Casecnan Dam

Casecnan Irrigation and Hydroelectric Plant is a dam diverting water from the Casecnan and Taan Rivers to the Pantabangan Reservoir through a 26-kilometre (16 mi) long tunnel located near Pantabangan and Muñoz in Nueva Ecija province of the Philippines. The multi-purpose dam provides water for irrigation and hydroelectric power generation while its reservoir affords flood control. It was considered one of the most expensive hydroelectric plants built in the country, being next only to San Roque Dam. The Casecnan Irrigation and Power Generation Project is also located in Rizal, Nueva Ecija. The P6.75-B Project provides irrigation to 26,920 hectares of new farms in the Science City of Munoz, Talugtog, Guimba, Cuyapo, and Nampicuan, all of Nueva Ecija. It generates 150 megawatts of power for the Luzon grid that will supply cheap electricity to millions of people in Luzon including Metro Manila.[1][2]
