The Indian Energy Exchange (IEX), the country’s leading electricity trading platform, reported a 14 per cent year-on-year rise in traded electricity volume, reaching 10,946 million units (MU) in May 2025. Additionally, the exchange recorded a sharp 65 per cent surge in Renewable Energy Certificate (REC) trading volumes, with 1.743 million certificates traded during the month.

According to government data for May 2025, national energy consumption declined by 4 per cent year-on-year to 148.7 billion units (BUs), owing to unseasonal rains and an early monsoon, which reduced electricity demand. However, increased generation from hydro, wind, and thermal sources improved supply liquidity on the exchange, leading to significant declines in market prices.

The Market Clearing Price in the Day-Ahead Market (DAM) stood at Rs 4.12/unit—down 22 per cent year-on-year—while the Real-Time Market (RTM) price dropped 28 per cent to Rs 3.43/unit. These competitive rates enabled discoms and commercial and industrial (C&I) consumers to substitute more expensive power purchases with exchange-based procurement.
