The Pulangi IV Hydroelectric Power Plant, also known as the Pulangi Dam, is located on the Pulangi River near Maramag in Bukidnon province on the island of Mindanao in the Philippines. It uses two reservoirs, produced by damming the Pulangi River, to supply water to a run-of-the-riverhydroelectric power plant; the power plant is capable of generating 255 megawatts (342,000 hp) of power.[2] Construction began in 1982; the first two generators became operational in December 1985, with the last generator being commissioned in 1986.[3]
Since operation, the reservoirs associated with the power plant have received an estimated 1,500,000 m3 (1,216 acre⋅ft) of sediment annually. Of the reservoir's combined 67,000,000 m3 (54,318 acre⋅ft) active capacity, 23,000,000 m3 (18,646 acre⋅ft) has been filled with silt. The siltation rate was almost 1 meter annually and caused the dam's reservoir to work at 50% capacity.[6] The unexpected siltation threatens safe operation of the dams and power generation, in addition to drastically shortening the predicted operational lifespan of the dam.[2] At first, the minimum and maximum water levels were raised and, in 2007, dredging work was performed around the head work of the upper reservoir's head. Selective dredging in the upper reservoir began in 2010, and continues as of 2011.[4][5]
The artificial lake created by the reservoir proper is called the Pulangi Lake or the Maramag.
