Power Market Coupling Draft Sinks IEX Shares 7%

Monday brought grim tidings for Indian Energy Exchange (IEX) investors, with shares sliding close to 7% to 126 rupees by early afternoon. Central Electricity Regulatory Commission (CERC)’s draft notification on power markets, featuring market coupling provisions, is the prime suspect behind the sell-off.

By soliciting views on coupling, CERC envisions a unified pricing process for electricity trades. Amid three exchanges—IEX holding a whopping 85% share, alongside Power Exchange of India and Hindustan Power Exchange—this shift promises a single market clearing price. Bids from all platforms would funnel to a nodal agency for price determination.

This overhaul spells trouble for IEX’s market leadership. Without distinct pricing advantages, traders lose reasons to prioritize IEX, especially in lucrative day-ahead and real-time trading where it generates bulk revenue. Analysts predict a hit to its edge and earnings.

History repeats: A 2025 CERC order on coupling once shaved 30% off IEX shares. Now, as feedback rolls in, the sector watches closely. Market coupling could foster efficiency and fairness, but at the cost of upending IEX’s stronghold, signaling a new era of balanced power trading in India.
