Eric Exline, public information officer for the Meridian School District, said Wednesday morning that construction crews were working on the school's remodel when heavy equipment hit a power line causing the power to go out.
Students were later moved into the gymnasium, but school officials were told power could be out for three or more hours, which prompted the district to go ahead and cancel classes for the day.
The school's 1,500 students were dismissed at about 9:30 a.m. Exline says Wednesday's closure is Meridian High's second emergency closure for the year. The school can take up to three closure days without having to make them up at the end of the year.
After school activities are still on schedule. Teachers will return to the school when power is restored.
