Sunday's widespread power outages across the Denver metro area impacted everything from the airport to 911 services, leaving nearly 180,000 customers without electricity. Xcel Energy reported issues at multiple substations as the cause, highlighting the vulnerabilities of the interconnected power grid.

Why it matters

The Denver outage underscores the growing threat of power disruptions, whether from physical attacks, extreme weather, or other factors. As the grid becomes more complex with the integration of renewable energy, ensuring grid resilience is crucial to preventing widespread and cascading failures.

The details

The initial reports pointed to a problem originating at a substation, which quickly escalated to multiple substations being affected. Substations are critical nodes in the power delivery system and are becoming increasingly targeted for physical and digital attacks. The interconnectedness of the grid means a failure at one point can quickly ripple through the system.
