la Encantada.
