The Indian Energy Exchange (IEX) traded 358 million units (MU) of renewable energy during May 2023, a 28% increase from 280 MU traded in April and a 44% year-over-year (YoY) decrease.

The green energy traded in the market includes Green Day-Ahead Market (G-DAM) and Green Term-Ahead Market (G-TAM).

The total trading volume was 8,251 MU, representing an 8% YoY increase.

The trading price during May dropped by 30% YoY from ₹6.76 (~$0.082)/kWh to ₹4.74 (~$0.057)/kWh, due to the cooler weather conditions and improving supply side scenario leading to increased liquidity.

The supply-side liquidity is expected to improve further as the power demand trends upwards, leading to enhanced coal supply, reduced e-auction coal prices, and declining imported coal and gas prices, IEX said.

The improvement would help achieve competitive prices and higher clearance for DISCOMs and Open Access consumers.

According to GRID-India, energy met in the country during the month was 136.5 BU, a marginal 1% YoY increase.

Green Market: Day-Ahead and Term-Ahead

The Exchange traded 199 MU in the GDAM during May 2023, with a weighted average price of ₹5.20 (~$0.063)/kWh and 181 market participants.

The Real-Time Electricity Market (RTM) achieved the highest-ever monthly volume of 2,424 MU during May, a 13% MoM, and 5% YoY growth, with 719 participants.

The RTM segment’s consistent growth is driven by the increasing acceptance amongst distribution utilities and industries to efficiently balance the power-demand supply on a real-time basis.
