The Central Electricity Regulatory Commission (CERC) on October 27, 2023, issued the Central Electricity Regulatory Commission (Sharing of Inter-State Transmission Charges and Losses) (Third Amendment) Regulations, 2023 to further amend the Central Electricity Regulatory Commission (Sharing of Inter-State Transmission Charges and Losses) Regulations, 2020.
The following amendment has been stated:
• In Sub-Clause (D) Of Clause (3) Of Regulation 5, which states “Components and sharing of National Component (NC)”, the following Proviso has been Inserted:
“Provided that where an inter-regional HVDC transmission system planned to supply power to a particular region is operated to carry power in the reverse direction due to system requirements, the percentage of Yearly Transmission Charges of such transmission systems to be considered in the National component shall be 30% or more by sub-clause (a) of Clause (1) of Regulation 6 of these regulations.”
• In Sub-clause (a) of clause (1) of regulation 6, which states “Components and sharing of Regional Component (RC)” has been substituted:
“(a) Regional Component of HVDC (RC-HVDC) comprising of 70% of Yearly Transmission Charges of HVDC transmission systems planned to supply power to the concerned region, except HVDC transmission systems covered under sub-clauses (a), (b) and (c) of Clause (3) of Regulation 5:
Provided that where an inter-regional High-voltage direct current (HVDC) transmission system planned to supply power to a particular region is operated to carry power in the reverse direction due to system requirements, the percentage of Yearly Transmission Charges of such transmission systems to be considered in the Regional component and the National component shall be calculated as follows:
HVDCr (in %) = (MW capacity of power flow in the reverse direction / MW capacity of power flow in the forward direction) X100
Where HVDCr (in %) is more than 30%, the Yearly Transmission Charges corresponding to HVDCr shall be considered in the National component, and the balance in the regional component
Where, HVDCr (in %) is equal to or less than 30%, 30% of Yearly Transmission Charges shall be considered in the National component and 70% in the Regional component:
Provided further that the MW capacity of power flow in reverse direction shall be certified by National Load Despatch Centre (NLDC) by way of actual power flow equal to such capacity; and”
This notification will come into force from October 27, 2023.
