Kum & Go LC's Tulsa-area stores have resumed operations and are maintaining normal business hours, company spokeswoman Tara Deering-Hansen said Thursday.

"As long as they have power, they can stay open day and night," she said.

As many as a dozen Kum & Go stores lost power in the ice storm that struck Tulsa on Sunday.

The stores remained open during the day, but they were unable to sell fuel and could conduct only cash transactions. Some stores also had to discard perishable items.

Deering-Hansen said those stores are now running on generators or restored power.

Tulsa-based QuikTrip Corp. said its 55 stores continue to operate.

Mike Thornbrugh, a spokesman for the company, said two dozen QuikTrip locations were running on generators Thursday.

The convenience store chain is still experiencing high demand for gasoline.

Thornbrugh emphasized that QuikTrip is not experiencing a shortage but heavy demand for gasoline has caused stores to run out of fuel temporarily.

Items inside the stores are also moving fast as customers continue to buy prepared food and coffee.

"As soon as trucks arrive with fresh sandwiches and doughnuts, those items are flying off the shelf," Thornbrugh said.

Hotels remained busy Thursday, with the Renaissance Tulsa Hotel and Convention Center completely booked, said Bill Bomprezzi, director of sales and marketing.

He said demand is starting to slacken somewhat, though rooms are still hard to come by.

"A lot of people are checking out and going home, but we're still getting calls from people looking for rooms," he said.

Grocery chain Food Pyramid, which has six locations in the Tulsa area, said Thursday that it has received extra truckloads of essential items.

The merchandise includes batteries, bottled water, flashlights, firewood, fire logs and dry ice.

All of the locations were restored to power Tuesday after the company brought in large generators.

"All produce, meat, diary and frozen foods are available to customers despite the power outages," company spokesman Paul Ross said in a press release.

Also on Thursday, Farmers Insurance Group of Cos. said it had received more than 5,500 storm-related claims.
