A transformer blast at the 220 kV substation in Sector 72, Gurgaon, caused a massive blackout on the evening of May 23, 2026, as extreme heat pushed the region’s power grid to a record‑breaking demand of 2,372 MW—its highest ever. The fault, triggered by an oil leak and explosion in the current‑transfer circuit, knocked out supply from at least eight substations, halted Rapid Metro services, and left thousands of residents without fans, air‑conditioners, lifts and electricity during 42.7 °C temperatures. Officials said the explosion damaged transformer components and cascaded failures across adjoining systems, affecting major roads and the Maruti plant. Power was gradually restored by nightfall, but the incident highlighted chronic strain on NCR’s infrastructure, with similar outages reported in Noida, Greater Noida and Ghaziabad, and underscored concerns over the capacity of the state’s grid amid rising temperatures, rapid urbanisation and record electricity consumption.
