CEA ACCORDS CLEARANCE TO 520 MW PARBATI-III HYDROELECTRIC PROJECT


Central Electricity Authority has accorded techno-economic clearance to the 520 MW Parbati-III Hyderoelectric Project on the river Sainj, tributary of river Beas in Kullu district of Himachal Pradesh at an estimated cost of Rs.2228.41 crores for implementation in the Central Sector by NHPC. All the States of the Northern Regional grid would benefit from power generation at this central sector project, which is the last of the three proposed schemes. The proposed 750 MW Parbati-I Hydro-electric Project has not been found feasible due to environmental reasons and has been dropped and 800 MW Parbati-II Hydroelectric Project is already under construction. The Parbati-III Project would utilize the outflows from Parbati-II Hydroelectric Project and inflow from Sainj river.

The Parbati-III Hydroelectric Project envisages construction of an underground powerhouse having installation of four generating units of 130 MW each. The project would harness a net head of 326 m for power generation by constructing a 43 m high rock fill dam across the river Sainj; 7.98 km. long headrace tunnel of 7.25 m diameter, 113.75 m high, 20 m diameter surge shaft; 2 Nos. 375 m and 345 m long steel lined pressure shaft each bifurcating into 2 Nos. 3 m dia penstocks and 2.7 km. long tail race tunnel. The project would afford annual energy generation of 1977.23 million units in a 90% dependable year with 95% machine availability. The levelised tariff of the sale of energy for the project is estimated at Rs.1.87 per unit.

In the Beas Basin, Beas Sutlej Link Project(990 MW), Pong Dam (360 MW), Uhl Stage-I(110), Malana(86), Uhl Stage-II also called Bassi(60 MW), Baner(12 MW) and Gaj(10.5 MW) are the projects already commissioned and in operation. Largi, Uhl Stage-III and Khauli are under construction, Parbati Stage-II and Stage-III are estimated to provide 1320 MW. The power from the project would be harnessed to provide pollution free, clean and green energy to the Northern Regional power system.
