India Records 256 GW Peak Demand as Heatwave Strains Cities and Workers

India's peak power demand surged to approximately 256 gigawatts on 25 April 2026 as a severe heatwave spanning the entire subcontinent pushed temperatures between 43°C and 47°C across north-central and coastal regions, with the heat beginning to intensify after 20 April. Informal workers including street vendors, construction labourers, delivery riders and sanitation staff have continued to work through peak heat hours with limited institutional protection, exposing the gap between official health advisories and lived economic realities.

The India Meteorological Department has flagged above-normal heatwave days across coastal Tamil Nadu, Puducherry, Andhra Pradesh, Karnataka, Kerala and Mahe alongside the more heavily reported northern states. Maharashtra's Vidarbha region recorded temperatures close to 47°C at Akola, among the highest in the country. Schools in multiple states have adjusted hours or temporarily closed, and hospitals have reported increasing cases of heat exhaustion, dehydration and heatstroke. The heatwave is driven by a combination of strong pre-monsoon solar heating, cloudless skies and reduced Himalayan snowfall weakening natural cooling.

The crisis highlights structural inequalities in exposure to heat risk. Workers in informal and unregulated sectors including construction, manufacturing in tin-roofed facilities, gig delivery and domestic service face constant outdoor or poorly ventilated indoor exposure with no rest breaks or hydration guarantee. Homeless people lack access to cooling facilities, clean water or shelter. Urban poor communities in congested settlements with insufficient ventilation experience high indoor temperatures even overnight. Standard health advisories to stay indoors or avoid peak hours are largely inapplicable to these groups.

The author argues that India must embed climate resilience into labour law, urban planning and public discourse rather than treating extreme heat as a seasonal anomaly. Current labour codes and welfare systems were designed for a cooler climate and must be updated to protect heat-exposed workers. Heat action plans exist in some cities but implementation is uneven, especially for informal sectors. The article notes that despite heat's daily impact on millions of lives, the issue rarely shapes electoral priorities, reflecting a structural disconnect between political agenda-setting and the most climate-vulnerable populations.
