OKLAHOMA CITY - A convoy of 80 OG&E crew members loaded up and headed out to Corpus Christi and other hard-hit areas affected by Hurricane Harvey. They are part of more than 3,000 personnel called in from across the country as part of relief efforts.

OG&E is part of the Midwest Mutual Assistance and Southeast Electrical Exchange (S.E.E.) In cases of widespread outages, groups like these travel across the country to assist in power restoration efforts.

American Electric Power Texas (AEP) is currently reporting more than 146,000 customers without power in its services areas. During the worst of the storm on Saturday, more than 220,000 customers were without power. According to AEP, the Corpus Christi area has the highest concentration of outages.

The Oklahoma City crews left for Rockport, Texas, at 6 a.m. Monday, and are expected to be there for a little more than two weeks.
