The Central Electricity Regulatory Commission (CERC) in New Delhi has issued a draft notification to amend the Central Electricity Regulatory Commission (Sharing of Inter-State Transmission Charges and Losses) Regulations, 2020. The proposed amendment aims to introduce changes to the calculation of transmission charges and losses for inter-state power transmission in India.


The amendment, titled the Central Electricity Regulatory Commission (Sharing of Inter-State Transmission Charges and Losses) (Third Amendment) Regulations, 2023, will come into effect upon notification by the Commission.

The draft amendment includes two key provisions. Firstly, a proviso will be inserted in sub-clause (d) of Clause (3) of Regulation 5 of the Principal Regulations, stating that a minimum of 30% of the yearly transmission charges should be applicable as per sub-clause (a) of Clause (1) of Regulation 6 of these regulations.


Secondly, a new provision will be added in sub-clause (a) of Clause (1) of Regulation 6. It addresses situations where an interregional HVDC (High Voltage Direct Current) transmission system, originally planned to supply power to a specific region, operates in the reverse direction due to system requirements. The provision outlines a formula to calculate the percentage of yearly transmission charges for such a transmission system. The calculation takes into account the maximum power flow in the reverse direction during any time block on a given day, the capacity of the HVDC transmission system in the forward direction, and the number of days in a month. Depending on the calculated value (referred to as HVDCr), the charges will be allocated between the regional and national components.
