About IEX Market Coupling Case

Market coupling stems from a Central Electricity Regulatory Commission order that changes price discovery in the power market. From January 2026, Grid-India is set to collect all day-ahead market bids from every exchange and publish a single, cleared price, shifting this key function away from individual platforms such as Indian Energy Exchange.

Power trading in India currently relies mainly on the day-ahead market and the real-time market. At present, each exchange runs its own auctions where buyers and sellers submit bids, and separate prices emerge on every platform. Indian Energy Exchange dominates these segments, holding about 85% of total market share.

Alongside Indian Energy Exchange, the main entities active in power trading are Power Exchange of India and Hindustan Power Exchange. Trading for both the day-ahead market and the real-time market currently continues across these three platforms, even as the Central Electricity Regulatory Commission's order for market coupling remains under challenge before the appellate tribunal.
