Tariff Orders

The State Electricity Regulatory Commissions (SERCs) and Central Electricity Regulatory Commission (CERC) determine tariffs for various transmission projects constructed under Section 62 of Electricity Act, 2003 within their jurisdiction. At the central level, the tariff orders are issued for each transmission line separately. On the other hand, the state commissions issues one tariff order for each transmission licensee on a regular basis.
