India's power sector is entering a new phase where market evolution is becoming as important as capacity addition. Electricity demand reached 1,707 billion units in FY26, while peak demand touched a record 270.8 GW in May 2026, underlining the scale of growth facing the sector. At the same time, installed capacity has crossed 550 GW, with non-fossil sources accounting for more than 54% of capacity. However, these resources contribute only about 29% of generation, creating increasing variability across hours, seasons and regions.
These developments are fundamentally changing how electricity must be procured and managed. Flexible resources, storage systems, responsive consumers and market-based balancing mechanisms are becoming critical components of a reliable power system.
The growth of India's short-term electricity market reflects this shift. While overall electricity supplied grew by only 0.9% in FY26, short-term market transactions expanded by 16.8%, reaching 302 BU. Exchange-based transactions alone increased to 168.6 BU, representing nearly 10% of total electricity supplied, compared with only 2.77 BU in FY09.
Enabling Greater Renewable Integration
The rapid expansion of renewable energy is creating new operational realities for electricity markets. India added a record 55.3 GW of non-fossil capacity during FY26, including 44.6 GW of solar power, while another 27 GW of solar capacity was added during the first half of 2026 alone.
As solar penetration increases, electricity prices are beginning to exhibit pronounced intraday volatility. In June 2026, exchange prices averaged approximately ₹1.63/kWh during solar-rich daytime hours, compared with nearly ₹8.10/kWh during evening peak hours, a five-fold difference. Real-time market prices touched near-zero levels during several daylight periods, while high-price events emerged during evening demand peaks and periods of supply stress.
Such price signals are not market imperfections; they are indicators of where flexibility is required. Electricity markets are increasingly becoming mechanisms through which storage assets, flexible generation and demand-response resources can capture value while enhancing system reliability.
Real-Time Markets Are Becoming the Nerve Centre of Grid Operations
One of the most important developments in India's power markets is the rapid growth of real-time trading.
Real-Time Market (RTM) volumes grew by 41% in FY26, far outpacing growth in conventional day-ahead markets. RTM volumes have now reached nearly 87% of day-ahead market volumes, and on certain occasions have exceeded day-ahead volumes altogether.
This trend reflects the increasing need for market participants to manage renewable-energy forecast deviations, optimise procurement costs and respond to changing grid conditions closer to delivery.
Looking ahead, proposed regulatory changes that shorten RTM timelines to within 30 minutes of delivery are expected to further increase the importance of automated trading, forecasting and digital decision-making.
Further Developments
India's power markets are increasingly evolving beyond the trading of electricity to creating value around flexibility, reliability and sustainability. Emerging developments such as Market Coupling are expected to enhance efficiency through unified price discovery, while proposed Capacity Markets can provide incentives for resource adequacy and grid reliability. At the same time, the introduction of Carbon Credit Certificate markets, the emergence of Virtual Power Purchase Agreements (VPPAs) and the development of Electricity Derivatives are expanding the role of exchanges into areas such as decarbonization, corporate renewable procurement and risk management. Together, these developments signal a transition from traditional energy trading platforms to integrated market ecosystems that support investment, grid resilience and India's long-term clean-energy ambitions.
