Oncor is making headway to restore power after a tornado ripped through parts of Dallas and Richardson on Oct. 20.

Electricity has been restored to roughly 80% of more than 150,000 customers affected by the storm, according to Oncor. However, there are still 2,261 customers in Richardson without power, according to a map on the energy provider's website, which showed 63 active outages as of 2:30 p.m. on Oct. 22.

Power should be restored to customers living outside of the tornado's direct path by the evening of Oct. 22, a release from Oncor stated. Homes and businesses within the impact zone and without significant damage should have power by the night of Oct. 23, the release said.

A city spokesperson said Richardson officials are working to assess the damage; however, they are unable to determine at this time how many residents, homes and businesses were impacted by the storm.

Oncor reminds residents to resist removing debris and limbs from areas near downed power lines and to use caution when traveling on roadways.
