PORTSMOUTH, Va. (WVEC) -- Portsmouth Public Schools announced that power has been restored to I.C. Norcom High School and the school is expected to open on time Tuesday morning.

According to spokesperson Cherise Newsome, the outage was caused by a failure with the control relay switch. It's also known as a partial system failure.

Electricians worked all day to ensure the system is stable, but more repair will need to be done in coming days.

The school closed on Monday due to a total power outage. Portsmouth school officials say even the generators are affected.

"It appears to be a problem with our main switching system, which is blowing out the main power and it's also preventing our generator from kicking in. So right now no power is getting into the building at all," said Scott Ziegler of Portsmouth Public Schools.

After the decision was made to close for the day, school buses returned to their bus stops to allow students to go back home. This is also caused significant delays with middle school routes.

Two automated text messages and calls were sent to parents, alerting them of the outage delays, and then of the school's closure.

All other Portsmouth public schools are operating on a normal schedule. School officials say they don't anticipate any additional school closings, but are monitoring the situation closing.
