Pallivasal, located in the Idukki district of Kerala, holds a significant place in the state's history as the site of Kerala's first hydro-electric project. This project, established during the reign of Maharajah Sree Chithira Thirunal Balarama Varma, played a crucial role in meeting Kerala's electricity needs for decades. Situated about 8 kilometers from the popular hill station of Munnar, Pallivasal is not only an important historical site but also a beautiful destination for visitors seeking to enjoy the natural scenery.

The Pallivasal Hydroelectric Project, inaugurated in March 1940 by Travancore Diwan C.P. Ramaswamy Iyer, is nestled within the lush landscapes of Idukki. The project includes two reservoirs, two dams, a diversion dam, and a powerhouse located in the Chithirapuram area of Pallivasal Gram Panchayat. Over the years, additional units were commissioned, with the second unit coming online in February 1941 and the third in February 1942. In 1944, Ramaswamy Iyer also constructed the R.A. Headworks Dam on the Muthirapuzha River, a tributary of the Periyar River, to enhance the project's capacity.

The village of Pallivasal, with a population of just over 11,000 as of the 2001 census, is a tranquil and scenic place, making it an ideal spot for a relaxing picnic or a short trek. The area surrounding the hydroelectric project is characterized by rolling hills and lush greenery, offering stunning views that attract both locals and tourists. Visitors can explore the scenic spots on the slopes of Pallivasal and take in the beauty of the landscape.
