DENVER — A large power outage in the southeast area of the Denver metro on Sunday afternoon left nearly 200,000 people in the dark, affected airport operations, and 911 service in some areas.

Xcel Energy said a transformer failure and the resulting equipment damage at one of its substations just before 3 p.m. Sunday was to blame for the outage that left more than 195,000 people without power.

CORE Electric customers were also impacted.

NEW: Xcel Energy says a transformer failed at the company’s substation near Jewell/Abilene in Aurora and caused Sunday’s power outage across the Denver Metro.

Xcel says the failure damaged equipment and caused an outage that cascaded to other substations. @DenverChannel
