Summary

Sri Lanka experienced a nationwide electricity grid collapse on October 17, 2026, beginning around 11:45 a.m. and lasting over three hours before power was restored the same day. Reports indicate a breakdown at the Upper Kotmale hydropower station and grid instability as contributing factors, with one account citing a combination of system instability, a technical issue at a Kotmale facility, and high rooftop solar output coinciding with lower weekend demand. The outage affected all provinces simultaneously, disrupting water treatment plants, mobile connectivity, hospitals, and other essential services. The government ordered rooftop solar system disconnections to stabilize the grid during restoration. The incident exposed vulnerabilities in Sri Lanka's critical infrastructure and raised concerns about grid resilience, particularly regarding the integration of distributed solar generation into conventional electricity networks. Some officials have called for an independent investigation into the cause and circumstances of the failure.
