The revised tariff norms by the Central Electricity Regulatory Commission (CERC) will have a negative impact on the margins of state-owned utilities such as NTPC, Power Grid and NHPC according to Standard and Poor´s Ratings Services (S and P). CERC, in its final guidelines for tariff fixation, has shifted the incentive structure to plant load factor (PLF) from plant availability factor (PAF) for the period FY14-FY19.
