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.
The draft amendment is open for public comments and will be finalized by the CERC after due consideration. Once approved, the amended regulations will contribute to the efficient and equitable sharing of inter-state transmission charges and losses in the Indian power sector.
