A power outage throughout the southern end of the OU campus Monday morning caused some students to miss classes and some professors to cancel lessons.

The outage occurred around 6 a.m. “due to a primary power cable fault,” said Amanda Hearn, spokeswoman for the OU Physical Plant. It lasted for over three hours until 9:40 a.m., when the plant was able to restore power. The exact cause is unknown, but the plant is looking into it, Hearn said.

Hearn did not specify which parts of the southern side of campus were affected by the power outage, but students at the OU College of Law and those living in Traditions Square East and West reported having no power.

“I knew something was wrong when I woke up to a steaming hot room,” said Chloe Meek, public relations sophomore.

Meek, a Traditions Square East resident, said she did make it to class on time because of her phone alarm.

Daniel Hensch, a third-year law student, said he missed two classes as a result. His professor for his first class on income taxes canceled the day’s lesson after learning there was no power.

“The class only meets two days a week for an hour and a half, so [its cancellation] will probably set me behind,” Hensch said. “The professor didn’t say how we were going to make up for it, but we will probably just shorten the material.”

Hensch said he skipped his 9 a.m. class thinking it would be canceled as well, only to learn later that the power came back on at the College of Law at about 8:55 a.m.

Victoria Stolfa, economics sophomore and a resident of Traditions Square East, said her alarm did not go off Monday morning because of the outages, so she missed class.

“I overslept and ended up missing my 8:30 class [Monday morning],” Stolfa said.

She said she normally wakes up at 6 a.m. to prepare for class.

After waking up, Stolfa said her computer did not work because of the outage, and she was unable to get information about the outages, communicate with her professor or finish other class work.

OU does not have an official policy on absences related to the power outage, university spokesman Jay Doyle stated in an e-mail. Doyle said, however, he thinks professors will consider the circumstances.
