Indian Energy Exchange (IEX) reported a 16.5% year-on-year surge in electricity trading volumes for October 2026, reaching 13.1 billion units. Strong gains in the Real-Time Market and Term-Ahead segments helped balance declines in the Day-Ahead and Green markets, as energy prices saw significant annual spikes despite mid-month demand fluctuations.
Indian Energy Exchange Reports 13.1 BU Volume in October 2026
Total electricity volume grew 16.5% YoY to 13.1 billion units, while REC trading surged 97.5%.
Reader Takeaway: Strong Real-Time and Term-Ahead market volumes offset Green market declines; watch power demand and price volatility.
What just happened
Indian Energy Exchange (IEX) saw its total electricity volume reach 13.1 billion units (BU) in October 2026, a 16.5% increase compared to the same month last year. While the Real-Time Market (RTM) grew 23.7% to 5,670 MU and the Term-Ahead Market (TAM) surged 138.8% to 2,175 MU, the Day-Ahead Market (DAM) contracted 3.8% to 4,508 MU. The Green Market also saw a 30% decline, recording 738 MU.
Why this matters
IEX remains the primary barometer for India’s spot power market. The sharp year-on-year price increases in DAM (up 149%) and RTM (up 112%) reflect high power demand, which grew by 21.9% nationally to 159.8 BU. These figures demonstrate how IEX manages volatility arising from shifting weather patterns and extreme climate events.
The backstory
Management noted that October 2026 was a tale of two halves. The first half was characterized by high demand due to warmer weather, whereas the latter half saw a cooling effect from rain and Cyclone Arnab. This weather shift eased power demand and created supply liquidity, allowing for intermittent near-zero price blocks in the RTM.
Risks to watch
Regulatory intervention in spot market pricing, shifts in government renewable energy mandates affecting REC demand, and climate-induced volatility remain core risks. Additionally, prolonged periods of low demand and high supply liquidity can compress the exchange’s clearing price premiums.
What to track next
The company’s ability to sustain volume growth in the Green Market and the impact of further transmission infrastructure expansion on spot market liquidity will be critical for quarterly margins.
