Electricity consumers in India may soon enjoy lower costs as the Central Electricity Regulatory Commission (CERC) reviews transaction fees charged by power trading exchanges. This initiative aligns with the CERC’s objective to implement market coupling, a major reform focused on enhancing price efficiency, boosting liquidity, and standardizing electricity prices across different trading platforms. The anticipated changes are expected to reduce overall power procurement costs in the long run.
Review of Transaction Fees
The CERC is evaluating the transaction fees set by power exchanges, particularly regarding the continued relevance of the current cap of 2 paise per unit. This review is timely, given the recent surge in trading volumes that necessitates a reassessment of the fee structure. An official revealed that a staff paper titled “Review of Transaction Fee charged by the Power Exchanges” is expected to be finalized by December 2025. One option being considered is a fixed transaction fee of 1.5 paise per unit for most trading segments, representing a reduction from the existing ceiling. Additionally, a proposal for a lowered fee of 1.25 paise per unit for term-ahead market contracts is under discussion, reflecting their longer duration and reduced operational demands.
Implementation of Market Coupling
Market coupling, which received CERC approval in July after extensive discussions, is slated for phased implementation beginning with the day-ahead market (DAM) in January 2026. This reform aims to consolidate buy and sell bids from all power exchanges, establishing a single market-clearing price. This shift is expected to replace the current system where prices vary across different exchanges. Industry experts believe this will significantly reduce price discrepancies, enhance generation capacity utilization, and allow buyers to access power at more competitive rates. As bids are aggregated across all exchanges, prices are anticipated to become more aligned, benefiting distribution companies and large consumers, ultimately leading to lower costs for end-users.
Growth of India’s Power Market
India’s exchange-based power market has seen impressive growth over the past decade. Since 2009-10, electricity traded through exchanges has increased more than sixteenfold, with total traded volumes exceeding 120 billion units in the 2023-24 fiscal year. While the day-ahead market previously dominated trading, segments like real-time, intra-day, and term-ahead markets are now capturing a larger share. Currently, the Indian Energy Exchange leads the market, accounting for nearly 90% of exchange-based trading volumes, while Power Exchange India Ltd (PXIL) and Hindustan Power Exchange Ltd (HPX) account for the remainder.
Future Implications for Power Exchanges
The transaction fee structures will become increasingly critical as exchanges move away from competing primarily on price discovery. With transaction fees generating over 95% of revenues for established exchanges, any changes to these fees could have a significant impact on the sector. Discussions regarding transaction fees are still in the early stages, and any modifications will be finalized after consultations with stakeholders. The overall aim is to improve efficiency, transparency, and affordability in India’s power markets, ensuring consumers benefit from a more streamlined and cost-effective electricity procurement process.
