CERC notified the Central Electricity Regulatory Commission (Sharing of Inter State Transmission Charges and Losses) Regulations, 2020 ("CERC Sharing Regulations") on 4th May 2020. These regulations came into force with effect from 1st November, 2020 superseding Central Electricity Regulatory Commission (Sharing of inter-state transmission charges and losses) Regulations, 2010.
These regulations provide that the yearly transmission charges (YTC) as determined or adopted by CERC for transmission elements related to Inter-State Transmission System (ISTS) shall be shared amongst the users of such transmission systems. The users include generating stations, State Transmission Utilities, distribution licensee including State Electricity Board or its successor company, Electricity Department of State and any other entity directly connected to the ISTS and intra-State entity or a trading licensee that has obtained Medium Term Open Access or Long Term Access to ISTS (collectively referred as Designated ISTS Customers (DICs)). This YTC is shared amongst DICs on a monthly basis such that the YTC of all the inter-State transmission licensees and any adjustment thereof are fully recovered. As per Central Electricity Regulatory Commission (Sharing of Inter-State Transmission Charges and Losses) Regulations, 2020 the CTU is responsible for raising transmission bills, collection and disbursement of transmission charges to ISTS transmission licensees. The CTU collects transmission charges on account of raised bill for transmission system and disburses the amount so collected to the transmission licensees in proportion to their YTC.
Further, CTU has also formulated Billing, Collection & Disbursement Procedure as per Clause 3 of Regulation 23 of Central Electricity Regulatory Commission (Sharing of Inter-State Transmission Charges and Losses) Regulations, 2020.
