Delhi experienced a catastrophic power grid failure, leaving more than 300 million people across northern India without electricity. The outage originated around 2:30 PM local time and impacted users in multiple states including Punjab, Haryana, Uttar Pradesh, and the National Capital Territory. The event was primarily attributed to an imbalance in the power supply and demand, exacerbated by the growing energy consumption, particularly during the summer months when demand surges due to increased use of air conditioning and other electrical appliances.

This incident marked one of the largest blackouts in history, exceeding the 2003 blackout in North America. Millions of commuters were stranded as metro services halted, causing chaos in urban centers and resulting in traffic snarls across major roads. Additionally, hospitals faced challenges as backup generators strained to keep critical services operational.

Efforts to restore power were rapidly mobilized, and within hours, service was gradually returned to large sections of the region. However, the situation served as a wake-up call for India's energy sector, prompting discussions about the need for infrastructure improvements, better management of resources, and investment in renewable energy to meet the growing demands.
