Core Purpose

Regulations issued by the Central Electricity Regulatory Commission under the Electricity Act, 2003 establishing definitions, scope, and the methodology for computing and charging deviations by grid-connected sellers and buyers under a Deviation Settlement Mechanism.

Detailed Summary

The Central Electricity Regulatory Commission (the Commission), exercising powers under the Electricity Act, 2003 (36 of 2003), sets out definitions, scope, and a methodology for the Deviation Settlement Mechanism applicable to all grid-connected regional entities engaged in inter-State purchase and sale of electricity. The regulations define key terms including Actual Drawal/Injection, Ancillary Services (referencing the Central Electricity Regulatory Commission (Ancillary Services) Regulations, 2022), Area Clearing Price (ACP), Available Capacity, Contract Rate, Deviation, Grid Code (specified under clause (h) of sub-section (1) of Section 79 of the Act), Interface Meters (referencing the Central Electricity Authority (Installation and Operation of Meters) Regulations, 2006), Open Access Regulations (Central Electricity Regulatory Commission (Connectivity and General Network Access to the inter-State Transmission System) Regulations, 2022), Reference Charge Rate (RR), Renewable Rich State (1000-5000 MW combined solar/wind capacity) and Renewable Super Rich State (5000 MW or more), and WS (wind-solar) Seller. Regulation 6 sets out formulas for computing deviation (in MWh and percentage) separately for general sellers, WS sellers (with a transitional formula applicable up to 31 March 2026 and a revised formula thereafter based on a Commission-stipulated percentage 'X' following public consultation), and buyers, referencing the Deviation and Ancillary Service Pool Account under Regulation 9 and Load Despatch Centres (National, Regional, or State). Regulation 7 defines the Normal Rate (NR) of Charges for Deviation as the highest of the weighted average ACP of Integrated Day-Ahead Market and Real-Time Market segments across all Power Exchanges, or a weighted combination of both with an Ancillary Service Charge component. Regulation 8 prescribes tiered charges for deviation linked to grid frequency bands (49.90 Hz to 50.05 Hz) for general sellers other than Run-of-River (RoR) and municipal solid waste (MSW)-based generating stations, ranging from zero to 200% of the Reference Charge Rate, with separate frequency-independent structures (up to 110% of RR) for RoR generating stations, contract-rate-based charges for MSW-based generating stations, and volume-limit-tiered contract-rate charges (up to 200% of contract rate) for WS Sellers, including those aggregated at a pooling station through a Qualified Coordinating Agency (QCA).
