In early 2011, it became mandatory for all power procurement to be made through the tariff-based competitive bidding (TBCB) mechanism. The TBCB philosophy ensures that the procurer of power gets the best possible tariff. There is no distinction between public or private sector suppliers of power. While much efficiency has been achieved through the TBCB modality in conventional power, the positive impact of TBCB is now being felt in the renewable sector as well.
