The project involved the construction of a 26.27-kilometer, 6.50 meter diameter transbasin tunnel traversing Caraballo Mountains with a capacity of 80 m3/s capable of diverting at least 800 million m3 of water/year to the Pantabangan Reservoir. It also involved the construction of two (2) diversion weirs in Casecnan and Taan Rivers in Nueva Vizcaya including 80.46-kilometer access roads that connect to local municipal and provincial road networks. Two (2) generator sets were also installed generating a combined power of 150 MW and a 230kV Switchyard wherein the National Power Corporation’s (NPC) transmission lines were connected. The power produced in the plant is supplied to the Luzon Grid.
