| Pallivasal Hydro Electric Project is the first power project of Kerala State. There are two dams and one diversion weir as part of this project. These are Kundala Dam, Maduppetty Dam and R A Head works. The Maduppetty Dam is located at about 15km upstream of R. A. Head works and Kundala Dam is further upstream and is about 12 km from Maduppetty Dam. The water stored in the Kundala reservoir is released through the stream to Maduppetty Dam located downstream. The water stored in the Maduppetty reservoir is released to downstream through a dam toe power house. The controlled release from Maduppetty Dam reaches the diversion weir (R.A. Head works) and from there, the water is diverted through a water conducting system to the power house of Pallivasal HEP located on the right bank of Mudirapuzha river. After generating power, the tail water is pumped to the balancing reservoir of Sengulam Hydro Electric Project and the surplus water from the sump of pumping station is spilled to the Mudirapuzha river itself. |
