TheCirata Dam is anembankment dam on theCitarum River inWest Java, Indonesia. It is located 100 km (62 mi) southeast ofJakarta. It was constructed between 1984 and 1988 for the primary purpose ofhydroelectric &photovoltaic power generation. Other purposes include flood control,aquaculture, water supply and irrigation. The 125 m (410 ft) tallconcrete-face rock-fill dam is situated just before a sharp bend in the river and withholds a reservoir with a gross storage capacity of 2,165,000,000 m3 (1,755,194 acre⋅ft). The reservoir has a surface area of 62 km2 (24 sq mi) which caused the relocation of 6,335 families. The construction of the dam resulted in involuntary resettlement of 56,000 people.[1]
The hydroelectric power station is located on the north side of the river bend and contains eight 126MWFrancis turbine-generators. It has a total installed capacity of 1,008 MW and an annual generation of 1,426 GWh. The power station was completed in two phases, the second was completed in 1998. It serves mostly as apeaking power plant and is the largest hydroelectric power station in Indonesia.[2][3]
On 9 November 2023, thefloating solar panels that were built above the dam became operational. It has the capacity of 192 MW, making it the largest floating solar power plant inSoutheast Asia.[4]
The solar power plant alone is giving a contribution to theNet zero emissions of 245 Gigawatt-hours (GWh) of clean & renewable energy and reducing carbon emissions by 210,000 tons of CO2 annually.[5]
