"The actual cost (Rs 9,479. 51 crore) of commissioning of the project exceeded the estimated cost (Rs 4,600 crore) by 106.08 per cent," it said.
"The cost overrun is mainly attributed to increased cost of engineering, procurement and commission contract, water storage system, railway siding, interest and finance cost due to time overruns and execution of works not envisaged in Detailed Project Report," the CAG report on PSU for the year ended March 31, 2016 said.
The contractual commission period of Unit-I and Unit-II was October 2011 and January 2012 respectively. The units were commissioned after delays of 31 months and 42 months respectively, it said.
The report noted that the project could not achieve the operational parameters fixed by the Rajasthan Electricity Regulatory Commission in respect of Plant Load Factor, Station Heat Rate, consumption of oil and auxiliary consumption.
