Indian Energy Exchange Ltd. (IEX), the country’s largest electricity trading platform, reported an 18.9% year-on-year increase in electricity trading volumes for August 2025, signaling its growing influence in India’s evolving power market.
The exchange recorded a total traded volume of 11,803 million units (MU) during the month, significantly ahead of the 4.4% growth in national power consumption, which stood at 150.47 billion units.
Real-Time Market Drives Growth
The Real-Time Market (RTM) remained the fastest-growing segment, posting a 44% surge to 5,029 MU. RTM now contributes 36% of IEX’s total volumes.
The segment also set a new milestone with a single-day record of 230 MU on August 31, underscoring the increasing demand for real-time power trading and flexibility in balancing energy requirements.
Day-Ahead Market Maintains Steady Momentum
The Day-Ahead Market (DAM) registered a 3% YoY growth, trading 4,797 MU in August. Accounting for 34% of IEX’s total traded volumes, DAM continues to serve as a crucial mechanism for advance scheduling and power supply optimization.
Green Energy Market Expands
Reflecting India’s clean energy push, IEX’s Green Market—covering both Green Day-Ahead and Green Term-Ahead contracts—rose 7% YoY to 930 MU. The growth highlights increasing integration of renewable energy sources into the trading ecosystem.
Price Trends
Despite higher volumes, average market clearing prices witnessed a decline due to improved supply liquidity:
- Day-Ahead Market (DAM): Average price fell 7% to ₹4.00/unit.
- Real-Time Market (RTM): Prices dropped 6% to ₹3.38/unit.
Lower prices offered distribution companies and bulk power consumers an opportunity to procure electricity at more competitive rates.
Renewable Energy Certificates (REC) Market
The REC segment also witnessed growth, with trading volumes rising 2.5% YoY to 21.68 lakh certificates. The average clearing price stood at ₹360 per certificate, reflecting sustained demand for green compliance obligations.
Summary
Indian Energy Exchange (IEX) registered nearly 19% YoY growth in power trading during August 2025, driven primarily by strong traction in the Real-Time Market and growing participation in green energy contracts. While traded volumes expanded, average prices eased due to improved liquidity, creating favorable conditions for buyers. The steady rise in renewable energy integration and continued momentum in REC trading underscore IEX’s pivotal role in shaping India’s electricity market.
