A substation fire knocked out power Saturday to more than 6,000 customers in Melville, Huntington Station and South Huntington neighborhoods.
As of noon, PSEG said, all power in the area has been restored. Police continued to block a lane of traffic at the Wolf Hill and Half Hollow Hills Road intersection in front of St. Anthony's High School.
PSEG spokesman Jeff Weir said, "We're taking a look, doing diagnostic work, so we understand what the problem was and to resolve any issues that there may be."
Updated: It was the second outage for some people in the area this week. Power went out Monday in the triangle and Walt Whitman Shops area.
