Renewable Abundance: How Increased Solar and Wind Supply are Reshaping India's Energy Exchange

April 6, 2026

The Indian Energy Exchange (IEX) is witnessing a transformative shift in the country’s electricity markets. According to the latest trading data, green power trading volumes have surged, driven by a massive influx of renewable energy into the grid. This increase in supply—primarily from new solar and wind capacities—has led to a notable drop in clearing prices, making clean energy more competitive than ever for discoms and industrial consumers alike.

A key highlight of the recent market activity is the performance of the Green Day-Ahead Market (G-DAM) and the Green Term-Ahead Market (G-TAM). As renewable generation peaks during the spring and summer months, the surplus power is being channeled through the exchange, allowing for real-time price discovery that reflects the low marginal cost of wind and solar. For large-scale industrial consumers, this price dip offers a strategic window to fulfill their Renewable Purchase Obligations (RPO) at costs significantly lower than traditional long-term bilateral contracts.

However, the surge in volume also underscores the growing need for grid flexibility. While falling prices are a win for buyers, they present a challenge for developers who rely on merchant power sales for revenue. To manage this volatility, the market is seeing increased interest in Energy Storage and Hybrid bidding, which help smooth out the supply curves. As India continues its journey toward 500 GW of non-fossil capacity, the IEX is proving to be the critical “pressure valve” of the energy system—ensuring that every megawatt of green power produced finds a buyer at a market-clearing price that benefits the entire ecosystem.
