The commissioning dates of the Power Station are as under :-

Unit NO.1  -  09.05.1972

Unit NO.2  -  19.03.1973

Unit NO.3  -  19.07.1973

The generation was made on test basis upto 31.03.74 and the power station is handover to the then Rajasthan State Electricity Board on dated Ist April-1974.

At present the operation and maintenance of power station is done by the Rajasthan Rajya Vidhyut Uptadan Nigam Ltd. W.e.f. 15.07.2000, the date on which the original RSEB has been divided in 5 nos. companies by the Govt. of Rajasthan. However ownership of the power station is with Rajasthan Vidyhut Prasarn Nigam Ltd., which is the ancestor Company of erst while RSEB.

ACHIEVEMENTS:-

The performance of the power station remained in- credible since its commissioning. It has recovered all his construction cost within few years. Generation cost per unit comes between 4 P to 19P. The generation and PLF since commissioning of Jawahar Sagar power station have been enclosed at Annexure ‘A'.
