A power outage that caused all District 95 buildings to be closed and school activities to be canceled or rescheduled was caused by two down power lines, according to Andrew Lambert, assistant principal of student life and operations.

“I’m not sure exactly what caused the power lines to go down, but I do know that there was a significant storm the day before,” Lambert said.

The power outage, which occurred August 28, canceled events such as Curriculum Night, which was supposed to be held that Wednesday.

“Dr. Walsh had to make a decision with the Superintendent on whether to hold Curriculum Night or not,” Lambert said. “When we found out that we weren’t sure when the power was going to be restored, it was at that point that they communicated out that we were going to postpone Curriculum Night.”

Lyle Erstad, the Director of Facilities and Grounds, got in touch with ComEd, who put the estimated time of power returning as 3:30 p.m. on Thursday.

“It was decided that we would not have school that day because we couldn’t have people in the building with the power down,” Lambert said.

On Thursday, Lambert, along with John Walsh, principal, Zach Gimm and Cara Obrochta, assistant principals, and Daniel Dolney, athletic director, came into work and stood by as ComEd worked on the issue.

“We worked outside, trying to work [based on] communications going out about what was happening [and] we worked with the superintendent on making decisions about extracurricular activities in the afternoon,” Lambert said.

ComEd were able to implement a temporary fix and told the administration that they were “confident that the temporary fix would not cause any further issues,” according to Lambert.

District 95 buildings were reopened and classes resumed on Friday. However, during 5th period, another power outage occurred, and temporarily put LZHS into a hold position. The power was restored that period, and the hold was lifted after around 10 minutes into 6th period.

According to Lambert, ComEd told the administration that, usually, an off-site ComEd worker would switch power through a computer system periodically in order to “create a safe working environment for ComEd workers on site.”

“What happened was [that] there was a miscommunication between the [ComEd] remote worker and the worker on site, which caused us to lose power for a short period of time,” Lambert said.

ComEd told the administration that there would be no further issues with the power following these incidents.

Curriculum Night, which was originally scheduled to take place at the time of the original power outage, was rescheduled for September 16. More information on the event can be found here.
