Key Takeaways
- IEX shares dropped by 23% after CERC's market coupling announcement.

- Market coupling will centralize electricity pricing across exchanges.
- IEX risks losing its unique pricing power and dominance.

New Delhi, July 24 (NationPress) Shares of Indian Energy Exchange Ltd (IEX) experienced a staggering decline of 23 percent compared to the previous day's closing, subsequently becoming locked in a 10 percent lower circuit on Thursday. This significant downturn followed the Central Electricity Regulatory Commission’s (CERC) announcement regarding the phased implementation of market coupling across India’s power exchanges, which will commence with a three-month pilot program.
Starting from Rs 187 per share, IEX's stock plummeted by 10 percent to Rs 169.10 during the early hours, and has since continued to decline to a current price of 144.66, resulting in it being locked in the lower circuit.
Once the lower circuit is triggered, additional selling can only occur at that circuit price, although significant sell orders may remain unresolved until the circuit limits are revised or reset in the following session.
Historically, IEX and other power exchanges set electricity prices independently through their price discovery mechanisms. However, with market coupling, all buy and sell orders from various exchanges will now be aggregated, and prices will be established centrally, rather than by individual exchanges.
This centralization is expected to enhance efficiency and standardize electricity prices across the nation, but may also diminish the unique pricing power and market dominance that IEX has maintained thus far.
Given that IEX derives most of its revenue from high-volume trading in the Day-Ahead Market and Real-Time Market segments, the introduction of market coupling could significantly impact its competitive position and profitability.
The stock has seen a decline of 17.07 percent over the past year and 19.73 percent year-to-date.
Indian Energy Exchange (IEX) is the first and largest power exchange in India, operating an automated, nationwide trading platform for electricity and related instruments. IEX currently accounts for over 85-98 percent of the traded volume.
