Executive Summary & Key Takeaways

Executive Summary: This document details the Central Electricity Regulatory Commission's (CERC) Fourth Amendment Regulations of 2025 regarding the sharing of inter-state transmission charges and losses. It amends the 2020 regulations, introducing changes related to tariff regulations, terminal bays, and the allocation of transmission charges. The regulations come into effect from the date of publication in the official Gazette. Key Points / Main Content: Amendments to Regulation 2: * **Tariff Regulations Definition:** Defines "Tariff Regulations" as the Central Electricity Regulatory Commission Terms and Conditions of Tariff Regulations, 2024, as amended. * **Terminal Bay Definition:** Defines "Terminal Bay" with the same meaning as defined in the GNA Regulations. Amendment to Regulation 9: * **Allocation of Transmission Charges:** Specifies that Drawee DICs (other than state distribution licensees with separate GNAs not included in state licensees' GNAs) will have transmission charges apportioned based on their GNA relative to the state's aggregate ACUBC charges. Amendment to Regulation 12: * **Transmission Deviation Calculation:** Details the computation of transmission deviation for generating stations with dual connectivity to both inter-state and intra-state transmission systems. * **Information Sharing:** Requires STUs to share details of access with STU systems with NLDC and CTU. Amendment to Regulation 13: * **Inclusion of Offshore Wind:** Extends provisions to REGS based on offshore wind. * **Eligibility for Waiver:** Sets out eligibility criteria and drawal schedules for waiver of transmission charges for REGS/RHGS based on wind, solar, or their combination, as per Table 1. * **ESS Eligibility and Conditions:** Defines eligibility for waiver of transmission charges for Hydro PSP ESS (Table 2) based on construction award date. * **Hydro Generating Station Eligibility:** Specifies drawal schedules based on commissioning date as per Table 3 * **Offshore wind and Green Energy Source Eligibility:** Specifies drawal schedules for waiver of transmission charges for REGS based on offshore wind or green hydrogen or green ammonia plants (Tables 4 and 5). * **Extension for COD:** Allows for extension of time to achieve COD for REGS/RHGS/Battery ESS due to force majeure events, subject to certain conditions and approval processes. * **Self-Declaration for ESS:** Allows self-declaration for ESS regarding meeting electricity requirements, subject to verification by NLDC. Terminal Bays at ISTS Substation: * **Payment of Yearly Transmission Charges:** Defines the conditions for payment of yearly transmission charges for terminal bays by connectivity grantees in renewable power parks. * **Inclusion for Transmission Charge Determination:** Specifies inclusion of transmission charges for associated transmission systems and terminal bays that have achieved COD for determining DICs' transmission charges. Transmission System Availability: * **Calculation:** Transmission System Availability Factor is to be calculated as specified in relevant Tariff Regulations. Yearly Transmission Charges Calculation: * **Method:** Provides that Yearly Transmission Charges for elements where these are not available are to be worked out and provided by the Central Transmission Utility based on indicative capital cost, apportioning Yearly Transmission Charges approved by the Commission for the integrated project. Impact Analysis: Central Transmission Utility: * Impact: Required to calculate and provide yearly transmission charges for elements where these are not available, apportioning approved charges based on indicative capital cost. * Action Required: Implement the specified calculation method and provide necessary data. Drawee DICs (Distribution Licensees): * Impact: Subject to new rules regarding the allocation of transmission charges based on GNA. * Action Required: Understand and comply with the new allocation methodology for transmission charges. Generating Companies (REGS, RHGS, Hydro): * Impact: Subject to revised eligibility criteria and drawal schedules for waiver of transmission charges, including provisions for offshore wind and green energy sources. * Action Required: Assess eligibility for waivers based on the new criteria and comply with self-declaration and verification processes. Battery ESS Project Developers: * Impact: Subject to specific conditions for waiver of transmission charges, including requirements for charging from REGS and potential grid charging under contingency. * Action Required: Ensure compliance with charging requirements and self-declaration processes to claim waivers. NLDC and CTU: * Impact: Responsible for verifying compliance with electricity requirement criteria for ESS and for sharing information on access with STU systems. * Action Required: Implement verification processes for ESS and ensure data sharing with STUs.
