Multiple Tulsa polling locations were affected by a power outage Tuesday morning in the area of 51st Street and Sheridan.
The Tulsa County Election Board officials said the outage impacted at least four polling locations.
However, voters were still able to cast their ballots during the power outage.
Officials said that voters could fill out their ballots and insert them into the locked emergency bin; at the end of the day, the bin will be opened, and ballots will be run through the machines at the affected locations.
PSO officials said almost 3,000 customers were without power.
