BUFFALO, N.Y. -- More than 45,000 National Grid customers lost their power after a large electrical outage Saturday morning.
All electricity came back on line before 10 a.m. Steve Brady, spokesperson with National Grid, said the exact cause of the outage is still unknown.
Most of the outages, about 36,000, were in the City of Buffalo.
Amherst, Cheektowaga, and other areas were also affected.
Brady said a piece of equipment failed at one of the large transmission substations in West Seneca. That caused problems at another facility in Buffalo.
Crews worked quickly to get power restored; now they will try to figure out what caused the equipment failure.
We reached out to National Grid Saturday afternoon and will have their answer on Channel News at 6.
As of Saturday morning, Brady could not say for sure if weather was a factor. There was strong lightning moving through the area at the time of the outage.
A phone message from Buffalo's CodeRED system informed residents of the outage and warned them to be careful at intersections without working traffic signals.
A Buffalo Police spokesperson said, "Officials remind you that any intersection where a traffic light is out should be treated as a four way stop."
Areas most affected in Buffalo include the Elmwood Village, Downtown, the University District, and the Lovejoy neighborhood, according to authorities.
