India’s Power Prices Hit Zero on

IEX

On 1 May 2026, India’s electricity prices on the Indian Energy Exchange (IEX) fell to zero for two 15‑minute blocks, a first in the country’s power market. The event highlights both the opportunities and challenges of India’s rapid renewable energy expansion, as the nation targets 500 GW non‑fossil capacity by 2030. While cooler weather and holidays dampened demand, record solar generation created oversupply, pushing prices down. Event Details Zero pricing: observed twice on 1 May in the real‑time market (RTM). Average price till 5 PM: ₹1.22/kWh. Supply-demand mismatch: Sell bids: ~46 GW. Purchase bids: ~6 GW (10:30–11 AM). Drivers: cooler weather, rainfall, gusty winds, and Labour Day holiday reduced industrial demand. Solar generation: record ~57.5 GW output. Market Context Power traded on exchanges = ~13% of total supply; rest via long‑term PPAs. Similar near‑zero pricing occurred on 5 April 2026 and 25 May 2025. Global parallels: South Australia, Southern California, and Europe have seen rising negative‑price hours. Expert Commentary Jayant Deo (ex‑IEX CEO): India may need to introduce negative pricing to balance demand and supply, as seen in Germany. Sunsure Energy: zero pricing signals need for flexibility, storage, and demand response, not a slowdown in renewables. Hexa Climate Solutions (Sanjeev Aggarwal): “It isn’t a demand problem; it is a grid‑balancing and storage problem.” Implications Grid stability: frequency management critical (India operates at 50 Hz). Storage solutions: batteries and demand‑shifting essential to absorb excess solar. Policy evolution: negative pricing mechanisms may be introduced to incentivize demand during oversupply. Investor concern: highlights volatility risks in renewable‑heavy markets.
