A large section of downtown Honolulu is scheduled to be without power from 10 p.m. Saturday through Sunday morning as Hawaiian Electric Co. planned to replace a large underground cable.

The scheduled outage will affect the area from Nimitz Highway to Hotel Street, and from Punchbowl Street to Bethel Street.

A HECO spokeswoman said it was not known exactly when power would be restored.

Businesses and residents were given advance notice of the outage, HECO said.

Police officers were on hand to direct traffic as necessary until power is restored.
