At least nine buildings on campus experienced power outages beginning at around 6:45 p.m. tonight due to an electrical transformer failure, according to a university-wide email from the Department of Emergency Management and Operational Continuity.

The affected buildings were Reiss Building, the Intercultural Center, Harbin Hall, Davis Performing Arts Center, Ryan and Mulledy Halls, Gervase Building, New North Building and Dahlgren Chapel.

“Due to an electrical transformer failure, it was necessary to shut down power to the … buildings while the university works to asses [sic] the issue,” the email read.

Power was restored to the buildings sequentially, beginning with the ICC at 8 p.m., Harbin at 8:20 p.m., the Former Jesuit Residence, New North and Dahlgren Chapel at 8:45 p.m and DPAC and Reiss before 9:30 p.m.

A university-wide email sent out by DEMOC at 10 p.m. said that all normal power has been restored in the buildings.

Vice President for Planning and  Facilities Management Robin Morey wrote in an email to The Hoya that several offices were involved in the recovery process. The Office of Planning and Facilities Management restored the power, DEMOC supported the recovery strategy and the Department of Safety and Environmental Management ensured laboratory safety in affected buildings.

Morey also said that electrical transformer failures are infrequent.

The fire alarm at O’Donovan Hall went off half an hour after the building experienced an outage for less than a minute. The cause of the alarm, which caused about 100 students to evacuate, has not been announced.
