MARKET WATCH: IEX Electricity Trade Volumes Grow 15.9% YoY in Q1 FY2027

Executive Summary

The Indian Energy Exchange (IEX) recorded a robust operational performance for the first quarter of fiscal year 2027, achieving a total electricity trade volume of 37,534 million units (MU). This represents a 15.9% year-on-year (YoY) growth rate, propelled by persistent heatwaves and record-breaking national power demand that necessitated increased reliance on exchange-based procurement.

Peak Demand and Overall Volumes

The growth in exchange volumes closely tracked a significant surge in national energy requirements. Extreme weather conditions and a delayed monsoon forced a greater shift toward merchant power capacity to maintain grid stability during periods of peak load.

Demand Records:

• National Peak Demand: Reached an all-time high of 270.82 GW in May 2026.
• Quarterly Energy Consumption: Totaled 485.4 billion units (BUs), marking an 8.8% YoY increase.
• June 2026 Impact: June was recorded as the driest in over a decade with a 40% rainfall deficit. This deficit constrained hydro-generation, driving monthly consumption to 166.5 BUs—an 11.6% YoY growth—and forcing DISCOMs to seek immediate supply via the exchange.

Segment-Wise Performance & Pricing

Trade activity was characterized by aggressive procurement in the spot markets, resulting in double-digit price increases across major segments. While the Day-Ahead Market (DAM) provided essential baseload support, the Real-Time Market (RTM) solidified its role as a critical tool for high-frequency grid balancing.

The DAM segment, including High Price-DAM, reached a total volume of 13,344 MU for the quarter. The average market clearing price (MCP) for Q1 was ₹5.1 per unit, a 15.7% increase. However, the surge was most acute in June, where the MCP reached ₹5.2 per unit, representing a 32.4% YoY jump for the month.

The RTM segment emerged as the primary growth driver, recording 16,019 MU in Q1 (23.5% YoY growth). By June, the RTM segment accounted for nearly 44% of total exchange volumes, highlighting a structural shift toward high-frequency balancing as market participants manage intraday volatility.

Q1 FY2027 Segment Metrics

Renewable Energy Certificate (REC) Market

The REC segment experienced a severe contraction due to acute supply-side liquidity constraints. Total REC volumes for Q1 FY2027 plummeted by 81.4% YoY, totaling 9.77 lakh certificates. This decline was underpinned by a significant 86.1% drop in sell bids across the quarter.

The downturn peaked in June 2026, with volumes falling 92.3% YoY (2.49 lakh certificates). A 85.9% decline in sell bids during the month placed sustained upward pressure on clearing prices.

In the June 2026 trading sessions, clearing prices were recorded at ₹400 per REC (June 10 session) and ₹395 per REC (June 24 session), reflecting the impact of reduced sell-side liquidity.

Regulatory Context & Market Overview

IEX is currently navigating a period of significant structural and regulatory transition, impacting its historical “liquidity moat” as the dominant price-discovery platform.

CERC REC Amendments The Central Electricity Regulatory Commission (CERC) has notified the first amendment to the 2022 REC regulations, introducing a revised multiplier framework for projects commissioned after the amendment. Multipliers are now assigned based on a weighted criteria framework:

• Weighting Criteria: Tariff range (40%), technology maturity (30%), and capacity credit/peak support (30%).
• Technology Multipliers: Solar and Wind are assigned a 1.0 multiplier, while Offshore Wind receives a 4.0 multiplier, valid for 15 years.

Market Coupling Transition Following the phased implementation of market coupling in January 2026, the exchange is transitioning from a price-discovery lead to a bid-collection platform. This regulatory shift commoditizes the exchange by mandating uniform price discovery across all platforms, requiring IEX to innovate within its Green and Real-Time segments to sustain its market position.
