The CAG in its reportfor year ending March 2015 also pointed out that the company concealed facts about actual capacity of the project which was increased to 1200 MW, 200 MW above the capacity of 1000 MW approved by the Central Electricity Authority (CEA).
Ram Mohan Johri, Principal Accountant General (Audit) Himachal Pradesh said that "Failure of the Energy department to detect capacity addition of hydropower project in time and non-levy of Rs 209.28 crore on account of capacity addition charges, additional free power royalty and local area development fund led to extension of undue favour to the power developer."
The estimated cost of the project, slated to Commissioned in 2011 was Rs 6903 crore.
However, the CEA detected in 2011 that the turbine of each generating unit procured by the promoter were designed for 300 MW, implying that the actual capacity was increased to 1200 MW which was 20 per cent more.
