India’s peak power demand reached 258 GW on April 28, 2026. According to the “Extended Range Heat Wave Outlook” from the India Meteorological Department (IMD), the primary driver of this surge is the intensifying heatwave affecting Northern and Central India.
Data Breakdown: Temperature Anomalies and Demand Progression
The progression of electricity demand followed climatic conditions detailed in the IMD “Week 1” forecast for April 24 to April 30, 2026. The specific meteorological conditions reported leading up to the peak demand included:
- April 23-24: Heatwave conditions in isolated pockets of Punjab, Haryana, Delhi, West Uttar Pradesh, Odisha, Jharkhand, and Kerala.
- April 23-27: Hot and humid conditions in Tamil Nadu, Coastal Andhra Pradesh, and Coastal Karnataka.
- April 23-29: Extended heatwave conditions projected for Rajasthan.
Maximum temperatures were reported as “Appreciably above normal” (+3.1°C to +5.0°C). These anomalies were observed across Jammu & Kashmir, Punjab, Haryana, Rajasthan, Madhya Pradesh, Uttar Pradesh, Bihar, Jharkhand, Odisha, Gangetic West Bengal, Chhattisgarh, Vidarbha, Rayalaseema, Telangana, and Kerala.
Grid Response and National Capacity Profile
The national grid met the 258 GW load using the infrastructure and capacity metrics detailed in the “Ministry of Power Annual Report 2025-26.” As of December 2025, the total All India Installed Capacity was 513,729.69 MW.
The following infrastructure parameters supported the grid during the peak period:
- Transmission Network: The national power transmission network exceeds 5 lakh circuit kilometres (ckm).
- Transformation Capacity: The system includes 1,407 GVA of transformation capacity.
- Thermal Sector: As of December 2025, thermal plants maintained a coal stock of 53.5 million tonnes (MT). Cumulative biomass pellet co-firing reached 40.20 lakh metric tons (LMT).
- Hydro Sector: Capacity metrics include investment approvals for projects such as the Tato-II Hydro Electric Project (700 MW).
- Inter-regional Capacity: Under the “One Nation – One Grid – One Frequency” framework, the inter-regional power transfer capacity is 120,340 MW.
Official Statements and Administrative Oversight
The Ministry of Power leadership, including Union Minister of Power Shri Manohar Lal and Secretary Shri Pankaj Agarwal, provides oversight for sector operations and current infrastructure developments.
The meteorological basis for grid load management is the IMD’s probabilistic assessment, which indicated “High Confidence” (68-100% probability) for maximum temperature anomalies in the identified regions. Operation and maintenance of the regional grids during the peak demand period is the responsibility of the Grid Controller of India Limited (Grid-India).
