Market coupling, an innovative mechanism aimed at creating a uniform market clearing price (MCP) across all power exchanges in a country, is poised to disrupt the current market structure of India’s energy sector. While it may boost competition in the short-term, the implications for dominant market players such as the Indian Energy Exchange (IEX) could be challenging.
Market Coupling: An Overview
Market coupling allows for the aggregation and matching of electricity buying and selling across power exchanges, ultimately leading to the discovery of a uniform MCP. This mechanism means that there will be a single price for electricity traded at any given time through the exchanges. The exchanges merely serve as platforms where buy and sell bids are received, and power is dispatched to buyers.
The Impact on IEX
IEX, holding a nearly 90% share of trading volumes, could face a potential loss in market share with the implementation of market coupling. This development caused IEX shares to hit a 52-week low of Rs 116 on the BSE on June 9, the day news broke about market coupling. Despite a small recovery, the shares are trading just about 5.69% above the 52 week low.

The Future of Power Exchanges
Currently, India’s power exchanges – IEX, Power Exchange India Ltd. (PXIL), and Hindustan Power Exchange Ltd. (HPX) – each have their unique buy bids, sell offers, and MCPs. With market coupling, this autonomy will disappear, and power exchanges will need to compete for volumes by offering better services and discounts on trading margins. This could prove advantageous for generation companies that sell electricity and distribution companies or industrial consumers, which purchase the power.

Potential Gains and Concerns
The uniform MCP and increased competition among power exchanges might even prompt these exchanges to offer discounts on their trading margins, currently capped at 2 paise per unit. Market coupling could indeed lead to higher liquidity and optimal utilization of power generation sources.
However, some argue it’s premature to predict the actual impact of market coupling. The government is yet to finalize the process, and the implications for trading volumes are still unclear.
IEX and the Way Forward
Satyanarayan Goel, chairman and managing director of IEX, contends that market coupling in the electricity sector should be considered only once the share of power exchanges in energy transactions reaches 15 percent or more. He emphasizes the need to focus on increasing market liquidity and size before moving towards market coupling.
As other exchanges prepare for the new landscape, technology is expected to play a significant role. If IEX’s dominance has been largely due to its tech-driven strategy, the other two exchanges will likely have to up their game in this area.
Conclusion
In conclusion, while market coupling introduces a new level of competition to India’s power sector, it also presents an opportunity for exchanges to differentiate themselves by enhancing their services and adopting innovative approaches. Despite the potential challenges for established players like IEX, the overall move could serve to invigorate the sector, ultimately benefitting consumers with improved service quality and competitive pricing.
