, the first hydro 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. Ramaswamy Aiyer Headworks is located downstream of Maduppetty Dam near Munnar. The water stored in the Kundala reservoir is released through the stream to Maduppetty Dam located downstream. From the Maduppetty reservoir the water is released to downstream through a dam toe power house. The controlled release from Maduppetty Dam reaches the diversion weir named 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.
