Sailent Features

Matatila Power Station is located in Lalitpur district (UP), 60 K.m. far from Jhansi City. Nearest Railway Station is Jhansi on Delhi Bombay route.

Power Station is situated at left bank of river Betwa which rises from Bhopal in the Vindhyan Plateau at an elevation of 1550ft, passes through granite rocks at a sleep gradient, the river flows on outskirts of distt. Jhansi forming boundary line of U.P. and M. P and thereafter it mostly flows in U.P., meeting the river Yamuna in Hamirpur Distt in U.P.

It is entirely a rain fed river with very high discharge of water during rainy season and extremely low discharge during summers. The dam was constructed in year 1957 for irrigation purpose. Matatila power House with three machines of 10.2 MW each on the existing Dam has been commissioned in 1965.
