Pinalito Hydroelectric Project

The Pinalito Hydroelectric Power Plant in the Dominican Republic, with a 57-meter high RCC dam on the Tireo River, required comprehensive geotechnical monitoring during construction. Encardio Rite supplied instrumentation for risk assessment, including temperature meters, piezometers, and a seepage monitoring system. The monitoring system also included borehole extensometers with displacement sensors and digital tape extensometers, ensuring accurate data collection for structural performance and safety. The project, executed from 2004 to 2008, utilized this data for risk mitigation and operational efficiency.

Pinalito Hydroelectric Project

The 50 MW Pinalito Hydroelectric Power Plant was built by Odebrecht for the Corporación Dominicana de Electricidad. The scheme included a 57 m high and 210 m in the crown dam, a reservoir, an open-air hydroelectric central with two generation units of 25 MW each, a sub-station of two 10 km long water intake tunnels, and water distribution pipes.
