Prior to implementation of Fuel Supply Agreement (FSAs) i.e. prior to 1st April 2009, there was no uniform sampling modalities across the different Power Generating Companies taking coal from different subsidiary companies of Coal India Limited (CIL). The sampling was being done as per mutually agreed modalities between the particular Power Generating Company and the Subsidiary Company from where coal was being supplied. This was stated by Sh. Piyush Goyal, Minister of state for Power, Coal & New and Renewable Energy (Independent Charge) in a written reply to a question in the Lok Sabha today.
