The Binga Hydroelectric Plant is located at Barrio Binga in Itogon, Benguet Province. It is about 31 kilometers (19.3 miles) east of Baguio City and 19 kilometers (11.8 miles) downstream of the Ambuklao Hydroelectric Plant. From Baguio, the hydroelectric plant can be accessed through Itogon or by taking the same route that leads to Ambuklao Dam in Bokod. The route through Itogon is much shorter and has a better maintained roadway.
The construction of the Binga Hydroelectric Plant started in August of 1956 with the Philippine Engineers Syndicate, Inc. taking charge of the civil works. It took 3 years and 7 months to complete the project. Full operation of this facility began in March 31, 1960 - just about 3 years and 3 months after the Ambuklao Hydroelectric Plant was completed.
The dam which was constructed along the Agno River is 215 meters (705.4 feet) long and 107.37 meters (352.3 feet) high with a 94.50-meter (310 feet) long spillway. It is made of earth and rockfill and has 6 Tainter gates measuring 12.5 meters by 12 meters (41 feet by 39.4 feet) with hoists that are motor driven. The crest of the dam has an elevation of 586 meters (1,972.7 feet) and on top of the dam is a roadway which is 8 meters (26.3 feet) wide. To generate electric energy, the dam relies on a reservoir which has a drainage area of 936 square kilometers (361 square miles). The length of the reservoir at its widest portion is about 2 kilometers and the distance of backwater from the dam measures 10 kilometers.
For those who have enough time to spare and would like to enjoy the scenic drive through the Cordillera Mountains, it will be worthwhile to take the route through Bokod and then return to Baguio by way of Itogon. The views of the pine-clad mountains and the valleys and rivers below are just beautiful and worth seeing.
