Con Edison spokesman Sidney Alvarez says several crews are responding to the affected buildings on 30th Street between 8th and 9th avenues.
Sections of south and east New Rochelle went dark just before 11 a.m.
At around 9:45 a.m., Con Ed said it experienced a “system voltage dip,” similar to a brownout.
Approximately 10,000-15,000 people were impacted by the outage. A power feeder cable burned out, causing the disruption.
