During the day's peak temperatures of over 100 degrees, a portion of Graham suffered a power outage.
Shortly before 4 p.m., the lights and the A/C went out around the Downtown Square and beyond, primarily west of Elm Street. Mike Nieto, Oncor's west region manager said his reports showed 426 customers were affected.
He said Oncor employees were working on a power pole containing three transformers when it fell causing the outage. Power was restored to all customers within 30 minutes.
