IEX shares plunged over 6% to the day's low of ₹127.50 on the BSE on Monday following the Central Electricity Regulatory Commission's latest draft framework for market coupling regulations. According to ETMarkets.com, this represents a significant decline from the stock's previous closing price of ₹135.81 on NSE. The market reaction reflects investor concerns about the framework's potential impact on IEX's dominant market position and operational structure.
The Central Electricity Regulatory Commission released a draft framework for market coupling regulations, naming Grid India as the Market Coupling Operator (MCO). As per ETMarkets.com, this comes after IEX's plea against CERC's earlier proposed framework on market coupling was dismissed. The framework aims to improve price discovery and efficiency by ensuring a uniform price in different electricity markets through a centralised mechanism, with price discovery to be conducted by the MCO from a date to be notified later.
IEX currently holds a 99.7% market share in power trading, making it the dominant player in India's electricity exchange market. According to ETMarkets.com, experts have pointed out that the proposed framework could disrupt the existing power market structure. The framework requires power exchanges to collect bids in a uniform format from market participants and transfer these anonymous bids to the MCO for aggregation and price discovery. Apart from IEX, India has two other power exchanges - Power Exchange India and Hindustan Power Exchange.
As reported by ETMarkets.com, Grid India, with CERC approval, shall formulate the Power Market Coupling Procedure (PMCP) for market coupling implementation within six months of the notification of these amendments. The commission has invited feedback from the public and other stakeholders by May 16, 2026. Until the new framework is implemented, power exchanges can continue their current price discovery processes, with the MCO handling price discovery for each market segment through aggregated anonymous bids.
IEX shares have declined around 28% in one year, with the market coupling framework remaining a key overhang for the stock. According to ETMarkets.com, the stock has gained around 5% in one week and over 12% in one month, but has declined more than 12% in three years. The stock rallied earlier this month after its board granted in-principle approval to explore a coal exchange, tapping into a nascent opportunity backed by the Ministry of Coal's Draft Coal Exchange Rules. Motilal Oswal Financial Services held a 'Neutral' rating for the stock with a target price of ₹127, implying a downside potential of more than 6% from the stock's previous closing price.
