Hundreds of state employees were in the dark for two hours Friday morning as a power failure blackened the Capitol and the six-story State Office Building behind it.

Workers congregated in offices with windows, visited the cafeteria between the buildings for a long break or tried to carry on by flashlight. However, little work could be done with no power to run computers.Busloads of schoolchildren on field trips waited patiently outside or stood in the dim light of the Rotunda. A gift shop on the first floor remained open by candlelight.

Power went off at 8:25 a.m. and was restored at 10:16 a.m.

Utah Power & Light Co. crews discovered a blown fuse in the main switching box for the complex. Although power was restored, workers will have to replace the box Friday evening, turning off the power about 6 p.m., said Jack Quintana, state facilities management director. The work is expected to take eight hours.

UP&L officials said the outage did not extend to houses in the area.
