MUSKOGEE, Oklahoma - OG&E has been busy since Thursday working to restore power to customers from Oklahoma City to Fort Smith, Arkansas.

The utility spokesperson Kathleen O'Shea says they expect to have all customers back on line by Monday.

“Most of the affected customers should be back on before that estimate, but we want to be conservative in our estimates,” said Kathleen O’Shea

Saturday morning, OG&E says they still have just over 9,800 customers without power. The biggest outages are still in Muskogee and Sapulpa.  Other locations include Fort Gibson, Glenpool and Checotah.

O’Shea said the company brought an additional 200 crew members to help with restoration. She says the storms resulted in more than 120,000 unique outages, and at its peak 71,000 customers simultaneously experienced an outage.
