The Indian Energy Exchange (IEX) saga continues as the Electricity Appellate Tribunal (APTEL) hearing on January 9, 2026, concluded without a definitive resolution on the controversial market coupling order.
What Happened Today at APTEL?
The much-anticipated hearing at 10:30 AM brought hope to IEX investors, but the Central Electricity Regulatory Commission (CERC) requested additional time to respond on withdrawing its July 2025 coupling order. This lack of clarity triggered significant volatility in IEX shares throughout the trading session.
IEX Stock Movement: A Rollercoaster Day
IEX shares demonstrated remarkable resilience during today’s volatile session:
- Intraday Low: ₹141.42
- Intraday High: ₹160.27
- Recovery: 7% bounce from day’s low
- Trading Price (11:05 AM): ₹149.87 (nearly flat)
This recovery comes after the stock suffered a devastating 30% crash following the original CERC order in July 2025.

Understanding the Market Coupling Controversy
What is Market Coupling?
Market coupling is an economic framework designed to create a single, uniform electricity price across all power trading platforms in India. Currently, three exchanges operate in this space:
- Indian Energy Exchange (IEX) – Market leader with 85% share
- Power Exchange of India (PXIL)
- Hindustan Power Exchange (HPX)
Current System vs. Proposed System
Current Model:
Buyers and sellers independently place bids on each exchange, resulting in separate price discovery across all three platforms. IEX’s dominant position gives it a significant competitive advantage.
Proposed Market Coupling (from January 2026):
Grid-India will aggregate energy prices across all platforms and publish a single unified price. Exchanges will only collect bids and forward them to the designated agency, effectively eliminating IEX’s competitive edge.
Why IEX is Fighting Back
IEX’s petition to APTEL claims the CERC order is:
- Arbitrary and unjust – Violates principles of natural justice
- Commercially devastating – Will result in market share loss without benefits
- Potentially corrupt – APTEL noted concerns about “theatrics” and whether regulations were made “for some officers to make money”
The Insider Trading Angle
Adding fuel to the controversy, APTEL expressed concerns about CERC’s independence, especially given:
- Sharp stock price decline immediately after the July order
- IEX’s allegations (citing SEBI) of potential insider trading
- APTEL’s observation that CERC should be “independent and above suspicion like Caesar’s wife”
What APTEL Said Today
The tribunal made several critical observations:
✅ Expects CERC to function in a fair and independent manner
✅ Wants assurance that CERC acted without external influence
✅ Expressed willingness to investigate if something is amiss
✅ Emphasized the need to avoid repeat incidents
However, before the hearing, CERC issued a circular stating that the July 2025 coupling order remains in effect, creating confusion about the commission’s actual intentions.

Timeline of Events
| Date | Event |
|---|---|
| July 23, 2025 | CERC issues market coupling order |
| July 24, 2025 | IEX stock crashes 30% |
| January 6, 2026 | CERC indicates willingness to withdraw order |
| January 9, 2026 | APTEL hearing; CERC seeks more time |
Impact on Different Market Segments
The coupling order affects two critical trading modes:
1. Day-Ahead Market (DAM)
Where electricity is traded one day before delivery – IEX’s stronghold
2. Real-Time Market (RTM)
Where electricity is traded closer to delivery time – another IEX-dominated segment
With market coupling, the advantage of trading on IEX disappears, as bidders would have little incentive to prefer one exchange over another.
What Investors Should Watch
📊 Next Hearing Date: To be announced
📊 Key Indicator: CERC’s formal response on withdrawal
📊 Stock Volatility: Likely to continue until resolution
📊 Implementation Timeline: January 2026 (if order stands)
Expert Analysis: What This Means
Best Case Scenario for IEX:
CERC withdraws the order completely, allowing IEX to maintain its dominant market position and pricing power.
Worst Case Scenario:
Order implementation proceeds, leading to significant market share erosion and revenue impact for IEX.
Most Likely Outcome:
A negotiated middle ground with modified coupling terms that balance competition with market stability.
The Bigger Picture: Market Competition vs. Monopoly
This case represents a fundamental question: Should India’s electricity trading market prioritize:
- Competitive efficiency through unified pricing (CERC’s view)
- Market-driven innovation through platform competition (IEX’s stance)
CERC argues that market coupling will improve efficiency and boost confidence among market participants. IEX counters that it will simply redistribute market share without creating real value.
Conclusion: Uncertainty Continues
Today’s hearing provided no closure for IEX investors and stakeholders. With CERC seeking more time and the tribunal emphasizing the need for independent, transparent functioning, the case remains in limbo.
For Investors: The 7% recovery from intraday lows suggests market participants are cautiously optimistic, but volatility will likely persist until CERC provides a definitive answer.
For the Industry: The delay extends uncertainty around the January 2026 implementation timeline, leaving power market participants in a planning vacuum.
Stay tuned to this space for real-time updates as the IEX market coupling case develops. The next hearing date will be crucial in determining the future of India’s electricity trading landscape.
