India Power Sector Report: March 2026 Consumption and Peak Summer Forecast

March 2026 Consumption Summary

India’s power consumption reached 149.56 billion units (BU) in March 2026, representing a year-on-year growth rate of 1.8% compared to the 146.92 BU recorded in March 2025. The peak power demand met during the month rose to 238.37 GW, a month-over-month increase when compared to the 235.22 GW recorded in the late winter month of February 2025. This data reflects a period of controlled demand growth across the national grid during the transition to the summer season.

Consumption Breakdown and Influencing Factors

The marginal growth in consumption during March 2026 was largely dictated by atmospheric conditions. Unseasonal rains and lower-than-expected maximum temperatures—driven by eight western disturbances compared to the historical average of five or six—suppressed the early deployment of cooling loads. The Day-Ahead Market (DAM) prices on the Indian Energy Exchange (IEX) remained at approximately 6.75 ₹/kWh as of late April, indicating a balanced supply-demand equilibrium prior to the projected summer spike.

Electricity demand across residential, commercial, and industrial segments remained stable, influenced by the following factors:

• Weather Mitigation: Intermittent rainfall in northern regions reduced the immediate necessity for air-conditioners and desert coolers.
• Structural Efficiency: The continued adoption of LED lighting and the optimization of industrial processes have contributed to moderating the underlying demand trajectory.
• Market Stability: Stable industrial activity and a gradual improvement in commercial consumption prevented extreme volatility in grid loading.

Summer 2026 Forecast (April–June)

The Ministry of Power has projected a peak demand of approximately 270 GW for the summer of 2026. This forecast represents a 8% step-up over the previous all-time high of 250 GW recorded in May 2024. In response to volatile natural gas prices exacerbated by the ongoing Middle East crisis, the government has prioritized coal and renewable integration. Emergency and preventive measures for the April–June window include:

• Maintenance Deferment: Planned maintenance for thermal power stations has been postponed, ensuring an additional 10,000 MW of capacity is available.
• Operational Directives: The 4,000 MW Coastal Gujarat Power Ltd. plant has been directed to operate from April 1, 2026, to support supply across Gujarat, Maharashtra, Rajasthan, Haryana, and Punjab.
• Strategic Hydro Conservation: Hydroelectric stations are being operated to conserve water ahead of the probabilistic transition to El Niño conditions starting in May 2026. This conservation is critical as El Niño typically suppresses monsoon rainfall and hydroelectric generation later in the year.
• Supply Planning: To offset the potential 10 GW shortfall in gas-based generation during non-solar hours, the Centre has advised Coal India Limited to utilize revised SHAKTI Policy auctions to bolster fuel supply to generating companies.

Supply-Side Status and Generation Mix

India’s total installed generation capacity reached 532,739.71 MW as of March 31, 2026. The fiscal year witnessed the commissioning of several high-capacity thermal units, including the 800 MW Unit-1 and Unit-4 of the Yadadri Thermal Power Station, the 800 MW Unit-1 of the Patratu Thermal Power Station, and the 800 MW Unit-6 of the North Chennai Thermal Power Station Stage III. Further additions included 660 MW units at North Karanpura, Barh, and Obra C.

All India Installed Capacity by Source (as of March 31, 2026)

Within the renewable segment, Solar (150.26 GW) and Wind (56.09 GW) continue to lead growth, with a record 6.1 GW of wind capacity added during the 2025–26 fiscal year. Coal remains the primary baseload source; as of March 22, 2026, coal-based plants held 58.2 million tonnes of stock, sufficient for an average of 19 days at an 85% plant load factor (PLF).

Transmission and Infrastructure Progress

The network experienced a healthy expansion in February 2026, adding 1,895 circuit kilometers (ckm) of transmission lines and 12,545 MVA of substation transformation capacity.

For the 11-month period (April 2025–February 2026), total transmission line additions reached 9,287 ckm against a full-year target of 15,382 ckm. While this represents a 60% achievement, the industry notes that project execution remains meaningfully back-ended, necessitating an aggressive push in the final month of the fiscal year to meet the annual target. Substation capacity additions reached 91,408 MVA (73% of the 126,007 MVA target) over the same period, providing the necessary infrastructure to reduce inter-regional congestion ahead of the peak summer load.
