Loss of Revenue because of Non functionig of the units

''If coal is not mined the loss is much more than what has been assessed by the CAG. The non- availability of coal  has been the major handicap for power industries and this has affected the economy very badly. After allocating the mines, if they have not functioned, the  situation is still worse and this should have  caught the attention of the Govt to set things right.This only indicates the Government's supervision in vital areas is missing and thererby causing severe damage to production and revenue gains. This calls for an other assessment of loss to the exchequer and the economy.''
 This is in response to FM's remark that if the units to whom coal mines have been allocated have not functioned where is the loss?
