The Jigüey Dam is an arch-gravity dam on the Nizao River about 32 km (20 mi) west of San CristóbalinSan José de Ocoa Province of the Dominican Republic. At 110.5 m (363 ft) tall, it is the third highest dam in the country. The purpose of the dam is to produce hydroelectric power and it supplies the largest hydroelectric power station in the country.
The dam diverts water through over 4.4 km (2.7 mi) of headrace pipe and penstock to the power station downstream. The power station contains two 49 MW Francis turbine-generators for an installed capacity of 98 MW. The dam was completed and its power station was commissioned 1992. It cost US$500 million to build and funding was provided by the host government.[1][2][3]
