Idukki Arch Dam

The concept of building a dam across the Periyar River to generate hydroelectric power dates back to the British era. However, the project gained momentum in the 1960s, and construction of the Idukki Arch Dam commenced in 1969. The dam was completed in 1973 and became a crucial component of the Idukki Hydroelectric Project. The project involved the construction of two other dams, Cheruthoni and Kulamavu, along with the Idukki Arch Dam, to create a large reservoir. The reservoir's water is used to generate electricity at the Moolamattom Power Station, located underground. The construction of the dam involved significant engineering challenges due to the region's terrain and the scale of the project. Today, the Idukki Arch Dam stands as a testament to human ingenuity and a vital source of power for Kerala.
